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.

This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1964.

Desert Biology: Special Topics on the Physical and Biological Aspects on Arid Regions, Volume I covers the biology, geophysical characteristics, and ways of life in arid regions. This book is composed of 11 chapters, and begins with a brief description of a desert community, the Merkhiyat Jebels, with its diverse fauna and flora. The subsequent chapters look into the climate, geographical distribution, geologic and geomorphic aspects, and the evolution of desert community. These topics are followed by intensive discussions on desert plants, animals, and limnology. The last chapter describes the adaptive processes and human adaptation capacity to arid environments. This book will prove useful to upper division and graduate students in desert biology.

This report presents estimates of functional difficulties among school-aged children and adolescents in the United States. Using data from the National Health Interview Survey for 2001-2007, for children aged 4 to 17 years old, it provides information on difficulties related to sensory, motor, cognitive, and emotional or behavioral functioning, as well as educational and health care service use. Statistics are also included on association with family poverty, health insurance, ethnic background, and family structure.

Hippos, crocodiles and anacondas are just a few of the fascinating animals featured in their watery habitat.

A Desert Habitat describes one of the world's most fascinating desert habitats: the Sonoran Desert. Discover how animals find food, keep cool, and stay alive.

Meet animals that live in the desert, including camels, lizards, owls, snakes, spiders, and tortoises. Pair this photo-illustrated nonfiction title with its fiction companion book, No Bugs Here.
