The group of non-volant small mammals, consisting of marsupials and small rodents, is the most diverse ecological group of mammals in Neotropical forests. It represents more than one third of the diversity of mammalian species of the Atlantic Forest, comprising 105 of 298 species. However, the biogeographic and taxonomic knowledge of this group still has many gaps in the Atlantic Forest, especially referring to genera presenting complex and confusing taxonomy with cryptic species. For these, methodological advances in molecular biology in recent decades have been of great value, helping to solve many problems, especially when associated to morphological analyses of specimens in scientific collections. Thus, the main objective of this research internship is to learn and to apply molecular methods for two purposes: first, identify by molecular analyses (i. d. DNA Barcoding) taxa that could not be defined only by morphological characters; and second, run phylogeographic analyses with one rodent species (Euryoryzomys russatus) and one marsupial genus (Marmosops), which are widely distributed in the Atlantic Forest, in order to reveal their patterns of genetic structure and compare them with the patterns reported in the literature for different species of vertebrates and with the biogeographical models proposed of the Atlantic Forest.
