  • Mostrar Abstract
  • The growth of world population has led to the expansion of agricultural areas to produce food that meet world demand, making it necessary to increase productivity and maintain sustainability in these areas. In this work was evaluated the effect of different Land Use and Land Cover (LULC) types, namely native forest, pasture, rice and soybean crops on the spatial variability of soil fertility and texture. Descriptive statistical analysis take base on pH, H+Al, Al, Ca, Mg, P, K, Cu, Fe, Mn, Zn, V, m, organic matter, clay, silt and sand values from soil samples about the different LULC. To verify the normality of the data, the Shapiro-Wilk test at 5% significance was performed, outlier analysis using boxplot graphics, principal component analysis and cluster analysis, using R software. In addition, the data were submitted to geostatistical analysis to verify the degree of spatial dependence of the variables through semivariograms, for interpolated kriging maps generated in the GS+ software. It was verified that the forest area has less fertility and greater acidity, whereas crop areas presented the opposite result. Except for silt, all variables were well represented in the factor map, in relation to PCA values the variability can be explained mainly by pH, V, Ca, K and Zn values inversely proportional to m, P and Sand. Through geostatistical analysis, spatial dependence ranging from moderate to strong was observed, generating reliability in the prediction of most attributes in pasture, rice and soybean areas. Through geostatistical analysis, spatial dependence ranging from moderate to strong was found, generating reliability in the prediction of most attributes in pasture, rice and soybean areas.

  • Mostrar Abstract
  • The Amazon Forest is expanding rapidly over the Cerrado, due to environmental and climatic conditions. In order to understand the strategies, the appearance of plants in the face of climate change, characteristics were analyzed, specifically morphological, anatomical and hydraulic. Here, we aim to investigate the hydraulic functioning of transitional (Cerrado-Amazonian) plants in comparison with plants from the Amazon savannah, a goal of sense of relationship and coordination of structure/function between leaf and wood. In addition to answering the following questions: (i) Do transitional plants present attributes in the leaf and in the wood that converge to xeromorphism when compared to species from the Amazon savannah? (ii) Which delivery plans do they present that reflect a safe hydraulic system based on leaf and wood coordination, which enable the indication for forest restoration? The botanical material was processed according to standard plant anatomy techniques. Subsequently, analyzes were performed under an optical microscope to guide the morphoanatomical attributes. The attributes that they grouped as species of SA and one of the transitional plants are related to less water loss through leaves and greater safety in water transport, for example, greater wood density for this group of species. In contrast, transitional plants reflect more transpiration on the leaves. Based on our morphoanatomical study, we provide evidence that confirms a promoter species for forest restoration, only Enterolobium schomburgkii among the five transitional plants indicated by Arguelho (2021) due to the clear presence of attributes that converge to xeromorphism.

  • Mostrar Abstract
  • The advance of agribusiness on native vegetation has promoted an increasing isolation of wild animal populations in vegetation islands, with limited food supply. Thus, this work aimed to estimate the number of cattle slaughtered by jaguars (Panthera onca and Puma concolor) during one year in a cattle-producing municipality in southern Brazilian Amazon (Alta Floresta –MT). The owners or those responsible for the properties were basically asked how many heads of cattle were on the property and how many heads of cattle were lost to jaguars in 2020. Data from a total of 409 cattle farms were analyzed. Of this total, there were reports of predation by jaguars in 81 of the properties (19.8%). When extrapolating the data for the entire municipality, considering the size of the herd, an average of 970 animals killed per jaguar is obtained annually. The total number of cattle from the interviewed properties was 261,888 heads, equivalent to 34.21% of the entire herd in the municipality. Of this total, records of 332 cattle slaughtered by jaguars were obtained, representing a mortality rate of 0.12% over the herd. The landscape connectivity analysis showed that the highest connectivity rate was a thousand meters (m) away, which represented about 13.87% (17,848) of the connections. The results of the work showed that: i) despite the low lethality of one bovine preyed on every thousand heads, cattle raisers resent and justify their dislike for felines for the monetary damage caused by them; ii) The mobility of cats between forest fragments; iii) The decline in the population of cats in the municipality; iv) The absence of anti-predation techniques applied by ranchers; v) The municipality has potential for the exploration of feline sighting tourism.

  • Mostrar Abstract
  • The Amazon biome has a significant biological and socio-environmental value for the world, harboring a great diversity of species of flora, fauna and traditional knowledge of local communities. of the preservation and conservation of the environment. Entering Environmental Education in this scenario, awareness, solidarity, equality and respect for human rights must be stimulated, using democratic strategies and interaction between cultures. The problem of the lack of accessibility in ecological trails for all people, including those with disabilities (PwD), motivated us to formulate the present work, which aimed to build an interpretive ecological trail in a conservation area in the South of the Amazon, as instrument of direct contact with nature, ensuring accessibility even for people with disabilities, whether physical, mental, intellectual or sensory. The trail was opened in an area of 500 hectares of native Amazon forest, located in the experimental area of the Executive Commission of the Cacaueira Crop Plan (CEPLAC) in the municipality of Alta Floresta, in the south of the Mato Grosso Amazon. The trail followed the ICMBio trail planning and fundamentals, classifying it as “Class 5 trail (high intervention), with adaptations along the way, aiming at accessibility and social inclusion, in addition to moments of interpretation on the trail, with the sharpening of the five senses. For data collection, we used questionnaires as a research instrument. We carried out 11 visits, serving 107 volunteers, 81 people without disabilities (76%) and 26 people with disabilities (PwDs) (24%), which cover: Visual (blind and low vision); Auditory (deaf); Physical (wheelchair user and low mobility); Intellectual and Autistic Spectrum Disorder (ASD). Bringing the focus to the main questions, in the questionnaires applied before the visit, when asked if they knew the forest in our region, 28% said they knew it reasonably, 23% said they knew it well and 24% knew it very well. And, about 40% of the visitors said they had reasonable knowledge about the plants and animals of the region and 28% said they had a good knowledge about the fauna and flora. And for the questionnaires applied after the visit, about 68% of the volunteers said that the connection with nature through the trail was very good and that it served as an efficient tool and regarding their experience about accessibility and inclusion when walking on the trail, 13% of the 26 people with disabilities (PwDs) said that the experience was good. We found acceptable visitor approval by analyzing the questions asked to each of them. Therefore, the construction of the trail proved to be an efficient instrument of direct contact with nature, bringing the focus of knowledge of the Amazon forest, in addition to bringing to light the opinion of PwDs who, for a long time, were excluded from experiences inside a forest. . Therefore, we believe that our work served as a new educational practice under a pedagogical bias of inclusion and accessibility, serving as a basis for future studies with trails of this model, this being a pioneering study in the region.

  • Mostrar Abstract
  • The species Apeiba tibourbou (Aubl.) belongs to the Malvaceae family, is popularly known as monkey comb and balsa wood, and is widely used in folk medicine. Individuals belonging to the Malvaceae family have in their secondary metabolism a variety of chemical compounds that act in the defense mechanism against herbivory such as alkaloids, tannins and saponins. Understanding the physical characteristics and chemical compounds present in plants with insecticidal properties has been important for the development of new management techniques and new phytosanitary products with low environmental impact. In bibliographic research, there was a scarcity of data about the species Apeiba tibourbou, and its chemical and anatomical composition. The present work describes anatomical, histochemical and phytochemical characteristics present in the leaves of Apeiba tibourbou, and evaluates its insecticidal potential in the control of Aphis craccivora Koch (Hemiptera: Aphididae) and Atta sexdens L. (Hymenoptera: Formicidae). The phytochemical and histochemical analyzes and the anatomical description allowed the determination of the presence of starches, total lipids, phenolic compounds, alkaloids, mucilages, terpenoids and sesquiterpene lactones, calcium oxalates and trichomes. To evaluate the insecticidal potential of Apeiba tibourbou extract in adult individuals of Aphis craccivora, aqueous and hydroalcoholic extracts of leaves were prepared and subsequently applied at concentrations of: 2.5, 5.0, 7.5 and 10%. Survival assessment was performed at 24, 48, 72, 96 and 120 hours. There was a significant decrease in the survival rate of individuals, and the hydroalcoholic extract obtained better results than the aqueous extract. In the bioassays with workers of Atta sexdens, hydroalcoholic extracts were prepared from the bark and leaves of Apeiba tibourbou. The workers separated from the colony were placed in glass flasks, where the topical application of the extract was carried out, each repetition received a pad containing distilled water and an artificial diet cube based on agar and extract-free dextrose. Survival assessments were performed every 24 hours for a period of 15 days. There was a gradual decrease in the survival rate with increasing exposure time to hydroalcoholic extracts of bark and leaves of Apeiba tibourbou, showing to be a promising species for the control of Atta sexdens. Thus, the species Apeiba tibourbou has insecticidal potential in the control of Aphis craccivora and Atta sexdens in the laboratory.

  • Orientador : ANA APARECIDA BANDINI ROSSI
  • Data: 28/02/2022


  • Mostrar Abstract
  • Manihot esculenta Crantz belongs to the Euphorbiaceae family, popularly known as cassava or manioc. The cultivation of cassava is largely carried out by family farmers. The present study aimed to carry out a survey and phenotypic and molecular characterization of the landraces cultivated by small farmers in the North of the State of Mato Grosso, Brazil. The research was carried out in three settlements, Nossa Senhora Aparecida (NSA), Júlio Firmino Domingues (JFD) in the municipality of Alta Floresta and the São Pedro settlement (ASP) in the municipality of Paranaíta. The survey and phenotypic characterization were carried out during visits to the farmers' plantations in the three settlements. The data collected in the field were tabulated in an Excel spreadsheet, and the frequency of cultivation and the frequency of the phenotypic classes of each descriptor were calculated. To evaluate the genetic diversity, leaf samples of each landrace were collected for DNA extraction. A total of 33 properties were visited, 76 cassava landraces were surveyed and characterized, identifying 22 landraces with different names. The “cacau” cassava showed high frequency, cultivated in 69.7% of the properties, being the dominant landrace in the three settlements. Morphological characterization using 13 qualitative descriptors revealed a total of 44 phenotypic classes, evidencing genetic variability among the landraces. For molecular characterization, the 15 ISSR primers amplified 223 fragments, revealing 95% of polymorphism. Genetic dissimilarity values ranged between 0.091 and 0.618. The groupings by the UPGMA method formed 9 distinct groups, the group GI was the most representative (44.47%), the GVII, GVIII and GIX groups allocated only one landrace each, respectively the individuals NSA1 (“copinha” cassava), NSA20 (“amarela” cassava) and JFD25 (“cacao” cassava). The Nei (*H) and Shannon (*I) diversity indices demonstrated the existence of genetic variability within the settlements and AMOVA indicated that the greatest genetic diversity is present within the settlements (76%). The analysis of the population structure using Structure formed two groups, according to the value of ΔK, allocating the ethnovarities in accordance with the study regions. Phenotypic and molecular characterization revealed that there is genetic variability among individuals of M. esculenta. This diversity can be used in the construction of active germplasm collections and in future breeding programs.

  • Mostrar Abstract
  • Soybean stands out among the legumes produced due to its high nutritional value and its use in various sectors of the agroindustry, but in recent years, due to the high demand of the productive sector and the growth of grain consumption, it has been necessary to integrate new management techniques in order to increase crop productivity. Thus, seeking alternatives for sustainable management in agriculture, the present study aimed to analyze the ability of Trichoderma atroviride, applied at different vegetative stages, in its action as a growth promoter and in plant protection in soybean, associated with boron doses. The experiment was carried out in a completely randomized block design, in a 4 x 5 factorial scheme, with applications of Trichoderma atroviride carried out at four different times (SEM, V5, R1 and R5) and five doses of boron (0, 500, 1000 , 1500 and 2000 g ha-1). The research was conducted on the property called Fazenda Bela Vista, located in the municipality of Alta Floresta. Trichoderma was applied in a solution of 2 x 107 conidia/mL via leaf on soybean. In the first chapter the effect of the treatments on the vegetative and productive characteristics of the soybean crop was addressed and in the second chapter the physiological response of the crop was evaluated. With the use of the microorganism associated with the micronutrient, it was not possible to significantly observe the growth promoting action and increase in soybean productivity, but it was observed the action as a plant protector, minimizing the different stressful conditions, in which, it was verified if the performance physiology of plants through the increment of elements that are essential for the growth and development of the culture.

  • Mostrar Abstract
  • The soils of southern Amazonia undergo modifications for the implementation of agriculture, livestock and forestry, and in general, these are poorly managed. And as these are naturally acidic and deficient in nutrients, due to accelerated weathering and the processes of soil formation, continue to affect their characteristics over the years, with all this, the quality of the soil is constantly altered. To know which managements were or are being less harmful to soils, we can study their attributes. In this way, the present work aimed to evaluate the quality of the soil through its chemical and physical characteristics, in addition to carrying out the study of the fractionation of phosphorus together with the microbial activity of the soil, in different uses that consisted of pasture areas, natural regeneration, tillage, forestry with teak production and forest fragment, in the south of the Amazon. We evaluate the physical attributes through porosity, density and penetration resistance; biological indicators by soil basal respiration, microbial biomass carbon, metabolic quotient and acid phosphatase; the chemicals were evaluated by the analysis of soil acidity, nutrient saturation, aluminum and hydrogen contents, organic matter, exchangeable calcium, exchangeable magnesium, exchangeable potassium and phosphorus. Due to the importance of phosphorus for crops and its deficiency in this region, its fractionation in the soil was evaluated. Most characteristics are influenced by management, where certain practices benefit the chemical characteristics of the soil, while others harm certain characteristics, mainly physical and microbiological characteristics.

  • Data: 30/03/2022


  • Mostrar Abstract
  • The standardization of biological information dispersed in biodiversity platforms is essential to condense complete and reliable information on species composition and physical characteristics of the environment. Thus, our objective was to build a database with plant species occurring in the Cerrado-Amazon transition (CAT), containing the collection records and their geographic coordinates. Based on this database, called ‘NeoTropTrans’, we seek to answer the following questions: 1) What are the most representative species, genera and families in the CAT? 2) What are the best-sampled regions and vegetation types and those with the greatest gaps in collections? 3) How are species occurrence records distributed along the different land use and land cover categories in the CAT? The occurrence records of plant species (angiosperms, gymnosperms and ferns) were obtained from the speciesLink, GBIF and REFLORA online platforms. We compiled 51,886 occurrence records for the Cerrado-Amazon transition, of which 50,523 of angiosperms, 14 of gymnosperms and 1,349 of ferns/lycophytes. Among these records, 28,536 were for trees, 19,665 for shrubs, 9,970 for herbs, 6,619 for vines (woody and non-woody), 5,203 for subshrubs, 618 for palms, 50 for bamboos and 24 for succulents. The occurrence records were distributed in 209 families, 1,384 genera and 5,889 species. The families with the highest species richness were Fabaceae (699), Rubiaceae (317) and Poaceae (262). The genera with the highest species richness were Miconia (96), Piper (71) and Solanum (58). The families with the highest number of occurrences were Fabaceae (6,765), Rubiaceae (2,713) and Melastomataceae (2,276). The genera with the highest number of records were Miconia (1398), Protium (844) and Solanum (652). Among the most common species, Pourouma minor Benoist (214 records), Cheiloclinium cognatum (Miers) A.C.Sm. (174), Jacaranda copaia (Aubl.) D.Don (170), Myrcia splendens (Sw.) DC (160) and Siparuna guianensis Aubl. (144). We obtained 2,738 species occurring only in the Amazon and/or Cerrado, representing 46.49% of the total species present in the database. This ecotone, due to its large territorial area, provides diversified habitats, allowing the occurrence of species from adjacent biomes. With NeoTropTrans we hope to make better use of the data available on biodiversity platforms for the transition between the largest biogeographic regions of the Neotropics.

  • INFLUENCE OF SOILS AND SPACE ON THE VARIATION, DISTRIBUTION AND WEALTH OF WOODY SPECIES IN ROCKY OUTLOOK IN THE CERRADO-AMAZON TRANSITION
  • Orientador : GUSTAVO CAIONE
  • Data: 31/05/2022


  • Mostrar Abstract
  • Between the Amazonian DMF and the Cerrado DMF, there is a transition zone, marked by the phytophysiognomic diversity and ecosystem complexity resulting from the floristic interactions of the different Domains. This diversity can, on a broader scale, be explained by climatic factors, such as temperature, precipitation, relief, etc.; however, there is variation in the diversity, composition and structure of vegetation under the same climatic conditions, which can be explained by the interaction of edaphic, hydrological, geomorphological and climatic factors.

    Our objective is to investigate the influence of soil attributes on the distribution and species richness in a rocky outcrop area; for this, we collected soil samples from 25 subplots installed in RPPN Cristalino and performed analyzes of 23 physical-chemical soil attributes. For the statistical analysis we used a matrix of soil, richness, distribution and a spatial matrix. To verify the variation of soil attributes, we performed a PCA; to verify the affinity between these attributes, we performed a “Hierarchical Grouping of Variables” and a correlation matrix; to verify the influence of soil on distribution and richness, we performed correlation analysis, and used Generalized Linear Models (GLM); in addition, we performed a partitioning analysis of the variation and response curve for the variables selected by the model. Results: the variation of soil attributes was greater than expected by chance; the first axis of explained 30.7% of the variation, with N, Ct, Mn, Ca, C.ORG., M.O., Mg, Silt, pH H2O being the most important variables. The second axis explained 20.57% of the variation, with Zn, Cu, P. res, the most important variables. The variables were grouped as expected, elements related to organic matter, texture and acidity, with some exceptions such as Mn, which was grouped with Ca and Mg, probably because it is an element of the source rock. The elements Fe and Mn were significant to explain species distribution, and P. res influenced species richness more than expected by chance. In the variation partitioning, the environment and the environment + space were the ones that contributed the most to the model, the space was just not important to explain the variation. From the selected variables, we performed the response curves to verify the affinity of the species to the attributes, the results are very variable between the species. Even in a small area, there was variation in soil attributes, the species that present a greater range of tolerance may be benefiting; source rock elements such as Mn may be filtering the occurrence or abundance of species.

    Genetic Diversity and Cytogenotoxicity of Copaifera langsdorffii Desf. (Fabaceae) native from the Amazon Mato-Grossense

  • Orientador : ANA APARECIDA BANDINI ROSSI
  • Data: 20/01/2021


  • Mostrar Abstract
  • The Amazon Forest is the largest tropical forest in the world, with 60% belonging to the Brazilian territory, one third of the forest is located in the state of Mato Grosso. It is estimated that about 20% of all the planet's biodiversity is found in the Amazon. Among the species present in the Amazon, we highlight the Copaifera langsdorffii Desf., exploited mainly for the extraction of its oil-resin and wood, and also to be used in folk medicine in the treatment of various diseases. Inadequate management of C. langsdorffii, as well as forest fragmentation, can cause a decrease in the number of individuals in the populations, which in the long run can cause the loss of genetic variability. This study aimed to perform the molecular characterization of 27 individuals of C. langsdorffii collected in the Amazon located in Mato Grosso state, Brazil, and to evaluate the toxic, cytotoxic and genotoxic potential of the species. For evaluation of genetic diversity, 12 ISSR primers were used, which amplified 106 fragments, 98.11% of which were polymorphic. The content of polymorphic information (PIC) of each primer varied between 0.45 and 0.81. The average dissimilarity found was 0.49. The greatest genetic variability is found within the groups and not between them. The percentage of polymorphism, values of genetic dissimilarity and indexes of genetic diversity, indicate that there is high genetic variability among C. langsdorffii individuals, suggesting that ISSR primers are efficient in detecting polymorphism in this species, and that the population has the potential to compose  conservation programs and the ability to integrate germplasm banks. The assessment of toxic, cytotoxic and genotoxic potential was performed using the Allium cepa test. The aqueous extracts (infused and decocted) obtained from the stem bark and leaves of C. langsdorffii were evaluated, with five different concentrations and two controls, with distilled water (negative control) and glyphosate at 1% (positive control). The growth of the root system (CSR), the mitotic index (MI), and the frequency of chromosomal changes and / or abnormalities in the phases of cell division were evaluated. The greatest reductions in CSR were found in decocted extracts (stem bark and leaves). For the stem bark, both extracts at concentration of 0.032 mg mL -1 showed lower MI. The concentrations 0.002 mg mL-1 of the infused bark extract and 0.004 mg mL-1 of the decocted leaf extract showed 4.19 and 3.55% of cell aberrations respectively, followed by the positive leaf control with 5.71%. The results showed the toxic, cytotoxic and genotoxic potential of the aqueous extracts of C. langsdorffii on the test organism.

  • Mostrar Abstract
  • Peanuts (Arachis hypogaea L.) belong to the Fabaceae family, the same as other crops known as beans, soybeans, lentils and peas. Its genus, Arachis, houses more than 80 species, some with economic importance, for human consumption, ornamentation or forage. This culture is very important for human food, very present in family farming, being one of the most cultivated oilseeds in the world. The objective of the study was to carry out a survey of the traditional varieties of A. hypogaea cultivated by farmers in the municipality of Alta Floresta, Mato Grosso, and to evaluate genetic diversity through phenological attributes and morpho-agronomic descriptors. Eight traditional peanut varieties collected from rural communities in the interior of the municipality were evaluated. The experiment was carried out in the same municipality, and evaluated the genetic diversity of the varieties through vegetative, fruit and seed descriptors, in addition to vegetative and reproductive phenology. The data obtained in the interviews with the interviewed producers, as well as the phenological attributes and qualitative morpho-agronomic descriptors were submitted to descriptive statistics. The data from the quantitative morphoagonomic descriptors were subjected to analysis of variance and comparison of means. Ten producers were interviewed, all male, aged between 50 and 84 years old, 20% of them retired. They have between 2 and 50 years of experience with the crop, and 80% of them stated that their seeds come from Mato Grosso. Its seeds are stored with pods, in nylon bags, burlap, water tanks and old refrigerators, or in PET bottles, without pods. The monoculture system predominates, only 10% carry out intercropping. All respondents cultivate for their own consumption, and 60% market grains and derivatives. All quantitative variables showed a significant difference at the level of 1% probability by the Tukey test. The cluster analysis by the Tocher method resulted in the formation of three groups, with group II covering 62.5% of the accessions, followed by group I with 25%, agreeing with the groupings formed from the dendogram generated by the UPGMA method, and the result of the graphic dispersion of varieties through canonical variables. The analysis of the canonical variables of the 14 quantitative characters showed that the first two variables explained 97.49% of the total variation. Plant height, mass of 100 grains, chlorophyll index and number of pods presented a greater relative contribution to genetic divergence. In the phenological evaluations it was verified that the accessions UNEMAT 024, 026 and 027 germinated first, 4 days after sowing. The appearance of flower buds in these varieties was also earlier, at 24 days. The accessions UNEMAT 021 and 022 showed the lowest phenological cycle, of 100 days, showing good adaptation to the environmental conditions of the region. In addition to helping producers to obtain better yields by choosing the most productive varieties, the present study also showed promising genetic materials that can be used in new breeding programs in the northern region of Mato Grosso.

  • Abstract: In this dissertation, an evolution of environmental legislation was addressed, as well as a case study with the subsumption of the law in concrete projects to make forest restoration feasible, showing the efficiency of the methods applied by an environmental public policy. A traditional bibliographic research method was used, highlighting the multidisciplinary nature of the environmental issue since it is necessary to know several scientific areas. In the first chapter, a bibliographic survey of the evolution of the legislation regarding the protection of the environment was carried out; analysis of the importance of the rural environmental registry (CAR) as a method of controlling deforestation; and studying the terminology conflict between restoration, restoration, recovery, and restoration of native vegetation. In the second chapter, legal issues were analyzed in order to apply the theoretical perspectives of law in the concrete cases proposed by the SEMA (State Secretariat for the Environment) of Mato Grosso, and the project Olhos D'água da Amazônia was implemented for the documentary research. in the municipality of Alta Floresta (MT), in order to reduce deforestation and increase forest restoration rates, in order to recover APPs (permanent preservation areas). Also selected as a sample was a study carried out by ICV (Instituto Centro e Vida) in the Municipalities of Alta Floresta, Carlinda, and Paranaíta in the State of Mato Grosso, comparing the gain and loss of forest during the years 2008 to 2019. With the study it was it is possible to concretely make the general objective of the work viable, that is, demonstrate that an environmental public policy will be efficient if there is political will from the government, financial investment, involvement of specialists, and participation of society in the process of raising awareness of the importance of biodiversity conservation, as well as alignment of a sustainable economic development policy

  • Mostrar Abstract
  • Ants are organisms found in the most varied terrestrial ecosystems with the exception of the poles, playing a multitude of ecological roles ranging from potential dispersers to predators or scavengers performing ecosystem services, which bring positive impacts to the environment. They are currently considered the largest group of social insects with more than 13,000 named species and an estimated biomass of more than 10,000 trillion individuals, which represents most of the animal biomass in tropical forests. Given the characteristics that this group of insects present: relatively developed taxonomy, easy sampling, high values of wealth and abundance in the varied ecosystems of the planet, they are characterized as bioindicator organisms. Thus, this research aimed to get to know the myrmecofauna in different plant formations in the municipality of Alta Floresta-MT, and to understand how these organisms are structured in a native environment in relation to vertical stratification, where sampling was carried out in two strata (arboreal and epigenic) ) in a remnant of native vegetation in the municipality. In addition, restoration strategies used on a property in the municipality of Alta Floresta-MT were evaluated by analyzing the composition (abundance and number of species) of the arboreal and epigenic assemblies of ants. For the sampling of ants, transects of 120 meters in length were established, both with five sampling points equidistant 20 meters from each other and in both sampling points a trap in the ground (pitfall of soil) and a trap in the vegetation (pitfall tree) were installed. ). The collected ants were placed in collecting pots containing 70% alcohol and taken to the State University of Mato Grosso where they were separated from the other collected arthropods, identified at the gender level and reviewed by a specialist. Ants showed values for both abundance and number of higher species in the epigenic stratum in relation to the arboreal stratum, the subfamily Myrmicinae being more frequent in both samples, both in the first and in the second chapter. In addition, the influence of the collection season (drought and rain) on the parameters abundance and number of species and a significant influence of nesting and turnover on the structure of beta diversity in the remaining forest was detected. In the evaluation of the restoration strategies, it was identified that the restoration areas showed diversity superior to pasture and forest fragment, in addition to forming a group distinct from the forest fragment in relation to the similarity in the composition of the ant assemblages, being more similar to the landscape of ants pasture.

  • Mostrar Abstract
  • Few sources of information exist about secondary vegetation in Brazil, which consists of vegetation originating from areas that were deforested in previous years and later abandoned by use if they regenerated and / or were recomposed by human action. In Mato Grosso, many areas of environmental liabilities have been restored in recent years, due to legal requirements and / or abandonment of use. The objective of the present work, divided into two chapters, was to map and validate the forest restoration (RF) that occurred in the period from 2008 to 2019 and to analyze its spatial distribution over the network of rural properties, Permanent Preservation Areas (APPs), Legal Reserves (RLs) and properties benefited by projects financed by the Amazon Fund in three municipalities in northern Mato Grosso. The study area comprised the municipalities of Alta Floresta, Carlinda and Paranaíta, which together totaled a total area of 1,616,537 ha. The mapping was performed through visual interpretation in freely accessible orbital images. The vectorization scale was 1: 25,000. The mapping validation was carried out through systematic sampling from the polygons that were located within a maximum radius of 50 meters from the axis of the municipal road network. A total of 567 sample areas were selected. All field work was carried out by land using a motor vehicle. To measure the accuracy of the mapping, the Global Accuracy, Conditional Kappa and Tau indexes were used. Net deforestation was calculated by subtracting the RF area from the PRODES / INPE deforestation area. For the spatial distribution analysis, digital cartographic bases of the property limits provided by ICV (2018), APP limits, property limits benefited by the Olhos D’Água da Amazônia (PRODAM) and Nascentes do Buriti projects were used. Rural properties were subdivided into five classes according to the number of fiscal modules (MF) being: Up to 1 MF; from 1 to 2 MF; from 2 to 4 MF; from 4 to 15 MF and above 15 MF. The size of the MF in the three municipalities according to INCRA is 100 hectares. The amount of RF for the period and for the study area was 14,605.1 ha and 7,302 polygons. The accuracy indices showed values of 95.5%, 91.1% and 90.9% respectively, with performance classified as excellent. The average height of vegetation in the sample areas was 7.11 meters. Alta Floresta had 

    the highest number of polygons, 4,449, and the largest area, 9,975.4 ha of RF. Carlinda had the best net deforestation balance - 103.7 ha. Paranaíta had lesser performance both in the quantity of RF and in the net deforestation balance. The rural property class above 15 MF was the one that stood out the most, with the highest number of polygons, the largest area and the highest percentage of properties with an incidence of RF. The RF focused more heavily on areas of APP compared to RL. The environmental liability in APP was 22,328.69 ha in the entire study area until the year 2019. The incidence of RF on the areas of APPD between the years 2016 to 2019 was only 7.9%. The PRODAM project was able to achieve its initially proposed goal of recomposing 1,200 ha of forest, while the Nascentes do Buriti project has so far reached 14.3% of the initially proposed goal. Despite efforts, the two projects contributed 9.5% of all RF in the entire study area. The entire database used in the analysis of this work is openly available through the link: https://arcg.is/0qKjCi.

  • Mostrar Abstract
  • Corn is the most cultivated cereal in the world and has great economic relevance, since it is used as a raw material for multiple sectors. Thus, proper crop management is essential especially when aiming higher yields and grains with better quality. In this context, Zn stands out since its deficiency is one of the most limiting factors for the development of culture. Given the above, the objective of this study was to evaluate the effect of seed treatment with doses of Zn in the form of sulfate and in the form of nanoparticles on the germination and seedling development, the effect of doses of Zn in nutrient solution and foliar fertilization with doses and sources of Zn in corn. The first experiment was in a 4x2 factorial scheme with doses (0, 20, 40, 80 g kg-1 of seed) and sources of Zn (ZnSO4 and ZnO 60 nm) and the second experiment with sources of Zn (ZnSO4, ZnO 60 nm and ZnO 40 nm). For both experiments, the DBC with four replications was applied and the seedling and root length, stem diameter, fresh and dry mass, root volume, IVG and germination rate were evaluated. The field experiment was carried out in the city of Alta Floresta - MT in a RED YELLOW OXISOL. DBC was used in a 4x2 factorial scheme with doses (0, 250, 500 and 1000 g ha-1) and sources (ZnSO4 and ZnO 40 nm) with four replications and foliar application in stage R1. At the end of the experiment, productivity, ear diameter, mass of 100 grains, number of rows per ear and Zn content in the grains were evaluated. The hydroponics experiment was carried out in a greenhouse and the DBC was used with doses of Zn (0, 1, 2, 4 and 8 mL L-1). At the end of the experiment, the shoot and root length, stem diameter, root volume, shoot dry mass, protein and micronutrient content were evaluated. The application of nanometric sources in the treatment of seeds promoted greater IVG, green and dry mass, length of the aerial and root parts in relation to the sulfate source. Comparing the nanometric sources, the 40 nm source promoted a higher green mass value of the aerial part, suggesting a greater absorption of the smaller size oxide source. In the field experiment there was no significant difference in the analyzed variables. This fact suggests that the Zn content present in the soil was sufficient to meet the nutritional needs of the corn hybrid used. Regarding the Zn content in the grain, more than one application of the micronutrient is recommended during the culture cycle. It was evident in the hydroponics experiment the lowest corn development when deficient in micronutrient. The group with dose 0 showed lower values for growth variables. In addition, nutritional imbalance was observed through the greater accumulation of Fe, Mn and B due to Zn deficiency. Also, it was found that the excess of micronutrient promoted lower values of shoot dry mass, stem diameter and root volume compared to the ideal dose (1 mL L-1) due to the phytotoxic effect.

  • Mostrar Abstract
  • Livestock and soy are the main drivers of deforestation in the Brazilian Amazon. The purpose of this work was to verify the conversion of natural areas for soy planting after the Soy Moratorium, between the crop years 2009/2010 to 2017/2018. To evaluate the deforested areas, images were used via remote sensing of the Landsat satellites made available by the Global Forest Change database, with files containing 8-bit values, with a spatial resolution of one second of arc per pixel, or approximately 30 meters per pixel in the equator. The areas cultivated with soy were identified with the PCEI index (Perpendicular Crop Enhancement Index). Boxplots were built to demonstrate the variation of the variables evaluated over the time series. To check the trend of variables over the years, the Man-Kendall test was applied, followed by the Pettitt test to identify the probable point of change with the significant trend at 0.005 for the Pettitt test. All analyzes were performed with R software with the aid of the “ggplot2”, “trend”, “ManKendall” and “factoextra” packages. In the 2017/2018 crop year, soy was present in seven Amazonian states, with the exception of Amazonas and Maranhão and occupying an area of 5,237,640 hectares (ha). The states with the largest planting areas were Mato Grosso (4,453,053 ha), Pará (565,541 ha) and Rondônia (95,934 ha). The states with the largest areas of deforestation were Pará and Mato Grosso and the trend test showed that the probable year of change was 2006 for the state of Mato Grosso, which coincides with the year of implementation of the Soy Moratorium. As of 2009, 12,413,267 ha have been deforested. Of this total, 359,606 ha were converted into soybean areas. This represents only 2.90% of all deforestation in the Amazon in the period. Our results show that cattle ranching remains the main driver of deforestation in the Amazon and that the public policies that have existed so far have not been sufficient to contain deforestation.

  • Mostrar Abstract
  • Monitoring programs in the Amazon are essential to contribute to the identification of illegal deforestation and thus guide decision making by Organs responsible agencies. Thus, the objective of this work was to identify the expansion of soybean farming in disagreement with the Soy Moratorium (MS) in the Amazon biome of Mato Grosso over the years 2008 to 2019. Data from PRODES (Deforestation Calculation Program in the Amazon), ImazonGeo (Geoinformation Program on the Amazon) and the Perpendicular Vegetation Crop Enhancement Index (PCEI) were used. The Kernel Density Estimator (DK) was applied to verify the areas (polygons) of major occurrences converted from forest-soybean and the Pettitt and Mann-Kendall test were applied to identify trends throughout the time series. The results showed that during the period from August 2008 to October 2019, 1,387,288 hectares were deforested according to PRODES data and 108,411 hectares were replaced by soybeans. ImazonGeo data showed 729,204 hectares deforested and 46,182 hectares converted to soybean areas. Based on the deforestation polygons of the two PRODES and ImazonGeo databases, the DK estimator indicated that the regions with the highest occurrences at odds with the MS were in the South, Southeast and East. The municipalities with the largest areas at odds with MS were Feliz Natal with 11.,169 hectares and Tabaporã with 9,865 hectares according to PRODES data and Feliz Natal with 6,157 hectares and Nova Ubiratã with 4,786 hectares according to ImazonGeo. The results indicate that the PRODES system presented, in all cases, greater variability in the data and means statistically superior to the ImazonGeo.

  • Conflicts with white leap peccary (Tayassu pecari) and Farmers in the South of the Brazilian Amazon

  • Mostrar Abstract
  • In recent years in Brazil, invasive species in cultivation areas have been raising concern among farmers due to damage and losses in production. A study carried out in the Parque Nacional das Emas, for example, shows a daily consumption of 1.9 kg of corn by the white leap peccaries (WLP) (Tayassu pecari). However, these invasions are driven by deforestation that causes forest fragmentation, loss of habitat and reduced availability of resources, forcing fauna to explore agro-ecosystems in search of food. An example of this is the situation of the WLP. While they have disappeared from much of the country, they are still abundant and live in conflict with corn farmers in the state of Mato Grosso. Thus, this species, resilient to the impacts of forest fragmentation, is now seen as a pest specie by farmers. Due to this conflicting relationship, this work was divided into two chapters and had two main objectives. The first estimated the economic impacts caused by the WLP on corn production on a single property in the south of the Brazilian Amazon. The second assessed the dispersed functional connectivity of the WLP in an environment with an agricultural matrix, to use as a predictive model of areas to be invaded and aiming at guiding producers regarding this possibility. For the first objective, we used a property in the municipality of Alta Floresta, with 1,100 hectares of corn crops. In this property we randomized 50 collection points, all around the crop, represented by one hectare each, composed of six treatments (distances from the edge of the forest fragment), divided into five repetitions of 10 linear meters of corn, where the whole and damaged corn stalks were counted. We calculated the percentage of damaged corn stalks at each point, extracting an average loss for the points analyzed, being extrapolated to the entire crop. For the second, we used data on the presence and absence of white-lipped peccaries, acquired through visits to properties that grew corn in the 2018/19 crop year in Alta Floresta, Carlinda and Paranaíta in the state of Mato Grosso. With the ArcGis Software and orbital scenes from the CBERS-04A satellite (China-Brazil Earth-Resources Satellite), we identify forest fragments and crops to quantify connection rates through the Conefor Sensinode 2.6 plugin, through the integral connectivity index (IIC).  We found 1.25% of damaged plants throughout the property, representing a loss of R $ 34,344.75 for the owner. Crops were invaded at a rate of up to 300 meters in connection with forest fragments. Even low damage rates are not tolerated by farmers. This intolerance and persecution promoted by farmers may compromise the survival of the WLP in the agricultural frontier areas in the Amazon. One of the solutions to avoid conflicts would be for crops to be cultivated at least 300 meters away from the nearest forest fragment.

  • Mostrar Abstract
  • The demand for silvicultural knowledge aimed at native species in Brazil, in recent years, has increased significantly, mainly due to incentives for the restoration of riparian forests and the recovery of degraded areas, since the success of the implementation of reforestation programs depends on basic information about the species to be used. Since the study of environmental and edaphic limiting factors such as pH in germination and seedling development contribute to the choice of species for adverse situations in the field and consequently in implementing forest restoration. And the seedling morphological studies help in the botanical identification, contributing with the recognition of the seedling species in forest formations. However, little is known about the characteristics of native forest species due to the scarcity of studies carried out with species mainly in the Southern Amazon. Thus, the aim of this study was to evaluate the influence of pH on germination and on the development of seedlings of forest species native to the Southern Amazon. And yet, perform the morphological description of the germination process to the seedling by means of illustration of species used in forest restoration programs in the region. In the analysis of the pH influence, in the germination test with the following species: Bauhinia ungulata; Cecropia pachystachya; Chloroleucon tortum; Colubrina glandulosa; Enterolobium schomburgkii.; Guazuma ulmifolia Lam.; Samanea tubulosa; Parkia pendula; and Senna multijuga. Wetting was carried out using solutions with regulated pH: 2.0; 3.0; 4.0; 5.0; 6.0; 7.0; 8.0; 9.0; 10.0; and 11.0. And the percentage of final germination and the germination speed index were determined, as well as shoot length, radicle length, total length, and weight through seedling morphometric analysis. The germination tests were conducted in a completely randomized design, and the data analysis was performed using the Kruskal-Wallis test, followed by Dunn's post-hoc test with Bonferroni-type p-value adjustment (p <0.05). The description and morphological illustration of the germination process until seedling were carried out by monitoring the development of normal seedlings. For most of the analyzed species, there was a decrease in the values of the variables analyzed at extreme pHs, especially at pH 2 and 11. However, for all species analyzed, for a wide pH range tested, the species presented satisfactory germination rate, where they presented excellent performance at pH 5. As for the morphometric description, the characteristics observed in the three stages of seedling development, can assist as guides in the identification of species in the seedling phase in the field, as well how to help distinguish between normal and abnormal seedlings.

  • Mostrar Abstract
  • As it has one of the richest biological diversity on the planet, Brazil has a vast potential for research with vegetables that substantiate secondary metabolites, among which we can mention the species of the genus Xylopia L. Xylopia produces a variety of secondary metabolites and has been investigated as a source potential of compounds that exhibit a wide variety of biological properties. Secondary metabolites are not directly related to plant growth and development, but assume functional characteristics that allow them to respond to environmental stimuli; in the same way that possible changes in the anatomy of species can perform functions that suggest a certain adaptive degree. In this sense, this study had as main objective to investigate Xylopia species occurring in different areas in the southern Amazon of Mato Grosso, seeking to characterize and compare anatomically and histochemically six species of the genus, in addition, we investigate possible adaptive characteristics of Amazonian Xylopia in different communities vegetables from the region. To carry out the study, we used leaves of tree species of the genus Xylopia, which were subjected to the usual methodologies for anatomical and histochemical research. The research is organized in two chapters, the first deals with the description and anatomical and histochemical comparison of the species: Xylopia amazonica, X. aromatica, X.benthamii, X. frutescens, X. neglecta and X. sericea, where it was possible to verify that the species have shared anatomical characteristics, such as paracitic stomata, epidermal cells with straight walls, thin cuticle, bulky substomatic chambers and secretory channels. As well as the results referring to histochemical tests, which also revealed similarity between species, since of the ten tests performed, five reacted positively in all species. The compounds present in the species, perform ecological functions related to adaptations to the environment, such as reduced sweating, water storage, defense against herbivory and antifungal action. Despite the large number of shared characteristics, it was possible to separate them into groups, where the species X. frutescens and X. sericea are the most similar among the six. The results obtained are able to assist in taxonomic studies in the circumstance in which they suggest greater kinship between the species X. frutescens and X. sericea and X. amazonica and X. aromatica. The second chapter revealed that four anatomical attributes differ between the studied sites, namely, stomatal size, central rib bundle thickness, palisade parenchyma thickness and leaf wing thickness, thus, the mean annual precipitation and the seasonality index also influenced the variation of these tissues, except the thickness of the leaf wing. Although some attributes do not vary between sites and are not related to environmental variables, they showed a higher value for intraspecific variability, such as the thickness of the adaxial and abaxial epidermis, stomatal density and thickness of the lacunous parenchyma. This study shows that X. amazônica presents a difference in the anatomical attributes between the different sites and that these differences are closely linked to environmental factors, more especially the average annual precipitation.

  • Mostrar Abstract
  • The process of opening and transforming forest areas into planted pastures, changes the dynamics of the environment, changes the cycling and availability of nutrients, with P being one of the most affected elements. Thus, the objective was to verify the changes in the chemical attributes of the soil and in the fractions of P in Amazonian soils cultivated with unfertilized pastures and with different opening times in relation to an area of native forest. The study was carried out in a Dystrophic RED LATOSOL and a Dystrophic RED-YELLOW ARGISOL. This research deals with an observational study where 6 areas were studied and the variables were the chemical attributes of the soil and the fractions of phosphorus in two depths (00-10 and 10-20 cm). The plots consisted of pasture areas of different ages, in Nova Guarita, MT, the pasture areas of 15 and 30 years old and adjacent native forest; in Alta Floresta, MT, the pasture areas of 20 and 35 years old and adjacent native forest. Within each plot, four experimental units were separated with dimensions of 10x50 m. Within each experimental unit, ten simple random soil samples were collected in the 00-10 and 10-20 cm layers. There was an effect of the opening time of the areas on the chemical attributes and fractions of phosphorus for LVd and PVAd. The nutrient content decreased in the studied pasture areas, in both soils, with the exception of the Ca and Mg content in the 35 years old pasture area, a fact that may be associated with animal supplementation. Phosphorus fractions considered labile decreased and non-labile fractions increased in both soils in pasture areas, as the opening time increased. The advance of land use time significantly influenced the chemical attributes and forms of phosphorus in the soil in the pasture areas compared to the native forest areas.

  • Mostrar Abstract
  • Future climate changes and modifications in land use and land cover are anthropic processes of threats to global biodiversity. For the conservation and restoration processes of impacted areas to be efficient, it is necessary to investigate the effects of climate change on local plant species. Here, we aim to understand which plant species, which are being used in the recovery process of impacted areas of the Cerrado-Amazon Transition, will support future climates. To verify whether species used in forest restoration will find suitable areas in the future throughout this transition, we model, using niche-based models, their present potential distributions by projecting them into the future climate (2070). We used eight modeling algorithms, three global climate models (GCMs) and selected models based on True Skill Statistic (TSS). The post hoc chi-square test showed significant differences among the present, optimistic future and pessimistic future for 45 species of the 48 modeled species. Our results indicated 15 species as most promising for restoration in the Cerrado-Amazon Transition considering future climate change scenarios. Ensemble models showed that climate change is expected to alter the geographic distribution of all selected species (15 species) and not selected (29 species), with that, we observe how the anthropic actions in relation to the climatic changes can modify the distributions of these species, with high suitability for some and low or loss of suitability for others, modifying the landscape and possibly the traditional life of many people who live from these species in the Transition Cerrado-Amazon region.

  • Knowledge of meteorological conditions is essential for decision-making in agro-ecosystems, requiring precise information on the climate and atmospheric conditions. For that, some steps are required to be built. Data collection is the initial step for this process, however, it is subject to errors that will inevitably hinder subsequent analyzes and knowledge generation, resulting in erroneous decisions. The information needed to build knowledge is not always available or is reliable. Therefore, mechanisms for treatment, analysis and forecasts are essential in the management of agro-ecosystems, ensuring efficiency and assertiveness in decisions. The objective of this work is to describe the functioning of PAP Meteor (Preparation, Analysis and Forecast of Meteorological data), applying data provided by the National Meteorological Institute (INMET) in a surface meteorological station in the municipality of Matupá MT and Sinop MT. PAP Meteor is a system (WEB) developed with the Python programming language, subdivided into 3 modules. The pre-processing module is responsible for reading the database and returning its main information, in addition to identifying anomalies and imputing missing records. The exploratory analysis module performs a statistical summary of the data, correlation analysis in addition to exploring the data with dynamic tables and graphs. In the Matupá meteorological data, inconsistencies in temperature and precipitation were identified, in addition to 55.1% of failure in the records, in Sinop the failures add up to 28%. The system was efficient in imputing missing data on temperature, relative humidity and precipitation. In Matupá, temperatures vary between 10 and 40 ° C with annual averages of 33 ° C with a positive upward trend. Precipitation is prevalent in the months of January to April and from October to December. PAP Meteor can contribute to the knowledge generation process, contributing to greater sustainability and rationalization of resources in agro-ecosystems.

  • Mostrar Abstract
  • Lettuce is an important vegetable due to its nutritional value, but the main form of cultivation (soil) and the need for a large amount of production, makes the crop dependent on high production technology. As an alternative for sustainable management to meet the need for consumption, the present work through three experiments aimed to evaluate the capacity of microorganisms as biological agents in two cultivars of curly lettuce (Mediterranean and Solar) on the nematicidal potential of Meloidogyne spp., And also assess whether they are capable of promoting growth. The first (Mediterranean) and the second (Solaris) experiment were carried out to test the behavior of each cultivar. For this, a completely randomized design was used in a 7 x 3 factorial scheme, in which biological agents (Witness, three isolates of T. atroviride, T. viride, Bacillus subtilis and Azospirillum brasilense) were applied on the Meloidogyne incognita, M. javanica and M. enterolobii infestation. In the third experiment aiming to evaluate the capacity of growth promoters, a completely randomized design was used in the factorial scheme 2 x 6, with two cultivars (Mediterrânea and Solaris), on the action of growth promoters (Witness, Three isolates of Trichoderma atroviride, Bacillus subtilis and Azospirillum brasilense). Both experiments were conducted in a protected environment, consisting of microorganisms applied via solution to the lettuce roots. The data were submitted to analysis of variance, and the treatment averages were compared using the Scott Knott test at 5% probability with the aid of the Sisvar software. The use of microorganisms as biological agents and growth promoters has shown promise, especially the use of Bacillus subtilis and T. atroviride.

  • Data: 14/02/2020


  • Mostrar Abstract
  • Pará nut is an important forest species in the Amazon biome, and its economic exploitation is based on its timber and non-timber products, especially almonds. The northern region of Mato Grosso is mainly responsible for the production of Pará nuts in the state, and, moreover, for its edaphoclimatic conditions, has great potential for the development of homogeneous and intercropped production systems. In forest agroecosystems, especially homogeneous plantations, the occurrence of damage by pest insects is one of the main obstacles to productive success. In general, the orders Coleoptera and Blattodea (Termitoidea), are of high economic relevance since they can under certain management conditions cause deterioration of forest individuals, seedling mortality, damage to the root system, and other injuries. Thus, this work evaluated the occurrence of termites and coleobrocas in native and homogeneous systems of Pará nuts in the north of Mato Grosso. In the evaluation of coleobrocas (Subfamily Scolytinae) associated with these production systems, three Brazil nuts were studied: Native Anthropized Planting nut, Homogeneous Planting nut and Preserved Native Planting nut. In each environment, 12 modified Pet-Santa Maria traps were used during four sampling periods in the biennium (2018-2019). The collected material was identified at species level and the data submitted to faunal analysis, correlation and clustering. A total of 2,356 scolitans were sampled in 36 species in the three Brazil nut trees. Conserved Native Castanhal had the highest species richness (30), followed by Homogeneous Planting nut (27) and Anthropized Native Planting nut (27). The species Xyleborus affinis (Eichhoff, 1868) was classified as superdominant in the three environments, being considered a species of great economic importance for cultivated forest systems. The study of the occurrence of Cerambycidae coleobrocas was conducted in the area of the Homogeneous Planting nut with 12 ethanolic traps in four sampling periods between 2018 and 2019. In this survey a total of 28 individuals were distributed, distributed in 6 species, being Trachyderes succinctus (Linnaeus, 1758) and Chlorida festiva (Linnaeus, 1758) the most representative, which are also recorded attacking several forest species of economic interest. Cerambicidae abundance was correlated with climatic variables (temperature, relative humidity and precipitation), with no significance. In order to study the occurrence and spatial distribution of termites in the Homogeneous Castanhal, a 40-point grid sampling was adopted, and at each point buried cellulosic traps were buried at 20 cm depth, which remained in the field for 40 days. A total of 1405 individuals were sampled, of which 396 (28.1%) belong to the genus Nasutitermes and 1009 (71.8%) to the species Heterotermes tenuis (Hagen, 1858). The spatial distribution analyzed by the Morisita index indicated that the distribution pattern is of the aggregate type. The results obtained in this study demonstrate that the monitoring of coleobrocas and termites in native and homogeneous Pará nut systems are fundamental for the development of integrated pest management strategies, as well as for the understanding of the ecological dynamics of these agents in the systems forestry.

    C.moschata regarding
    phenological attributes, political viability and genetic divergence through germination
    characteristics. 11 traditional pumpkins varieties previously collected from seven rural
    properties located in the municipalities in the north of the state of Mato Grosso were
    evaluated. The study began in October 2018 with sowing and observations of
    phenological development occurred between November 2018 and March 2019. The
    experiment was installed in a randomized block design (DBC), with four replications
    and eleven treatments, in the municipality of Alta Floresta. The experimental unit
    (plot), consisted of 6 plants, the spacing between lines and between plants was 2.0 m
    x 2.0 m, in a total of 66 plants per block, totaling 264 plants. For pollen viability, the
    Alexander triple solution was used, the scores attributed to evaluate the phenological
    stages were based on the species Passiflora edulis Sims and the characteristics for
    the evaluation of genetic divergence were based on the recommendations of the
    Rules for Seed Analysis. In the phenological evaluations it was observed that all the
    studied varieties reached the complete phenological cycle. The UNEMAT 024 access
    showed precocity in the appearance of female flower buds and obtained the lowest
    phenological cycle, showing that it adapts to the environmental conditions of the
    region. The average viability was 86%, with access to UNEMAT 020 with the highest
    value of 96.40% and UNEMAT 024 with the lowest value to 70.15%. High pollen
    viability was verified in all collected varieties, indicating aptitude for pollination. In the
    analysis of genetic divergence, the characteristics with the greatest contribution to
    genetic divergence between varieties were fresh air mass and air length. The graphic

    and breeding programs, aiming at commercial production and the maintenance of the
    genetic resources of the species is UNEMAT 016, as it presented a high germinative
    percentage and a higher rate of germination speed, and the UNEMAT 017 access
    because it had high germination and low percentage of abnormal seedlings with only
    10%. The results obtained in this study can help farmers to improve their yields
    because it shows which varieties can be more effective to reach the final stage of
    production, in addition, this genetic material can be used in new studies involving
    breeding programs in the northern region of Mato Grosso.

  • Mostrar Abstract
  • Maise (Zea mays L) belongs to the Poaceae family to the genus zea. It constitutes a species of great economic importance, in addition to having a relevant role for traditional populations and family farming, it also has great diversity of use, ranging from human food, animal feed and raw material for agro-industries of different branches. Being an allogamous species with one of the greatest genetic variability among species of cultivated plants, the result of human selection and climatic adaptations suffered by the species over time, which allows its production in different environments all over the world. For all these attributes, maize is present in most small rural properties and, in several of them, the cultivated varieties have been maintained and cultivated throughout the generations. Usually, the maize variety is selected and maintained by these farmers for certain specific purposes of their property (human and animal food, silage production, flours) and, over time, adapted to the management and characteristics of their growing region. The practice of cultivating low-tech Creole maize often occurs on family properties, especially subsistence ones. Under these conditions, the cultivation of Creole maize results in a satisfactory productive yield, allowing the producer to make use of the selected seeds from one crop to another, through the practice of mass selection of the most vigorous plants. The present work aimed to characterize the genetic divergence by means of morphological characters of local varieties of Creole maize grown in the municipality of CarlindaMT and to work with the use of experimentation in the development of a research with high school students of E. E. Frei Caneca using a variety of Creole maize of scientific methodology. Ten varieties acquired from the producers were selected and 16 morpho-agronomic characters were evaluated, eight quantitative and eight qualitative. For the characterization of genetic diversity, the Principal Component Analysis method was used, based on the measures of dissimilarities obtained with the Mahalanobis Distance, using the computational resource of the GENES program. Principal component analyzes were useful to indicate the xii characteristics that most influenced the response variable. The characters that most discriminated the varieties were ear height, number of grain rows and average ear diameter. The graphic dispersion based on the first two main components revealed the formation of two distinct groups among the ten evaluated varieties, showing the intraspecific genetic diversity of the genotypes. The use of experimentation in the classroom, with research involving Creole maize, based on scientific methods, was carried out with high school students. The activities carried out through the development of this experiment with theoretical and practical activities in a school environment allowed the student to develop, in addition to skills related to understanding the content, a critical awareness regarding the preservation of the environment with the use of sustainable production practices, in addition to allow the development of practical work. The study was carried out at the Frei Caneca State School, in the municipality of Carlinda - MT, from April to July 2019. The development of the research took place in meetings with theoretical and practical activities and whose final objective was to develop with the participants a scientific work with the evaluation of pollen viability and post meiotic index in a variety of Creole maize that was planted in the schoolyard for this purpose, also included the application of a pre-questionnaire and at the end a post-questionnaire with the objective of assessing learning during the project development process. The activities carried out through the development of this experiment with theoretical and practical activities in a school environment allow the student to develop, in addition to skills related to understanding the content, a critical awareness regarding the preservation of the environment with the use of sustainable production practices, in addition to allow the development of practical work. The use of knowledge and methodology produced in the scientific environment in the teaching of biology contents enabled, in addition to formal and non-formal educational practice and its complementarity and the development of scientific education / culture, also contributed to the strengthening of teamwork, companionship and greater interaction between the segments involved in the project, developing a strategy that contributed to popularize science, enrich formal education and reinforce alternative modes of learning.
