Abstract

A comparative study of reproductive processes and habitats of northern and southern pop- ulations of Batrachyla taeniata was carried out in Chile. Differences in reproductive traits are related to climatic variability, particularly amount of rainfall and water availability. The most important difference is in the reproductive mode, namely that clutch and egg sizes are modified without changes in size of females. Batrachyla taeniata (Girard, 1854) occurs between 32?50'S to 45?25'S in Chile. In this wide range there are populations living in the cold rain forest of southern Chile (36050'S to 45?25'S) and also in the dry warm
