Distribution and abundance of Ateles belzebuth E. Geoffroy and Ateles chamek Humboldt (Cebidae: Primates) in the Pacaya Samiria National Reserve, Peru

The study deals with the habitat, inter-especific associations, group size and population density of two Ateles species that inhabit the Pacaya Samiria National Reserve. Data were collected during inventories and transect censuses between january 1997 and february 1999, september — october 2000, august –- september 2002 and January 2003. On the left bank of the Río Samiria, Ateles balzebuth E. Geffroy and Ateles chamek Humboldt share the habitat forming mixed groups. Average group size for A. belzebuth was 5,1 individuals/group and for A. chamek 7,3 individuals/group. Estimated population density for A. belzebuth was 1,02 individuals/km2 and for A. chamek 0,51 individuals/km2 . We discuss and analyze the factors that may have influenced the drastic reduction of both populations.

En el presente trabajo se dan a conocer las observaciones sobre el hábitat, las asociaciones inter-específicas, tamaño de grupo y densidad poblacional de las dos especies de Ateles que habitan en la Reserva Nacional Pacaya Samiria. Los datos fueron colectados mediante inventarios y censos por transecto en los periodos de enero de 1997 a febrero de 1999, setiembre -– octubre 2000, agosto -– setiembre, 2002 y enero 2003. En la margen izquierda del Río Samiria, Ateles belzebuth E. Geoffryoy y Ateles chamek Humboldt comparten el hábitat formando grupos mixtos. El tamaño promedio de grupo para A. belzebuth fue 5,1 individuos/grupo y para Ateles chamek 7,3 individuos/grupo. La densidad poblacional estimada para A. belzebuth fue 1,02 individuos/km2 y para A. chamek 0,51 individuos/km2 . Se discuten y analizan los factores que habrían influido para la drástica reducción de ambas poblaciones.
