Population Structure and Genetic Diversity of the Endangered South American Giant Otter (Pteronura brasiliensis) from the Orinoco Basin in Colombia: Management Implications and Application to Current Conservation Programs.

Abstract excerpt

Endangered giant otters, Pteronura brasiliensis, are found along the Amazon and Orinoco rivers and most of their tributaries. Hunting in the mid-1970s pushed giant otter populations to the brink of extinction. We studied population structure and genetic diversity of giant otters from Colombia's Orinoco basin using analyses of partial mitochondrial DNA control region sequences obtained from scat material. We...
