Comparative Proteomics: Assessing The Variation In Molecular Physiology Within The Adductor Muscle Between Mytilus Galloprovincialis And Mytilus Trossulus In Response To Acute Heat Stress, Joshua Scott Mier

Master's Theses

Increases in seawater temperatures have imposed physiological constraints which are partially thought to contribute to recently observed shifts in biogeographic distribution among closely related intertidal ectotherms. For instance, Mytilus galloprovincialis an introduced warm-adapted species from the Mediterranean, has displaced the native cold-adapted congener, M. trossulus, over large latitudinal expanses off the California coast. Several comparative physiological studies have revealed interspecific differences in thermal tolerance, including variation in aerobic metabolism and gape behavior, which suggest the invasive congener is better adapted to acclimate to increasing seawater conditions as predicted due to climate change. However, current analyses seek to discover the …
