Students and environmental consultants working with gopher tortoises and other upland species will find this handbook indispensable.
Download or read book The Sonoran Desert Tortoise written by Thomas R. Van Devender and published by University of Arizona Press. This book was released on 2006-09-01 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Biology and Conservation of North American Tortoises written by David C. Rostal and published by JHU Press. This book was released on 2014-08-01 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive book ever published on North America's native tortoises. Tortoises, those unmistakable turtles, evolved from a lineage that split off from the familiar pond turtles roughly 100 million years ago. Over time, these plant-eating land turtles spread around the world, growing to an enormous size (depending on the species) and living so long that they have become the stuff of legends. By most accounts, they are indeed the longest-lived of the turtles, with good records suggesting individuals may live as long as 180 years (anecdotal records suggest that some reach ages of 200 years or more). Providing the first comprehensive treatment of North America’s tortoises, Biology and Conservation of North American Tortoises brings together leading experts to give an overview of tortoise morphology, taxonomy, systematics, paleontology, physiology, ecology, behavior, reproduction, diet, growth, health, and conservation. The contributors carefully combine their own expertise and observations with results from studies conducted by hundreds of other researchers. The result is a book that belongs in the library of every herpetologist. Contributors Gustavo Aguirre L. Linda J. Allison Matthew J. Aresco Roy C. Averill-Murray Joan E. Berish Kristin H.

This book was released on 2012-04-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for ecologists interested in capturing their understandings of how natural systems work in software – to help inform their work and communicate the consequences of proposed management plans. Historically, ecologists had to rely on the skills of trained computer programmers to modeling natural systems, but now a new generation of software is allowing ecologists to directly capture their understandings of systems in software. This book is a compilation of spatially explicit simulation models developed by ecologists and planners without any formal computer programming skills. Readers will be inspired to believe that they too can create similar models of the systems with which they are familiar.

Download or read book The Texas Tortoise written by Francis L. Rose and published by University of Oklahoma Press. This book was released on 2014-06-05 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remnants of an ancient lineage, tortoises date back to the Eocene. Among the five species remaining in North America, Texas tortoises are the smallest in size and inhabit some of the harshest arid environments known. They are also the most neglected by wildlife personnel. In The Texas Tortoise, biologists Francis L. Rose and Frank W. Judd draw on decades of research to offer the first comprehensive account of this fascinating but threatened species. The authors begin by explaining the relationship of the Texas tortoise to other species, fossil as well as extant. They delineate the Texas tortoise’s environment and describe what it eats, how the animal grows and reproduces, and how it behaves. Throughout, Rose and Judd write eloquently about the threats to the species’ survival, reflecting deep concern about its future protection. The authors also discuss Texas tortoises’ significance in supporting other species in their environment—southern Texas and northeastern Mexico—where their survival is threatened by habitat reduction and increasing road traffic. “If you see a tortoise on the roadway,” Rose and Judd admonish the reader, “move it to safety, and drive away as quickly as legally allowed.” It is in fact illegal to collect or possess a Texas tortoise. But for those who do, this book advises how to care for the animal. Tortoises have enjoyed a splendid and diverse history. That they did so well for so long is perplexing, the authors note, as the animals are slow and do not actively defend themselves against predators. The Texas Parks and Wildlife Department lists Texas tortoises as “threatened,” and Rose and Judd call on the federal government to do the same. Biologists, conservationists, and turtle enthusiasts alike will find this guide to Texas and other tortoises invaluable.
Download or read book The Codex of the Endangered Species Act Volume II written by John F. Organ and published by Rowman & Littlefield. This book was released on 2023-11-13 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Endangered Species Act of 1973 (ESA) is one of the most cherished and reviled laws ever passed. It mandates protection and preservation of all the nation’s species and biodiversity, whatever the cost. It has been a lightning rod for controversy and conflicts between industry/business and environmentalists. In this volume, leading Endangered Species Act experts interpret and propose legislative and administrative changes to prepare the ESA for future challenges. They explore regulations on avoiding harm to and producing benefits for species, cooperation between state and federal agencies, scientific analyses, and the necessary politics to enact their ideas. This is a call to action to chart an enlightened future for the Endangered Species Act that embraces the nation’s moral commitment of 50 years ago to address species extinction constructively, mindful of biodiversity, and as a fixture among the nation’s values and needs. The interconnected web of life includes all living species that depend on each other for survival, us among them. The stakes—our very future—are too high to ignore.
