Adult acclimation to combined temperature and pH stressors significantly enhances reproductive outcomes compared to short-term exposures
This study examined the effects of long-term culture under altered conditions on the Antarctic sea urchin, Sterechinus neumayeri.Sterechinus neumayeri was cultured under the combined environmental stressors of lowered pH (-03 and -05 pH units) and increased temperature (+2 degrees C) for 2years.
