Download or read book Habitat Use and Nesting Success of Dabbling Ducks in Western New York Grasslands written by Bridgett L. Estel and published by . This book was released on 1989 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted in western New York during the 1987 and 1988 waterfowl breeding seasons to identify locally nesting dabbling duck species, document key nesting habitats, and estimate nest success rates (NSR). Data were collected within a 7,963 ha area on the Iroquois National Wildlife Refuge and state- owned Oak Orchard and Tonawanda Wildlife Management Areas. Systematic nest searches were done in 4 grassland cover types: planted grassland, naturally seeded grassland, reverted cropland, and rights-of-way. The mallard (Anas platyrhynchos)and blue-winged teal (A. discors) were the predominant nesting species, comprising 39% and 53% respectively of the 338 nests found in grasslands. The overall nest success rate for mallards was .09 and the NSR for blue-winged teal averaged .21. Mallard nesting attempts were most successful in planted grassland (NSR = .28) and naturally seeded grassland (.11) and least successful in rights-of-way (1%) and reverted cropland (3%). Planted grasslands.
Download or read book Survival and Habitat Use of Mallard Broods in Western New York written by Andrew Peter Weik and published by . This book was released on 1994 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recruitment of waterfowl into the breeding population is a function of nesting success and duckling survival. Nesting success of mallards throughout their North American range has been well studied and estimates of duckling survival exist for mallards breeding in California, the northcentral U.S. and the prairie- parkland region of North Amercia; however, there have been no reliable estimates of duckling survival for mallards breeding in eastern North America. Survival, sources of mortality, movements and habitat use of mallard broods were studied at Iroquois National Wildlife Refuge and Tonawanda Wildlife Management Area in western New York during 1991-92. Hens were captured on nests during incubation and fitted with radio transmitters;ducklings were radio-marked before they left the nest.

Available in PDF, EPUB and Kindle. Book excerpt: In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension
