Ecological features of a <em>Rana iberica</em> population inhabiting a human-altered ecosystem

Abstract

In this work, data are presented about spatial use and behaviour of Iberian brown frog (Rana iberica) during and after the breeding season in Pontevedra (north-western Spain). Field data were collected between November 2008 and February 2010 at a human-altered stream. The results suggest that there was a change in habitat use between the breeding and the non-breeding seasons. Rana iberica individuals concentrated in the upper part of the stream during the breeding season (November-March), moving to lower parts of the stream during late spring and summer. The estimated monthly frog abundance was inversely correlated to the recorded mean daily minimum temperatures.
