Rising global temperatures are changing how energy and materials move through ecosystems, with potential consequences for the role of animals in these processes. We tested a central prediction of the metabolic scaling framework—the temperature independence of animal community production—using a series of geothermally heated streams and a comprehensive empirical analysis. We show that the apparent temperature sensitivity of animal production was consistent with theory for individuals (Ep_ind = 0.64 vs. 0.65 eV), but strongly amplified relative to theoretical expectations for communities, both among (Ep_among = 0.67 vs. 0 eV) and within (Ep_within = 1.52 vs. 0 eV) streams. After accounting for spatial and temporal variation in resources, we show that the apparent positive effect of temperature was driven by resource supply, providing strong empirical support for the temperature independence of invertebrate production and the necessary inclusion of resources in metabolic scaling efforts.

资源供应决定着河流生态系统中动物生产的明显温度依赖性

全球气温上升正在改变能源和物质在生态系统中的传播方式，这可能会对动物在这些过程中的作用产生影响。我们使用一系列地热加热流和综合的经验分析，测试了代谢缩放框架的中心预测-动物群落生产的温度独立性。我们表明，动物生产的表观温度敏感性与个体理论相符（E p _ind  = 0.64 vs. 0.65 eV），但相对于理论上对社区的期望值，两者都大大增强了（E p _between  = 0.67 vs. 0 eV） ）和内（E p_内 = 1.52 vs. 0 eV）流。在考虑了资源的时空变化之后，我们表明温度的明显积极影响是由资源供应驱动的，为无脊椎动物生产的温度独立性和代谢扩展工作中必要的资源提供了有力的经验支持。
