We investigated the effects of temperature and CO2 variation\udon the growth and elemental composition of cultures of the diatom\udPseudo-nitzschia subcurvata and the prymnesiophyte Phaeocystis antarctica, two ecologically dominant phytoplankton species\udisolated from the Ross Sea, Antarctica. To obtain thermal functional\udresponse curves, cultures were grown across a range of temperatures from\ud0 to 14 °C. In addition, a co-culturing experiment examined the\udrelative abundance of both species at 0 and 6 °C. CO2\udfunctional response curves were conducted from 100 to 1730 ppm at 2 and 8 °C to test for interactive effects between the two variables. The\udgrowth of both phytoplankton was significantly affected by temperature\udincrease, but with different trends. Growth rates of P. subcurvata increased with\udtemperature from 0 °C to maximum levels at 8 °C, while\udthe growth rates of P. antarctica only increased from 0 to 2 °C.\udThe maximum thermal limits of P. subcurvata and P. antarctica where growth stopped completely were\ud14 and 10 °C, respectively. Although P. subcurvata outgrew P. antarctica at\udboth temperatures in the co-incubation experiment, this happened much faster\udat 6 than at 0 °C. For P. subcurvata, there was a significant\udinteractive effect in which the warmer temperature decreased the CO2\udhalf-saturation constant for growth, but this was not the case for P. antarctica. The\udgrowth rates of both species increased with CO2 increases up to 425 ppm, and in contrast to significant effects of temperature, the effects of\udCO2 increase on their elemental composition were minimal. Our results\udsuggest that future warming may be more favorable to the diatom than to the\udprymnesiophyte, while CO2 increases may not be a major factor in future\udcompetitive interactions between Pseudo-nitzschia subcurvata and Phaeocystis antarctica in the Ross Sea
