Habitat suitability and anthropogenic correlates of Neotropical river otter (Lontra longicaudis) distribution

The Neotropical river otter Lontra longicaudis is a top predator in many South and Central American aquatic freshwater systems. Its current category in the International Union for Conservation of Nature is "data deficient," which makes it imperative to determine the appropriate conservatio...
