The Impact Of Tidal Elevation And Climate Change On The Growth And Performance Of Balanus Glandula, Sam Martin

Pitzer Senior Theses

Tidal elevation affects the survival, growth, and performance of intertidal organisms because it regulates their exposure to heat, waves, food availability, and a variety of other abiotic factors. While previous research has explored the relationship between temperature and the performance of the barnacle Balanus glandula, there are unanswered questions about how tidal elevation affects B. glandula performance and growth. I compared the growth of B. glandula at three tidal elevations in Friday Harbor, Washington, and estimated the metabolic cost of emersion at each tidal elevation using a cost equation gained from thermal performance curves and average daily maximum temperatures. …
