Book excerpt: Desert invertebrates live in an environment where resources alternate unpredictably between brief periods of plenty and prolonged scarcity. This book describes the adaptive strategies of desert invertebrates in acquiring energy and sustaining life with such fluctuations. Some cooperate in foraging; others compete for resources. Some are nomadic and migrate to more favorable sites as conditions change. Others conserve energy by going into a deep dormancy until better conditions return. Still others store food during plentiful periods so as to retreat underground during less favorable times. The adaptive modes of economizing on scarce energy resources are diverse and lead to an appreciation of the intricate interactions of animals living close to their environmental limits.

Book Synopsis Biology of Desert Invertebrates by : C. S. Crawford

Download or read book Biology of Desert Invertebrates written by C. S. Crawford. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: What little we know of the biology of desert invertebrates stems largely from inferences based on intensive and repeated observations. Such informa tion is not gained easily, since despite the actual abundance of these animals, relatively few of them are ever seen. In fact, except for species impacting on the well-being of human populations, historically most have been ignored by scholars in the western world. Indeed, it was ancient Egypt, with its reverence for the symbolism of the scarab, that probably provided us with the clearest early record of prominent desert types. A more modest resurgence of the story had to wait until the arrival of the present century. To be sure, some of the more obvious species had by then been elevated by European collectors to the level of drawing-room curios ities, and expeditions had returned large numbers to museums. But by 1900 the task of describing desert species and relationships among them was still in its infancy; and as for careful natural history studies, they too were just coming into their own.

Book Synopsis Encyclopedia of Deserts by : Michael A. Mares

Download or read book Encyclopedia of Deserts written by Michael A. Mares. This book was released on 2017-01-19. Available in PDF, EPUB and Kindle. Book excerpt: Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.

Book Synopsis Invertebrates in Hot and Cold Arid Environments by : Lauritz Somme

Download or read book Invertebrates in Hot and Cold Arid Environments written by Lauritz Somme. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: A comparison of the adaptations made by invertebrates in polar deserts with those of temperate and subtropical deserts. These regions represent some of the most hostile environments on earth, demanding an array of strategies for survival. Polar species are well adapted to the cold and have to cope with arid conditions due to low precipitation and lack of liquid water during the winter. Similarly, temperate desert invertebrates have adapted to dry conditions and are also exposed to low winter temperatures. Terrestrial arthropods maintain their water-balance through behavioural and physiological adaptations. Tardigrades and nematodes are remarkable in their ability to shed all their water before entering a state of anhydrobiosis only to be revived when moisture once again becomes available.
