An approach to identify and levels of nesting habitat selection: a cross-scale analysis of Goshawk preferences
Nest site selection may result from diverse agents that work on different spatial scales, and amultilevel analysis can offer a more realistic vision of the search image (proximate factors) and of the scale of nesting habitat selection by a species. Cross-scale analyses of nesting habitat preferences...
