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.

Spatial patterns of movement are fundamental to the ecology of animal populations, influencing their social organization, mating systems, demography, and the spatial distribution of prey and competitors. However, our ability to understand the causes and consequences of animal home range patterns has been limited by the descriptive nature of the statistical models used to analyze them. In Mechanistic Home Range Analysis, Paul Moorcroft and Mark Lewis develop a radically new framework for studying animal home range patterns based on the analysis of correlated random work models for individual movement behavior. They use this framework to develop a series of mechanistic home range models for carnivore populations. The authors' analysis illustrates how, in contrast to traditional statistical home range models that merely describe pattern, mechanistic home range models can be used to discover the underlying ecological determinants of home range patterns observed in populations, make accurate predictions about how spatial distributions of home ranges will change following environmental or demographic disturbance, and analyze the functional significance of the movement strategies of individuals that give rise to observed patterns of space use. By providing researchers and graduate students of ecology and wildlife biology with a more illuminating way to analyze animal movement, Mechanistic Home Range Analysis will be an indispensable reference for years to come.

Mammals of Africa (MoA) is a series of six volumes which describes, in detail, every currently recognized species of African land mammal. This is the first time that such extensive coverage has ever been attempted, and the volumes incorporate the very latest information and detailed discussion of the morphology, distribution, biology and evolution (including reference to fossil and molecular data) of Africa's mammals. With more than 1,160 species and 16-18 orders, Africa has the greatest diversity and abundance of mammals in the world. The reasons for this and the mechanisms behind their evolution are given special attention in the series. Each volume follows the same format, with detailed profiles of every species and higher taxa. The series includes hundreds of colour illustrations and pencil drawings by Jonathan Kingdon highlighting the morphology and behaviour of the species concerned, as well as line drawings of skulls and jaws by Jonathan Kingdon and Meredith Happold. Every species also includes a detailed distribution map. Edited by Jonathan Kingdon, David Happold, Tom Butynski, Mike Hoffmann, Meredith Happold and Jan Kalina, and written by more than 350 authors, all experts in their fields, Mammals of Africa is as comprehensive a compendium of current knowledge as is possible. Extensive references alert readers to more detailed information. Volume III, edited by David Happold, has profiles of 395 species of rodents, comprising the squirrels, dormice, jerboas, blind mole-rats, African root-rats, pouched rats and mice, Swamp Mouse, climbing mice, fat mice, White-tailed Rat, rock mice, voles, Maned Rat, spiny mice, brush-furred mice, gerbils, jirds, taterils, African Forest Mouse, rats and mice, vlei rats, whistling rats, anomalures, springhares, gundis, African mole-rats, porcupines, Noki (Dassie Rat), cane rats and Coypu. The volume concludes with 13 species of hares and rabbits.

My interest in the behaviour and movements of birds of arid and semi-arid ecosystems began when my wife, Sue Milton, and I were Roy Siegfried, Director, at that time, of the Percy approached by Prof. FitzPatrick Institute of African Ornithology, to set up a project to investigate granivory in the South African Karoo. Sue and I spent some time finding a suitable study site, setting up accommodations and an automatic weather station at Tierberg, in the southern Karoo near the village of Prince Albert, and planning projects. Among our first projects was a transect where we noted plant phe nology, measured seed densities on the soil surface, counted birds, observed ant activity, measured soil surface temperatures and col lected whatever climate data we could at 40 sites along a 200-km oval route. Along the way, we became interested in the marked presence and absence of birds at certain sites - abundant birds one day, and very few birds at the same site a month later. Subsequent counts along fixed transects through shrublands confirmed that a number of bird species were highly nomadic over short and long distances, locally and regionally, leading to speculation on how widespread these movements were in the arid ecosystems of the world.

Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.
