"Spring on the Sonoran Desert can be a four-month-long spectacle of life and color. Within these well-written pages, Alcock exposes us to the plant and animal life of a land many regard as desolate. To Alcock, the desert has a constant evolutionary beauty he never seems to tire of. Alcock's approach to his subject is an elegant combination of science and literature. Only the desert itself, arrayed in its April apparel, can rival the beauty of this book." ÑArizona Highways "Deserts are not as bereft of life as they seem; their barren landscapes can support a remarkable variety of plant and animal life, though it may require a patient and skilled naturalist to reveal its mysteries. John Alcock is just such a naturalist. . . . Alcock provides delightful insights into how insects provision their developing young, how parasites find their victims and how flowers attract pollinators. A book of this kind allows its author, more accustomed to the rigours and constraints of writing academic papers and books, to relate revealing anecdotes and simply to express their fascinating for natural history. . . . Books such as this serve a vital function in bringing the mysteries of the desert to the attention of a wider public." ÑTimes Literary Supplement

One of the most recognizable animals of the Southwest, the desert tortoise (Gopherus agassizii) makes its home in both the Sonoran and Mohave Deserts, as well as in tropical areas to the south in Mexico. Called by Tohono O'odham people "komik'c-ed," or "shell with living thing inside," it is one of the few desert creatures kept as a domestic petÑas well as one of the most studied reptiles in the world. Most of our knowledge of desert tortoises comes from studies of Mohave Desert populations in California and Nevada. However, the ecology, physiology, and behavior of these northern populations are quite different from those of their southern, Sonoran Desert, and tropical cousins, which have been studied much less. Differences in climate and habitat have shaped the evolution of three races of desert tortoises as they have adapted to changes in heat, rainfall, and sources of food and shelter as the deserts developed in the last ten million years. This book presents the first comprehensive summary of the natural history, biology, and conservation of the Sonoran and Sinaloan desert tortoises, reviewing the current state of knowledge of these creatures with appropriate comparisons to Mohave tortoises. It condenses a vast amount of information on population ecology, activity, and behavior based on decades of studying tortoise populations in Arizona and Sonora, Mexico, and also includes important material on the care and protection of tortoises. Thirty-two contributors address such topics as tortoise fossil records, DNA analysis, and the mystery of secretive hatchlings and juveniles. Tortoise health is discussed in chapters on the care of captives, and original data are presented on the diets of wild and captive tortoises, the nutrient content of plant foods, and blood parameters of healthy tortoises. Coverage of conservation issues includes husbandry methods for captive tortoises, an overview of protective measures, and an evaluation of threats to tortoises from introduced grass and wildfires. A final chapter on cultural knowledge presents stories and songs from indigenous peoples and explores their understanding of tortoises. As the only comprehensive book on the desert tortoise, this volume gathers a vast amount of information for scientists, veterinarians, and resource managers while also remaining useful to general readers who keep desert tortoises as backyard pets. It will stand as an enduring reference on this endearing creature for years to come.

What could seem less inviting than summer in the desert? For most people, this prospect conjures up the image of relentless heat and parched earth; for biologist John Alcock, summer in Arizona's Sonoran Desert represents an opportunity to investigate the wide variety of life that flourishes in one of the most extreme environments in North America. "Only very special plants and animals can survive and reproduce in a place that may receive as little as six inches of rain in a year," observes Alcock, "a place where the temperature may rise above one hundred degrees each day for months on end." Yet he and other biologists have discovered here startling signs of life hidden in plain view under the summer sun: ¥ male digger bees compete to reach virgins underground during the early summer mating season; ¥ the round-tailed ground squirrel goes about its business, sounding alarm calls when danger threatens its kin; ¥ the big-jawed beetles Dendrobias mandibularis emerge in time to feast on saguaro fruits and to use their mandibles on rival males as well; ¥ Harris's hawks congregate in groups, showing their affinity for polyandry and communal hunting; ¥ robberflies mimic the appearance of the bees and wasps on which they prey; ¥ and peccaries reveal the adaptation of their reproductive cycle to the desert's seasonal rains. The book's 38 chapters introduce readers to these and other desert animals and plants, tracing the course of the season through activities as vibrant as mating rituals and as subtle as the gradual deterioration of a fallen saguaro cactus. Enhanced by the line drawings of Marilyn Hoff Stewart, Sonoran Desert Summer is both an account of how modern biology operates and a celebration of the beauty and diversity that can be found in even the most unpromising places.

After a long and successful career as a theatre director in Manhattan, fifty-something Claire Gray succumbed to a tempting offer to establish the theatre department at the new and very well funded Desert Arts College in Palm Springs. It has proven to be an exciting opportunity for Claire but now she's facing the end of her first academic year with a measure of melancholy. Not only is the spring production about to end but her student and clandestine lover, Tanner Griffin, is about to leave school for Hollywood. The person responsible - renowned producer Spencer Wallace - spotted Tanner in an earlier school stage production and signed him to a role in his next film, Photo Flash. Now with the closing performance of the spring production completed, the cast party at Claire's house promises to be a bittersweet affair. What Claire gets, however, is more than she bargained for when, in the middle of the very crowded affair, Spencer Wallace turns up dead in Claire's pool. To make it worse, Claire herself is one of the most probable suspects - with means, motive, and opportunity to have committed the deed. But Wallace is a man with a past and a reputation - and there are far more than a handful of people with better reasons to wish him harm. Now, with time running short, it falls to Claire to figure out who is really responsible before someone else gets away with the crime and leaves her holding the bag.

·Techniques for traversing desert terrain-by vehicle, by mountain bike, or on foot ·Strategies for comfort, safety, and survival in extreme conditions ·Selecting gear and equipment for this special environmentLike any desert aficionado, Bruce Grubbs is obsessed with water: how much to bring, how to carry it, how to conserve it, and how to find it in the backcountry. But desert exploration involves much more. Grubbs provides the knowledge and skills you need to move through this landscape with confidence.In addition to techniques for hiking and mountain biking special to desert conditions, Grubbs tells how to prepare your vehicle for remote desert roads and how to avoid getting stuck in sand or busting a tire. He discusses navigating in the desert, "dry camping" skills, and techniques for minimum impact on this starkly beautiful but fragile environment. There are tips for dealing with desert heat-and cold-and other challenges (sharp spiny plants and venomous snakes are easy to avoid with a little preparation and know-how). But just in case, Grubbs troubleshoots the worst-case scenarios. Throughout, he gives an understanding of desert climate and seasons, and the unique plants and creatures at home in it.
