Effects on Scope for Growth due to elevated carbon dioxide in the copepod Calanus finmarchicus
Cohorts of the keystone copepod species Calanus finmarchicus exposed to simulatedocean acidification environments were followed during the course of two consecutivegenerations. The time of development into the different molting stages were monitored.While the more moderate CO2 concentration(1080 ppm...
