A methodological assessment of Species Distribution Models as tools to plan species conservation and niche modelling
Knowing species distribution is essential to understand a species’ ecology and conservation needs. Species distribution models (SDMs) adopt a correlative approach to infer the ecological requirements of species from field observations based on statistically or theoretically derived response surfaces...

Knowing species distribution is essential to understand a species’ ecology and conservation needs. Species distribution models (SDMs) adopt a correlative approach to infer the ecological requirements of species from field observations based on statistically or theoretically derived response surfaces. SDMs have become a widely used technique and an increasingly important tool in many fields of natural and biological sciences to address various issues in applied ecology and conservation biology. The most basic of such aims is to understand the relationships between a species and its abiotic and biotic environment and to identify areas where a given species is likely to occur. The aim of this thesis was to evaluate the effectiveness of SDMs for supporting conservation actions. In particular, we used SDMs to focus on important but less handled issues and present three case studies. In the first case, we analysed the influence of spatial scale on SDMs’ ability to detect niche differences for two sympatric species of high conservation value, the bat Barbastella barbastellus and the cerambycid beetle Rosalia alpina, which apparently share the same habitat and ecological requirements. Broad scale SDMs revealed limited differences in preferred environmental predictor variables while failed to detect differences in microhabitats occupied.
