Early development of Calanus glacialis and C. finmarchicus
Abstract Egg and nauplii development of coexisting populations of Calanus glacialis and C. finmarchicus from Disko Bay, western Greenland, were measured in the laboratory with, and without addition of food. Egg hatching rate was measured at five temperatures from 0°C to 10°C and the fit to a Belěhrá...
