From: Warming neutralizes host-specific competitive advantages between a native and invasive herbivore
Temperature effect on the performance of two Pieris butterfly species under intraspecific (black dots) and interspecific (red dots) competition on two host plant species (Rorippa indica and Brassica oleracea). Pieris performance traits (mean ± SE) include larval period (a,b), pupal fresh weight (c,d), adult dry weight (e,f), and forewing length (g,h). Pc and Pr indicate the native Pieris canidia and invasive P. rapae, respectively. The temperatures at 18.5 °C, 21.5 °C, and 24.5 °C represent control, 3 °C, and 6 °C warming, respectively. The statistical results are listed in Supplement 5 (ANOVA results), 6 (post hoc comparisons across temperature), and 7 (comparisons between intra- and interspecific competition). The P-values in the figure indicate that Pieris thermal performance differs between intraspecific and interspecific competition at a specific temperature.
