Diseases of Wild Waterfowl
Author: Gary A. WobeserPublisher: Springer Science & Business Media
ISBN: 1461559510
Category : Science
Languages : en
Pages : 318
Book Description
Management of wild waterfowl has become increasingly intensive. Many birds now hatch in managed nesting cover or in artificial nesting structures, use man-made wetlands, and winter on crowded refuges while consuming a grain diet The water they use is often limited in supply and may contain residues from its many prior users. Unfortunately, intensified management often results in new problems, among which disease is important There are many similarities between the current form of management used for some waterfowl and that used in domestic animals. In both, the objective is to maintain a healthy, productive population. Dealing with health problems in waterfowl will benefit from combining the skills of veterinary medicine and wildlife ecology. Revisiting this book after 15 years allowed me to consider changes at the interface between the two disciplines. Veterinary medicine traditionally has been concerned with the individual and with treating sick animals, while the ecologist is concerned with populations and the manager has limited interest in treating sick birds. During this period there has been a marked increase in awareness among veterinarians that they have a responsibility in wildlife and conservation biology. Curricula of many veterinary colleges now include material on non-domestic animals and attempt to put disease in an ecological context. Also during this time, waterfowl managers have become more aware of disease as a factor in population biology and there are early attempts to put numbers to "disease" in models of continental waterfowl populations.

Book Description
Historically Canadians have considered themselves to be more or less free of racial prejudice. Although this conception has been challenged in recent years, it has not been completely dispelled. In Colour-Coded, Constance Backhouse illustrates the tenacious hold that white supremacy had on our legal system in the first half of this century, and underscores the damaging legacy of inequality that continues today. Backhouse presents detailed narratives of six court cases, each giving evidence of blatant racism created and enforced through law. The cases focus on Aboriginal, Inuit, Chinese-Canadian, and African-Canadian individuals, taking us from the criminal prosecution of traditional Aboriginal dance to the trial of members of the 'Ku Klux Klan of Kanada.' From thousands of possibilities, Backhouse has selected studies that constitute central moments in the legal history of race in Canada. Her selection also considers a wide range of legal forums, including administrative rulings by municipal councils, criminal trials before police magistrates, and criminal and civil cases heard by the highest courts in the provinces and by the Supreme Court of Canada. The extensive and detailed documentation presented here leaves no doubt that the Canadian legal system played a dominant role in creating and preserving racial discrimination. A central message of this book is that racism is deeply embedded in Canadian history despite Canada's reputation as a raceless society.
