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 has a high level of intraspecific chromosomal variation, which can induce anomalies during meiotic pairing and consequent failures in gametogenesis, forming a post-zygotic reproductive barrier and potentially promoting the speciation process. The short-handed deer (Mazama nana), the smallest Brazilian deer, also presents a wide karyotypic variation, with eight variants de…
Population densities are fundamental information for in situ species managementand conservation assessment but can be particularly challenging to obtain for elusiveand cryptic species. Additionally, inconsistencies in population density data can resultin inadequate wrong classifications and hinder conservation plans. Non-invasivemethodologies, such as Faecal Standing Crop (FSC), have been…
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 southern wood deer (Mazama rufa) was recently revalidated as part of the cryptic species complex of the genus Mazama, being a species that is experiencing population decline in its natural habitat. One of the strategies for conserving the species is the use of reproductive biotechnologies, such as semen cryopreservation. In cervids, semen cryopreservation is predominantly carried out …
Cytogenetic studies are an extremely important tool for revalidating taxa and distinguishing between cryptic species of deer, as occurred with the Mazama rufa species, previously considered to be Mazama americana. In order for these studies to be carried out, it is necessary to collect tissues from the specimens and transport the material to the laboratory for cell cultivation, which requ…
Biobanks were created to store biological material for research purposes, as well as to serve as a source of material for use in reproductive biotechniques in the conservation of endangered species. To do this, the material must maintain all viable cell structures, without damaging the genetic material and cell structures. Therefore, one of the challenges still faced is the movement of li…

Throughout the evolutionary process, genomic rearrangements arise within germ cell lines, during meiosis. Both genetic and mechanistic factors influence mammalian meiotic recombination landscapes. The former is shaped by the evolutionary history of each taxon and the latter by chromosomal reorganizations, which can alter meiotic recombination by suppressing recombination within chromosome…
Among the Artiodactyla, Cervidae family, Neotropical brocket deer are represented by the genera Pudu, Pudella, Bisbalus, Mazama, Subulo and Passalites, and known to have a marked karyotypic diversity, with frequent observations of polymorphisms and chromosomal rearrangements. Another major variation is seen by the presence or absence of B chromosomes, both inter- and intraspecies. All sp…
Sheep is a domestic ruminant species used as experimental model for studying reproductive, metabolic and in vitro-growing features of non-domestic ruminant species. Therefore, it is an optimal model to develop collection, long-term preservation and in vitro protocols for testicular tissue of neotropical deer aiming to properly storage it in cryobanks for conservation purposes. The main ob…
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…
