Anuran captured in pitfall traps in three agrossystems in northwestern São Paulo State, Brazil

Abstract

Although it is generally assumed that agriculture negatively influences amphibian populations, few studies on the effects of agricultural cultivations on neotropical anuran have been conducted. As a contribution to the knowledge about anuran in agriculture, the present study sought to identify the anuran species present in three different agrossystems. We used data from anurans captured in pitfall traps initially proposed for a survey of harvestmen fauna in three agrossystems (corn, soybean, and rubber tree). Four anuran species found in the pitfall traps belong to two Families: Leptodactylidae: Leptodactulus fuscus and L. mystacinus; and Leiuperidae: Eupemphix nattereri and Physalaemus cuvieri. In corn plantation, four species and 30 individuals were captured; in rubber trees, four species and 11 individuals; and in soybeans plantation, tree species and eight individuals. Our results show that anurans are present in agrossystems, mainly the generalist anuran species.
