Decreased growth and increased shell disease in early benthic phase Homarus americanus in response to elevated CO2
Marine calcifiers, especially those in larval and juvenile stages, are thought to be most vulnerable to ocean acidification (OA) due to the effects of carbon dioxide (CO2) on growth and calcification. However, recent evidence in lobsters is contradictory. We monitored molting activity, length, and w...
