Match/mismatch between the Mytilus edulis larval supply and seston quality: effect on recruitment.

Examining the physiological plasticity of particle capture by the blue mussel, Mytilus edulis (L.): Confounding factors and potential artifacts with studies utilizing natural seston

The use of larval fatty acids as an index of growth in Mytilus edulis L. larvae

Continuous cultures of Chaetoceros muelleri, Skeletonema costatum and Rhinomonas reticulata of controlled biochemical compositions were fed to Mytilus edulis larvae over a 2-week period and the larval growth was assessed. The eggs as well as the larvae which subsequently developed were analyzed for their relative fatty acid profile and content; 27 fatty acids were identified by means of GCrMS. ...

Effects of exposure and previous exposure to copper on growth of veliger larvae and survivorship of Mytilus edulis juveniles

Exposure of Mytilus edulis L. (Molluscs: Bivalvia) to 8 ppb (ppb = 1-lg I ' ) added copper during the vellger larval or post-larval (spat) stages has no significant effects on survivorship or shell growth However, previous exposure to 8 ppb added copper d u r ~ n g the embryo stage significantly Increases veliger growth rate and decreases spat survivorship in a population from the Menal S t r a...

Across-shelf distribution of blue mussel larvae in the northern Gulf of Maine: consequences for population connectivity and a species range boundary

Studies of population connectivity have largely focused on along-shelf, as opposed to across-shelf, processes. We hypothesized that a discontinuity in across-shelf mixing caused by the divergence of the Eastern Maine Coastal Current (EMCC) from shore acts as an ecological barrier to the supply of mussel larvae to the coast. Existing data on the relative abundance of two congeneric blue mussels,...

Patterns of larval dispersal and their effect on the maintenance of a blue mussel hybrid zone in southwestern England.

The blue mussels Mytilus edulis and M. galloprovincialis hybridize in southwestern England. Within this hybrid zone environmentally based directional selection favors individuals with alleles specific to M. galloprovincialis. What forces are countering this directional selection and allowing for the maintenance of a stable hybrid population are unknown. We used both the genetics of recently set...
