Abstract (en):
The llanos region in eastern Colombia exhibits great biodiversity, and is being threatened by agro-industrial
processes such as oil palm plantations. However, information about the mammals associated with these landscapes is very limited. We measured richness and capture frequencies of medium and large sized mammals using camera traps in an oil palm plantation and surrounding natural ecosystems, in the seasonally flooded savannas of the Department of Casanare, Colombia. We identify 16 medium to large mammals, and two species of mice, with a survey effort of 3937 camera/days. Capture frequencies varied according to the land cover type. All species were present in the gallery (riparian) forest. Nine species were also detected inside the oil palm plantation and six in savannas. The mammals we found in the plantation were mainly mesopredators and generalist species, while the mammals detected in forest have more restricted diets. We discuss the importance of the gallery forests and artificial lagoons as landscape tools that could enhance diversity in these agro-ecosystems.
Abstract (es):
La región de los Llanos, al oriente de Colombia, alberga una gran biodiversidad, pero al mismo tiempo está siendo blanco de fuertes procesos agroindustriales como el de la palma de aceite. Sin embargo, el conocimiento relacionado con la biodiversidad asociada a estos cultivos y su posible repercusión sobre la fauna silvestre nativa es mínimo. Por medio de fototrampeo se determinó la riqueza y frecuencia de captura de los mamíferos medianos y grandes asociados a una plantación de palma de aceite y sus ecosistemas naturales circundantes, en las sabanas inundables del departamento de Casanare, Colombia. Con un esfuerzo de muestreo de 3937 días/cámara se detectaron 16 especies de mamíferos medianos y grandes, y dos especies de ratones, cuyas frecuencias de captura variaron según el tipo de cobertura. Todas las especies estuvieron presentes en el bosque de galería; nueve de ellas estuvieron asociadas a palma y seis a sabana. Los mamíferos encontrados en la plantación fueron principalmente especies de mesodepredadores y generalistas, mientras que los de interior de bosque tienen dietas más restringidas. Se discute la importancia de los bosques de galería y las lagunas artificiales como herramientas de paisaje que mejorarían la diversidad en este tipo de agroecosistemas.
