Microsatellite variation in two populations of mountain lions (Puma concolor) in Texas

Genetic variation at 10 microsatellite loci was examined for mountain lion populations from south and west Texas. Texas mountain lions had less genetic variation than previously reported for the species in other parts of its range. The sampled genetic variation defined the two surveyed localities as distinct groups of mountain lion in south and west Texas with evidence of reduced gene flow between these groups. These data suggest that mountain lions within the state should be partitioned into at least two management units.
