Description
Summary:Ontogenetic changes in respiration rate of Calanus euxinus from the Black and Marmara Seas and C. helgolandicus from the Ionian Sea under different salinity and temperature conditions were studied. Respiration rates in nauplii of C. euxinus from the Black and Marmara Seas were similar whilst at the same temperature weight-specific respiration rate in late copepodite stages and females from the Marmara Sea (22 – 38.5 ‰) was 1.8-fold higher than that in the individuals from the Black Sea (18 ‰). Weight-specific respiration rate in closely-related C. helgolandicus from the Ionian Sea (39 ‰) was 2-fold higher than that in C. euxinus from the Black Sea. Temperature coefficient of respiration rate Q10 for all stages from nauplii to females of the Marmara Sea C. euxinus on average amounted to 1.94 and did not differ from Q10 of the copepods from the Black Sea. The difference in respiration rates of late copepodite stages and females of С. еuxinus from the Black and Marmara Seas seems to be due to various salinity regimes of their habitat.
