Assessing toxicity of contaminants in riverine suspended sediments to freshwater mussels.
The Clinch River in Virginia and Tennessee, USA, is well known for its diverse native freshwater mussel assemblages; however, notable declines in mussel populations in recent decades have prompted much concern and subsequent research. The authors examined the toxicity of recently deposited sediments on juveniles of the freshwater mussel Epioblasma brevidens by collecting time-integrated sedimen...
متن کاملPlasticity and trade-offs in physiological traits of intertidal mussels subjected to freshwater-induced environmental variation
Environmental gradients play an important role in shaping geographic variability in coastal marine populations. Thus, the ability of organisms to cope with these changes will depend on their potential to acclimatize, or adapt, to these new environmental conditions. We investigated the spatial variability in biological responses shown by Perumytilus purpuratus mussels collected from 2 intertidal...
متن کاملContaminant Sensitivity of Freshwater Mussels ACUTE TOXICITY OF COPPER, AMMONIA, AND CHLORINE TO GLOCHIDIA AND JUVENILES OF FRESHWATER MUSSELS (UNIONIDAE)
The objective of the present study was to determine acute toxicity of copper, ammonia, or chlorine to larval (glochidia) and juvenile mussels using the recently published American Society for Testing and Materials (ASTM) Standard guide for conducting laboratory toxicity tests with freshwater mussels. Toxicity tests were conducted with glochidia (24to 48-h exposures) and juveniles (96-h exposure...
متن کاملCommunity and foodweb ecology of freshwater mussels
Freshwater mussel (Superfamily Unionoidea) communities are important components of food webs, and they link and influence multiple trophic levels. Mussels filter food from both the water column and sediment with ciliated gills. Differences in cilia structure and arrangement might allow mussel species to partition food resources. Mussels are omnivores that feed across trophic levels on bacteria,...
متن کاملHigh suspended solids as a factor in reproductive failure of a freshwater mussel
Elevated suspended solids are a widespread stressor of aquatic ecosystems, but their effects on growth and reproduction in freshwater mussels are largely unknown. We fertilized experimental ponds to create a gradient in total suspended solids (TSS) and examined the effects of TSS on growth, nutritional status, reproduction, and clearance rate in Ligumia subrostrata. The number of females that b...
