RESUMO:

Community structure is a fundamental concept in ecology, referring to the organization and patterns of interaction between populations of different species that coexist in a given habitat. Understanding these dynamics and associated environmental factors is essential to guide sustainable management strategies and preservation of the Cerrado's biological wealth, directly contributing to the Sustainable Development Goals (SDGs), especially SDG 15, which prioritizes the protection of terrestrial life. Lizards, belonging to the order Squamata and suborder Lacertilia, constitute a diverse group with distinct morphological, behavioral and ecological characteristics. In Brazil, where there are 295 species of lizards, the Cerrado is home to 74 species, of which 45% are endemic. However, these reptiles face significant challenges due to habitat loss and climate change. Recognized for its environmental complexity, the Cerrado comprises a variety of habitats, but is subject to considerable threats, including the expansion of agriculture and livestock. The environmental heterogeneity of the Cerrado plays a fundamental role in sustaining the taxonomic, functional and phylogenetic diversity of lizards. While taxonomic diversity evaluates the richness, composition and abundance of species, functional diversity analyzes behavioral, physiological and ecological traits. At the same time, phylogenetic diversity takes into account the evolutionary relationships between species. The combination of these approaches provides a comprehensive understanding of the interactions and ecological and evolutionary processes present in Cerrado lizard communities. This specific study focuses on lizard assemblages in an anthropized area of the Cerrado in the Serrana Province. Divided into two chapters, the first, "Spatial variations in the taxonomic, functional and phylogenetic diversity of lizards in heterogeneous habitats and under anthropogenic influence in the Cerrado", investigates the possible variation in diversity between different phytophysiognomies. The second chapter, "Influence of environmental factors in different habitats on taxonomic, functional and phylogenetic diversity in lizard assemblages in the Cerrado", explores how the factors temperature, humidity, altitude, litter availability, presence/absence of grasses and the existence of rocky stratum in different habitats and periods (dry/rainy), influence the structuring of lizard assemblages. In short, the research highlights the importance of conservation, especially in environments influenced by human action, reinforcing the need to understand and preserve the diversity of this unique ecosystem
