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.

Download or read book Freshwater Mussel Ecology written by David L. Strayer and published by Univ of California Press. This book was released on 2008-06-10 with total page 217 pages. 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.

Download or read book River Algae written by Orlando Necchi JR and published by Springer. This book was released on 2016-06-02 with total page 287 pages. Available in PDF, EPUB and Kindle. 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 Factors Affecting Feeding and Growth of Juvenile Freshwater Mussels Unionidae written by Jennifer Duzan and published by . This book was released on 2008 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Survival and growth rates of caged juvenile mussels were determined at five sites along a thirty kilometer reach of the James River over a six week period in summer. The juveniles were initially 7.5 mm long. Two species were compared: a habitat generalist (Potamilus alatus) and a small stream specialist (Lampsilis reeveiana). Suspended particles in the size range of 1-10 um (a measure of food availablity(increased progressively from upstream to downstream. Water temperature varied among sites and was lowest at the fourth most downstream site and highest at the most downstream site. Mussels were caged with or without access to the substrate, and both upstream and downstream of structure. Growth rate (length/time) was highest at the most downstream site and was strongly correlated with temperature but not with particle concentration. Both species responded similarly, but P. alatus had higher growth than L. reeveiana at all five sites. Juveniles in contact with substrate did not grow faster than those that were not in contact, suggesting that deposited particles were not an important food source. Juveniles caged upstream of structure (a partly buried cinder block) grew more slowly and had lower survival than those caged downstream of structure.

Download or read book The Freshwater Mussels of Ohio written by G. Thomas Watters and published by . This book was released on 2009 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early nineteenth century, a naturalist named Rafinesque stood on the banks of the Ohio River and began to describe the freshwater mussels he found there. Since that time, these animals have earned a place among the most imperiled animals in North America. Dozens of species have become extinct, and it is estimated that two-thirds of the remaining freshwater mussels face a similar fate. Yet, despite their importance, the mussels of Ohio remain a poorly documented and largely mysterious fauna. This book compiles existing research on Ohio's mussels, synthesizing works on genetics, biology, and systematics into one volume. Full-page color images depict shell variation, hinge detail, and beak sculpture. Full-page maps show the distribution of each species based upon the collections of numerous museums, with historical distributions dating from the 1800s. In addition to species accounts, the book has an introductory section that includes information on basic biology, human use, and conservation issues.--adapted from jacket.

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 Freshwater Mussel Propagation for Restoration written by Matthew A. Patterson and published by Cambridge University Press. This book was released on 2018-02-22 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater mussels are declining rapidly worldwide. Propagation has the potential to restore numbers of these remarkable organisms, preventing extinction of rare species and maintaining the many benefits that they bring to aquatic ecosystems. Written by practitioners with firsthand experience of propagation programs, this practical book is a thorough guide to the subject, taking readers through the process from start to finish. The latest propagation and culture techniques are explored as readers follow freshwater mussels through their amazing and complex life cycle. Topics covered include the basics of building a culture facility, collecting and maintaining brood stock, collecting host species, infesting host species with larval mussels, collecting and culturing juvenile mussels, releasing juveniles to the wild, and post-release monitoring. This will be valuable reading for any biologist interested in the conservation of freshwater mussel populations.
