Book Description
Proceedings of the final research co-ordination meeting organized by the IAEA and the Direzione Generale per la Cooperazione Italiana allo Sviluppo, Rabat, Morocco, 23-27 March 1987. The production of meat, milk, wool and other products from grazing animals has a long and important tradition in countries around the Mediterranean and North Africa. Although there are many millions of both large and small ruminants in these countries, the output of livestock products is increasingly falling short of the demand created by human population expansion. To reverse, or at least slow down, this trend requires that better use be made of existing animal and feed resources - in effect to optimize individual productivity. The strategies to be adopted to optimize productivity need to be developed through both basic and applied research on breeding, feeding and other management practices. Nuclear techniques, employed in conjunction with standard methods, play an important role in developing a proper understanding of animal/environment interactions; they can also be used to examine how such interactions can be manipulated to minimize the impact of constraints and thereby to improve productivity.

Book Description
In this book, the late Richard Redding synthesizes his decades-long work on the ancient agricultural economy of Egypt. Drawing on a diverse range of data, including zooarchaeology, ancient texts, and iconographic sources, he explores the role of cattle, sheep, goats, and pigs in the economic infrastructure of ancient, mainly Pharaonic, Egypt and the complexities of decision-making processes that shaped the use and management of these vital livestock resources. The book integrates zooarchaeological and historical data with information on unimproved breeds of cattle, sheep, goats, and pigs from Egypt and the broader Middle East as well as considers texts and tomb paintings. Redding argues that understanding the interplay between economic forces, environmental factors, and herders' knowledge of animal characteristics is crucial for unraveling the dynamic nature of decision-making. The author explores herd growth rates, meat yields, caloric and nutritional benefits, and optimal herd structures. By employing that data and ecological models, including the annual Nile floods, he provides insights into the adaptive strategies employed by ancient Egyptian herders. In this way, Redding examines the economic rationale behind ancient Egyptian herding communities. His models of Pharaonic herding strategies generate expectations tested using zooarchaeological evidence. Redding long advocated the modeling approach he demonstrates here, understanding zooarchaeological data through a lens of animal biology and environmental context. This work should therefore spark wide interest among archaeologists working in disparate regions.

Book Description
Once plentiful in the mountains of southern Arizona, by the 1990s desert bighorn sheep were wiped out in the Pusch Ridge Wilderness of the Santa Catalina Mountains as a result of habitat loss and alteration. This book uses their history and population decline as a case study in human alteration of wildlife habitat. When human encroachment had driven the herd to extinction, wildlife managers launched a major and controversial effort to reestablish this population. For more than forty years Paul R. Krausman directed studies of the Pusch Wilderness population of these iconic animals, located in the mountainous outskirts of Tucson. The story he tells here reveals the complex relationships between politics and biology in wildlife conservation. His account of the evolution of wildlife conservation practices includes discussions of techniques and of human attitudes toward predators, fire, and their management.

Book Description
Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 15-19 April 1991. The symposium reviewed advances in nutrition and reproduction of ruminant and other herbivorous animals, as well as in new approaches to disease diagnosis and control. Consideration was given to isotope and related techniques currently employed in research, but more importantly to the application of research findings in improving the productivity of livestock reared in tropical and subtropical developing countries, e.g. of ruminant animals whose diets mainly consist of poor quality roughages. Also addressed were advances in the development of highly sensitive radioimmunoassay methods for measuring the concentrations of reproductive and other hormones. In addition, emphasis was given to developments in the use of enzyme linked immunosorbent assays, not only for diagnosis of diseases of major relevance to developing countries, but also for their applicability in monitoring the effectiveness of large scale vaccination programmes and conducting epidemiological surveys.
