Resumen:
Lontra provocax is an endemic species from Patagonia that
has been categorized as endangered by the International
Union for Conservation of Nature. In this study, noninvasive
molecular methods were used to investigate the genetic
diversity and haplotype distribution of L. provocax in
Argentinean Patagonia. We analyzed 150 scat samples
collected from 1995 to 2006 and obtained 13 sequences
of control region with 1 haplotype and 34 sequences of
cytochrome b with 4 haplotypes. The population of the
south of Patagonia (Tierra del Fuego and De los Estados
Island) showed a relatively high haplotype diversity (h 5

south of Patagonia (Tierra del Fuego and De los Estados

0.71) and was statistically different to the population of the
north (analysis of molecular variance, FST 5 0.15, P 5FST 5 0.15, P 5
0.018). We concluded that there are 2 different subpopulations
of L. provocax that deserve conservation attention
and that the southern population appears not to have
suffered a human-induced population bottleneck of the
sort typically experienced by various otter species around
the world.
