The Potential Influence Of Abiotic Conditions On Mussel Species Abundance In San Francisco Bay, Alexandra G. Farrell, M. Christina Vasquez Dr.
Honors Thesis
Climate change has negatively altered seawater conditions, which may have severe implications for marine ecosystems. Mussels are susceptible to environmental changes since they are primary consumers and filter-feeding bivalves. Two species of particular interest to the West Coast of the U.S. are Mytilus galloprovincialis and M. trossulus. M. trossulus is native to the California Coast and was historically prevalent from Southern California to Washington. However, with increased shipping and rising seawater temperature, M. galloprovincialis, an invasive species from the Mediterranean, pushed the species range of M. trossulus poleward. M. trossulus is more tolerant of cold seawater with variable salinity while …

Effect Of Hyposaline Stress On Metabolic Rate Of The Invasive Mussel Mytilus Galloprovincialis, Hayley C. Hart
Honors Thesis
Climate change is predicted to decrease ocean salinity as the polar ice caps melt and the occurrence of precipitation events increases. Decreased ocean salinity (hyposalinity) may negatively impact marine invertebrates, especially marine mussels, as they are osmoconformers and their internal osmolarity depends on the solute concentration of their environment. Hyposalinity stress may influence cell function and alter mussel physiology. To compensate for the change in the environment, mussels may expend more energy to restore internal osmolarity, which can be assessed by quantifying metabolic rate. Thus, the purpose of our research was to examine the physiological response of Mytilus galloprovincialis, …
