Population genetics of the freshwater mussel, Amblema plicata (Say 1817) (Bivalvia: Unionidae): Evidence of high dispersal and post-glacial colonization
Genetic structure in the Lake Erie drainage was similar to that in the Ohio River, and indicates that northern populations were founded from at least two glacial refugia following the Pleistocene, indicating high effective population size and/or highly vagile fish hosts for this species.
Changes Over Time in the Diversity and Distribution of Freshwater Mussels (Unionidae) in the Grand River, Southwestern Ontario
Abstract The Grand River, a major tributary to Lake Erie in southwestern Ontario, historically supported a diverse and abundant freshwater mussel fauna, with 34 species recorded from the system since
Effect of sampling effort on the efficiency of the timed search method for sampling freshwater mussel communities
Researchers who rely on qualitative surveys to determine the presence of rare and endangered mussel species should consider the amount of time they spend at their sites because sampling effort can significantly affect their ability to detect these species.
Population genetics and phylogeography of freshwater mussels in North America, Elliptio dilatata and Actinonaias ligamentina (Bivalvia: Unionidae)
Genetic analysis identified the Ouachita River as an area of significant reproductive isolation for both Elliptio dilatata and Actinonaias ligamentina, and results for AL indicated dispersal followed by low gene flow in northern areas.
Changes in the Biodiversity of Freshwater Mussels in the Canadian Waters of the Lower Great Lakes Drainage Basin Over the Past 140 Years
Abstract Severe declines in the diversity and abundance of freshwater mussels have been documented over the past century in the United States. Although similar trends might be expected in Canada,
Influence of biological factors on concentrations of metals in the tissues of freshwater mussels (Elliptio complanata and Lampsilis radiata radiata) from the St. Lawrence River
Les etudes menees sur les bivalves marins ont montre que les facteurs biologiques peuvent avoir une influence notable sur la bioaccumulation des metaux par ces organismes, mais il n'existe
Characteristics of a Refuge for Native Freshwater Mussels (Bivalvia: Unionidae) in Lake St. Clair
Glycogen concentrations in the tissues of a common and widespread species in the delta suggest that zebra mussels may be adversely affecting physiological condition of unionids in a portion of the Lake St. Clair delta.
Toxicity of leachate from automobile tires to aquatic biota
Leachate remained relatively toxic to rainbow trout over time indicating that the chemicals responsible for toxicity degrade slowly and are non-volatile, and further studies to identify the toxic compounds and to determne the extent of toxicity under field conditions of dilution are necessary.
Toxicity of aqueous and sediment-associated fluoride to freshwater organisms.
Concentrations of fluoride measured in sediments near some industrial point sources exceed some of these toxicity thresholds, and Fluoride is highly mobile in aquatic systems and could potentially reach toxic levels in the water column during dredging to remove fluoride-contaminated sediment.
