Abstract:
Temporal variability of spawning site selection in the frog Rana dalmatina: consequences for habitat
management.— We evaluated whether R. dalmatina females laid their eggs randomly within a pond or
preferred particular microhabitats. The same measures were performed in the same area in two consecutive
years to determine whether the pattern remained constant over time. In 2003, we observed a significant
selection for areas with more submerged deadwood and vegetation, presence of emergent ground and low
water depth. However, these results were not confirmed in the subsequent year when none of the
microhabitat features measured had a significant effect. Although microhabitat features can strongly
influence tadpoles, the temporal variability of habitat at this spatial scale suggests that habitat management
could be more effective if focused on a a wider spatial scale.
