Renan Maestri nous présentera ces travaux sur la diversification et disparité morphologique chez les rongeurs néotropicaux.

 

 

 

 

Mammalian biodiversity tends to increase in the tropical and topographic complex regions of South America. I will show patterns of species richness and turnover of rodents across South America and then explore how morphological disparity is distributed across geography for the most species-rich clade of South American rodents, the sigmodontines. This will allow answering questions related to the origin of species diversity and phenotypic diversification of these rodents. Overall, morphological disparity standardized to control for richness indicates that the Andes and the Amazonia have lower disparity (despite high richness) compared to mountainous regions in the Atlantic Forest. In general, eastern South America, in special mountainous regions of the Atlantic forest, seem to be the hotspots of morphological disparity while still maintaining one of the highest richness hotspots for these rodents.
