Abstract

Temperature and salinity effects on respiration of Mnemiopsis leidyi, the new invader of the Baltic Sea 1 2 Abstract 3 To evaluate the influence of temperature along salinity gradients on metabolic performance, we measured 4 respiration rate of fully acclimatized adults of invasive ctenophore Mnemiopsis leidyi under similar field 5 conditions representative for the Baltic Sea. Three levels of temperature (3, 8 and 17°C) and three levels of 6 salinity (12, 17 and 22‰) were considered. Oxygen consumption was temperature and not salinity dependent, 7 albeit combinations of temperature and salinity showed a significant effect on carbon specific respiration rate. 8 Q 10 value of 3.67 indicates a strong impact of temperature on metabolic regulation. The role of combined effect 9 of temperature and salinity on over-wintering population in higher latitudes was discussed.
