Population energy use scales positively with body size in natural aquatic microcosms

Aim We test the ‘energetic equivalence rule’ (EER) – the idea that the amount of energy used by a population per unit area per unit time is independent of body mass – in meio‐invertebrate communities from a series of natural, multitrophic aquatic ‘rock pool’ microcosms. Our study represents the first rigorous test of the EER at local scales of observation in a community of naturally coexisting species. Location Discovery Bay, Jamaica. Method We …
