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.

This book was released on 2019-09-23 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the successful conclusion of the Joint Meeting of IUFRO’s 7.03.05 & 7.03.10 working parties and given the exciting and novel studies that have been presented in the framework of this meeting, we decided to present some of these studies in the current Special Issue of Forests. To make this issue more appealing and interesting to everyone in the field of Forest Protection, studies that cover a wide range of topics were selected, ranging from ecology and phylogeography to forest management and protection. More importantly, as these studies refer to pests and pathogens from different parts of the world, it is expected that the knowledge gained can be further used in the protection of natural environment worldwide.
Download or read book Warfare Ecology written by Gary E. Machlis and published by Springer Science & Business Media. This book was released on 2011-05-29 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is specific and ambitious: to outline the distinctive elements, scope, and usefulness of a new and emerging field of applied ecology named warfare ecology. Based on a NATO Advanced Research Workshop held on the island of Vieques, Puerto Rico, the book provides both a theoretical overview of this new field and case studies that range from mercury contamination during World War I in Slovenia to the ecosystem impacts of the Palestinian occupation, and from the bombing of coral reefs of Vieques to biodiversity loss due to violent conflicts in Africa. Warfare Ecology also includes reprints of several classical papers that set the stage for the new synthesis described by the authors. Written for environmental scientists, military and humanitarian relief professionals, conservation managers, and graduate students in a wide range of fields, Warfare Ecology is a major step forward in understanding the relationship between war and ecological systems.

Available in PDF, EPUB and Kindle. Book excerpt: In this lavishly illustrated volume, Richard E. McCabe, Bart W. O'Gara and Henry M. Reeves explore the fascinating relationship of pronghorn with people in early America, from prehistoric evidence through the Battle of Little Bighorn in 1876. The only one of fourteen pronghorn-like genera to survive the great extinction brought on by human migration into North America, the pronghorn has a long and unique history of interaction with humans on the continent, a history that until now has largely remained unwritten. With nearly 150 black-and-white photographs, 16 pages of color illustrations, plus original artwork by Daniel P. Metz, Prairie Ghost: Pronghorn and Human Interaction in Early America tells the intriguing story of humans and these elusive big game mammals in an informative and entertaining fashion that will appeal to historians, biologists, sportsmen and the general reader alike.
Download or read book Contemporary Environmental Issues and Challenges in Era of Climate Change written by Pooja Singh and published by Springer Nature. This book was released on 2019-11-16 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few decades, unprecedented global population growth has led to increased demand for food and shelter. At the same time, extraction of natural resources beyond the Earth’s resilience capacity has had a devastating effect on ecosystems and environmental health. Furthermore, climate change is having a significant impact in a number of areas, including the global hydrological cycle, ecosystem functioning, coastal vulnerability, forest ecology, food security, and agricultural sustainability. According to the Intergovernmental Panel on Climate Change (IPCC), only immediate and sustained action will prevent climate change causing irreversible and potentially catastrophic damage to our environment. This book presents various scientific views and concepts, research, reviews, and case studies on contemporary environmental issues in changing climate scenarios and highlights different adaptation measures. Increasing awareness of modern-day patterns of climate change, it addresses questions often raised by environmental scientists, researchers, policymakers and general readers.
Download or read book Landscape Genetics written by Niko Balkenhol and published by John Wiley & Sons. This book was released on 2015-11-09 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS Edited by Niko Balkenhol, Samuel A. Cushman, Andrew T. Storfer, Lisette P. Waits Landscape genetics is an exciting and rapidly growing field, melding methods and theory from landscape ecology and population genetics to address some of the most challenging and urgent ecological and evolutionary topics of our time. Landscape genetic approaches now enable researchers to study in detail how environmental complexity in space and time affect gene flow, genetic drift, and local adaptation. However, learning about the concepts and methods underlying the field remains challenging due to the highly interdisciplinary nature of the field, which relies on topics that have traditionally been treated separately in classes and textbooks. In this edited volume, some of the leading experts in landscape genetics provide the first comprehensive introduction to underlying concepts, commonly used methods, and current and future applications of landscape genetics. Consistent with the interdisciplinary nature of the field, the book includes textbook-like chapters that synthesize fundamental concepts and methods underlying landscape genetics (Part 1), chapters on advanced topics that deserve a more in-depth treatment (Part 2), and chapters illustrating the use of concepts and methods in empirical applications (Part 3). Aimed at beginning landscape geneticists and experienced researchers alike, this book will be helpful for all scientists and practitioners interested in learning, teaching, and applying landscape genetics.
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 Horns Pronghorns and Antlers written by George A. Bubenik and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first drawings left on walls of ancient caves, human beings have been fascinated with that unique phenomenon of the animal kingdom, the presence of horns and antlers. From the mythical ''unicorn'' exercising the power over life and death to the perceived aphrodisiacal and other medical properties of rhinoceros horns and growing antlers, these conspicuous protuberances have had a significant place in the history of mankind. Part of that ancient interest in antlers and horns was due to their value as sym bols of masculinity; this interest persists today in trophy hunting, an honorable tradition carried on for centuries in many countries of the world. This book, which deals with evolution, morphology, physiology, and behavior, has not been devised as a comprehensive review of the subject of horns, prong horns, and antlers; rather, it is a series of chapters stimulating thoughts, discus sions, and initiation of new studies. As editors, we did not interfere with the content of articles nor with the opin ions and interpretations of our contributors, and we left them to decide whether to accept the suggestions of our reviewers. Despite the fact that various aspects of cranial appendages have been studied since the end of the eighteenth century, many controversial views still exist, as witnessed in various chapters of this book.

Download or read book Endangered Species Threatened Convention written by Barnabas Dickson and published by Routledge. This book was released on 2013-11-05 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Convention on International Trade in Endangered Species (CITES) is the best known and most controversial of international conservation treaties. Since it came into force 25 years ago, debate has raged over its most basic assumptions. CITES treats the international trade in wildlife as the most important threat to the continued existence of wild species. It offers a prescription of trade bans and restrictions for endangered species. However, it is now generally acknowledged that for most species habitat loss is a much more significant threat. Some argue that the CITES remedy actually exacerbates the problem by removing the incentive to conserve wildlife habitat. This collection of essays, the first of its kind, charts the controversies and changes within CITES. It provides case studies of the way CITES has dealt with particular species and notes the growing role of the South in shaping the direction of the treaty. It considers the role of sustainable use, the precautionary principle and unilateralism within CITES. Finally, it examines options for the future of CITES. Implicit within a number of the contributions is the recognition that questions of wildlife conservation cannot be divorced from wider issues of land use, development and social justice. This book provides an essential resource for policy makers, practitioners, academics and students concerned with conservation, development and trade.
