【 摘 要 】

ABSTRACT: Sessile epifauna that excrete ammonium as a waste product are often closely associated with surfaces of macroalgae that are able to absorb and use ammonium for growth. This close association means that nitrogen provisioning from epifauna to host macroalgae is probable, but barriers to uptake, formed by epifaunal colonies, and the physiological status of colonised macroalgal tissue may limit the amount of ammonium absorbed by colonised macroalgae. Evidence for the movement of nitrogen from sessile epifauna into and around the giant kelp
