Elucidating the evolution of the red brocket deer Mazama americana complex (Artiodactyla; Cervidae).
The red brocket deer Mazama americana is a neotropical species that exhibits extensive karyotype variation under an unvarying morphotype. In order to deduce red brocket deer genetic units for conservation, gene flow between populations, and genetic variation, we initiated a cytogenetic and molecular genetic study based on representative samples from throughout their Brazilian geographic range. These data represent the first cytotaxonomical and molecular systematics, and although sample sizes are limited, our results clearly suggest that red brocket deer populations are significantly differentiated with respect to karyotypes and the mitochondrial sequences analyzed. We clearly recognized 2 independent species, and we will be focusing further research in analyzing the meiotic dynamic to determine the existence of other evolutionarily significant units under the red brocket complex.
