This book was released on 2012-12-06 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds are an integral part of most freshwater ecosystems (lakes, rivers, wetlands) but their role in the trophic dynamics of these water bodies has often been overlooked. As a conspicuous part of the biota of water bodies, aquatic birds are indicators of their trophic state both in terms of species composition (quality) as well as occupancy and breeding (quantity). Birds may also influence the trophic state of a water body by importing nutrients (.e.g. resident or migrating birds feeding on adjacent watersheds or the sea). Because of anthropogenic activities, predation or their mobility, birds may not utilize otherwise suitable aquatic habitat. These factors complicate the relationship between aquatic bird production and the trophic status of habitats. As a consequence, the role of aquatic birds in freshwater ecosystems has usually been ignored. This volume contains a wide range of papers selected from those presented at the symposium and reviewed.

Download or read book The Birds of Africa Volume II written by and published by Bloomsbury Publishing. This book was released on 2020-05-29 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, hundreds of informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This second volume in the series deals comprehensively with the guineafowl, francolins, buttonquails, rails, cranes, finfoot, bustards, jacanas, painted-snipe, Crab Plover, oystercatchers, stilits and avocets, thick-knees, coursers and pratincoles, plovers and lapwings, sandpipers and allies, skuas, gulls, terns, skimmers, auks, sandgrouse and pigeons. The editors and artists have worked closely with other authors - all acknowledged experts in their field - to produce a superb reference in which comprehensive texts on every species are complemented by accurate and detailed paintings and drawings of the birds themselves.
Download or read book Storks Ibises and Spoonbills of the World written by James Hancock and published by A&C Black. This book was released on 2010-09-30 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the world's largest and most spectacular birds are to be found among this group of wading birds. Tragically, they also include many of the world's most endangered species, as changes in land use erode their wetland habitats. Some like the White Stork have lived alongside humans for hundreds of years and are well known from numerous studies. Others, like the Storm's stork and ibises of West Africa, South-East Asia and South America live so secluded a life in the remote corners of the globe that they will probably be extinct before even the most basic details of their biology are known. In this monograph, three authors and two artists have combined their skills to capture what is known of this group of wading birds. The text opens with general chapters on taxonomy and feeding, breeding and behavior, followed by detailed coverage of each species.
