Table S4: Analysis of species-specific thermal reaction norms of Calopteryx splendens and C. virgo

General Linear Model (GLM), involving three factors (Year, Species, Sex) one continuous covariate (Ambient temperature) and all two-way interactions. Data from Klingavälsåns Naturreservat from the summers of 2009 and 2010 (N = 200). The significant Species * Ambient temperature interaction in the table is illustrated in Fig. 6C (see Results). This interaction show that the two species (C. splendens and C. virgo) differ significantly in the slopes of their thermal reaction norms. Full model: r2 = 0.216; F10,189 = 6.481; P < 0.001.
