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.

Zoonotic diseases constitute a public health problem throughout the world. Addressing a little studied area of veterinary and medical science, this book covers the viruses, bacteria and protozoan and helminth parasites that are transmitted between man and dogs, discussing population management, control disease agents and human-dog relationships. Fully updated throughout, this new edition also includes two new chapters on benefits of the human-dog relationship and non-infectious disease issues with dogs. It is a valuable resource for researchers and students of veterinary and human medicine, microbiology, parasitology and public health.

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.

The new Equid Action Plan provides current knowledge on the biology, ecology and conservation status of wild zebras, asses, and horses. It specifies what information is lacking, and prioritizes needed conservation actions. The Action Plan also provides chapters on equid taxonomy, genetics, reproductive biology, and population dynamics. These chapters highlight unsolved issues of taxonomy and genetics. They also provide information and insight into the special demographic and genetic challenges of managing small populations. The chapter on disease provides a review of documented equine disease and epidemiology and focuses on priorities for equid conservation health. The final chapter deals with the importance of developing an assessment methodology that explicitly considers the role of equids in ecosystems and the ecological processes that are necessary for ecosystem viability. The approach of combining ecological field studies and ecosystem modeling should prove useful for the scientific management and conservation of wild equids worldwide. These chapters provide research and conservation practitioners with new information and paradigms.

In Contraception and Abortion from the Ancient World to the Renaissance, John M. Riddle showed, through extraordinary scholarly sleuthing, that women from ancient Egyptian times to the fifteenth century had relied on an extensive pharmacopoeia of herbal abortifacients and contraceptives to regulate fertility. In Eve’s Herbs, Riddle explores a new question: If women once had access to effective means of birth control, why was this knowledge lost to them in modern times? Beginning with the testimony of a young woman brought before the Inquisition in France in 1320, Riddle asks what women knew about regulating fertility with herbs and shows how the new intellectual, religious, and legal climate of the early modern period tended to cast suspicion on women who employed “secret knowledge” to terminate or prevent pregnancy. Knowledge of the menstrual-regulating qualities of rue, pennyroyal, and other herbs was widespread through succeeding centuries among herbalists, apothecaries, doctors, and laywomen themselves, even as theologians and legal scholars began advancing the idea that the fetus was fully human from the moment of conception. Drawing on previously unavailable material, Riddle reaches a startling conclusion: while it did not persist in a form that was available to most women, ancient knowledge about herbs was not lost in modern times but survived in coded form. Persecuted as “witchcraft” in centuries past and prosecuted as a crime in our own time, the control of fertility by “Eve’s herbs” has been practiced by Western women since ancient times.
