Figure 3.

Mean (±SE) larval growth rate (mg/time) of C. vicina larvae reared with conspecifics, or reared with P. regina larvae at various temperatures. Indicator variable linear regression with interaction was conducted on the product of larval mass (mg) and time (in h) over time (not shown) for each species treatment and temperature combination. Slope (growth rate) differs at 15 and 25 °C (r² = 0.89, F_1,53 = 6.46, p = 0.01; r² = 0.93, F_1,19 = 13.5, p = 0.002, respectively). Overall growth rate differs at 25 and 30 °C (r² = 0.93, F_1,19 = 14.1, p = 0.001; r² = 0.94, F_1,23 = 5.44, p = 0.03, respectively).
