Download or read book Quagga and Zebra Mussels written by Thomas F. Nalepa and published by CRC Press. This book was released on 2013-10-25 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatment facilities and power plants, and they can have other negative impacts by altering aquatic environments. In the 20 years since the first edition of this book was published, zebra mussels have continued to spread, and quagga mussels have become the greater threat in the Great Lakes, in deep regions of large lakes, and in the southwestern Unites States. Quagga mussels have also expanded greatly in eastern and western Europe since the first book edition was published. Quagga and Zebra Mussels: Biology, Impacts, and Control, Second Edition provides a broad view of the zebra/quagga mussel issue, offering a historic perspective and up-to-date information on mussel research. Comprising 48 chapters, this second edition includes reviews of mussel morphology, physiology, and behavior. It details mussel distribution and spread in Europe and across North America, and examines policy and regulatory responses, management strategies, and mitigation efforts. In addition, this book provides extensive coverage of the impact of invasive mussel species on freshwater ecosystems, including effects on water clarity, phytoplankton, water quality, food web changes, and consequences to other aquatic fauna. It also reviews and offers new insights on how zebra and quagga mussels respond and adapt to varying environmental conditions. This new edition includes seven video clips that complement chapter text and, through visual documentation, provide a greater understanding of mussel behavior and distribution.

Download or read book Notes from an Island written by Tove Jansson and published by Sort of Books. This book was released on 2021-10-07 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the bitter winds of autumn 1963, Tove Jansson, helped by Brunström, a maverick fisherman, raced to build a cabin on a treeless skerry in the Gulf of Finland. The island was Klovharun, and for thirty summers Tove and her beloved partner, the graphic artist, Tuulikki Pietilä, retreated there to live, paint and write, energised by the solitude and shifting seascapes. Notes from an Island, published in English for the first time, is both a chronicle of this period and a homage to the mature love that Tove and 'Tooti' shared for their island and for each other. Tove's spare prose, and Tuulikki's subtle washes and aquatints combine to form a work of meditative beauty. '... Tooti wandered aimlessly around the island and stood stock still for long periods. I thought I knew what she was doing. She was working again. Copperplate etchings and wash drawings. Mostly the lagoon, the lagoon as a consummate mirror for clouds and birds, the lagoon in a storm, in fog. And the granite, first and foremost, the granite, the cliff, the rocks. It's all peace and quiet now.'

Download or read book Lipids in Freshwater Ecosystems written by Michael T. Arts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental purpose of this book is to synthesise the divergent literature on aquatic lipids into a co-ordinated, digestible form. A large part of the book addresses lipid composition and production in freshwater organisms, with chapters on phytoplankton, zooplankton and benthic invertebrates. A common theme throughout the book is the function of lipids in aquatic food webs, with a chapter devoted exclusively to lipids as indicators of health in fish populations. A complementary chapter highlights the role of lipids and essential fatty acids in mariculture. Methodologies to determine the lipid content of aquatic samples and suggestions as to the utility of fatty acids as trophic markers are included, as is one chapter on the role of lipids in the bioaccumulation and bioconcentration of toxicants and another on the relationships between lipids and surface films and foams. The final chapter highlights the similarities and differences between lipids of marine and freshwater origin. Students and researchers in ecology, phycology, aquatic toxicology, physiological ecology and limnology will find this an invaluable guide and reference.

Download or read book Gulls of Europe Asia and North America written by Klaus Malling Olsen and published by A&C Black. This book was released on 2010-06-30 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eagerly awaited guide offers the most comprehensive treatment ever published on the gulls of Europe, Asia and North America. A total of 43 species is treated, and every species is described in considerable detail, with a full description of each plumage and racial variation. Gulls are intelligent, versatile, opportunistic, and ecological generalists. As such, they exploit a variety of habitats, both coastal and inland, take a wide range of food, and are often extremely abundant. They are also great wanderers, with several American species regularly appearing in Western Europe and vice versa. As well as identification criteria, this book includes an up-to-date assessment of the range and status of every species, together with information on patterns of vagrancy. This important guide is published at a critical time in the development of dull taxonomy. The large, white-headed forms occurring in the region comprise a superspecies complex, with the precise relationships between the various components still under considerable debate. A thorough illustrative and textual treatment of the group is much needed, and this book provided the most complete overview of the complex. The text is complemented not only by superb colour paintings by Hans Larrson, but also by a large selection of colour photographs, sourced from some of the finest bird photographers in the world. This is the essential reference to a fascinating and endlessly challenging group of birds.

Download or read book British Tits written by Christopher Perrins and published by Collins. This book was released on 2009-07-14 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to dealing with the general biology and behaviour of the birds, Dr Perrins gives full attention to such things as their social lives, their intelligence and adaptiveness, and their puzzling ability to adjust their population sizes to the future availability of food. This edition is exclusive to newnaturalists.com Because of their ubiquity and apparent boldness, the tits are among the most easily observed, and the most popular, of all British birds. The Blue Tit, particularly, is an attractive and confident bird and will arrive at a well-stocked bird table, or at a bag of peanuts outside a window, within a few minutes of its being set out. Curiously, little has been written about tits for the general naturalist. In this book, Christopher Perrins, who succeeded the late David Lack at the Edward Grey Institute of Ornithology in Oxford, sets out to remedy this omission. Dr Perrins has spent many years studying these small birds in great detail and has himself made many important discoveries about their lives and behaviour. The book deals with seven species of tit. These include the six members of the true tits - Coal, Great, Blue, Crested, Marsh and Willow Tits - as well as the more distantly related Long-tailed Tit. In addition to dealing with the general biology and behaviour of the birds, Dr Perrins gives full attention to such things as their social lives, their intelligence and adaptiveness, and their puzzling ability to adjust their population sizes to the future availability of food. Dr Perrin's study demonstrates that there is much unsuspected complexity - some of it still not clearly understood - in the lives of even the most popular of groups of birds; as such it will be of interest to every birdwatcher, amateur and professional alike.
