Book Description
This collection of essays is the first major work in more than a decade to discuss the critical issue of wildlife contraception and the first ever to take up contraception-both theory and practice-for wild animals in captivity. The authors, leading international experts on the subject, analyze the use of wildlife contraception for various animal populations, including nonhuman primates, ungulates, pinnipeds, cetaceans, and other mammals. The chapters examine and critique types of contraception, and their effects, and explore the best method for each situation. Using the most recent data and findings, this comprehensive collection addresses problems related to unrestricted population growth, the ethics of wildlife contraception, and regulatory issues for wildlife managers, animal rights organizations, zoos worldwide, and anyone interested in the humane control of animal populations.

Book Description
This volume presents the first comprehensive look at fertility control in wildlife. It also has historical interest, because these essays are among the first to reveal some of the problems associated with hormonal contraception.

Book Description
This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences. Understanding reproductive biology is centrally important to the way many of the world’s conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world’s fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 – 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.

Book Description
Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Book Description
As a follow-up to the 2013 report Using Science to Improve the Wild Horse and Burro Program: A Way Forward, this letter report reviews research project proposals submitted to the Bureau of Land Management and aimed at developing new or refining existing techniques and establishing protocols for the contraception or permanent sterilization of either male or female wild horses and/or burros in the field. Review of Proposals to the Bureau of Land Management on Wild Horse and Burro Sterilization or Contraception considers factors related to the scientific validity of the proposed technique(s), goals and objectives of the work, research methodology and design of the study, proposed statistical analysis and interpretation of anticipated data obtained, animal welfare implications and Institutional Animal Care and Use Committee approvals, feasibility, as well as the qualifications, expertise, and experience of the investigators. This report ranks the proposals in order of merit and provides a brief report on additional factors for the Bureau of Land Management to consider in selecting proposals to fund.

Book Description
The determination of when, how, how often and with whom an animal breeds has moved away from evolutionary pressures towards our own purposes: these include the breeding and use of around 50 billion mammals and birds for food production annually, the breeding of pedigree dogs, cats, racing dogs and horses, specialized laboratory animal strains and the use of reproductive science to breed endangered species in zoos and to attempt to limit unwanted populations of pests and non-native species. This book discusses the methods, the motivations and the consequences of human intervention in animal breeding in terms of what we know about animal behavior and well-being. It sets out to challenge both our practice and our assumptions- those of society as a whole and the many professionals involved in the worldwide animal reproduction business. It explores where we are now and proposes a future where we have more respect for animals as sentient beings and have loosened the reins of reproductive control.
