Dataset for Devenish et al 'Predicting effects of warming on insect pollinators using the metabolic theory of ecology'

We tested whether the main predictions of the Metabolic Theory of Ecology (MTE) hold for four species of globally distributed pollinating insects: <i>Eristalis tenax</i>, <i>Lucilia sericata</i>, <i>Apis mellifera</i>, and <i>Bombus terrestris</i>. We used a closed respirometry system to measure insect CO₂ production rates across a continuous range of temperatures (15- 35°C). We tested four major hypotheses derived from the MTE: 1) metabolism will scale with body mass following a ¾ power-law relationship, 2) metabolism positively scales exponentially with temperature according to Arrhenius’ Law, 3) the slopes (i.e., activation energy) of the temperature-metabolism relationship falls within the range of -0.60 and -0.70 eV, and 4) hypotheses 1-3 hold, both within and among species.

本研究验证了生态学代谢理论（Metabolic Theory of Ecology, MTE）的核心预测是否适用于4种全球分布的传粉昆虫：长尾管蚜蝇（Eristalis tenax）、丝光绿蝇（Lucilia sericata）、西方蜜蜂（Apis mellifera）与地熊蜂（Bombus terrestris）。我们采用密闭呼吸代谢系统（closed respirometry system），在15~35℃的连续温度区间内测定了昆虫的CO₂产生速率。本研究基于MTE提出了四项核心假说：1）代谢速率将以3/4次幂律关系随体重缩放；2）根据阿伦尼乌斯定律（Arrhenius’ Law），代谢速率会随温度呈指数级正向增长；3）温度-代谢速率关系的斜率（即活化能）处于-0.60至-0.70电子伏特（eV）的区间内；4）假说1至3在物种内部及物种间均成立。
