A massive decline of biodiversity is caused by land-use changes. Efforts must therefore
be made to better understand the factors that govern organismal distribution, especially
for countries where traditional management is about to be intensified such as in Romania.
We here document the spatial distribution of amphibians from a Romanian rural landscape
where land-use is still largely traditional. We related the occurrence of nine amphibian
species and species richness to measures of composition and configuration of the landscape
surrounding 54 ponds at three spatial scales: circular areas of 400, 600 and 800 m
radii. Busy roads most severely impacted single species and amphibian richness whereas
landscape composition measures, such as cover of urban areas, agricultural areas,
pastures, forests and wetlands were of little importance. We suggest that the relative
unimportance of landscape compositional measures on amphibians is a consequence of
the traditional management of these landscapes that keep the environmental conditions
favorable for most species. (C) 2010 Elsevier Ltd. All rights reserved.
