Book Description
Pen-rearing young frequently fails as a reintroduction technique in game birds due to low post-release survival rates in the wild. This may be caused by a combination of poor genetics from domestication, unhealthy birds, birds that do not exhibit wild behavior, or birds that are unfamiliar with their surroundings after hard releases. Recent research suggests that parent-rearing, involving pre- and post-hatch imprinting of “wild-strain” northern bobwhite (Colinus virginianus) chicks by adults, may be a viable option for restoring populations. Imprinting potentially causes reintroduced birds to exhibit more natural behavior. I tested this method against a slightly modified traditional propagation tool (Surrogators) with “wild-strain” birds. I conducted my research on a 170 ha property containing a mixture of early successional and hardwood habitat on Long Island, New York during the summers of 2013 and 2014. I tested the effect of rearing methodology, mass at release (as a proxy for physical condition), release timing, and year on survival using Cox proportional hazard models. Hazard analysis revealed that only earlier release dates directly improved survival while treatment (parent-reared vs. Surrogator), body mass at release, and year did not affect survival. The methods tested on my study area did not result in 365 day survival rates high enough to re-establish quail in the area.

Book Description
Comprehensively explains animal learning theories and current best practices in animal training within zoos This accessible, up-to-date book on animal training in a zoo/aquaria context provides a unified approach to zoo animal learning, bringing together the art and science of animal training. Written by experts in academia and working zoos, it incorporates the latest information from the scientific community along with current best practice, demystifying the complexities of training zoo animals. In doing so, it teaches readers how to effectively train animals and to fully understand the consequences of their actions. Zoo Animal Learning and Training starts with an overview of animal learning theory. It describes the main categories of animal learning styles; considers the diverse natural history of zoo animals; reviews the research undertaken which demonstrates ultimate benefits of learning; and highlights the advantages and disadvantages of the different approaches. It also shows how the direct application of learning theory can be integrated into zoo animal management; discusses how other factors might affect development; and investigates situations and activities from which animals learn. It also explores the theoretical basis that determines whether enrichments are successful. Provides an easily accessibly, jargon-free introduction to the subject Explores different training styles, providing theoretical background to animal learning theory as well as considerations for practical training programme – including how to set them up, manage people and animals within them and their consequences Includes effective skills and ‘rules of thumb’ from professional animal trainers Offers commentary on the ethical and welfare implications of training in zoos Features contributions from global experts in academia and the zoo profession Uniquely features both academic and professional perspectives Zoo Animal Learning and Training is an important book for students, academics and professionals. Suited to senior undergraduate students in zoo biology, veterinary science, and psychology, and for post-graduate students in animal management, behaviour and conservation, as well as zoo biology. It is also beneficial to those working professionally in zoos and aquaria at different levels.

Book Description
Past progress and future challenges R.J. Wheater Royal Zoological Society of Scotland, Edinburgh, UK. In the past two decades much has been achieved in the sphere of breeding endangered species, and we should be pleased that our co operative efforts have already borne so much fruit. However, on balance and despite the best efforts of conservationists, the position of wildlife in the wild places where they are best conserved has become worse, often dramatically worse. Before returning to the United Kingdom in 1972, I was in Uganda for 16 years, most of which time was spent as Chief Warden of Murchison Falls National Park. Our main problem was that an over-population of large mammals was having a devastating impact on the habitat. Devas tation was being wrought on woodland areas by the arrival of large numbers of elephants into the sanctuary of the Park, following changes in land use in the areas outside the Park. These changes were in response to the requirements of an ever-expanding human population.

Book Description
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Book Description
This book aims to further advance the field of reintroduction biology beyond the considerable progress made since the formation of the IUCN/SSC Re-introduction Specialist Group. Using an issue-based framework that purposely avoids a structure based on case studies the book's central theme is advocating a strategic approach to reintroduction where all actions are guided by explicit theoretical frameworks based on clearly defined objectives. Issues covered include husbandry and intensive management, monitoring, and genetic and health management. Although taxonomically neutral there is a recognised dominance of bird and mammal studies that reflects the published research in this field. The structure and content are designed for use by people wanting to bridge the research-management gap, such as conservation managers wanting to expand their thinking about reintroduction-related decisions, or researchers who seek to make useful applied contributions to reintroduction.

Book Description
This book presents the results and conclusions of the longest continuous study ever undertaken for a local North American game bird population. Since 1950 abundance has been determined seasonally by direct count, nesting ecology by field searches and observation, and hunting pressure and harvest by field interviews. Land use and weather conditions also have been recorded. The period of the study saw considerable change in regional land use and included several of the most severe winters in recorded weather history. Continuing harvest of the study population did not have a progressively depressing effect on standing densities; rather it held breeding stock somewhat below K at a more productive point on the growth curve. Roseberry and Klimstra report that there was clear evidence of an 8 to 10-year cycle within the study population. They found after examining a number of cycle theories that a close temporal relationship existed between their bobwhite data and the nodal lunar cycle described by Archibald (1977). Sound field techniques, long-term data acquisition, and appropriate mathematical and statistical treatment of the data combine to provide a significant contribution to what is known of not only bobwhite but basic population ecology.

Book Description
"This is the second issue in the Global Re-introduction Perspectives series and has been produced in the same standardized format as the previous one. The case-studies are arranged in the following order: Introduction, Goals, Success Indicators, Project Summary, Major Difficulties Faced, Major Lessons Learned, Success of Project with reasons for success or failure. For this second issue we received a total of 72 case-studies compared to 62 in the last issue. These case studies cover the following taxa as follows: invertebrates (9), fish (6), amphibians (5), reptiles (7), birds (13), mammals (20) and plants (12) ... We hope the information presented in this book will provide a broad global perspective on challenges facing re-introduction projects trying to restore biodiversity."--Pritpal S. Soorae.
