Distribución y abundancia de la nutria neotropical (Lontra longicaudis annectens) en Tlacotalpan, Veracruz, México

A study conducted between 2007 and 2008 in Tlacotalpan, Veracruz, Mexico, revealed significant variation in the abundance of the neotropical otter (Lontra longicaudis annectens) across different habitats during distinct climatic seasons. Abundance estimates ranged from 1.22 to 0.43 otters per kilometer along the Río Papaloapan and from 0.61 to 0.21 otters per kilometer in nearby streams and lagoons, with higher densities observed during the hurricane season (November 2007) compared to the dry season (April 2008). The research employed a combination of field monitoring—including tracking scat, latrines, burrows, and direct sightings—and community interviews, which highlighted local awareness and support for otter conservation. This study underscores the ecological importance of neotropical otters in Tlacotalpan's aquatic ecosystems and the need for their protection.
