The biological sciences are facing several challenges and one of the most important has been to describe, quantify and understand biological diversity and the mechanisms that generate and maintain the diversity. More intriguing, it has been to evaluate why in some lineages high species richness in accompanied by ecomorphological disparity while in others not. The backbone of this proposal…
The tribe Oryzomyini is one of the most diverse clades of subfamily Sigmodontinae, harboring nearly 30 genera and 130 species. Modern definition of this tribe includes sylvan and pentalophodont forms, but also pastoral and tetralophodont taxa, which represents a dramatic shift on the classic paradigm. Despite these advances, some issues on the evolution of the subfamily, as the mesoloph e…
With a large part of the biodiversity of mammals represented by rodents, this group of mammals has been the focus of different studies that seek to better understand its diversification processes. However, it is still unclear how incomplete taxonomic sampling, more robust phylogenetic hypotheses and geography can influence the inference of these diversification processes. Thus, the presen…
Among the Sigmodontinae rodents, the tribe Akodontini represents the second largest in diversity, covering 16 genera and 85 species. Although widely distributed in South America, these rodents are absent trough most of Chile and Southern Patagonia, and present a particular low diversity in Amazonia. The phylogenetic relationships of this tribe, as well as the delimitation of new genera an…
The great biodiversity of the Amazon region has attracted the attention of naturalists since the 18th century. However, it is also a place of important economic activities in Brazil and has become the target of human impacts that put all this biodiversity at risk, as well as the forest resilience and indigenous culture. For this reason, recognizing and describing Amazonian biodiversity as…
Subtribe Vampyressina is one of the most diverse clades among fruit bats of subfamily Stenodermatinae, with seven genera classified in 42 species. Previous studies have suggested the existence of niche partitioning among the species of Vampyressina that occur in the same area, as up to 12 species of the seven genera of the subtribe can occur in sympatry. This hypothesis is partially stren…
South American squirrels are extremely diverse animals, whether in morphological characteristics of each species or in its ecological niche. In spite of present themselves as unique organisms in the continent's biodiversity, countless aspects of these animals still lack information and new studies, such as their taxonomy. Recently, a new review was made to classify south American squirrel…

Bamboo rats of the genus Dactylomys are arboreal echimids (Rodentia: Echimyidae) that inhabit the Amazon region and surroundings, commonly found close to watercourses, associated with lowland vegetation. Advanced genomic methods were the main source to test their higher-level systematics in the last decade, however, some genera such as Dactylomys are still neglected, likely due to difficu…
Despite the ecological importance of the family Sciuridae, the taxonomy and systematics of several groups, particularly those inhabiting Neotropical forests, is still very controversial and lacks broad and robust revisionary studies. The Neotropical squirrels remained forgotten by systematists for a long time, and only recent efforts have been made trying to fill this large gap. Vivo and …
The preservation of small vertebrates as subfossils or fossils is extremely rare, because it is necessary the congruence of chemical, physical, geological and biological factors to avoid destruction of bones and teeth by the process of decomposition and weathering. Although rare, testimonies of such fauna are found with some frequency in excavations in rock shelters or caves, representing…
Remarkable advances on the knowledge of the Tribe Oryzomyini were achieved in the last years, but important aspects regarding its diversity and evolutionary and biogeographic history remain to be established. Important issues are: the four clades obtained in several analyses with the molecular markers cytochrome b and IRBP [A, B, C and D], will also be recovered in analysis with denser ta…
