The Neotropical deer genus Mazama is characterized by homoplastic morphological characters, a high karyotypic diversity, and polyphyletic condition. species of the have been recovered into two multigeneric lineages, subtribes Odocoileina Blastocerina, tribe Odocoileini (New World deer) in family Cervidae. Within gray brockets include non-sister species, Subulo gouazoubira, occurring south Amazon region, Passalites nemorivagus, Guianas region. We clarify taxonomic status phylogenetic position...
Abstract The gray brocket deer, Mazama gouazoubiraG. Fischer, 1814, occurs in South America and presents an extensive degree of morphological genetic variability. Previous phylogenetic research showed that the genus is polyphyletic imposed designation a different genus-group name for M. gouazoubira. We aimed to review clarify taxonomy gouazoubira through proposal updating nomenclature this taxon by characterization specimens collected close original type locality (topotypes). topotypes were...
Mazama nemorivaga (Cuvier, 1817) is a gray brocket deer that inhabits the Amazon region. An assessment of previous studies revealed inconsistencies in its current taxonomic classification, suggesting need for an update genus classification. A repositioning this species proposed through collection specimen from type locality (French Guiana) with subsequent morphological (coloring pattern, body measurements, and craniometry), cytogenetics (G Band, C conventional Giemsa, Ag-NOR staining, BAC...
The red brocket deer Mazama americana Erxleben, 1777 is considered a polyphyletic complex of cryptic species with wide chromosomal divergence. Evidence indicates that the observed divergences result in reproductive isolation. description neotype for M. allowed its genetic characterization and represented comparative basis to resolve taxonomic uncertainties group. Thus, we designated synonym rufa Illiger, 1815 tested recognition as distinct from analysis morphological, cytogenetic molecular...
Chromosomal polymorphism plays a major role in speciation processes mammals with high rates of karyotypic evolution, as observed the family Cervidae. One remarkable example is genus Mazama that comprises wide inter- and intra-specific chromosomal variability. To evaluate impact polymorphisms reproductive barriers within Mazama, inter-specific hybrids between gouazoubira nemorivaga (MGO × MNE) cytotypes americana (MAM) differing by tandem (TF) or centric fusion (Robertsonian...
The taxonomy and phylogenetics of Neotropical deer have been mostly based on morphological criteria needs a critical revision the basis new molecular cytogenetic markers. In this study, we used variation in sequence, copy number, chromosome localization satellite I-IV DNA to evaluate evolutionary relationships among eight species. Using FISH with satI-IV probes derived from Mazama gouazoubira, proved presence blocks peri/centromeric regions all analyzed deer. Satellite was also detected...
Cervids are characterized by their greatest karyotypic diversity among mammals. A great of chromosome numbers in notably similar morphological groups leads to the existence several complexes cryptic species and taxonomic uncertainties. Some deer lineages, such as those Neotropical deer, stand out for a rapid chromosomal reorganization intraspecific polymorphisms, which have not been properly explored yet. For that reason, we contribute study karyotype taxonomy producing characterizing new...
The genus Mazama stands out among the Neotropical deer due to their wide intra and interspecific karyotypic diversification, which is associated with an accentuated chromosomal fragility. There are reports of heterozygous Robertsonian translocation (RT) carriers in a free-range population gouazoubira (brown brocket deer), as well captive animals this other species genus. To analyze possible negative impacts chromosome rearrangements on reproductive fitness carriers, we performed analysis...
Abstract Deforestation and road construction have inflicted negative effects on wildlife populations. To contribute to the comprehension preservation of species, this study aimed evaluate collared anteater presented a reference center located in São Paulo state, Brazil. Furthermore, locations where animals were most frequently found determined. Data anteaters (Tamandua tetradactyla) examined at Center for Medicine Research Wild Animals (CEMPAS) evaluated retrospectively period 13 years. A...
The Yucatan brown brocket deer was initially described as Mazama pandora Merriam, 1901. Phylogenetic analysis of mitochondrial DNA recovered the species sister group genus Odocoileus and subsequently repositioned to this naming (Merriam, 1901). However, there is still a lack taxonomic consensus that could assist in nomenclature definition species. We aim clarify taxonomy O. through an integrative assessment using morphological, cytogenetic, molecular data from recently collected specimens....
Mazama temama, commonly named Central American red brocket deer, was described in Veracruz, east-central México. Cytogenetic studies have characterized differentiated karyotypes observed captive individuals of the species with a diploid number (2n) = 49 to 50, recently collected neotype 44 and fundamental (FN) 70, specimens Campeche southeast México 47 70. Then, we used BAC probes derived from cattle genome aiming describe chromosomal differences M. temama karyotypic variants. We compared...
