Endogenous levels of heat-shock proteins in the 70-kDa class (hsp70 isoforms) and profiles of induction temperature for newly synthesized hsp70 were measured in freshly field-collected specimens as functions of loca-tion height in the intertidal and season, and in mussels after 7 weeks of laboratory thermal acclimation.

Humans have eaten California Mussels for thousands of years and they were introduced to the diet of European and American pioneers by the Native Americans living on the Oregon Coast. Biol. Marine Biology, Vol. At the remaining two sites (Boiler Bay, OR, and Chibadehl Rocks, WA), small acorn barnacles prevailed. The shell exterior is often worn and eroded due to wave action, while the shell interior is blue-grey with an iridescent sheen.
