Exposure to air pollution causes millions of deaths and loss of healthy life years annually, being considered the primary environmental threat to human health. Among atmospheric pollutants, particulate matter (PM), especially MP2,5, is particularly dangerous. Produced by combustion processes, MP2,5 is a mixture of solid and liquid particles suspended in the air, varying in composition and origin. This pollutant can cause a wide range of health problems, from respiratory irritation to severe damage in cases of prolonged exposure, including lung fibrosis, cardiovascular diseases, and neurological disorders. Global studies highlight the importance of identifying and monitoring air pollution. This research was conducted from two methodological approaches. The first aimed to analyze landscape changes in municipalities in the Northern Pantanal linked to increased deforestation and land use for livestock (appendix article) and diagnose air quality in the state of Mato Grosso based on monitoring data provided by the Environmental Secretariat - SEMA MT, Generating Article 1, which highlights air quality categorized as "good and/or inadequate," presenting air quantity on critical days, months, and annual comparisons between the years 2018 to 2023, also includes the relationship of air quality with the number of deaths from respiratory, cardiovascular diseases, and neoplasms in fifteen municipalities of MT. The second methodology was employed for laboratory analysis of quartz filter samples collected daily in Cáceres MT during a critical drought period. Collection was performed by a high-volume sampler (Hi-vol) and monitoring of meteorological data. Ninety-six samples were collected, all weighed to identify particulate matter (MP2,5) mass values, and laboratory analysis began with 20 samples to describe the chemical metals present; the results were compiled in Article 2. Article 3 was conducted from the evaluation of the 96 samples under a 40x magnification to identify and count microplastics present. According to the overall results, all municipalities exceeded the daily limits of MP2,5 established by the World Health Organization (WHO - 5 µg/m³), United States Environmental Protection Agency (USEPA - 12 µg/m³) and by the National Council for the Environment (CONAMA - 20 µg/m³). The mass concentration values of PM2.5 also showed averages above, even in large metropolises, and the metals with the highest concentrations were Na, B, Mg, Ca, Ga, La, and Fe, all indicating health risks. Therefore, the results of this study highlight the need for mitigation of necessary public policies to ensure monitoring, surveillance, and research aimed at prevention and ensuring air quality.

The Rural Environmental Registry is a legal instrument established by the 2012 Forest Code, which aims to regularize the environmental status of rural properties and preserve environmental components. For the municipality of Cáceres, Mato Grosso, land uses such as livestock farming, agriculture, tourism, etc. developed in the basin contribute to income generation, in addition to having natural components that contribute to economic diversification. The scope of this research is to analyze the effectiveness of the Rural Environmental Registry in the Piraputanga Stream Basin in Cáceres/MT, as a legal regulatory mechanism for land use and environmental conservation. The methodological procedures involved bibliographic and documentary research, application of geotechnologies, and fieldwork. The results indicated that the registry is considered by most authors as an environmental protection instrument, both nationally and in Mato Grosso. The bibliometric map of keywords related to studies on the registry indicated interest in environmental regulations in Permanent Preservation Areas, in which the main conflict of use is related to livestock farming, since it is the predominant activity in the Brazilian states analyzed in the research. It was found that in the study basin the main conflict of land use is due to the occurrence of pastures in Permanent Water Preservation Areas, constituting an environmental liability of 1.85 km², and that, of the 157 properties registered in the registry, one was validated without environmental liabilities and three are in regularization, evidencing difficulties in the implementation of the Rural Environmental Registry due to technical and operational challenges of the state management agency. It was concluded that the Rural Environmental Registry is an instrument considered effective, however its effectiveness in the Piraputanga Stream Hydrographic Basin faces challenges, and integrated actions are recommended, such as the implementation of the digital Rural Environmental Registry in the municipality, strengthening environmental inspection, forming public-private partnerships to speed up the analysis of procedures, as well as encouraging Environmental Education actions, aiming to raise awareness among owners regarding the conservation of vegetation in the basin's Environmental Preservation Areas.

Mostrar Abstract
-
The Cerrado, a savanna biome located in the central highlands of Brazil, is crucial for global biodiversity, housing about 5% of the planet's biological diversity and one-third of Brazil's biota. However, the region faces significant challenges, such as deforestation and climate change, which affect water availability and the conservation of anurans. Taxonomic diversity is an essential component of biological communities, focusing on the quantification and identification of taxa in a specific area. Functional diversity is fundamental for understanding the ecology of communities, allowing for the analysis of ecological traits and providing insights into the maintenance and functioning of ecosystems by examining how species interact and how their characteristics influence community dynamics. Phylogenetic diversity, in turn, is crucial for clarifying the relationships among taxa in a region, highlighting the importance of each species based on its evolutionary history. In this context, the order Anura, which includes toads, frogs, and tree frogs, plays a fundamental role as indicators of environmental quality. These organisms help to highlight the effects of anthropogenic changes in terrestrial and aquatic habitats, as they depend on both environments to complete their life cycle. Additionally, they have a short generation time and are essential components of food webs. This study aims to understand the responses of taxonomic, functional, and phylogenetic diversity of anuran assemblages in natural and urban environments. To this end, the research is divided into two chapters: the first analyzes the patterns of taxonomic, functional, and phylogenetic diversity of anurans in four phytophysiognomies of the Cerrado, while the second evaluates the influence of different environmental factors on the patterns of taxonomic, functional, and phylogenetic diversity of anurans in urban ponds in the city of Cáceres, an ecotone area between the Cerrado and Pantanal. Proper conservation and management of these habitats are essential to protect anuran biodiversity and ensure the maintenance of the ecosystem services they provide. Thus, our study will allow for a better understanding of the impacts of human activities on these organisms and will help identify the best conservation strategies to preserve this important group of vertebrates.

The Pantanal, one of the largest wetland systems in the world, is home to a rich biodiversity and a number of traditional communities that have in-depth knowledge of the local environment. This study focuses on the traditional ecological knowledge (TEC) about birds of the Cuiabá Mirim Traditional Community, located in the municipality of Barão de Melgaço, Pantanal de Mato Grosso, near the Chacororé - Sinhá Mariana Bay System. Using a hybrid methodological approach, combining qualitative and quantitative techniques, 21 Pantanal residents were interviewed. The results revealed a rich and detailed knowledge of 121 bird species, including information on feeding habits, habitat, appearance, behavior and the uses that the species make of the environment and that the community makes of the birds. It was also possible to draw up a complex trophic web showing the complexity of the local population's knowledge, as well as the interactions in the trophic guilds. The Pantanal inhabitants demonstrated a deep connection with nature, using an ethnocalendar that integrates human activities with the Pantanal Flood Pulse. Traditional practices, such as fishing, farming and cattle raising, are shaped by variations in water levels. The study highlights the importance of TSC as a dynamic and adaptive knowledge system, built up over generations. This knowledge is fundamental for the conservation of biodiversity and the development of strategies for the sustainable management of natural resources.

The study “The Harmful Effects of Toxic Metals on People with Cancer in the State of Mato Grosso” addresses the relationship between exposure to mercury (Hg) and the incidence of cancer in Mato Grosso, Brazil. Hg, especially in its methylated form (MeHg), is a highly toxic heavy metal that bioaccumulates and biomagnifies in food chains, being a concern in regions with intense agricultural and industrial activity. Using samples of hair, blood and nails from cancer patients, the research aims to evaluate Hg levels and explore their relationship with the development of cancer, contributing to essential data in health policies and environmental protection. In the first article, total Hg (THg) concentrations were analyzed in cancer patients in the five mesoregions of the state, with emphasis on breast cancer, which presented the highest levels of Hg, suggesting the influence of the metal as an endocrine disruptor. Areas with greater agricultural and industrial activity showed higher Hg concentrations. The study highlights the relevance of hair and nail biomarkers for chronic monitoring of metal exposure. The second article investigates exposure to Hg in the Amazon, Cerrado and Pantanal biomes of Mato Grosso. Hair proved to be the most effective bioindicator, with high levels in the Amazon and Cerrado biomes, areas of significant agricultural exploration and mining. The correlation observed between high Hg levels and breast cancer reinforces the impact of environmental contamination on public health in regions with sensitive ecosystems. This article emphasizes the need for environmental interventions to reduce Hg exposure and minimize cancer risks in these regions. In the third article, the focus is the experience of women who reconcile motherhood, academic life and personal responsibilities. Through reports, the study reflects the challenges and achievements of women, especially mothers, in the academic environment. It highlights the importance of social and institutional support networks to overcome barriers and promote equal opportunities for women in postgraduate studies. In the general conclusion, the dissertation reinforces the need for public policies for environmental monitoring and health prevention against exposure to Hg, especially for vulnerable populations. Furthermore, the study highlights the importance of institutional support for women academics, underlining that an inclusive and empathetic approach is fundamental to the advancement of science and social equality.

This work combines the results of two distinct but complementary studies that explore the relationship between agroecology principles, socio-ecological resilience, the climate crisis, and public policies. The first article refers to qualitative research conducted between 2023 and 2024 with farmers affiliated with the Regional Association of Agroecological Producers (ARPA) in the Roseli Nunes Settlement in Mirassol D’Oeste, Mato Grosso, who use Agroforestry Systems (SAFs) for agricultural production. The study investigated the presence of socio-ecological resilience principles through practices that promote diversity, adaptability, and recovery capacity in response to environmental and social disturbances in the settlement’s SAFs. The results highlight that SAFs, by integrating agricultural crops with forest species, strengthen the resilience of rural properties, ensuring greater productive stability and conservation of natural resources. The second article consists of a content analysis of the results from the campaign "Public Policies on Agroecology and Organic Production in the People’s Voice," coordinated by the National Articulation of Agroecology (ANA). The objective was to assess how climate change has been incorporated into agroecology public policies and how strengthening these policies can help mitigate the impacts of the climate crisis in areas such as food production, socio-environmental justice, and health. The analysis revealed that, although there has been progress in including agroecology in public policies, there are still gaps in explicitly integrating the topic with climate change. However, agroecology emerges as a key strategy for addressing these challenges, as it promotes resilient and sustainable food systems.The integration of both studies demonstrates that Agroforestry Systems, aligned with agroecology principles, are effective tools for strengthening socio-ecological resilience and mitigating climate change impacts. Additionally, it reinforces the need for more robust public policies that integrate agroecology as a central strategy for climate adaptation and food security, particularly in contexts of family farming and food sovereignty.

The Intestinal parasitoses are a global public health concern, with children being the most vulnerable group due to social, environmental, and behavioral factors. In Brazil, precarious sanitation conditions and a lack of hygiene education are key determinants of the high prevalence of parasitic infections. This study aimed to: (1) analyze the prevalence of intestinal parasitoses in hospitalized children in Brazil and (2) evaluate the prevalence of parasites in children admitted to the pediatric clinic of the Regional Hospital of Cáceres Dr. Antônio Fontes - SEDE (HRCAF-SEDE) during the rainy and dry seasons of 2024. The first part of the study involved a systematic literature review conducted using scientific databases such as PubMed, Scielo, and CAPES, covering articles published between 2013 and 2024. Twelve studies exploring the prevalence and associated factors of parasitic infections in children were analyzed. The findings indicated that health education initiatives and improvements in basic sanitation are effective in preventing these infections, contributing to reduced infant morbidity rates. However, the review identified a lack of longitudinal studies and limitations in generalizing findings due to regional disparities, highlighting the need for further research to expand knowledge and support more comprehensive public policies. The second part of the research was a cross-sectional study conducted at the Regional Hospital of Cáceres Dr. Antônio Fontes – SEDE. The study assessed the prevalence of parasites in hospitalized children during the rainy and dry seasons of 2024. Parasitological data were collected through stool examinations and complemented by socio-environmental information obtained via interviews with the children's caregivers. Data analysis from 60 children revealed that 55% had parasitic infections, with 75% of cases caused by protozoa and 25% by helminths. The age group of 0 to 4 years exhibited the highest prevalence, and cases of polyparasitism accounted for 60.61% of diagnoses. The annual prevalence of protozoan species was recorded in descending order as follows: Endolimax nana (n=23; 38.3%), Blastocystis spp. (n=18; 30.0%), Giardia spp. (n=12; 20.0%), Chilomastix mesnili (n=6; 10.0%), Entamoeba coli (n=3; 5.0%), and Entamoeba histolytica (n=1; 1.7%). The only helminths identified were Ascaris spp. (n=3; 5.0%), detected through the presence of infertile eggs, and Hymenolepis nana (n=1; 1.7%). Although no statistically significant differences in prevalence were observed between the seasons, the results suggested higher vulnerability during the dry season. This lack of seasonal differences highlights the need for continuous and permanent preventive measures. Factors such as low family income and low parental education were significantly associated with parasitic positivity, reinforcing the impact of socioeconomic conditions. This study emphasizes the necessity of integrated strategies combining health education, sanitation improvements, and socioeconomic interventions to mitigate parasitic infections in children. Improving child health requires adopting multidisciplinary approaches and public policies that address regional inequalities and social determinants, ultimately promoting more equitable and sustainable health outcomes.

Environmental issues and the integrated management of solid waste have mobilized different sectors of society, highlighting the importance of selective waste collection and the crucial role played by recyclable material collectors. This research stems from the following question: What is the interplay between Environmental Education and the selective waste collection carried out by recyclable material collectors within the Consórcio Complexo Nascente do Pantanal (CCNP)? The motivation for this study lies in the relevance of Environmental Education as an instrument for social change, as well as the fundamental role that collectors play in integrated waste management and their connection to sustainability. The theoretical framework is based on concepts of Environmental Education, urban solid waste, the National Solid Waste Policy (PNRS), and selective collection, emphasizing community awareness and empowerment. It also includes an analysis of the socioeconomic profile of collectors, considering their working and living conditions. The methodology involves qualitative research, including semi-structured interviews and questionnaires applied to the recyclable material collectors of the Associação Ambiental Reciclar (AACR). Additionally, a document analysis of Environmental Education programs and projects in the CCNP's Integrated Management Plan reveals the complexity of the collectors’ reality, highlighting gaps between proposed Environmental Education programs and their actual effectiveness in the daily lives of these workers. There is a clear need for greater integration between public Environmental Education policies and the practices of recyclable material collectors, reinforcing the transformative potential of education to promote not only selective waste collection but also social inclusion and the strengthening of environmental citizenship. The dissertation is structured into an introduction, Manuscript I and II, and final considerations

This dissertation explores the perceptions of nursing faculty members in the city of Cáceres, Mato Grosso, Brazil, regarding the promotion of environmental health, advancing a perspective that transcends the traditional hospital-centered model. The study is grounded in the understanding that environmental disruptions—such as climate change, pollution, and ecosystem degradation—have direct impacts on human health and call for reoriented health education, particularly within the field of nursing, which plays a pivotal role in primary care and health education. The research adopts a critical approach that frames environmental health as an integral component of public health and planetary sustainability.
The investigation was conducted in two main phases. The first involved a systematic review of the scientific literature, analyzing publications indexed in the BVS, LILACS, and MEDLINE databases between 2019 and 2024, using descriptors related to environmental health education in nursing training. Findings revealed a scarcity of scholarly work on the subject, highlighting both the limited integration of environmental issues into nursing curricula and the absence of institutional policies that support sustainability-oriented pedagogical practices.
The second phase comprised an exploratory-descriptive qualitative study involving 34 nursing faculty members from two higher education institutions in Cáceres-MT. Data were collected through structured questionnaires and analyzed using Bardin’s content analysis method. Results indicated that although faculty members acknowledge the importance of environmental health, nursing education remains predominantly shaped by a biomedical, hospital-focused paradigm. Participants emphasized the need for increased professional development and curricular reform to better address environmental health concerns.
In light of the pressing global environmental crisis, this study underscores the urgent need to reconfigure nursing curricula and educational practices by positioning environmental health as a core dimension of professional training. The dissertation ultimately advocates for the empowerment of nurses as agents of social transformation, capable of promoting care practices committed to human health, environmental justice, and the sustainability of life on the planet.

The dissertation ‘Environmental and social determinants and the perception of quality of life in a vulnerable community in the Mato Grosso Pantanal’ addresses the complex relationship between public health, socio-environmental conditions and parasitic diseases in vulnerable populations in the municipality of Cáceres, Mato Grosso, Brazil. Using an interdisciplinary approach, the studies presented analyze how environmental factors, such as poor sanitation and proximity to water bodies, are associated with the occurrence of enteroparasitosis and the perception of quality of life in low-income communities. This dissertation is structured into two distinct articles. The first article presents an analysis of the prevalence of enteroparasites among residents of a peri-urban neighborhood in the municipality of Cáceres, correlating the parasitological findings with socioeconomic and environmental factors. The results indicated a higher prevalence of Ascaris lumbricoides, suggesting the persistence of transmission cycles linked to soil contamination and inadequate sanitation infrastructure. The second article aimed to explore the perception of quality of life in relation to socio-environmental conditions in this same vulnerable peri-urban Community. The analysis revealed that, despite deficiencies in basic sanitation and low income, the perception of well-being was high, highlighting the role of social networks and the feeling of community belonging in the subjective construction of quality of life. The thesis highlights the urgent need for structural interventions in the communities studied, aimed at improving sanitary conditions and public health.

The study addresses Environmental Education (EE) as a fundamental formative axis from the earliest years of schooling, highlighting its relevance in the face of the global socio-environmental crisis and, more specifically, within the context of the city of Cáceres (MT), located in the Pantanal biome. The objective is to investigate pedagogical practices related to EE and how they are implemented in the school routine, analyzing the challenges teachers face in integrating such practices into the curriculum in a systematic and meaningful way.
The guiding justification of the work lies in the urgent need to educate environmentally conscious and socially committed individuals, especially in regions of rich biodiversity and environmental vulnerability, such as the Pantanal in Mato Grosso. Environmental Education, in this regard, should not be seen as an isolated or occasional subject, but rather as a transversal and continuous dimension, permeating all areas of knowledge and being incorporated into the schools’ Political-Pedagogical Project (PPP).
The methodology adopted involved two stages of study, which included the application of questionnaires and semi-structured interviews with teachers from Early Childhood Education and Elementary Education I in public and private institutions in Cáceres. Data collection adhered to the ethical procedures required by the Research Ethics Committee of UNEMAT. The first article was based on the analysis of responses from 14 teachers through a questionnaire, while the second deepened the qualitative analysis through interviews with the same group, aiming to capture the teachers’ understanding of EE, the pedagogical practices adopted, and the challenges faced in their implementation.
Among the main findings, a generalized understanding among teachers about the importance of EE stands out, especially concerning environmental preservation. Reported practices include group discussions, use of educational videos, posters, playful activities, and institutional projects. However, the articles also reveal significant barriers: lack of specific ongoing training, shortage of resources and teaching materials, bureaucratic hurdles that hinder field classes, and lack of institutional support.
Another important point revealed in the interviews is that although teachers show individual initiative in addressing environmental topics, the absence of public policies and coordination with environmental agencies weakens the effectiveness of these actions. The reports indicate that many of the practices still occur sporadically, often limited to commemorative dates, lacking a continuous pedagogical plan that integrates EE in a critical, emancipatory, and contextualized manner.
In summary, the study advocates for the centrality of Environmental Education in the development of citizenship and points out that its effective integration requires not only teachers’ willingness but also adequate training, public investment, community participation, and meaningful integration with local contexts. EE, when understood as an ethical, epistemological, and political practice, becomes a powerful tool for building a sustainable, equitable, and resilient society.

Natural regeneration is an essential process for forest renewal, and is directly influenced by biotic and abiotic factors that determine which species can establish themselves in a given location. In recent years, fires in the Pantanal have become more frequent and intense, which can significantly alter the composition of the vegetation. This study aimed to understand the natural regeneration and floristic composition of vegetation after fires in polyspecific forests located in the Taiamã Ecological Station. The study was conducted in two 1-hectare plots (40 m x 250 m) established in polyspecific forest areas. The tree vegetation was reassessed in 2023, after the fires that occurred in 2020, considering individuals with CAP > 15 cm throughout the plot area. The survey of natural regeneration (individuals with height < 2 m) and young individuals (height > 2 m) was carried out, respectively, in 50 subplots of 2 x 2 m and 10 subplots of 20 x 25 m, distributed in each plot. In the first survey, 408 and 637 adult individuals were recorded in areas 1 and 2, while in 2023 these numbers were reduced to 233 and 150 individuals, respectively. As for regenerants and young individuals, 523 and 1,148 regenerants, and 304 and 243 young individuals were recorded in areas 1 and 2, respectively. The most important species in the surveys were Zygia inaequalis, Spondias mombin, Trichilia catigua, Cassia grandis, Genipa americana, Triplaris americana and Cecropia pachystachia. In common to the three strata analyzed (adults, young and regenerants), 9 species were identified in area 1 and 7 in area 2. The distribution of individuals by height and diameter classes maintained the inverted “J” pattern, as expected in areas in natural regeneration. However, understanding the effects of fire in conserved areas is essential to support management actions and guide ecological restoration strategies.

The Pantanal is the largest continuous floodplain on the planet, renowned for its biodiversity and international recognition. Spanning two Brazilian states and extending into other South American countries, it provides habitat for numerous species and plays a critical role in ecosystem services. However, the biome faces constant threats, including large-scale wildfires, whose severity has increased in the Brazilian Pantanal, causing significant impacts on biodiversity, the hydrological cycle, and traditional livelihoods. The Estação Ecológica de Taiamã (ESEC Taiamã), a federal protected area located in the Mato Grosso Pantanal, was severely affected by the 2020 and 2024 fires. In this context, it is essential to apply technologies and methods capable of understanding environmental changes and monitoring ecosystem regeneration, especially given the scarcity of monitoring and restoration initiatives in Brazil. Geotechnologies have proven to be promising tools in this regard. This study is structured into two articles. Article 1 aims to evaluate how geotechnologies can contribute to the identification and analysis of burned areas in ESEC Taiamã, applying various environmental monitoring techniques to support ecological restoration strategies. Article 2 focuses on characterizing the different macro-hábitats within the conservation unit, quantifying the burned area in each macro-hábitat and integrating these data with field surveys of vegetation. By comparing burned and unburned areas, the study assesses floristic composition, vegetative vigor, and fire severity, highlighting the impacts of burning on local biodiversity. The integration of remote sensing, GIS, and field data enhances the understanding of post-fire dynamics, providing support for Integrated Fire Management (IFM) and identifying priority areas for ecological recovery and restoration. The results offer important insights for the management of ESEC Taiamã and support the development of public policies aimed at conservation, fire management, and ecological restoration in the Pantanal.

This paper characterizes a biocultural corridor influenced by the Cuiaá and Paraguay rivers in the Pantanal Biosphere Reserve (RBPA) in Mato Grosso, as presented in Chapter 1. Chapter 2 highlights the fires that occurred in this corridor between 2020 and 2024. The final considerations address the potential of this biocultural corridor for strategic and shared management of the challenges faced and solutions implemented in the region. The RBPA is of global importance, encompassing the largest continuous wetland on the planet. The RBPA designation, conferred by UNESCO, aims to ensure the conservation and use of biodiversity in regions of great ecological, economic, and social value worldwide. In Mato Grosso, more than 90% of the RBPA is located within the Upper Paraguay Basin (BAP), bordered by plateaus and mountain ranges, with the Pantanal floodplain to the west. While representing a territory of extreme importance for biological diversity and hydrological regime, the Pantanal also boasts unparalleled richness and sociocultural complexity. This occupation is not only a record of human presence in the Pantanal, but also a testament to these peoples' ability to adapt and coexist with the region's natural dynamics, where traditional knowledge and cultural practices play an essential role in maintaining biodiversity and the sustainable management of natural resources. The historical socio-environmental context in the Pantanal is complex, challenging, and permeated by conflicts related to land use and occupation, with highlights including disputes over land and water, impacts from hydroelectric and mining projects, deforestation, fires, and the abusive use of pesticides resulting from agricultural practices. In recent years, especially between 2020 and 2024, fires devastated almost half of the entire Pantanal biome. In contexts such as this, of high environmental heterogeneity and cultural diversity, studies and initiatives have highlighted the potential of the biocultural corridor approach. A biocultural corridor can be defined as a region where nature and culture are intrinsically linked. The proposal to develop a territorial planning and management strategy with a special emphasis on biocultural corridors as a safeguard for the common assets of nature and communities could be a successful step toward conserving this region of the Pantanal Biosphere Reserve. Delimiting the territorial boundaries of this biocultural corridor could be complemented by participatory and social mapping, in a dynamic process that seeks to build consensus and solutions that benefit both biodiversity and sociodiversity. The results showed that the corridor covers 4.9 million hectares and connects five geomorphological units: plateaus, terraces, depressions, floodplains, and mountains. It is located within the Paraguay Hydrological Unit, encompassing part of the Paraguay River and a large portion of the Cuiabá River, with its headwaters, in the Cerrado biome. Mapping of priority areas for biodiversity conservation revealed areas of very high and extremely high conservation importance, including four types of sites recognized by UNESCO: a Biosphere Reserve, three Ramsar sites, a World Heritage Site, and a proposed Chapada dos Guimarães Geopark. Consequently, the region has thirty Conservation Units. From a cultural perspective, the region is occupied by indigenous peoples, the Bororo and Guató ethnic groups, quilombolas, traditional communities, and family farmers. Driving forces in the RBPA, such as large-scale agriculture and livestock farming, mining, hydroelectric dams, and land speculation, have created pressures such as deforestation, fires, pesticide contamination, mercury, and river silting. The biocultural corridor arc, influenced by the Cuiabá and Paraguay rivers, in the Pantanal Biosphere Reserve, presents a complex geomorphological configuration resulting in ecosystem diversity that supports a rich biodiversity and, at the same time, provides the basis for the subsistence, knowledge, and cultural identity of the traditional peoples and communities present in this corridor, making the conservation of these geomorphological landscapes a biocultural imperative. The fires from 2020 to 2024 impacted 4 million hectares in this corridor, with 56% of its area burning at least once during this period. The average annual area affected by fires during this period was 808,000 hectares, which is equivalent to 16.5% of the total area of the biocultural corridor (4 million hectares) being affected annually by fires and fires. The category with the highest incidence of fires was registered private rural properties, where practically 60% of the areas affected by fires occurred from 2020 to 2024. Conservation units were the second most affected by fires in the biocultural corridor from 2020 to 2024 (22.97%). The impacts on the population living in rural settlements and indigenous lands, as well as in urbanized areas within the biocultural corridor, were enormous. 92.1% of the burned area was naturally occurring, including forest formations (22.88%), savannahs (25.18%), grasslands (22.07%), flooded fields and marshes (17.22%), and vegetation in watercourses and lakes that have dried up (4.61%). The remaining 7.9% affected were areas of anthropogenic use, mainly occupied by pastures (6.74%). The scenario of areas affected by fire in recent years in this biocultural corridor represents the current urgency for prevention and mitigation actions against the occurrence of fires. These actions must be strategically coordinated and implemented in an integrated manner by various actors. In the context of the Pantanal Biosphere Reserve, by focusing on a smaller set of municipalities or sub-basins, biocultural corridors become more manageable, participatory, and efficient, facilitating the integration of environmental conservation and cultural appreciation in the daily lives of the people who live and care for these territories. This approach can enhance extremely promising practices for fire management in the Pantanal Biosphere Reserve, especially given the intensification of droughts and the increase in fire occurrences. We therefore emphasize the implementation of biocultural corridors as a strategy to protect the Pantanal from devastation by fires, by recognizing and integrating the communities' ancestral knowledge and practices into the management of the biome.

Changes that occur in hydrological periods such as seasonal floods and prolonged droughts can alter physical-chemical variables, affecting the diversity and abundance of aquatic macrophyte communities in the Pantanal Matogrossense. Aquatic macrophytes are submerged or partially submerged plants, which are the main producers of organic matter and play a vital role in the cycling of nutrients, habitat and food for the aquatic ecosystem. The objective is to investigate the dynamics of the physical-chemical and phytosociological variables of aquatic macrophytes as a function of the variation of hydrological regimes in the functional sectors of the Paraguay River in the municipality of Cáceres-MT. Sampling took place during the hydrological periods of flood, high water, low water and drought in 2023 and 2024 between the Paraguay River Ecological Corridor and the Taiamã Ecological Station, comprising the meander, rectilinear, transition and fluviolacustrine sectors, using the RAPELD method in 5 km transects, subdivided into ten 500 m modules. The community was assessed using the Braun-Blanquet method with 0.50 x 0.50 cm squares to measure the percentage of coverage and were identified according to Pott & Pott (2000). The influence of limnological, spatial and temporal variables on the composition and production of dry biomass on the accumulation of phosphorus and total nitrogen nutrients in the morphological structures of the species Eichhornia azurea in the transition (TC) and fluviolacustrine (T2, T3 and T5) sectors was also evaluated. 30 families, 47 genera distributed in 68 species were recorded, most of which are classified as "Data Deficient" or "Least Concern" and are listed on the IUCN Red List. The analyses showed that aquatic macrophytes registered similar groupings in terms of diversity and similarity in community composition. The occurrence of diverse species among the functional sectors, with emphasis on the fluvial-lacustrine sector, influenced by hydrological periods of flood and drought. These conditions favored the life forms of the species, with a predominance of emergent and amphibious species. The dry biomass production of E. azurea was influenced by the hydrological flood period, with greater production allocated to the aerial part. Nutrient accumulation varied according to hydrological periods and spatial segregation in area T2. The greatest accumulation of nitrogen occurred in the aerial parts and necromass during the flood season, while phosphorus was predominant in the roots during the dry season. The limnological variables showed variations in an increase or decrease in depth, oxygen saturation, electrical conductivity, transparency and the concentrations of phosphate and nitrogen nutrients. It was concluded that there is a high richness and diversity of species, highlighting the role of E. azurea in nutrient cycling. We emphasize the importance of additional studies to deepen the understanding of the floristic composition and seasonality of some species of aquatic macrophytes, with a focus on conservation in the Pantanal biome.

The Amazon is home to an extremely rich biological diversity, made up of different types of vegetation, such as terra firme, várzea and igapó forests, forming a mosaic of habitats that reflect its heterogeneity and areas of endemism. Occupying around 40% of Brazil's territory, the forest has a climate cycle marked by periods of drought and rainfall, which directly influences its structure and the dynamics of the species that inhabit it. Approximately 73% of Brazil's mammals occur in the region, with primates standing out for their essential ecological role in maintaining biodiversity, especially in dispersing seeds and structuring vegetation. The behavior of primates is directly influenced by ecological factors, such as the availability of resources, habitat characteristics and climate patterns, as well as being impacted by anthropogenic activities. Human presence, whether through deforestation, hunting or even activities such as ecotourism, can lead to changes in the behavior and use of space of these animals. When well planned, ecotourism can be a conservation tool, but it also poses risks if its impacts on local fauna are not taken into account. Among the Neotropical primates, the spider monkeys of the genus Ateles stand out for their high dependence on large forest areas, due to their large body mass (~9kg), their predominantly frugivorous diet and their social system forming groups and subgroups by fission-fusion. Ateles marginatus, known as the white-faced spider monkey, is an endemic species of the Tapajós-Xingu interfluve, highly sensitive to forest fragmentation and human activities. The species is considered endangered, and knowledge about its behavioral ecology is still limited, especially in continuous forest environments. Given this scenario, this dissertation is structured in two chapters. The first looks at the behavioral ecology and diet of Ateles marginatus in an area of continuous forest in the Cristalino RPPN, in the southern Amazon. The second chapter investigates the use of space and the possible effects of ecotourism, especially the presence of trails, on the movement patterns of the species, seeking to understand how tourist activities can influence the behavior and daily routes of these primates.

The science in which this work is inscribed is ethnobotany. This area of knowledge is concerned in understanding how human groups relate and explain the plants, their attributes, materials and immaterial, present in their ways of life. The objective is to record knowledge about the plants kept in cultivation spaces (yards and gardens) in the neighborhoods of São Jorge and Lobo, city of Cáceres, Mato Grosso, Brazil. For the selection of interlocutors, we used the "snowball" sampling technique, allowing access to the research subjects and their experiences. Data collection took place through a semi-structured form, with open and closed questions, supplemented by field observations, notebook notes, photographic records and the interviews were recorded in audio, and transcribed later. The research was carried out with 17 participants from different backgrounds, being: 13 people from the state of Mato Grosso, highlighting the main aspects of ethnoknowledge: inherited knowledge from older, use and cultivation of medicinal plants, care practices in urban backyards and gardens, cultivation as a therapeutic form and family memory. In relation to gender, the presence of 13 women stood out among the interviewees, while four were men. 103 species belonging to 41 botanical families were recorded, all confirmed by vouchers collected in 17 yards and three urban gardens. The interviewees in both neighborhoods not only share their knowledge, but also emphasize the importance of conserving and valuing it as a cultural legacy and resistance of living memory in the urban context. This strengthens the heritage and sustainability, highlighting the main aspects of ethnoknowledge: the transmission of transgenerational knowledge by orality, connected to the use and cultivation of ornamental plants, medicinal plants, planting for human consumption; medicinal use for domestic animals and those that generate thermal comfort. This knowledge demonstrates the importance of urban backyards as sites of cultural, social and environmental preservation.

The history of the struggle for the survival of Indigenous peoples is part of the agenda of resistance movements, which have become increasingly active in recent times in response to external capitalist pressures and internal demands related to health, education, sociocultural reproduction, and territorial issues, among others. The annihilation and extermination promoted by the logic of integrationist development in the Legal Amazon have left deep scars on both nature and the memory of the Tapirapé Indigenous people, who self-identify as Apyãwa. The central objective of this thesis was to analyze how the capitalist expansion of agricultural, urban, and industrial frontiers has affected the traditional way of life of the Apyãwa (Tapirapé) people of the Urubu Branco Indigenous Land, located in the state of Mato Grosso, in the Midwest region of Brazil. To achieve this, the study was structured into four sections, presented in the form of articles, using a qualitative approach. The first article, based on an extensive bibliographic review of historical reference materials, describes the socio-territorial trajectory of the Apyãwa people from the 16th century onwards. It examines their early interactions with non-Indigenous society and the consequent population decline that occurred in the mid-20th century. The findings suggest that they migrated from the Brazilian coast in the 16th century and, after several displacements, were already inhabiting the surroundings of the Serra do Urubu Branco, located in the northeastern region of Mato Grosso. Around the year 1900, their population was estimated at 1,500 individuals. However, after their first contacts with non-Indigenous people (starting in 1910), this number was drastically reduced, reaching only 47 individuals by 1952. The second article addresses the process of demographic, sociocultural, and territorial revitalization, focusing on the influence and participation of the religious sisters from the Fraternity of the Little Sisters of Jesus among the Apyãwa people. In 1952, these sisters began living in the village and remained there for 65 years. Historical records and interviews with 27 Indigenous people indicated that their presence was crucial to the survival of the community. They provided healthcare, helped maintain social cohesion and territorial integrity, initiated the fight for Indigenous rights, and fostered a sense of fraternal coexistence. The third section explores the process of deterritorialization and reterritorialization of the Tapirapé people, who were forced to abandon their ancestral territory in 1947. After successive displacements and relocations, the Apyãwa launched a collective movement of struggle and resistance, which culminated in the reclamation of their ancestral territory in 1993. However, they found it severely degraded due to environmental impacts caused by large landowners. Finally, the fourth article examines the major changes in the Apyãwa people's way of life following the reclamation of their ancestral territory. In particular, it analyzes transformations since 1993 and how their modus vivendi has evolved to the present day. The use and occupation of their territory by agribusiness enterprises led to significant deforestation, forcing them to modify their traditional way of life. The perspectives of interviewed Indigenous individuals reveal the necessity of reshaping their living space—adapting the environment, social systems, economic activities, and ceremonial and ritual practices. As general conclusions, the thesis finds that, despite being uprooted and on the brink of extinction, the Apyãwa survived, multiplied, and continue to resist. Through a movement of struggle and resistance, they reclaimed their ancestral land and are collectively seeking alternative strategies to sustain their traditional, social, cultural, and spiritual way of life. Their trajectory teaches a valuable lesson about resilience and the importance of Indigenous self-determination.

The state of Mato Grosso encompasses the Amazon, Cerrado, and Pantanal biomes, presenting a vast diversity of fish, reptile, and mammal species. However, in recent decades, biological diversity has been eroded by the intensification of anthropogenic activities that have increased since the 1980s with the expansion of agricultural frontiers promoting deforestation, especially in the upper course of the Paraguay River. Changes in land use and cover are among the forces driving habitat transformation, reduction, and loss. Ecological connectivity and environmental changes affect the quality of food resources and habitats for fish, lizards, and mammals. The anthropized environment causes species displacement, altering ecological dynamics, trophic relationships, and energy flows in ecosystems, besides directly influencing diet and mercury bioaccumulation. To understand long-term diets, we used isotopic analyses that reveal trophic position, habitat preferences, and mercury bioaccumulation patterns. It is crucial to comprehend how habitat modification and fragmentation influence mercury flow in ecosystems because landscape alterations lead to changes in diets, bioaccumulation, and mercury detoxification. The distribution and accumulation of mercury impact wildlife diversity, which faces an environment of climate change and new land uses and cover. To investigate these changes and their impacts, we utilized satellite image analyses and measurements of total mercury content and stable isotopes of carbon (δ13C) and nitrogen (δ15N). Stable isotopes, including δ13C and δ15N, are fundamental for understanding ecological dynamics, trophic relationships, and variations in feeding patterns, offering valuable insights into the ecological niches of organisms. Understanding how mercury is absorbed and distributed through food chains is essential to interpret the impacts of anthropization and the mobilization of total mercury (THg), which presents an accumulation pattern from upstream to downstream in the upper course of the Paraguay River, with greater bioaccumulation at the Taiamã Ecological Station. These markers offer an integrated view of land use and cover, habitat foraging patterns, and bioaccumulation, enabling the tracking of mercury sources in the environment.

The Amazon is one of the most biodiverse tropical forests in the world and plays a crucial role in maintaining global ecosystems. However, despite its biological and ecological importance, The Amazon faces unprecedented threats, including habitat fragmentation, loss and degradation, especially in the "Arc of Deforestation". As the frontiers of destruction advance, more than 18% of the original forest cover of the Brazilian Amazon has been converted into anthropized habitats. The state of Rondônia in Brazil is a striking example of this rapid and drastic reduction in native habitats. Therefore, in this thesis, using different methodological approaches, we evaluate the causes and effects of human modifications to the landscape of an important endemism zone in the Amazon and for the state of Rondônia. This thesis is structured in three chapters: in the first, "The spatio-temporal dynamics of vegetation cover and its configuration reveal an imminent threat in an Amazonian state", we examine the spatio-temporal change in Rondônia's vegetation cover between 1986 and 2020, using satellite images and landscape ecology metrics. Over the course of 35 years, there was a drastic reduction of 28.2% in Rondônia's vegetation cover, generating more than 100,000 fragments of natural vegetation with an average size of 150 hectares and a high degree of isolation. In Chapter 2, entitled "Under pressure: the rapid decline of bird and mammal diversity in an Amazonian endemism zone", we investigated how fragmentation, habitat loss, and environmental degradation can modulate bird and mammal communities in a little-studied endemism zone in the Amazon. We found that the effects of habitat and landscape act in combination in the 42 bird and mammal taxa. On the landscape scale, taxonomic and functional completeness was affected by the distance from the largest remnant in the region and by the proportion of agribusiness. At the habitat scale, completeness was modulated by fragment size, vegetation height, selective logging, and forest fires. In Chapter 3, which is still under construction, we intend to verify how changes in habitat and landscape affect the behavior of mammal species in a severely deforested and fragmented landscape, in terms of interspecific association and activity period.

The study was carried out in the middle course of the Itapecuru river in the municipality of Caxias in the state of Maranhão. Aiming to verify the environmental components, morphometric parameters, forms of land use/occupation and impacts and hydromorphodynamics in the middle course of the Itapecuru river basin in the municipality of Caxias in Maranhão. The methodological procedures used to carry out the research were based on office work, field work and laboratory work. To characterize the geoenvironmental units, secondary data was used through technical manuals from the main research centers in Brazil (IBGE, Embrapa, CPRM and Inmet). The database was processed using geotechnology tools and finally data post-processing that corresponded to adequacy and standardization. The morphometric parameters were obtained through formulas and reference standards. To overlay the information, the ArcGis 10.8 software was used. To verify the evolution of morphological features along the longitudinal profile, Google Earth image mosaics from the years 2010 and 2020 and geotechnology tools were used, which allowed the quantification of the features. The aerial photographs were obtained using the Mavic Air model drone. To carry out this analysis of use and coverage, the image mosaic from MapBiomas, collection 5 of the year 2021 was used. Likewise, the production of the air suppression map natural vegetation and regeneration occurred with the acquisition of MapBiomas raster data, collection 6 from the year 2022. To identify environmental impacts on urban river channels, rapid assessment protocols and the protocol for evaluating morphological parameters in river channels were used. To obtain the hydrodynamics, some steps (office, field and laboratory activities) were necessary. Office work begins with the construction of the theoretical framework, preparation of the cartographic base and data tabulation and writing. The field work involved collecting hydrodynamic data in the middle course of the Itapecuru River, which was measured on fifteen cross-sections distributed along the longitudinal profile, during the flood and dry periods. To measure the bathymetry he used the GARMIN echo sounder, to measure the flow velocity he used the fluviometric windlass and turbidimeter to obtain the turbidity. To collect sediment, a Van Veen dredger was used. Flow rates were obtained using formulas. Photographic records were taken with a camera and an unmanned, remotely piloted aircraft (RPA) with a cell phone attached. The laboratory work consisted of checking the types of sediment transported and deposited in the river channel, with particle size analysis being carried out using the pipetting method – total dispersion to fractionate the bottom material. The results show important information about the middle course of the Itapecuru river basin in the municipality of Caxias. In relation to environmental aspects, the area is located in the climate transition zone, on the Tropical Equatorial Zone; the geological formations present in the study area are the Corda Formation, Motuca Formation and Sardinha Formation, the Alluvial Deposits and Post-Barreira Sediment Unit and the Barreiras Group and Itapecuru Group; the geomorphological units mapped are four units, with emphasis on the Caxias Patamar and the occurrence of five types of soil, with emphasis on Concretionary Pétric Plintisols. The recorded vegetation is divided into seven registered three classes of vegetation cover with a predominance of the Submontane Deciduous Forest. Regarding morphometry, the basin has 183 channels, being considered a 5th order basin. 109 first-order channels, 41 second-order channels, 28 third-order channels, 4 fourth-order channels and 1 5th-order channel were recorded. The total length of the canals was 1,004.77 km. The values recorded for the shape factor, compactness coefficient and circularity index allowed us to conclude that the drainage network has an oval shape, with a medium tendency to flood. The sinuosity index recorded was 1.29 km, indicating a tendency towards straight channels. The circularity index recorded was 116.23. The capacity coefficient was 0.56. The channel density registered 0.03 km², which indicates low capacity to generate new channels. The drainage density recorded was 0.29 km². It recorded temporal changes in morphological features in the river corridor, such as: increase or reduction in the size of features, emergence of new features and disappearance. Ten units of use and coverage were diagnosed, such as: Forest Formation (1,665.44 km²), Savanna Formation (1,254.37 km²), Forestry (1.69 km²), Countryside Formation (158.89 km²), Pasture (293, 40 km²), Urban Infrastructure (22.70 km²), Other Non-Vegetable Areas (28.60 km²), River and/or Lagoon (2.37 km²), Soy (1.28 km²) and Other Temporary Crops (0.91 km²). The mapping of temporal change in land use and cover between 1985 and 2021 revealed: an increase in pasture areas, deforestation and regeneration. The analysis of degradation in the urban perimeter channels of the City of Caxias obtained the following parameters: natural, impacts and altered according to protocol. In the first channel, it was found that points (1, 2, 4 and 5) were impacted and points (3 and 6) registered changes. In the second channel, point 1 was natural, point 2 was impacted and point 3 was altered. In the third channel, all analyzed points are impacted. In the fourth channel, point 1 was natural. In the fifth channel, it was impacted due to being channeled and rectified. Hydrodynamic data differ throughout the year. During drought, the hydrodynamic data are as follows: the section areas varied between 16.32 m² and 158.00 m²; average depths ranged from 1.10m to 3.10m; channel widths ranged from 24 m to 51 m; average flow velocities ranged from 0.242 m/s to 0.824 m/s; flow rates in the sections varied from 13.45 m³/s-¹ to 41.75 m³/s-¹ and turbidities varied between 14.00 UNT and 21.30 UNT. At flood, the section areas varied between 152.81 m² and 310.96 m²; the average depths varied between 4.13m and 6.76m; channel widths ranged from 27m to 51m; the average flow velocities varied between 1.12 m/s to 1.223 m/s, the flow rates varied between 89.69 m³/s-¹ to 287.45 m³/s-¹ and the turbidity indices varied between 30.40 UNT at 39.40 UNT. The granulometry of the sediments showed the predominance of fine sand in both periods (flood and drought). During drought, the variation of fine sand was from 93.2% to 99.15%. At flood, it varied between 65.95% and 99.7%.

Mercury (Hg) is a global pollutant and ranks among the top ten most harmful pollutants, being the third most concerning for human health. In biota, especially in aquatic biota, Hg causes neurological, physiological, and reproductive adversities. Aquatic environments, particularly lotic systems such as hydroelectric reservoirs, amplify contamination by this metal. The global and Brazilian energy demand has led to the creation of numerous hydroelectric power plants, including four plants with large cascading reservoirs on the Teles Pires River, a tributary of the Tapajós Basin in the Brazilian Amazon. Contaminations by Hg were analyzed in predatory and non-predatory fish, sediments, and soil downstream and in the Sinop, Colíder, Teles Pires, and São Manoel reservoirs. This study also includes control points on the Teles Pires River and the Juruena River. This thesis is presented in two articles and aims to evaluate the effect of hydroelectric reservoirs on fish, sediments, and soil. The first article presents an analysis of Hg contamination in predatory and non-predatory fish from the four hydroelectric reservoirs on the Teles Pires River. Predatory fish downstream showed higher concentrations compared to the reservoirs. There was also an increase in Hg concentrations along the river flow, when comparing only the reservoirs. Approximately 53% of the reservoir fish were above the 500 μg kg-1 w.w. limit recommended by the WHO, while 89% downstream exceeded this limit. Non-predatory fish showed no amplification trend, being similar in the sampled environments. The second article presents an analysis of total mercury (THg) in sediments and soil from the four hydroelectric reservoirs on the Teles Pires River. Sediments from the hydroelectric reservoirs showed higher THg concentrations compared to their downstream directly. We also observed that total THg concentrations in sediments increased following the river flow. The lateral soils of the hydroelectric reservoirs increased following the flow of the reservoirs, from the Sinop reservoir to the Teles Pires reservoir, decreasing at the last sampling point (São Manoel reservoir). There is a positive trend between THg concentrations in soil and sediment, suggesting possible Hg transfer during reservoir filling.

The thesis aims to analyze the process of Good Living in urban riverside communities in the state of Mato Grosso, Brazil, in light of the concepts of traditional knowledge and local ecological knowledge. These riverside communities are located in areas that have undergone the urbanization process in Brazilian cities and experience conflicts and contradictions inherent to this process. The problem presented is: What are the main factors that interfere in Good Living among riverside communities located in urban areas in the state of Mato Grosso? How does the dialogue between the concepts of traditional knowledge, local ecological knowledge and Good Living occur? The research is based on a qualitative, descriptive, documentary and bibliographical approach supported by a systematic literature review, in the Association of Artisans of the Community of São Gonçalo Beira Rio, Cuiabá and in the Association of Professional Fishermen of Cáceres, Mato Grosso, Brazil. The research methods used were bibliometrics, field research with the application of a socioeconomic and environmental questionnaire, and semi-structured interviews with the leaders of the associations, followed by an in-depth interview with the leaders of the associations. The qualitative data were analyzed based on the application of the Good Living indicator matrix (Alcântara; Sampaio, 2019, 2020) based on content analysis by Bardin (2016). The results indicate that it is necessary to improve and implement public policies aligned with the Sustainable Development Goals (SDGs) and that the context investigated lacks bold and transformative measures so that the associations in the communities become sustainable, guaranteeing rights, dignity, and Good Living to their members.

The Cerrado (the Brazilian savanna) and Pantanal biomes have been undergoing intense anthropogenic and natural disturbances, leading to significant degradation. Climate change threatens the biodiversity of these biomes, as well as critical human activities necessary for human subsistence, such as agriculture and livestock farming. However, these very activities have also contributed to climate change. Deforestation and wildfires, whether legal or illegal, carried out as tools for management and opening new areas for production, contribute to the emission of greenhouse gases (GHGs). Livestock farming is a significant emitter of GHGs globally, contributing substantially to climate change. In this context, restoration actions in the Cerrado and Pantanal, as well as the adoption of regenerative production systems, such as silvopastoral systems, which promote food security, increased productivity, income, and carbon sequestration, are urgent. Due to the acceleration of climate change, it is crucial to understand how plants respond to biotic stresses, especially concerning extreme weather events such as flooding. Flooding acts as an environmental filter that limits the establishment of trees in floodable savannas. Regarding production, the restriction of land use imposed by temporary flooding means that production is limited to livestock farming in some of these temporarily flooded areas. For this reason, it is necessary to select tree species with potential for use in ecological restoration and production in temporarily flooded soils. In this sense, Dipteryx alata (baru or cumbaru) is a tree species that deserves further study. Although it is typically a tree of dry soils, we have observed the occurrence of adult individuals in floodable pastures. The baru has a wide distribution across the national territory, as well as in Peru and Bolivia. It is a species of relevance to the bioeconomy of the Pantanal and Cerrado, serving as a supplementary source of income for many families who commercially harvest the baru nuts in an extractive manner. The tree shows promise for use in silvopastoral systems. Although it is a species typical of dry soils, it also has potential for use in restoration activities and production in temporarily flooded areas. In this context, this thesis developed a series of studies aimed at generating knowledge to enable the use of the baru for restoration in floodable soils and for the greening of temporarily flooded and non-flooded pastures, facilitating the formation of silvopastoral systems. This thesis is presented in four chapters, involving field and nursery studies. Studies were conducted on the initial silviculture of the baru in floodable soils (Chapter 1), simulation of different flooding levels in tanks (Chapter 2), development of a methodology for selecting matrices (Chapter 3), morphometric studies of isolated trees in floodable, non-floodable pastures, and in homogeneous stands (Chapter 4), as well as selection of matrices with desirable characteristics for silvopastoral systems. Therefore, the thesis adopts a broad, multi-disciplinary, and interdisciplinary approach. The results are applicable to ecosystem restoration and production activities, with a focus on silvopastoral production.

Habitat loss, fragmentation, and degradation are among the main threats to global biodiversity, including amphibians. These processes reduce both the amount and connectivity of habitat across landscapes, affecting species diversity and ecosystem services. Here, we examine the responses of anuran assemblages to forest loss and fragmentation in the state of Rondônia, southeastern Brazilian Amazonia. This dissertation is structured into a General Introduction and three articles presenting key results and their implications for amphibian conservation and distribution in the Amazon.
We sampled anurans using active visual and acoustic searches at 33 forest sites in eastern Rondônia. At all sites, anurans were surveyed over three consecutive days. The first article, titled “Contributions on anurans from the southern Brazilian Amazon: Species richness, abundance, and distribution,” provides an overview of anuran assemblages in the inventoried forest areas. Additionally, data from the literature were compiled for the Jaru Biological Reserve and its buffer zone. We recorded 64 species, 28 genera, and 13 families. Regarding distribution, nearly 80% of the species were associated with the Amazon and adjacent regions, reinforcing the high rate of endemism in the biome. Furthermore, 10.9% of the species have not been assessed by the IUCN and 7.8% not by ICMBio, raising concerns—especially considering the intense fragmentation in the region. The second article, titled “Taxonomic patterns of amphibians in southeastern Amazonia are driven by habitat loss and water availability,” investigates the taxonomic responses of anurans to environmental predictors at both patch and landscape scales. We found that species richness and composition were driven by the amount of remaining habitat in the landscape, while the availability and diversity of water bodies were the main determinants of species abundance. Landscapes with greater forest cover retained higher species richness and more heterogeneous assemblages, highlighting the negative impact of habitat loss. The third article, titled “Forest cover and availability of aquatic habitats as drivers of functional diversity in anurans from fragmented Amazonian landscapes,” analyzed how functional diversity responds to site- and landscape-level metrics. Results showed a strong effect of forest cover on functional richness and Rao’s quadratic entropy (RaoQ), indicating that well-preserved landscapes retain unique functional traits and a greater differentiation among species' ecosystem roles. Moreover, functional traits related to reproduction and dispersal capacity (e.g., body size) were associated with forest cover and the availability of ponds and streams in the landscape.Therefore, the conservation of anurans in both taxonomic and functional dimensions in this region urgently depends on halting deforestation and enhancing forest cover through ecological corridors. Additionally, water bodies should be considered conservation priorities at the landscape level to strengthen efforts to protect species.

This research, which is part of the Environmental Sciences, analyzes how traditional communities can adapt to health crises, especially focusing on the ethnobotanical knowledge of the Quilombola da Bocaina Community in Porto Estrela - Mato Grosso. It is demonstrated how this knowledge can be an additional strategy of care during the Covid-19 pandemic. The central idea is that traditional knowledge, deeply linked to the territory and transmitted from generation to generation, are importante resources, especially when access to conventional health services is limited. Faced with the health emergency and the absence of protocols, at the time, specific to treat the disease, these communities anchored the hitherto unknown care practices guided by their own traditional knowledge of curing diseases, used effectively medicinal plants to relieve symptoms such as fever, cough and flu. This study that combines different areas of knowledge and has a qualitative approach, revealed a great understanding of the population about local plants and species, highlighting the melon-de-são-caetano (Momordica charantia L.) and saffron (Curcuma longa L.). The plants most mentioned in this context are those used mainly in the form of teas and syrups. They contain compounds such as curcumin and quercetin, which have anti-inflammatory and antiviral properties, proven by scientific studies, which reinforces the traditional use of these plants. Generally, those who know these natural remedies are the elderly with lower education and income, which shows that these practices are affordable and low cost. However, the research points out two major obstacles to the maintenance of this knowledge: first, the loss of habits of use of plants and the disinterest of younger generations, driven by cultural interactions that resignify knowledge and the lack of organized records; according to the land conflicts with farmers and miners, which hinder access to plants and territory of these communities, which is fundamental for their culture and way of life. The conclusion of the study is that the ethnobotanical knowledge of quilombolas is an important care system for both health and cultural preservation. To make better use of this potential, it is recommended to promote a greater dialogue between the communities and institutions involved, the guarantee of the territorial rights of the communities, as well as the documentation and valorization of traditional knowledge are important points. Integrating these practices into primary health care, following models such as RENISUS, is a promising strategy to strengthen local culture and consequently the practices in SUS and promote more justice in access to care. In addition, the research highlights the need for more pharmacological studies to prove the safety and efficacy of the mentioned species, ensuring a solid scientific basis for their future use. Thus, the study fills a gap in the academic area by offering an integrated view on the role of these practices in times of health crisis and their relationship with public policies, highlighting the importance and originality of the context of Quilombolas Communities of Bocaina in Porto Estrela-Mato Grosso.
