This book was released on 2015 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sonoran desert is home to the Sonoran pronghorn (Antilocapra americana sonoriensis), an endangered species with populations once numbering in the thousands and now reduced to fewer than 300. Monitoring of the population is limited to biennial counts which provide abundance estimates, but do not provide information on other demographic parameters. Pronghorn are sensitive to stress from physical capture making them good candidates for using noninvasive genetic methods. Noninvasive genetic sampling has commonly been utilized in carnivores, but is less developed in ungulates. We designed and implemented a method combining noninvasive genetic sampling and capture-recapture (NGS-CR) methods to monitor Sonoran pronghorn. One weakness of fecal DNA analysis methods is the difficulty of aging individuals with noninvasive genetic samples. We developed a model using several measures of pellet morphology to reliably classify pellets from fawn versus yearling and fawn versus adult using five-fold cross validation. We used our method of NGS-CR to estimate abundance and apparent annual survival and assessed the accuracy and precision of our estimates using capture-recapture simulations. While the inference of our estimates were limited to the population using watering holes (drinkers), our results indicate this methodology provided reasonable and precise abundance estimates though biased slightly low. Combining this method with radio-telemetry data would further improve the accuracy of the population estimate. As the population continues to expand, this method allows managers to monitor trends in abundance and survival as an indicator of the population's trajectory, as opposed to current aerial survey methods, which provide abundance estimates, but are costly and do not provide information on survival or other demographic parameters.

Download or read book Wildlife Ecology and Management in Mexico written by Raul Valdez and published by Texas A&M University Press. This book was released on 2019-02-07 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico’s wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico’s wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.

Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.

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
