Book Description
Waterfowl in Winter was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. The emphasis in research on waterfowl has traditionally focused on breeding as opposed to migrant or wintering birds. Scientists have long been interested in courtship, nest sites, laying, and brood-rearing, and they have also been concerned about losses of eggs, young, nesting hens, and breeding habitats, especially as they have affected the goal of increasing populations. But lately there has been an upsurge of interest and research on the migratory and wintering phases, and this volume offers ample evidence of the knowledge gained. The authors—105 waterfowl biologists—have contributed 47 chapters that range geographically from Alaska to northern South America, and from the Pacific Northwest to Nova Scotia and Florida. Their subjects include: distributional changes due to human influence; population trends and concerns over less common species; pairing and other behavior that occurs in the wintering areas and is vital to the success of the species; feeding ecology and body condition during winter; new habitats created by such activities as aquaculture and park development; losses of habitat due to development and drainage for alternate uses; lead poisoning and pollutants that are detrimental to waterfowl; habitat management for maintenance of successful populations now and in the future. Also presented are reports of workshop discussions outlining current issues and future research needs. Preparation of this volume was assisted by an editorial board comprising Bruce J. J. Batt, Robert H. Chabreck, Leigh H. Fredrickson, and Dennis G. Raveling.
Eisler's Encyclopedia of Environmentally Hazardous Priority Chemicals

Book Description
Thousands of inorganic and organic chemicals and their metabolites enter the biosphere daily as a direct result of human activities. Many of these chemicals have serious consequences on sensitive species of natural resources, crops, livestock, and public health. The most hazardous of these were identified by a panel of environmental specialists from the U.S. Fish and Wildlife Service; these chemicals are the focus of this encyclopedia. For each priority group of chemicals, information is presented on sources, uses, physical and chemical properties, tissue concentrations in field collections and their significance, lethal and sublethal effects under controlled conditions. This includes effects on survival, growth, reproduction, metabolism, carcinogenicity, teratogenicity, and mutagenicity - and proposed regulatory criteria for the protection of sensitive natural resources, crops, livestock, and human health. Taxonomic groups of natural resources covered include terrestrial and aquatic plants and invertebrates, fishes, amphibians, reptiles, birds, and mammals. * The only product that centers on the most hazardous environmental chemicals to sensitive natural resources * The only single volume compendium on the subject, allowing ease in consulting * Written by a noted national and international authority on chemical risk assessment to living organisms
