Communicated by R. Cattaneo-Vietti, Genova Abstract In intertidal sediments, burial and decomposition of macroalgal detritus can fuel the sediment of carbon (C) and nitrogen (N), which can be either promptly mineralised or assimilated to enter the food web. This study investigates the transfer of algal-derived C and N to the sediment and to the infauna feeding primarily on benthic diatoms. Thalli of Ulva spp. were 13C- and 15N-labelled in the mesocosm and frozen to create detritus. Thawed macroalgae were, then, buried in the sediment of
