Two species of frugivorous atelids, Ateles chamek and Lagothrix cana , occur in southwestern Brazilian Amazonia. Populations were surveyed at 36 sites in the state of Rondônia. Ateles chamek is widespread, but the distribution of L. cana is limited by a combination of riverine barriers and ecological factors, possibly including competition with A. chamek . Groups of L. cana were generally larger and more abundant than those of A. chamek , even in syntopy. The transitional forest that predominates in the extreme south of Rondônia (Hylea-cerrado ) is not a barrier to either species, with both species being tolerant of habitat disturbance when hunting pressure is low.
