Abstract excerpt

The variability at eight microsatellite loci was analyzed in 88 individuals of Ctenomys lami, a species of tuco-tucos. Initially considered as three subpopulations, the estimated Fst values ranged from 0.0007 to 0.0589. Additionally, a Bayesian approach presented probabilities of 0.9933 for the existence of only one population. A Fis value of 0.19 could indicate an incipient structure. Sexual dimorphism was...
