The impact of population abundance on the deposit-
feeding rate of Mediomastus ambisetu (Capitellidae:
Polychaeta) was studied in still-water laboratory experiments.
Mean individual pellet production rate (mg worm¯¹ d¯¹) decreased
monotonically with increasing worm abundance in the
range of 6.5 X 10³ to 1.3 X 10⁵ worms m¯². Worms fed...
