Download or read book Age Distribution and Survival of Coyotes and Gray Foxes in Western Texas written by Cassie Ann Kirk and published by . This book was released on 2019 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coyote (Canis latrans) is one of the top predators in the state of Texas. They have been able to adapt to urbanization and continue to thrive in the wild. The coyote is also considered a top down keystone species. As such, coyote management can influence how other species are managed. Female coyotes can become sexually mature once they experience their first estrus cycle in the first year of life. Gray foxes (Urocyon cinereoargenteus) occur throughout Texas. Both male and female gray foxes can attain sexual maturity at an early age. Females on average breed for the first time at about 9-10 months of age. A better understanding of the age structure and survival rate of both species, we can better understand how many possible individuals we have that will be in prime breeding age, and how exploitation of the species may be effecting structure of the population. Given that both species are harvested in predator hunts and nuisance animal situations, I wanted to explore age structure and survival of coyotes and gray foxes in western Texas. I collected the lower canine tooth from 378 coyotes from the Panhandle and southwest areas of Texas. I also collected 288 lower canine teeth of gray fox samples from the Edwards Plateau and the Trans Pecos ecoregion. The teeth were processed for cementum annuli to access age for each individual. I then developed age distributions and used these distributions to calculate annual survival rates using a-structured regression. The overall survival of coyotes in Texas was 0.659. For females in total, annual survival was 0.709. Males annual survival was 0.686. The annual survival of all the gray foxes together is 0.650. Females annual survival was 0.647. Male's annual survival was 0.643. The coyote and gray fox are adaptive species and can survive in different habitats and situations. The age structure in both species does suggest that exploitation is changing the age structure towards a younger dominant composition. However, these age structures also suggest that all of the populations I examined have not been over-harvested. Shifting populations to younger age classes can reduce age at maturity and increases litter sizes. Thus, the demographic strategy of these species apparently allows them to be resilient to current exploitation levels in this region.
Download or read book The Mammals of Trans Pecos Texas written by Franklin D. Yancey and published by Texas A&M University Press. This book was released on 2023-12-14 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred and five species of mammals are native to the Trans-Pecos region of Texas. The greatly varied terrain, climate, and vegetation make its mammalian life exceptionally varied, ranging from tiny shrews to great elks, from bats to aquatic beavers and muskrats, from desert-dwelling kangaroo rats to forest-loving chipmunks, and from an assortment of mice and rats to predatory cougars and coyotes. This fully revised and updated edition of The Mammals of Trans-Pecos Texas provides a guide to the identification of these animals and summarizes important facts about their lives. With nearly every species illustrated with accurate, detailed pen-and-ink drawings by artist Chester O. Martin and color plates of some of the most iconic mammals that live in the Trans-Pecos region, it exemplifies how biologists integrate art with science to develop a wider appreciation for nature. The account of each species is arranged to contain a brief description of the animal, the geographic distribution of the species, and a discussion of the natural history of the mammal. This authoritative work brings together an appreciation for and understanding of the diversity of fauna, life histories, and ecologies within a unique and fascinating landscape.

Download or read book Rangeland Wildlife Ecology and Conservation written by Lance B. McNew and published by Springer Nature. This book was released on 2023-09-01 with total page 1017 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.

Book excerpt: The New York Times best-selling account of how coyotes--long the target of an extermination policy--spread to every corner of the United States Finalist for the PEN/E.O. Wilson Literary Science Writing Award "A masterly synthesis of scientific research and personal observation." -Wall Street Journal Legends don't come close to capturing the incredible story of the coyote. In the face of centuries of campaigns of annihilation employing gases, helicopters, and engineered epidemics, coyotes didn't just survive, they thrived, expanding across the continent from Alaska to New York. In the war between humans and coyotes, coyotes have won, hands-down. Coyote America is the illuminating five-million-year biography of this extraordinary animal, from its origins to its apotheosis. It is one of the great epics of our time.

Download or read book Pronghorn written by Bart W. O'Gara and published by . This book was released on 2004 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the fastest land animals on Earth (second only to the cheetah), the pronghorn can reach speeds of more than 50 miles per hour. It also is one of the most fascinating of all animals. For many people, the pronghorn was nearly as much a symbol of the American West as was the bison; for some, it still is. Eliminated from much of its historic range by the early 1900s, this unique North American big game species has experienced a remarkable recovery and now is found throughout the western United States, Canada, and northern Mexico. Thirty years in the making, Pronghorn: Ecology and Management contains the most comprehensive information on the behavior, physiology, migration, taxonomy, and management of this extraordinary animal. Full chapters are devoted to distribution, nutrition and food, diseases and parasites, ecosystem management, hunting, and much more. The principal authors--the world's preeminent pronghorn biologists, Bart W. O'Gara and Jim D. Yoakum--conclude with a thorough discussion of the future of pronghorn and their management. With 23 chapters that include contributions by 10 other wildlife professionals and more than 850 illustrations, including original artwork by Edson Fichter and Daniel P. Metz, Pronghorn: Ecology and Management is the definitive work on the species. A Wildlife Management Institute Book

Download or read book The North American Model of Wildlife Conservation written by Shane P. Mahoney and published by JHU Press. This book was released on 2019-09-10 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.
