Mycological paper on a revision of British Gymnoscaceae
Phosphorus is an essential element for plant growth and its input has long been recognised as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologists, as well as for environmentalists, ecologists and agriculturalists concerned with sustainable land management and pollution. The book is also recommended to fisheries managers, fertilizer manufacturers and biologists working for water utilities.

This book continues to provide a comprehensive overview of equine behaviour and an outline of current advances in our understanding, as well as offering insights into contemporary and future challenges for improving horse welfare and safety. Completely updated and revised, a new, international, expert editorial team builds on Andrew Fraser's decades of work as an ethologist, veterinarian, historian, horseman, breeder, trainer, conservationist, and field scientist, sharing essential knowledge to improve horse behaviour and welfare. A range of international experts and key opinion leaders have updated this edition to include the effects of noise on the horse's welfare, husbandry and grazing management including the identification of harmful plants and issues of climate change. New illustrations and examples bring the book to life and further help to explain equine behaviour in a whole range of different situations, including road transport and horse safety during transport. The text covers key issues concerning equipment and the horse's mouth. It gives new insights into genetics, temperament and horse vocalisations and what these indicate. Welfare assessment models are outlined and the challenges presented in different equestrian sports debated. Difficult topics such as euthanasia are covered also. This classic text remains an essential resource for veterinarians, animal scientists, equine professionals and horse owners.

Bierce stellt in diesem Wörterbuch den Kanon der menschlichen Schwächen, der Vorurteile, Absurditäten und Gewohnheiten zusammen. Die spitzfindig-bösen ››Definitionen‹‹ der Wörter legen genau den Aspekt in ihnen frei, den das normale Bewusstsein heuchlerisch zu vertuschen versucht.

Pesticides continue to be a major means of controlling pests and diseases of crops and have made a major contribution to increasing the world’s food production. Despite the problem of developing pest and disease resistance to certain pesticides, and public concern about their indiscriminate use and side-effects, they are likely to remain the basis of integrated pest management programmes. However, as this book seeks to demonstrate, there is scope to improve both the safety and efficiency of crop protection methods. The emphasis of the book is on methods of assessment and on application techniques to particular categories of crops. Written by leading authorities from Europe and North America, the book provides detailed reviews of relevant topics. It is essential reading for all researchers, advanced students and professionals concerned with crop protection, whether from the disciplines of entomology, plant pathology, weed science or agricultural engineering.

Feed intake is the central issue in animal husbandry, being the key factor in determining health, welfare, environmental impact and productivity. With the focus on these issues, this book has been developed from the 5th Zodiac Symposium held in Wageningen in April 1998. The book reflects research conducted by observing natural behaviour, by investigating form-function relationships, physiology, metabolism and genetic make-up, and by offering choices of feed and environment. Information from studies on humans, wildlife and fish, as well as farm animals, is presented. It is divided into three parts:Natural Feeding, Feeding Modes, Preferences and BehaviourPhysiological Regulation of Feed Intake: Genetic, Metabolic, Hormonal and Neural RegulationsEnvironmental Factors and Feed Intake: Feeding Behaviour, Feed Choice and Feeding HabitsContributors include leading research workers from several European countries and Africa.

Phoma is a genus of fungi within the Coelomycetes. These fungi are commonly and frequently recovered in culture from all ecological situations, but are very difficult to identify. There has been a great need for a practical manual to aid such identification, and this book will fill that gap. It provides line drawings and keys for the identification of common pathogenic and saprotrophic species of Phoma in vitro, with references to additional diagnostic literature, representative cultures and documentation of the numerous synonyms formerly used in the mycological and phytopathological literature.
