Thaís B. Guedes (Researcher Leader)
I am a herpetologist and biogeographer. Currently, I am a professor at the São Paulo State University (UNESP, campus of Rio Claro), Young researcher from Fundação de Amparo à Pesquisa do Estado de são Paulo (FAPESP 2121/07161-6) and CNPq productivity scholarship holder (304503/2025-8); and I am also an Associate Researcher at the Gothenburg Global Biodiversity Center at the University of Gothenburg (GGBC; Sweden).
​
I am interested in to understand the patterns of distribution of biodiversity and how these patterns changed along time and space. I investigate these subjects on global, regional and local scales by integrating species distribution datasets with phylogenies and traits of the biota, with implications for conservation.
Thus, my studies include mainly analysis of biodiversity (patterns of richness, phylogenetic diversity and endemism, functional diversity), biogeography (mapping species distribution, regionalization, history and conservation), macroecology and modelling of species distribution (niche evolution, changes of species distribution under climate change scenarios). I also investigate topics related to natural history, taxonomy, reproductive biology and behaviour. I use mainly amphibians and reptiles (herpetofauna) as models in my studies.
​
In 2021, I became the author of the List of Reptiles of Brazil, published periodically by the Brazilian Society of Herpetology.
