Formatted Abstract/Summary
Forest areas in Colombian Llanos are highly degraded due to the expansion of palm oil crops, petrol extraction, and other human interferences, making primate species in Colombia more susceptible to population reduction and local extinction. An eight-year study of primate density monitoring was conducted in five forest fragments of different sizes in San Martín, Colombian Llanos. Alouatta seniculus, Sapajus apella, Callicebus ornatus, Saimiri sciureus albigena, and Aotus brumbacki were present in the fragments. Direct visual contacts were made in small (1–10 ha) and medium (10–100 ha) fragments. Primate density in an extra-large fragment (1,050 ha) was calculated using line transect method. Results showed that population density for A. seniculus ranged from 0.81 to 78.57 ind/km2, S. apella, 0.95–52.98 ind/km2, C. ornatus, 1.07–54.76 ind/km2, S. s. albigena, 3.85–170.24 ind/km2, and A. brumbacki, 3.26–13.10 ind/km2. Most species reported in small and medium fragments have a higher population density than those reported in other studies, except for A. seniculus, which fell in a normal range. Densities in the extra-large fragment for Alouatta, Callicebus, and Sapajus are similar to that reported in continuous forest, while densities for Saimiri was lower than that reported for continuous forest. Variations that affected population density among fragments are due to differences in-group composition per species, vegetation, and size of the fragment. All primate species present in this region use fencerows as part of the landscape matrix to cross among fragments. Increasing the connectivity between fragments is necessary in this region to improve sustainability of this primate community.
