Using hierarchical spatial models to assess the occurrence of an island endemism: the case of Salamandra corsica

Ecological Processes

Table 2 Binomial generalized linear models results assessing the environmental variation between presence/absence sites. The model-averaged importance for the variables present in the 100 best models is shown. % models, percentage of candidate models where the variable was included
