Abstract

The biota of the Atlantic forest is not evenly distributed but structured in areas of endemism as a result of their isolation. The identification of barriers is an essential component to understand the origin and evolution of organisms and propose measures for their conservation. These areas of endemism vary in number and size, depending on the taxonomic group studied and the methodology employed. The so-called area of endemism Serra do Mar (which spreads from the State of ES to RS), is incongruent with different studies in its southern boundary. Biogeography of organisms with low vagility, and high sensivity to environmental changes such as land planarians (Platyhelminthes), can contribute to this debate and also to detect priority areas for biological conservation. Parsimony analysis of endemicity and analysis of endemicity of flatworms fauna from six areas will be applied within the focal region, this delimited between SP and RS States. Molecular phylogenetic analyses (maximum likelihood, Bayesian inference) of widespread groups are aimed at determining relationship hypotheses of the areas of endemism. To detect which areas should be given priority for conservation, the environmental quality of them will be compared through indexes of diversity, similarity, and relative endemism. Almost all specimens have been collected already. The species will be delimited both morphologically (histology) and molecularly (Bayesian Phylogenetics and phylogeography, Generalized Mixed Yule Coalescent), and a portion will be described formally. Two specialists in endemism and molecular analyses, respectively, and a doctoral student (on a CNPq scholarship) will collaborate with the project. (AU)
