Alpine ibex, habitat, fragmentation

The habitat preference of Capra ibex was modeled by applying generalized linear models (GLMs) and ecological niche factor analyses (ENFA). To get an insight into the differences in habitat preferences in the Western and Eastern Alps, two study areas with GPS collared individuals were selected and the summer and winter season was modeled. Both areas show very similar habitat preferences during the winter season and it was also possible to successfully predict the winter habitat in the Eastern Alps using the GLM of the Western Alps. By contrast, in summer the habitat preferences of Capra ibex varied widely between the study areas. A comparison of the two modeling techniques showed that the overall results are highly comparable. Due to the big influence of the validation method used, it was not possible to make a general recommendation for one modeling method or the other. A new approach to validate habitat models without absence data is presented, using the correlation of Local Convex Hulls with HSI values of the models.
