Book excerpt: This study examined the feeding of three co-occurring freshwater mussel species in the Sydenham River at Florence, ON (a turbid river with over 25 unionid species), under static and ecologically relevant flow conditions. Experiments were designed to examine the change in algal composition (clearance rate and feeding electivity) following a feeding experiment in a recirculating flow chamber and an aerated tank to determine whether co-existing mussels feed selectively and/or partition algal resources. I hypothesized that mussel species found within the same reach of a river would feed differently and/or selectively on different algal taxa at different flow to limit competition for resources and therefore coexist. I found that the clearance rate was higher under flowing conditions across all the mussel species on natural seston from a turbid river. This was also found for specific algal taxa, which were identified using a flow cytometer, where higher feeding was observed on four of the nine algal taxa under flowing conditions. All three mussel species selected for larger particles within a 28-35 m size fraction, while rejecting smaller particles (12-19 m). Jacob's Modified Electivity index was calculated for each specific algal taxon, while mussels did not appear to partition resources by size, there was evidence that different mussel species are capable of selectively feeding on different algal species. This study suggests that the maintenance of mussel diversity within the same river may be facilitated by resource partitioning.

Available in PDF, EPUB and Kindle. Book excerpt: Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Book excerpt: The content is focused on benthic communities showing how they play an in important role in the river ecosystems. Provides also information on taxonomy of river-inhabiting algal groups, including phylogeny, distribution, collection, preservation and description of the most representative genera of algae in river benthic algal communities. The book also approaches the ecology of river algae not to mention the ecological factors influencing abundance, distribution and diversity of river benthic algal communities and their use as bio-indicators, providing an up-to-date information on taxonomy, ecology, methodology and uses, and a great source of research to everyone interested in freshwater algae, limnology, water quality assessment and biodiversity in river ecosystems.

Download or read book In the Search of the Lost Pearl written by Igor Popov and published by Springer Nature. This book was released on 2021-03-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph focuses on the European freshwater pearl mussel Margaritifera margaritifera, which is an endangered bivalve species. Most of its populations in the Russian section of the Baltic Sea basin had never been studied, although they were known in the past to the pearl fishers. “Rediscovery” included search for the previously unknown populations, revealing the facts of population extinctions, analysis of negative impacts, elaboration of conservation measures, and revealing of regularities in distribution. Patterns of land use and river management were analyzed. The procedure of “rediscovery” was applied for other animal species of Northwest Russia, which are threatened on a global scale – thick-shelled mussel, Unio crassus; curlew Numenius arquata; black-tailed godwit, Limosa limosa; Northern Lapwing, Vanellus vanellus; European mink, Mustela lutreola; pond bat, Myotis dasycneme; Atlantic sturgeon, Acipenser sturio; and broad-clawed crayfish, Astacus astacus. The methods and principles of conservation studies were discussed. The obtained data were analyzed with respect to current global change of biosphere. The book will appeal to specialists dealing with conservation studies and activities such as red lists, river protection, and conservation of endangered species. Moreover, a part of the book represents an interest for biogerontology as it presents discredit of the popular concept on “negligible senescence.” The data on distribution of some animals in Russia will be interesting in terms of zoology and biogeography, as they are not yet sufficiently represented in the international editions. The book can be used as supplemental reading for courses in biological invasions, ecology and conservation, and biodiversity. The work also contains chapters on global processes (deforestation, desertification, river degradation) and can therefore also be used for general courses in environmental sciences.

Download or read book Ecology and Evolution of the Freshwater Mussels Unionoida written by G. Bauer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: All those who think that bivalves are boring are in the best company. Karl von Frisch is reported to have turned the pages more quickly in texts where bivalves were treated because, according to him, they literally lack any behaviour. The fact that they can filtrate huge amounts of water, burrow into the sedi ment, actively swim, drill holes into rocks and boats or detect shadows with the aid of pretty blue eyes located on the rim of their mantle obviously left v. Frisch unimpressed. Why, then, a book on the large freshwater mussels (Naiads or Unionoida), which on first sight are much less spectacular than the marine ones? The main reason is that they are keepers of secrets which they reveal only on close and careful inspection. This is not only true for the pearls some species produce and which over centuries have contributed to the treasures of bishops and kings, but particularly for their ecology: their life cycles are linked with those of fishes, some can occur in incredible densities and some can live for more than 100 years. Thus, the presence or absence of naiads in a lake or stream has manifold implications.

Download or read book Zebra Mussels Biology Impacts and Control written by Thomas F. Nalepa and published by CRC Press. This book was released on 1992-11-24 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.
