The biology of harpacticoid copepods in the meiofauna of shallow subtidal sands
Synopis An account is given of the benthic harpacticoid copepods of a medium grade subtidal sand at a depth of 8–5 m (below chart datum) off the Ayrshire coast at Hunterston. It is the first account of seasonal changes in subtidal harpacticoids in the Firth of Clyde. Most of the population is restri...
