Different bat guilds perceive their habitat in different ways: a multiscale landscape approach for variable selection in species distribution modelling

摘要: Context Unveiling the scale at which organisms respond to habitat features is crucial understand how they are influenced by anthropogenic environmental changes. We implemented species distribution models (SDMs) based on multiple-scale landscape pattern analysis for four bat representative of different foraging guilds: Nyctalus leisleri, Rhinolophus hipposideros, Myotis emarginatus and Pipistrellus pipistrellus. Objectives (a) assess factors influence suitability bats; (b) develop an objective methodology select best performing variables from a large variable dataset. Methods performed study in central Italy (Tuscany): 381 were derived topographical maps using moving windows set three spatial scales (1, 5 10 km) that ecologically meaningful bats.
