Figure 4.

Feeding rate of M. trossulus based on collection location, temperature acclimation and test temperature. Asterisks indicate significant differences between mussels acclimated to constant and variable temperatures. (a) Mussels from Tofino, BC, (b) Mussels from Reed Point, BC. There was no significant effect of test temperature on mussels from either location, but mussels acclimated to variable temperature conditions had significantly lower feeding rates than mussels acclimated to constant 12°C. All values shown are means ± s.e.
