A 0.25-m2 box core from the Aleutian Trench (50°58.0'N, 171°37.5'W) was used to generate hypotheses concerning the regulation of benthic community structure in oceanic trenches. High food supply and the concentrating effects of trench topography are suggested by the unexpectedly high standing crop (1272 individuals of macrofaunal taxa m2) and by the feeding modes of the captured polychaetes....
