An investigation of the calcification response of the scleractinian coral Astrangia poculata to elevated pCO2 and the effects of nutrients, zooxanthellae, and gende

Corals collected in Woods Hole, Massachusetts, exhibited a complex set of responses when exposed to ocean acidification conditions, different nutrient levels, and two different temperatures. For example, female corals were more sensitive than males to elevated CO2 levels. Considering gender and spawning may be important when considering how populations of marine calcifiers will change in response to ocean acidification. (Laboratory study)
