We studied the response in development times of Calanus finmarchicus and Calanus helgolandicus to changes in temperature and food conditions. The ingestion response to temperature was determined in the laboratory, where the copepods C. finmarchicus and C. helgolandicus were fed the diatom Thalassiosira weissflogii (cultivated at 18°C-20°; 12 : 12 light :dark cycle; exponential growth). C. finmarchicus was obtained for experiments from the Gullmar fjord. C. finmarchicus was incubated at in situ temperature (5°C) until the experiments were performed. First-generation cultures were grown in the laboratory at 15°C from the eggs from the Sta. L4 females. During growth both C. finmarchicus and C. helgolandicus cultures were fed a mixture of the cryptophyte Rhodomonas salina, the diatom Thalassiosira weissflogii, and the dinoflagellate Prorocentrum minimum. Five 600-mL glass bottles containing 1400 cells mL**-1 or 5 mg chlorophyll a (Chl a) L**-1 of T. weissflogii (200 mg C) and 1-2 C. finmarchicus or C. ... : Supplement to: Møller, Eva Friis; Maar, Marie; Jónasdóttir, Sigrún Huld; Nielsen, Torkel Gissel; Tönnesson, Kajsa (2012): The effect of changes in temperature and food on the development of Calanus finmarchicus and Calanus helgolandicus populations.
