Effects of temperature and food availability on feeding and egg production of Calanus hyperboreus from Disko Bay, western Greenland
The effects of temperature and food availability on feeding and egg production of the Arctic copepod Calanus hyperboreus were investigated in Disko Bay, western Greenland, from winter to spring 2009. The abundance of females in the near bottom layer and the egg production of C. hyperboreus prior to...
