Abstract

Studies aiming biodiversity characterization, species distribution, endemism, ecology, risks or threats of extinction are fundamental to understand the evolutionary history of the fauna and biomes, also being important for the implementation of biological conservation practices. The characterization of Neotropical biodiversity and identification of mechanisms that have shaped the diversity of lineages still require broad scientific investment. The history of Neotropical biomes is complex and geological events of the Neogene and environmental changes of the Quaternary played an important role in organism diversification. In this respect, this project employs small mammals and snakes as model-groups, aiming: (I) characterize biodiversity based on molecular systematics, morphology and geographic distribution, which are the main objective of all projects, and in the case of rodents karyological data will also be considered (II) investigate evolutionary patterns of different lineages, inferring associated processes based on cytogenetic, phylogenetic, phylogeographic, and diversification dating analyses; (III) infer biogeographic patterns in spatial and temporal scales, combining the findings of this work with literature information. Such information will assist in the inference of diversification dates of lineages and biomes of the Neotropical region, as well as factors responsible for these processes. Small mammals and snakes are appropriate model-groups for this type of study because they are widely distributed in Neotropical biomes and play an important role in medical and public health, since some of these lineages can be vectors of diseases and responsible for envenomation, respectively. This project is divided into nine subprojects in which the main objectives are presented at the end of each one of them. (AU)
