The conversion of Amazonian forests to agricultural lands has a negative impact on biota, being anurans one of the most vulnerable groups in the face of changes in the environmental conditions of their habitats. Traditionally, the influence of this transformation on the anurofaunistic assemblages of agricultural and natural systems has been analyzed in terms of species richness and abundance (i.e. taxonomic diversity), without taking into account, in the face of the disturbance, how altered morphological, ecological and reproductive characteristics contain individuals and functional groups in the community (i.e. functional diversity). We aim to show the differences between anuran taxonomic diversity (TD) and functional diversity (FD) metrics in natural systems (primary forest) and agricultural lands (secondary forest and banana crops) at Kawsay Conservation Concession, in the southeastern Peruvian Amazon. Anurans were sampled in thirty 4 x 30 m transects per site, recording species´ richness and abundances, as well as ten functional features related to their biological and ecosystem roles. The decrease in functional richness in the secondary forest –linked to local traits reductions– shows differences in TD and FD trends, contrasting with the similarity between primary forests and secondary forests for the rest of the local diversity estimates. Likewise, in the banana crop the transformation of the forest has promoted a drastic loss of species and functional traits, resulting in the lowest levels of TD and FD. In summary, a triple loss of biodiversity (species, groups and functional characteristics) associated with agriculture in the Peruvian Amazon is reported for the first time, which can be partially masked by the richness and species turnover increase in secondary forests.
