Available in PDF, EPUB and Kindle. Book excerpt: The Queen Maud Gulf Migratory Bird Sanctuary in Nunavut, in the central Canadian Arctic, is an important breeding area for a variety of species of waterfowl and other wildlife. An assessment of the types and spatial extent of land cover, with a particular emphasis upon wildlife habitat capability, has not been available for this sanctuary, preventing an adequate environmental assessment of proposed changes to the sanctuary's boundaries and limiting attempts to evaluate population trends and the distribution of wildlife species within the sanctuary. LANDSAT Thematic Mapper satellite imagery and digital image processing technology were used to prepare a land cover map for this large and remote area. Data from an examination of a variety of possible image enhancements, three field seasons of ground and aerial inspections of land cover types, and image classification were used to generate a thematic map of land cover types. An accuracy assessment of the classification provided an estimate of the reliability of the land cover map.

Download or read book Coastal Wetlands written by Gerardo M.E. Perillo and published by Elsevier. This book was released on 2009-01-18 with total page 975 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world.

Book excerpt: Coastal Wetlands, Second Edition: An Integrated and Ecosystem Approach provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide. As coastal wetlands are under a great deal of pressure from the dual forces of rising sea levels and the intervention of human populations, both along the estuary and in the river catchment, this book covers important issues, such as the destruction or degradation of wetlands from land reclamation and infrastructures, impacts from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. Covers climate change and its influence on coastal wetland form and function Provides a fully updated and expanded resource, including new chapters on modeling, management and the impact of climate change Contains full-color figures of wetlands and estuaries in different parts of the world
Download or read book Birds of Nunavut written by James M. Richards and published by UBC Press. This book was released on 2018-08-10 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nunavut is a land of islands, encompassing some of the most remote places on Earth. It is also home to some of the world’s most fascinating bird species. Birds of Nunavut is the first complete survey of every species known to occur in the territory. Co-written by a team of eighteen experts, it documents 295 species of birds (of which 145 are known to breed there), presenting a wealth of information on identification, distribution, ecology, behaviour, and conservation. Lavishly illustrated with over 800 colour photographs and 155 maps, this is a visually stunning reference work on the birds that live in and visit Nunavut.

Book excerpt: "We estimated that 264 000-452 000 Lesser Snow Geese Chen caerulescens caerulescens nested at Egg Riveron Banks Island, Northwest Territories, in 1995-1998. This was about twice as many geese as was reported nesting there in the 1980s, and we estimated that the nesting population grew by 4.2% per year from 1953 to 1998"--Abstract.

This book was released on 2006 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regular surveys of Great Blue Heron (Ardea herodias) colonies in Quebec, conducted between 1977 and 2001, resulted in the discovery of 705 colonies, mostly in the western part of the province. While single breeding pairs were occasionally found (9% of Quebec "heronries"), the colonies were generally composed of fewer than 16 breeding pairs, with sometimes over 50 (18 known colonies), as was the case on several islands in the St. Lawrence River. Close to one-third (1919 of the 6481 active nests) of the Quebec Great Blue Heron population was associated with heronries in the St. Lawrence system. Half of the St. Lawrence heronries that were active during two adjacent survey periods (1975-1983 and 1984-1990, or 1984-1990 and 1991-2001) increased in size between periods, while one-third of the colonies decreased in size. One-sixth of the colonies remained the same size during the study period. Great Blue Herons periodically abandon their colonies and settle elsewhere. Our data show that 50% of known Quebec colonies (n = 377 colonies visited more than once) were abandoned after being discovered as active colonies, and, on average, all nests in colonies that are abandoned disappear 7 years after discovery of the colony. On the basis of thorough inventories conducted on the St. Lawrence, we found that all nest platforms in 14 of the 70 colony sites had disappeared in less than 25 years. Since 1977, when regular surveys began, 50-90% of breeding attempts have been successful, yielding an average of over 2.2 chicks per pair. This productivity rate suggests that the Quebec population of Great Blue Herons may be increasing and may explain the recent expansion in its range. Following our 25 years of investigation on the Great Blue Heron in the province, we estimate the current late-summer Great Blue Heron population of Quebec at some 27 000 individuals (6500 pairs producing 2.2 young per pair per year).--Publisher's description.
