Results of multiple linear regression analyses examining relationships between feeding rate of green sea urchins (<i>Strongylocentrotus droebachiensis</i>) on kelp (<i>Alaria esculenta</i>), and water temperature (T) and urchin body size (S) (test diameter [t.d.], which can take on values from 25 to 60 mm) in each of two temperature ranges in Experiment 1 (see Materials and methods for determination of the temperature breakpoint [12°C] delimiting the temperature ranges).
