Frog spatial distribution data (El Verde + Bisley)

Research Sites:

El Verde Research Area 9-ha plot Grid transect
Bisley Research Area Watershed 1 Grid points

Methods:

A 5m X 5m quadrant was established at certain grid points. Adult E. coqui were cohort marked by toc clip and measured with dial calipers to 0.5mm. Sex and reproductive condition were noted.

Abstract

Most Puerto Rican Eleutherodactylus are terrestrial frogs that breed for prolonged periods of time in more or less continuous habitat. Because their life cycle lacks a free living larvae stage, reproductive behavior is not tied to bodies of water and they do not have the large aggregations typical of many aquatic breeders. For these reasons, assessing their population status requires examining fairly large areas of habitat. I began systematically sampling the anuran community on a 12 ha grid at the Bisley watersheds in 1989 and a second 16 ha grid at El Verde in 1993. These efforts have provided a comprehensive data set that can be used to evaluate future changes in the anuran community in this forest.

Count of frogs, various frog predators, and various frog preys were taken at regular intervals on the grids.
