The effect of changes in temperature and food on the development of Calanus finmarchicus and Calanus helgolandicus populations
We studied the response in development times of Calanus finmarchicus and Calanus helgolandicus to changes in temperature and food conditions. Grazing experiments were performed at different temperatures for both species, and the results were implemented in a stage‐resolved zooplankton population mod...
