The Sonoran Desert Tortoise
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 petas 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.

The Lessening Stream
Newcomers to Tucson know the Santa Cruz River as a dry bed that can become a rampaging flood after heavy rains. Yet until the late nineteenth century, the Santa Cruz was an active watercourse that served the region's agricultural needsuntil a burgeoning industrial society began to tap the river's underground flow.
The Lessening Stream reviews the changing human use of the Santa Cruz River and its aquifer from the earliest human presence in the valley to today. Michael Logan examines the social, cultural, and political history of the Santa Cruz Valley while interpreting the implications of various cultures' impacts on the river and speculating about the future of water in the region.
Logan traces river history through three erasarchaic, modern, and postmodernto capture the human history of the river from early Native American farmers through Spanish missionaries to Anglo settlers. He shows how humans first diverted its surface flow, then learned to pump its aquifer, and today fail to fully understand the river's place in the urban environment.
By telling the story of the meandering riverfrom its origin in southern Arizona through Mexico and the Tucson Basin to its terminus in farmland near PhoenixLogan links developments throughout the river valley so that a more complete picture of the river's history emerges. He also contemplates the future of the Santa Cruz by confronting the serious problems posed by groundwater pumping in Tucson and addressing the effects of the Central Arizona Project on the river valley.
Skillfully interweaving history with hydrology, geology, archaeology, and anthropology, The Lessening Stream makes an important contribution to the environmental history of southern Arizona. It reminds us that, because water will always be the focus for human activity in the desert, we desperately need a more complete understanding of its place in our lives.
Prehistoric Culture Change on the Colorado Plateau
One of the largest archaeological projects ever undertaken in North America, Peabody Coal Company's Black Mesa Archaeological Project conducted investigations in northeastern Arizona from 1967 to 1983. This mammoth undertaking recognized and recovered the remains of ephemeral camps, early agricultural sites, Puebloan villages, and ...
