Book excerpt: This thesis investigates how the Bear River marsh0́9s protection became a national interest and a cause for conservation in the Progressive Era. The thesis documents how the marsh declined because of irrigation development culminating with an outbreak of avian botulism in 1910, and traces the long process to protect the marshland. The research focused on examining local water development patterns of the nineteenth and early twentieth centuries, ornithological research in the 1910s, and the national sportsmen0́9s conservation movement of the 1920s. Upon examination of these events, it becomes clear that a coalition of ornithologists, sportsmen, and policy makers worked together to institute change that affected the marsh. Through showing how groups came together in the past to work for conservation, this research highlights the important role that a coalition of groups can have in reshaping how a landscape is viewed and managed.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Bibliography of References to Avian Botulism written by Jack P. Allen and published by . This book was released on 1977 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography, first compiled in 1970 in response to many requests for information on avian botulism, has been updated to include the literature published through 1975. In general only, articles dealing primarily with the avian disease are included, as opposed to those concerned with the various aspects of the biology of Clostridium botulinum, either type C or type E.A few exceptions, such as Bengtson's report of the first isolation and description of the type C organism, are included for their historical interest. Progress reports and other administrative documents not available for distribution on request are excluded, as are textbook accounts, which are generally summaries of work published elsewhere. Although there was an attempt to list every important reference, no claim to complete coverage of the published literature is made and the authors will be grateful to users of the bibliography who call attention to errors or omissions.
