Abstract
The Mediterranean region possesses a rich diversity of salamanders, which also exhibit a high degree of ecological diversification. It is assumed that the presence of salamanders is dependent on the level of vegetation cover in terrestrial habitats, but the strength of this association is likely to vary among species. In this study, we investigated the patterns of habitat utilization for Mediterranean salamanders based on 589 records of 33 species. We tested the hypothesis that the association between salamander presence and vegetation density varies among genera or reproductive modes (i.e. terrestrial vs aquatic). The results show that vegetation cover has similar influences on terrestrial and aquatic groups but important differences are identified for lotic and lentic aquatic species. Our findings also indicate that the aquatic lotic, terrestrial, and small-body species deviate significantly from that expected from the background range of variation.
