Book Description
The rapid increase in animal-vehicle collisions on U.S. roadways is a growing concern in terms of human safety, property damage and injury costs, and viability of wildlife populations. Wildlife crossing structures are gaining national recognition by transportation agencies as effective measures to reduce animal-vehicle collisions and connect wildlife habitats across transportation corridors. In Virginia, white-tailed deer and black bear pose the highest risk. This 1-year study was conducted to monitor various underpass structures in Virginia to determine the structural and location attributes that make a crossing successful in terms of use by large mammals. The underpasses, most of which were not specifically designed as wildlife crossings, consist of box culverts and bridges of varying sizes. Remote cameras installed at seven underpass sites in Virginia have recorded more than 2,700 wildlife photographs and documented 1,107 white-tailed deer crossings in the most heavily used structures. Underpasses with a minimum height of 12 ft were successful at facilitating deer passage. Such structures were also heavily used by a variety of wildlife species, including coyote, red fox, raccoon, groundhog, and opossum. Structures with drainages that mimic natural waterways can encourage use by a diversity of terrestrial, semi-aquatic, and aquatic species. This report provides guidance in choosing cost-effective underpass design and location features that are necessary to consider to increase motorist safety and habitat connectivity. The findings also demonstrate that if only a minimal number of deer-vehicle collisions is prevented by an effective underpass, the savings in property damage alone can outweigh the construction costs of the structure

Book Description
Animal-vehicle collisions (AVCs) have a growing impact in the United States in terms of safety, economic loss, and species conservation. According to estimates from insurance claims, Virginia has consistently ranked as one of the top seven states for deer-vehicle collisions (DVCs) since 2002. Of the state's estimated 43,500 to 47,700 DVCs in 2006, less than 14% were reported to the police and stored in the Virginia Department of Transportation's (VDOT) accident database. Virginia has no standardized method of sufficiently tracking AVC occurrences and locations, creating difficulty in researching and implementing mitigation efforts to reduce accidents. Valuable AVC data can be obtained from documenting the instances and locations of animal carcasses from the roadway, but most transportation organizations do not systematically record these removals. This project entailed testing a personal data assistant (PDA) enabled with a global positioning system (GPS) receiver for the collection and analyses of animal carcass removals (CRs) from the roadway. Using GPS-enabled PDAs and software developed by Western Transportation Institute, maintenance personnel from a VDOT area headquarters in Rockbridge County collected 8 months of spatially accurate CR data. Rockbridge County DVC estimates derived from the CR data collected for this study were more than 9 times greater than the number of AVCs reported in police records. These spatial data can be easily used for density analyses to determine "hotspots" of AVCs. Implementing mitigation at these areas can ultimately lead to fewer AVCs and associated reductions of human deaths, injuries, and financial losses; improved traffic operations; a reduction in maintenance costs related to carcass removal and disposal; and wildlife conservation. VDOT is currently undergoing changes to its method of documenting roadway maintenance activities, including the deployment of GPS-enabled PDAs to all area headquarters. These PDAs provide a mechanism for collecting spatially accurate and standardized CR data, but collecting and reporting CRs are currently not requirements. Given the PDA's ease of use and the benefits these data would provide, the study recommends that this procedure be integrated into regular practice by VDOT area headquarters. As VDOT is receiving added regulatory pressure to implement measures to reduce AVCs, improving CR data collection using the technology described in this report can help provide an objective method for deciding whether and where mitigation is needed.

Book Description
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.

Book Description
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.

Book Description
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bile bear market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.

Book Description
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.

Book Description
This edited volume presents original scientific research and knowledge synthesis covering the past, present, and potential future fire ecology of major US forest types, with implications for forest management in a changing climate. The editors and authors highlight broad patterns among ecoregions and forest types, as well as detailed information for individual ecoregions, for fire frequencies and severities, fire effects on tree mortality and regeneration, and levels of fire-dependency by plant and animal communities. The foreword addresses emerging ecological and fire management challenges for forests, in relation to sustainable development goals as highlighted in recent government reports. An introductory chapter highlights patterns of variation in frequencies, severities, scales, and spatial patterns of fire across ecoregions and among forested ecosystems across the US in relation to climate, fuels, topography and soils, ignition sources (lightning or anthropogenic), and vegetation. Separate chapters by respected experts delve into the fire ecology of major forest types within US ecoregions, with a focus on the level of plant and animal fire-dependency, and the role of fire in maintaining forest composition and structure. The regional chapters also include discussion of historic natural (lightning-ignited) and anthropogenic (Native American; settlers) fire regimes, current fire regimes as influenced by recent decades of fire suppression and land use history, and fire management in relation to ecosystem integrity and restoration, wildfire threat, and climate change. The summary chapter combines the major points of each chapter, in a synthesis of US-wide fire ecology and forest management into the future. This book provides current, organized, readily accessible information for the conservation community, land managers, scientists, students and educators, and others interested in how fire behavior and effects on structure and composition differ among ecoregions and forest types, and what that means for forest management today and in the future.
