Four cases of prey-predator interaction (anuran-snake) through their geographical distribution

The biotic interaction prey-predator between one anuran species and one snake species, in some cases have been reported just in one geographical location, and in other cases have been reported several records through the geographical distribution of both interacting species. In this study we report four cases of anurans predation by snakes in different geographical location to the previous records. The previous and new records suggest that the biological interaction prey-predator between two species is maintained regardless of the geographical location and elevation. The consequences of these kind of biotic interactions for the predator and prey requires further study.
