Landscape fragmentation and habitat suitability in endangered Italian hare (Lepus corsicanus) and European hare (Lepus europaeus) populations

摘要

During the last years, the population of Italian hare decreased significantly in central and south Italy. This is imputable to harvest, poaching, habitat fragmentation, and the probable competition with congeneric European hare introduced in the lastdecades by man for hunt. The goal of our work is to define the ecological characteristics of the two aforementioned species in order to understand how landscape facilitates or impedes movement. Spatially explicit models are used to identify a species ecological niche and to build a landscape model of suitability. To validate ecological modeling of landscape, we performed a population genetic analysis. Results suggest that the Italian hare shows an ecological requirement close to average of available resources in the considered landscape. The genetic structure of this autochthonous species validates the habitat suitability model and highlights the differences with European hare. This work analyzes for the first time the ecological relationship between those two sympatic species.
