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 Freshwater Bivalve Ecotoxicology written by Jerry L. Farris and published by CRC Press. This book was released on 2006-11-16 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Responding to the growing need for an aggressive yet conservative approach to evaluating mussel populations, Freshwater Bivalve Ecotoxicology provides a collective review of the techniques and approaches for assessing contaminant impact on freshwater ecosystems. The editors incorporate coverage of research topics and management issues from a cross-section of scientists in the field. They explore current advances in general monitoring of population responses to stressors, fundamental concepts of ecotoxicology specific to burrowing bivalves, and useful insights that offer direction and priority for resolving specific problems challenging protection and conservation efforts. This book lays the groundwork with discussions of topics such as impact assessment, toxicokinetics, biomarkers, and pollution tolerance. The authors then explore fundamental concepts surrounding responses measured in freshwater bivalves as a consequence of chemical exposures or accumulated contaminants in target organs or tissues. They highlight the difficulties encountered with the laboratory culture of these organisms for toxicity testing or other controlled experiments, and examine the use of surrogate test organisms to relate sensitivities of response and reduce pressure on already impacted fauna. The book also reviews innovative field research using in situ bivalve toxicity testing, discusses effects-oriented tissue contaminant assessment, and concludes with threefour specific laboratory or combined field/laboratory ecotoxicology studies. A summary of methods from more than 75 laboratory toxicity studies conducted with freshwater mussels, the book provides an overview of a standardized method for conducting water-only acute and chronic laboratory toxicity tests with glochidia juvenile freshwater mussels. It focuses on studies that report measured contaminant treatments, had robust experimental designs, including replication of control and contaminant treatments, and were published in the peer-reviewed literature. The resulting array of viewpoints provides a framework that can be used to establish priorities in the rehabilitation and management of freshwater ecosystems.
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 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 Factors Affecting Metamorphosis Success of Larval Freshwater Mussels Unionidae written by Andrea K. Crownhart and published by . This book was released on 2009 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Larval parasitism of fish is a critical stage in the lifecycle of freshwater mussels (Unionoida). Most fish species are innately immune to most mussel species, and each mussel is able to utilize only particular host species. The evolutionary origin and mechanisms of host specificity are not well understood. Metamorphosis success (%M = percent of attached glochidia that successfully metamorphose) was analyzed for 25 mussel species and 41 mussel-host species pairs. Mean %M of 14 mussel species with large carnivorous hosts was 79% (range=57-92%). Among individual fish, %M varied from near zero to 100%, with mean CV=0.16. Mussels with small insectivorous hosts (n=21) had lower %M with mean=40% (range=2-71%) and greater variations among individual fish (CV=0.49). The %M of six mussel species-host pairs that attach to fins as well as gills was also low with mean %M=24% (range 19-42%). However, in simultaneous infections %M was higher on fins than gills (p=
