Table S5: Laboratory heating experiment of species-specific thermal reaction norms in Calopteryx splendens and C. virgo

Repeated-measures analysis of laboratory heating experiments of C. splendens (N = 40) and C. virgo (N = 31) of both sexes. The dependent variables (=the repeat) was the thorax temperature at the start of the experiment experiment (“Pre-heating”) and at the end of the experiment, after three minutes under a heat lamp (“Post-heating”). The independent variables were Year (2009 and 2009) Species and Sex, which were factors, and ambient temperature at the start of the experiment was a continuous covariate. The significant Thorax temperature * Species interaction is illustrated in Supporting Figure S3. Pre-heating thorax temperature: r2 = 0.494, F6,64 = 12.402; P < 0.001. Post-heating thorax temperature: r2 = 0.373, F6,64 = 7.926; P < 0.001.
