Morphologic and Cytogenetic Description of the Small Red Brocket (Mazama bororo Duarte,1996) in Brazil

The surprising evolutionary history of South American deer

“…For instance, a morphological study based on coloration and craniometrics of an extensive sampling of the red brocket species from Brazil failed to distinguish two different species of red brockets (M. americana and M. bororo; Rossi, 2000). Furthermore, the identification of these cryptic species becomes more difficult in areas where several species occur in sympatry (Duarte and Jorge, 2003). The external morphometric analysis alone also showed low resolution power to discriminate within the brockets (Figure 1).…”

“…Descriptions based on morphological taxonomic revisions of the genus Mazama have generated between 6 (Czernay, 1987) and up to 18 (Allen, 1915) species. Taxonomic revisions of this group based on cytogenetic data have proven to be more useful in comparison with morphological approaches in recognizing new cryptic species of red brockets from Mexico (M. temama; Groves and Grubb, 1987), and more recently from Brazil (M. bororo; Duarte and Jorge, 2003).…”

“…We took 11 body measurements (head length, head width, distance between eyes, ear length, width of the mandible base, metacarpi length, metatarsi length, body length, thorax circumference, height, and weight) from 138 anesthetized animals (27 Mazama americana,5 M. bororo,61 M. gouazoubira,36 M. nana,8 M. nemorivaga and 1 Ozotoceros bezoarticus) following the procedures described in Duarte and Jorge (2003). A cluster analysis was performed to measure the similarity among the morphology of individuals and discriminate species and populations (Sneath and Sokal, 1973 Cytogenetics.…”

“…A cluster analysis was performed to measure the similarity among the morphology of individuals and discriminate species and populations (Sneath and Sokal, 1973 Cytogenetics. Cytogenetic data were obtained from fresh blood or frozen lymphocytes (Duarte et al, 1999) and fibroblast cultures (Duarte and Jorge, 2003), from 213 animals…”

Amplifiability of mitochondrial, microsatellite and amelogenin DNA loci from fecal samples of red brocket deer Mazama americana (Cetartiodactyla, Cervidae)

“…Urgent studies regarding the distribution, abundance and diversity of these species are required. Among these, the red brocket is a species that has the greatest gaps in knowledge regarding its taxonomy and ecology (Duarte and Jorge, 2003;Duarte et al, 2008;Varela et al, 2010;Abril et al, 2010).…”
