Abstract
Recent analyses of endemism and levels of antropic threat identified the so called hotspots targets for conservation. However, our knowledge about the origin and distribution of the biodiversity in those areas remains scarce. Such a deficiency limits our power of conservation with respect to the environmental changes caused by a man. One of the aims of this project is addressed to study the influence of Pleistocene climatic fluctuations of the herpetofauna and the levels of genetic diversity of frogs and lizards living in elevated and lowland regions of the Atlantic Forest. By combining special climatic modeling coupled to phylogeography, the project will be recording diversity patterns in an insufficiently studied, highly threatened and megadiverse region, bringing important contributions for the conservation of the remaining fragments of this hotspot. We will be also focusing on the role of mountains as areas favoring adaptive diversification of the herpetofauna, either as refuges to species adapted to cold climates during hot phases, or as evolutionary scenarios for ecogeographic speciation. We also proceed further our ongoing research with reptiles and amphibians from several Brazilian ecosystems under morphological, karyological, taxonomic, phylogenetic and phylogeographic approaches, contributing to a better understanding of their evolution and the biogeographic history of the continent. In a particular case we will be conducting a comparative phylogeographic study of a South American clade of lizards and its ecological equivalent in Africa in order to establish intercontinental correlations on their history and origin. The collections obtained in unsampled or little known areas in State of Sao Paulo and in other Brazilian ecosystems will improve the knowledge on our biodiversity, describing new rate which, associated to the phylogenetic and phylogeographic data obtained, will contribute to reevaluate conservation strategies to target species.
