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.针对两性个体的亮斑丽翅蜻（C. splendens，N=40）与大蓝丽翅蜻（C. virgo，N=31）的实验室升温实验，本研究开展了重复测量分析。本实验的因变量（即本次重复测量的响应指标）为实验开始时的胸温（"预热前"），以及热灯下照射三分钟后实验结束时的胸温（"预热后"）。自变量为作为分类因子的年份（2009与2009）、物种与性别，实验开始时的环境温度为连续协变量。胸温与物种间的显著交互作用详见补充图S3。预热前胸温：决定系数r²=0.494，F检验值F₆,₆₄=12.402，P<0.001；预热后胸温：决定系数r²=0.373，F检验值F₆,₆₄=7.926，P<0.001。
