Ecosystem services provided by amphibians and reptiles in Neotropical ecosystems

Abstract

Human welfare depends directly or indirectly on the services provided by ecosystems. Amphibians and reptiles represent a high proportion of global species diversity and include species that are widely distributed throughout the world and play a variety of roles that benefit humans. The aim of this study was to identify and describe the ecosystem services provided by amphibians and reptiles in Neotropical ecosystems to evaluate the contribution of these highly diverse groups to human welfare. We conducted a literature review of articles and books from databases and university libraries and collected data from 106 studies. Amphibians and reptiles contributed directly and indirectly to the four types of ecosystem services: provisioning, regulating, cultural, and supporting. Most available studies reported the use of direct services from reptiles and indirect services from amphibians. Although eight ecosystem services were identified, most studies focused on reptiles as seed dispersers and protein sources. Biological pest control and bioturbation were the most widely studied services obtained from amphibians. Further research are necessary to understand the ecological functions involving amphibians and reptiles and their importance in the provision of key ecosystem services for human well-being. © 2013 Copyright Taylor and Francis Group, LLC.
