Effects of agricultural systems on the anuran diversity in the Colombian amazon

AbstractWe provide information on the diversity of anurans from agroforestry systems in the Colombian Amazon. This area is inserted at the tropical rainforest ecosystem and consists mainly of secondary forest remnants surrounded by crops, grasslands, and agroforestry systems. From February to May 2015, we sampled anurans mainly with visual and auditory surveys. We recorded a total of 1096 individuals of 20 species of anurans from six families at the study area. The relictual forest was the richest environment, followed by Achapo and Cacao agroforestry systems. The Achapo system showed great similarity in species composition with relictual forest, however, the latter presented the highest number of exclusive species, whereas the first presented only two and Cacao system didn’t have any exclusive species. Our results show that the richness can vary between the different types of agroforestry systems and highlight their importance as management tool for anurans conservation in the Colombian Amazon.
