PATTERNS OF LIZARD ASSEMBLY DIVERSITY IN A CERRADO AREA OF THE SERRANA PROVINCE, MATO GROSSO, BRAZIL
Community structure; Reptiles; Cerrado; Diversity
Community structure is a fundamental concept in ecology, referring to the organization and interaction patterns among populations of different species coexisting within a given habitat. Understanding these dynamics and the associated environmental factors is essential for guiding sustainable management strategies and preserving the biological richness of the Cerrado, directly contributing to the Sustainable Development Goals (SDGs), particularly SDG 15, which prioritizes the protection of terrestrial life. Lizards, reptiles of the order Squamata, are a highly diverse group, with a wide variety of species distributed globally. They possess valuable traits for ecological studies. In the Cerrado, the lizard fauna is composed of habitat specialist species. However, these reptiles face significant challenges due to habitat loss and climate change. The Cerrado is recognized for its environmental heterogeneity, which includes a diversity of factors shaping different habitats. However, this ecoregion is under constant threat, primarily due to the expansion of agriculture and livestock farming. The diversity of Cerrado habitats plays an important role in maintaining the taxonomic, functional, and phylogenetic diversity of lizards. While taxonomic diversity assesses species richness, composition, and abundance, functional diversity analyzes behavioral, physiological, and ecological traits. Simultaneously, phylogenetic diversity considers the evolutionary relationships between species. The combination of these approaches provides a comprehensive understanding of the interactions and ecological and evolutionary processes present in lizard communities of the Cerrado. This specific study focuses on lizard assemblies in a human-altered area of the Cerrado in the Serrana Province. Divided into two chapters, the first, "Taxonomic, functional, and phylogenetic diversity of lizard assemblies in different Cerrado habitats" investigates the potential variation in diversity across different vegetation types. The second chapter, "Influence of environmental factors on the taxonomic, functional, and phylogenetic diversity of lizard assemblies in a Cerrado area," explores how different environmental and habitat factors influence the diversity patterns of lizard assemblies.
