Size is a fundamental organismal trait and an important driver of ecosystem functions.
Although large individuals may dominate some functions and provide important habitat
structuring effects, intra-specific body size effects are rarely investigated in the context of
BEF relationships. We used an in situ density manipulation experiment to explore the
contribution of large, deep-burrowing bivalves to oxygen and nutrient fluxes across the
sediment-water interface. By manipulating bivalve size structure through the removal of …
