| 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. This time-scale covered two full reproductive cycles in this species and analyses included studies on both adult metabolism and larval development. Adults took at least 6-8months to acclimate to the altered conditions, but beyond this, there was no detectable effect of temperature or pH. Animals were spawned after 6 and 17months exposure to altered conditions, with markedly different outcomes. At 6months, the percentage hatching and larval survival rates were... |
