The surprising evolutionary history of South American deer

Different responses to doxorubicin-induced chromosome aberrations in Brazilian deer species

“…Furthermore, there were no statistically significant differences between M. americana (2n = 52/53) and M. nana (2n = 36). Another explanation could be a phylogenetic correlation of the genus Mazama; however, this hypothesis is also not viable since there is strong molecular evidence demonstrating that M. americana and M. nana belong to a different clade and that M. gouazoubira is phylogenetically related to B. dichotomus (Gilbert et al, 2006;Duarte et al, 2008). This hypothesis only partially agrees with results seen in M. americana and M. nana, but apparently these results are not sufficiently consistent.…”

“…Cytogenetics and molecular phylogenetics have contributed greatly to the knowledge of the evolutionary complexity of deer family Cervidae (Neitzel, 1987;Fontana and Rubini, 1990), particularly those of the genus Mazama (Mammalia; Cervidae), a group of small to medium-sized forest deer with spike-like antlers from Central and South America, characterized by their phenotypic homogeny in the presence of a polyphyletic origin (Gilbert et al, 2006;Duarte et al, 2008). Some cytogenetic studies have demonstrated very complex processes of chromosome evolution, being more intense in the reddish brocket group (Mazama americana, M. nana and M. bororo) than in grayish brockets (M. gouazoubira and M. nemorivaga).…”

“…The Red brocket deer (M. americana) is also archaeologically present on Tobago (Steadman and Jones 2006). Recent Cytogenetic and mtDNA studies of Mazama demonstrate considerable karyotype and molecular diversity in these species and highlight their evolutionary history (Duarte, González, and Maldonado 2008;Giovas, in press).…”

“…In fact, phylogenetic analyses of cytochrome-b sequence data do not support the monophyly of Mazama americana, which was recovered as two weakly supported haplogroups in an unresolved polytomy with Odocoileus hemionus, O. virginianus, and two other species of Mazama by Duarte et al (2008). Subsequently, Abril et al (2010) recovered two haplogroups of M. americana with stronger support by sequencing the mitochondrial control region and by omitting sequences from some of the other odocoileine taxa included in Duarte et al 's (2008) analysis.…”
