Brocket deer species, Mazama genus, are known as a group of mammals with important taxonomic issues. Mostly, this is due to a high level of homoplasy of morphological characters and high karyotyping diversity. These characteristics suggests that there are still many species to be described, once karyotyping differences among populations generates post-zygotic reproductive barriers. In ord…
The family Cervidae groups together species with a growing economic potential and endangered species. Karyotypes and phylogenetic position of many deer species are uncertain due to the lack of detailed scientific data. The extensive variation in chromosome numbers (2n=6-70) and structure makes this family suited for evolutionary studies based on interspecies molecular cytogenetic comparis…
The dwarf brocket deer (Mazaman nana) is a cervid species that occupies the forests of Southern Brazil and has been greatly affected by the drastic reduction of forested areas. It is also the neotropical deer less studied by Science. Aware about this situation, this project aims to determine the species basic ecological parameters such as distribution, abundance and sex ratio. Given the r…
Many taxonomic problems have been found in the brocket deer (Mazama Genus). Recent work have suggested that gray brockets do not belong to the Mazama genus, and M. nemorivaga (Amazonian gray brocket deer) and M. gouazoubira (Brown brocket deer) also integrate different genera. Meanwhile, M. nemorivaga is not accepted by some researchers as valid species. The present project aims to contri…

The genus Mazama groups Neotropical deer of medium to small size and simple antlers in males. The morphological similarity between the species of the genus has been described, contrasting with the karyotypic variation between them. Thus, the study of chromosomes is an efficient tool assisting the species delimitation in which karyotypical divergences may cause reproductive isolation. Howe…
The Cervidae family is the second most diverse of the Artiodactyla order, and its great variation makes it difficult to understand the evolutionary history and taxonomic classification of its species. Neotropical deer of the genus Mazama are distinguished by an expressive chromosomal polymorphism and a high morphological convergence, reasons for confusion in the classification and delimit…

The understanding of the geographic distribution and the taxonomic diversity of Mazama's species contains several gaps, mostly due to the elusive habits and great morphological similarity between species. Recently, a population of Mazama sp. belonging to the Odocoileina subtribe was discovered in the Rio Doce State Park, Minas Gerais, however it was not possible to identify it at the spec…
Understanding the interspecific interactions and the effect of landscape on habitat use is fundamental to understanding how biological community formations occur. Phylogenetically closer species tend to share greater ecological similarities and niche overlap. Thus, evolutionary adaptations are fundamental for the coexistence of congeners species. Brocket deer (Mazama genus) are a polyphyl…

Neotropical deer are members of the tribe Odocoileini, one of the most diverse group in the family Cervidae whose systematics is not yet fully understood. Most of the evolutionary lineages of the group already existed by the time of the Isthmus of Panama land bridge formation, but the spatial patterns of diversification and dispersal routes through South America have never been empiricall…
Density estimates of populations are fundamental for the formulation of management actions and policies for wildlife conservation. However, population density information is scarce for many species elusive behavior and that are difficult to observe in nature. Population density can be affected by interspecific interactions, such as competition. Non-invasive methods of density estimation m…
Deer are key ecological components of many ecosystems and while some species are declining, others are considered overabundant. Either to increase threatened populations or to reduce overabundant ones, reliable estimates of population density are essential to inform management effectively. Population estimates of elusive species, such as small neotropical forest deer, are difficult to obt…
Mazama rondoni is considered synonymous with Mazama nemorivaga due to the absence of significant morphological differences, however, the morphological characteristics of the genus Mazama are very similar, making it necessary to use genetic analyzes. Museum specimens are widely used to solve taxonomic problems through morphological and molecular studies, in which museum collections DNA has…
Although the species of the Mazama genus differ in the values of their diploid number, they are closely related and similar morphologically. Due to this, there were errors in the taxonomic classifications and new species were discovered. The chromosomal evolution of the Mazama species from the ancestral hypothetical karyotype, retained by the species Mazama gouazoubira, is poorly underst…
