Population dynamics:mortality/predation
Background
•Calanus mortality varies spatially and temporally on GB;
losses due to mortality > advective
losses
•Invertebrate predators include Centropages, Metridia, Temora, Sagitta, and Pleurobrachia
•High
consumption of all copepod life stages by the hydroid Clytia gracilis, particularly on the crest; predator populations peak there in April-May
•Cannibalistic
feeding by C.
finmarchicus may lead
to density- dependent mortality.
