Book Description
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.

Book Description
Long-term population monitoring is an important tool in our investigations of the role waterbirds play in their environment. This book is international in scope and presents information on species as diverse as the Common Loon, Harlequin Duck, and Semi-Palmated Sandpiper, and habitat in locations ranging from Iceland to Japan. Papers presented in this volume further our understanding of the important role that limnology plays in determining habitat suitability for waterbirds.

Book Description
Twelve birds. One country. A wild Ireland waiting to be discovered. In Ireland Through Birds, Conor O’Brien takes the reader on an ornithological adventure around Ireland in search of twelve of our rarest and most elusive birds. Along the journey the author explores every kind of landscape and habitat our island has to offer across all four seasons, from the remote isles of Donegal to the rugged mountains of Kerry and urban parks of Dublin. Through it all, O’Brien is enchanted by calling corncrakes, mesmerised by hunting harriers, and chased by angry skuas. It’s a journey through a staggering array of landscapes that’ll bring the reader face to face with the rich history and stunning wildlife to be savoured right on our doorstep. It explores the stories of the remarkable birds that live here: the genius of the jay, the sublime mimicry of the cuckoo, the nocturnal prowess of the barn owl, while paying a moving,poetic tribute to our natural heritage – and a warning about the threats that face it. Ireland Through Birds is a unique blend of natural history and travelogue, making it a great read for anyone with an interest in Ireland’s natural world.

Book Description
A charismatic and arresting bird, the Painted Stork inhabits the plains and wetlands of India and Southeast Asia. This near-threatened species provides a good model through which to explore a variety of ecology and conservation issues. As a colonial nester, it is also useful for considering questions related to evolution and the development of avian coloniality. The Painted Stork sometimes nests opportunistically in the middle of large cities – the Delhi Zoo colony, for instance, has been active since 1960. This offers a splendid opportunity to study the species at close range, as attested by this book's lively photographic component. The Painted Stork is an important indicator of its wetland habitats, which themselves are highly threatened. Since environmental toxins, particularly organochlorine pesticides, travel rapidly along aquatic food chains, the study of piscivorous birds like the Painted Stork assumes special significance. Equally vulnerable today are the nesting colonies, located in marshes, village reservoirs and the wider countryside, including in urban settings. Perhaps because their natural nesting areas are becoming scarce due to habitat loss, colonial waterbirds look for suitable sites in parks and gardens. Hence, the behaviour of this species reflects changes occurring in its environment. Birds also help us monitor the effects of global climate change, and one of the most significant dimensions of the Painted Stork is its dependence upon the monsoon. How exactly do these seasonal rains govern the food cycles in wetlands? And what happens when the monsoon fails? Covering all aspects of Painted Stork ecology, behaviour, conservation and its relationship with humans, this accessible monograph contains a wealth of new insights.

Book Description
The rapid growth of the discipline of aquatic ecology has been driven both by scientific interest in the complexities of aquatic ecosystems and by their enormous environmental importance and sensitivity. This book focuses on the remarkably diverse roles played by underwater plants, and is divided into three parts: 10 thematic chapters, followed by 18 case studies, and rounded off by three integrative chapters. The topics range from macrophytes as fish food to macrophytes as mollusc and microbe habitat, making this of interest to aquatic ecologists as well as limnologists, ecosystem ecologists, microbial ecologists, fish biologists, and environmental managers.

Book Description
The best-selling and authoritative reference book on waterfowl has been fully revised and updated by one of the world’s most respected waterfowl biologists. Honorable Mention for the PROSE Award for Excellence, Multivolume/Science of the Association of American Publishers Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with stunning images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: • identification • distribution • migration behavior • habitat • population status • breeding biology • rearing of young • recruitment and survival • food habits and feeding ecology • molts and plumages • conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. This edition of Ducks, Geese, and Swans consists of two volumes, printed in full color, and packaged in a slipcase, along with a CD containing references and additional maps.
