Abstract

POZO R., Wilmer E.. Habitat preferences of six non-atelidae primates of Yasuni, Ecuador. Ecol. apl. [online]. 2004, vol.3, n.1-2, pp.128-133. ISSN 1726-2216.

The tropical rain forest contains great numbers of species living sympatrically. The knowledge of the uses of the habitat permits the understanding of how the competition for space is reduced between species. This study reports data on habitat use of non-atelidae primates found in the Yasuni National Park, Ecuador. The high forests on the mountain slopes and ridges and the layer below the canopy are the habitat most utilized by the primate community, but they do so in different frequencies with respect to those in the forest, and in significantly different ways from the other sympatric species. This demonstrates that the non-atelidae primates at Yasuní reduce competition through various methods of habitat use.
