Abstract

In this paper we analysed the different types of distribution, or chorotypes, existing for the 70 species of micro-mammals distributed by the 12 mountain ranges surrounding the westernmost part of the Mediterranean basin. We also analysed the species richness’ trends in relation to the main environmental gradients. We identified five chorotypes involving the distributions of 49 species: a widespread chorotype (I), two Iberian chorotypes (II and III), an Alpine chorotype (IV), and an African chorotype (V). Only chorotypes II, IV, and V were environmentally characterised. Chorotype II corresponds to the mountain ranges with intermediate precipitation. Chorotype IV includes the range with the highest precipitation and climatic instability. Chorotype V involves the mountain ranges with highest energy availability. For non-rodents and for all micro-mammals together, the number of species shows a bimodal trend with respect to energy availability. For rodents this bimodal trend occurs mainly with respect to the simultaneous availability of water and energy.
