Spatial Ecology of Desert Rodent Communities

by Georgy I. Shenbrot, Boris R. Krasnov, Konstantin A. Rogovin

Overview

Rodents are conspicuous and important components of the desert biome. Many general concepts in modern community and behavioral ecology use them as a main model.
This volume compiles and generalizes data on the spatial structure of desert rodent communities, taking into account both global (biogeographic) and local (ecological) patterns. It is based on studies of rodents in different deserts of the Northern Hemisphere (Karakum, Kyzylkum, Bet-Pak-Dala, Gobi, Thar, Chihuahua, Negev, and North Caspian deserts) as well as on a thorough analysis of the literature.
