Tt. Rieger et al., ALLOZYMIC CHARACTERIZATION AND EVOLUTIONARY RELATIONSHIPS IN THE BRAZILIAN AKODON CURSOR SPECIES GROUP (RODENTIA-CRICETIDAE), Biochemical genetics, 33(9-10), 1995, pp. 283-295
The present study involved an electrophoretic survey of 22 protein loc
i in 269 individuals belonging to three species of the genus Akodon, A
. aff. cursor (2n = 16), A. cursor (2n = 14/15), and A. montensis (2n
= 24/25/26), collected in Eastern Brazil. The joint results of gene di
versity, genetic distances, phenetic analyses, and phylogenetic trees
suggested that A. aff cursor has recently separated from A. cursor and
that the three species have experienced a recent chromosomal divergen
ce followed by low allozyme differentiation. These data are in agreeme
nt with their classification as sibling species.
