Download or read book The Common Eider written by Chris Waltho and published by Bloomsbury Publishing. This book was released on 2015-01-15 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: A monograph of the Common Eider, a large and familiar duck with a long and fascinating cultural history. A common sight around the more northerly shores of the British Isles, the Common Eider is the largest duck in the northern hemisphere. The eider is particularly well adapted to cold-water environments; the insulating properties of eider down are iconic. The species is taxonomically interesting, with a range of well-marked subspecies reflecting the patterns of ice coverage during ancient glaciations, and these ducks have also provided the focus for a number of important behavioural studies, especially on feeding ecology and energy budgets. Eiders have a long association with humans, and have deep cultural significance in many societies. However, modern lifestyles are exposing these ducks to a wide range of new pressures. This monograph provides a comprehensive portrait of the Common Eider; authors Chris Waltho and John Coulson bring together an extensive and diverse international literature, with sections on taxonomy, habitats, breeding biology, population dynamics, diet and foraging, dispersal and migration, and conservation.
Download or read book Bivalvia Through Reptilia written by T Pandian and published by Elsevier. This book was released on 2012-12-02 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Energetics, Volume 2: Bivalvia through Reptilia is part of a two-volume treatise focusing on the integrated picture of the energy transformation process at the organismic level. Since it is almost impossible to restrict meaningful discussions to only one level of organization, some reference is made to population energetics as well as to the suborganismic level. The bioenergetics of both vertebrate and invertebrate groups are discussed. Specifically, the bioenergetics of bivalves, gastropods, bryozoans, pogonophorans, echinoderms, lower chordates, fishes, amphibians, and reptiles are covered. Understanding the efficient and fast transformation of biological energy has become an important issue in world affairs; studies on energetics and growth of thermoconformers can therefore be expected to expand greatly in the future. This book aims to provide many keys to a broader understanding of biology as well as open untrodden avenues to biologists with the quest for newer energy sources and efficient methods of energy utilization.
Download or read book The Mollusca written by and published by Academic Press. This book was released on 2012-12-02 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mollusca, Volume 5: Physiology, Part 2 focuses on the biochemistry and physiology of mollusks. The selection first elaborates on the feeding biology of gastropods and feeding and digestion in Bivalvia and cephalopods. Discussions focus on feeding, digestion, feeding and digestive rhythms, feeding behavior, ontogeny of gastropod feeding biology, and feeding mechanisms. The text then examines the circulatory systems of gastropods and bivalves and circulation in cephalopods, including blood vessels and extracellular space, chemical control of the circulation, fluid mechanics of the circulation, and nature and anatomy of the circulatory system. The text takes a look at ionic regulation and water balance, excretion, and molluscan immunobiology. Topics include internal defenses of gastropods, bivalves, cephalopods, and Polyplacophorans, Monoplacophora, Cephalopoda, and Scaphopoda. The selection is a vital reference for researchers interested in the biochemistry and physiology of mollusks.
Download or read book Between Pacific Tides written by Edward Flanders Ricketts and published by Stanford University Press. This book was released on 1985 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the classic works of marine biology, a favorite for generations, has now been completely revised and expanded. Between Pacific Tides is a book for all who find the shore a place of excitement, wonder, and beauty, and an unsurpassed introductory text for both students and professionals. This book describes the habits and habitats of the animals that live in one of the most prolific life zones of the world--the rocky shores and tide pools of the Pacific Coast of the United States. The intricate and fascinating life processes of these creatures are described with affectionate care. The animals are grouped according to their most characteristic habitat, whether rocky shore, sandy beach, mud flat, or wharf piling, and the authors discuss their life history, physiology, and community relations, and the influence of wave shock and shifting tide level. Though the basic purpose and structure--and much of the text--of the book remain the same, content has been increased by about 20 percent; a multitude of changes and additios has been made in the text; the Annotated Systematic Index and General Bibliography have been updated and greatly expanded (now almost 2,300 entries); more than 200 new photographs and drawings have been incorporated; and an entirely new chapter has been added--a topical presentation of the several factors influencing distribution of organisms along the shore. This edition also includes John Steinbeck's Foreword to the 1948 edition.

Download or read book Pollutant Diseases Remediation and Recycling written by Eric Lichtfouse and published by Springer Science & Business Media. This book was released on 2014-01-25 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollution has no borders. This popular 70’s saying from early ecologists is surprisingly still true nowadays despite overwhelming scientific evidence and public awareness of the occurrence of artificial toxic substances in water, food, air, living organisms and the environment. This book presents advanced reviews on pollutant occurrence, transfer, toxicity and remediation. The chapter on school air quality by Dambruoso et al. highlights the overlooked health issue of airborne pollutants in buildings. Children are particularly threatened because they spend 90% of their time indoors, even in summer. The chapter on industrial wastewater pollutants by Dsikowitzky and Schwarzbauer reviews pollutants from textile, petrochemical, paper, tire, chemical and pharmaceutical plants. The authors describe advanced analytical methods and ecotoxicity tests. Industrial pollutants include dioxins and furans that are also reviewed in the chapter by Mudhoo et al. The chapter on fly ash by Gianoncelli et al. presents many techniques to treat fly ash and, in turn, decrease pollutant concentrations. The authors also explain that fly ash can be recycled in agriculture, buildings and geopolymers. The chapter on antifouling paints used for ship protection, by Sousa et al., highlights the occurrence of toxic organotins in human organs such as heart, liver and breast milk. The chapter on surfactants by Rebello et al. focuses on safety concerns for humans and the ecosystems. Remediation techniques and green surfactants are presented. The chapters on toxic metals by Nava-Ruíz and Méndez-Armenta, Abarikwu and Ristić et al. describe sources, monitoring and diseases induced by lead, mercury, cadmium and thallium. The chapter on carcinogenic nitrosamines by Li et al. presents techniques and materials such as zeolites to remediate liquids and smoke containing nitrosamines.
Download or read book Biological Effects by Organotins written by Toshihiro Horiguchi and published by Springer. This book was released on 2016-12-07 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the induction mechanism of imposex caused by organotin compounds in gastropods, as well as fundamental information on the physiology and biochemistry of reproduction in mollusks. Are the sex hormones of gastropod mollusks vertebrate-type steroids, or neuropeptides? What about lipid disturbance and membrane toxicity due to organotin compounds? The book also discusses the latest findings on the role of nuclear receptors, such as retinoid X receptor (RXR), retinoic acid receptor (RAR) and peroxisome proliferator-activated receptor (PPAR), in the development of imposex in gastropods. Further, it describes the current state of contamination by organotins in the marine environment and gastropod imposex, with a special focus on Europe and Asia, introduces readers to analytical techniques for organotin compounds, and assesses the contamination and adverse effects of alternatives to organotin-based antifouling paints. Imposex, a superimposition of male genital tracts, such as penis and vas deferens, on female gastropod mollusks, is known as a typical phenomenon or consequence of endocrine disruption in wildlife. Imposex is typically induced by very low concentrations of organotin compounds, such as tributyltin (TBT) and triphenyltin (TPhT) from antifouling paints on ships and fishing nets. Reproductive failure may be brought about in severely affected stages of imposex, resulting in population decline and/or mass extinction. Thus, gastropod imposex has been recognized as a critical environmental pollution issue. Although gastropod imposex is also highly interesting for the biological sciences because of its acquired pseudohermaphroditism and/or sex change by certain chemicals, such as TBT and TPhT, the mechanism that induces the development of imposex remains unclear, possibly due to our limited understanding of the endocrinology of gastropod mollusks. This book offers a useful guide for professionals and students interested in the fields of aquatic biology, invertebrate physiology, ecotoxicology and environmental science.

Download or read book Estuarine Processes written by Martin Wiley and published by Academic Press. This book was released on 2014-05-10 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuarine Processes, Volume II: Circulation, Sediments, and Transfer of Material in the Estuary provides information pertinent to estuarine processes and focuses on dynamic interactions at several levels of organization. This book describes the effects of physical alterations on estuarial hydraulics, dissolved and particulate material support, and on aquatic biota. Organized into six parts encompassing 27 chapters, this volume begins with an overview of the historic changes in salinity balance in the estuarial zone of the Sacramento-San Joaquin Delta. This text then reviews the effect of enlargement of artificial waterway of the Chesapeake and Delaware Canal, which has resulted in substantial alterations of the physical hydrography, biotic populations and chemical environment of the canal and its approaches. Other chapters consider the elements in a mathematical model for estuarial sediment transport. This book discusses as well sediment transport rates in coastal waters. The final chapter deals with accurate estimates of fish abundance for models of many estuarine processes. This book is a valuable resource for ecologists, environmentalists, and scientists.
