Distribution and population status of the giant otter Pteronura brasiliensis in Bolivia Distribucion y estado de la poblaciones de Londra Pteronura brasiliensis in Bolivia

, : Distribution and population status of the giant otter Pteronura brasiliensis in Bolivia Distribucion y estado de la poblaciones de Londra Pteronura brasiliensis in Bolivia. Revista Boliviana de Ecologia y Conservacion Ambiental. Diciembre; 12: 111-134

The giant otter (Pteronura brasiliensis) is one of the most charismatic mammal species in South America, but it is also one of the most endangered. It has been reduced to very low population numbers because of uncontrolled hunting in the 1950s and 60s. Until recently, it was thought that no viable Pteronura brasiliensis populations existed in Bolivia. However, recent surveys indicate that giant otter populations are recovering in the ltenez - Guapore river basin, in the north - east of Bolivia. In this review, we present new data on the distribution and population status of this species in the Del Plata and Amazon river basins. The total Pteronura brasiliensis population in the ltenez - Guapore basin probably exceeds 350 individuals. A discussion on habitat preferences, conservation, and research strategies is also presented.
