Conclusion: Energy use isn't size-independent when environments change and undergoes temporal change. Mediated by species interactions, temperature and biodiversity jointly shape community size structure. This has implications for predicting ecological responses to global warming.

How do these responses change over time? The slope stayed near -0.75 for half of the experiment, then deviated to become shallower. Comparing real communities vs. "no interaction" controls showed that species interactions - not just individual physiology - drive these changing patterns over time.

In species-rich communities, warming favored small protists much more than large ones, steepening the size-abundance slope. At low richness? Temperature had minimal effect. This suggests that complex species interactions amplify thermal effects on community size structure.

Metabolic theory predicts a -0.75 slope: smaller organisms are more abundant. We confirmed this overall pattern across 53 protist communities spanning 1 to 6 species and 15 to 25°C. But here's the caveat: temperature and richness INTERACT to modify this relationship, not just shift the intercept.

Biodiversity modulates the cross‐community scaling relationship in changing environments Organismal abundance typically declines with increasing body size, with metabolic theory predicting a universal size–abundance slope of –0.75. Using protist microcosms across gradients of species ric...

Does body size predict abundance the same way in all environments, as predicted by the Metabolic theory of Ecology? Our new study challenges this assumption. Read it here: 📄 doi.org/10.1111/ele....
