Diversity of mtDNA in Southern River Otter (Lontra provocax) from Argentinean Patagonia
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 P...

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 = 0.71) and was statistically different to the population of the north (analysis of molecular variance, FST = 0.15, P = 0.018).
