La nutria de río neotropical (Lontra longicaudis annectens) se encuentra amenazada en México y para diseñar estrategias reales de conservación, son necesarios estudios básicos de su biología yecología. Se evaluaron la dieta y abundancia entre julio de 1999 y agosto del 2000 en los ríos Ayuta, Copalita y Zimatán en la costa de Oaxaca. Considerando una estimación de cuatro nutrias en 147.5 kmdel río Ayuta. ...

Water erosion is one of the main factors that lead to the process of soil degradation, with impacts ranging from reducing productivity to losses of natural resources. Thus, this work aimed to estimate soil losses performing RUSLE model and to verify the effect of changes in land use changes, from 1990 to 2007, in the watersheds of the rivers Lontra and Manoel Alves Pequeno,Tocantins State-Brazil. Water erosion in the river Lontra ranged from “slight” (51.3%) in the central region of the basin (dominance ...

Abstract: Southern river otter densities of 0.03 to 0.62/km of river were estimated for three rivers of the coast of the Mexican State of Oaxaca by the number of feces found on transects. The estimated population for the 19 perennial rivers of the state was 495. Scat analysis showed that crustaceans, fish, insects and amphibians are the main components of the otter’s diet.

Introduction: Considering the general deterioration of Michoacán rivers, increased poaching, the failure to enforce relevant laws in the last 10 years, and the absence of a detailed assessment of the current status of the river otter ( Lontra longicaudus ) in the state of Michoacán, our main goal was to collect and analyze all available historical and recent evidence for the occurrence of the river otter in this state. The study focused on three regions for which field recordings were obtained during ...

Although the Neotropical otter Lontra longicaudis has a wide distribution in the American continent and in Colombia, there are few studies on the ecology particularly at Andean enclaves. Objective : We evaluated the distribution, relative abundance, and habitat of the Neotropical otter ( L. longicaudis ) during the dry season (July 2012) at the tributaries of the Guaroco river basin, in the Andean arid region of La Tatacoa, Colombia. Methodology : We evaluate 23.6 km (360 man/hours) of rivers and streams, ...
