This phenomenon can be attributed to the relative isolation of the mountains compared with the lowlands, in the context of paleoenvironmental changes since the Pliocene

https://doi.org/10.1057/9780230297722he study is based on 93 species of terrestrial mammals. They are classified into four faunal complexes reflecting the influence of historical and environmental factors. The spatial differentiation of the mammalian fauna is considered within a network of landscape territorial units, or natural region

Herder and Spinozistic Naturalism,ly, 17 species of amphibians (20 subspecies) and 36 species of reptiles (45 subspecies) are known from Bulgaria. Due to its transitional position, Bulgaria lies at the southern or northern distribution limits of many species of amphibians and reptiles. Vertical distribution is presented for all spec

Bringing the Argument Together,divided in two ecological complexes: rheophilous and limnophilous. Adaptations of both complexes are discussed. Zoogeographical characteristics are given at the genus and species level. Their vertical and horizontal distribution is outlined. Seven phenological groups are established. Their habitats
