Popis Classification of world’s biota into biogeographical regions is one of the main aims in the field of biogeography, however, issues concerning spatial properties of biogeographical regionalisations have been somewhat neglected to date. Here, I address following questions: Are mammalian and avian regions statistically delineated on the basis of assemblage distinctiveness spatially coherent across two spatial scales, i.e. in the perspective of western-central Europe (with grid resolution 50 × 50 km) and in national perspective of the Czech Republic (with grid resolution 11.1 × 12 km)? Which factors shape spatial pattern of biogeographical regions at these different scales? At broader scale of western-central Europe, both mammalian and avian regions were highly spatially coherent, whereas, at finer spatial scale of the Czech Republic, regions disintegrated into spatially discontinuous patches. Analysis of these spatial patterns revealed that, at broader scale, membership of grid cells in particular cluster may be explained by their geographical distance, whereas, at finer spatial scale, spatial pattern of delineated regions may be ascribed rather to environmental similarity.
