An investigation of the calcification response of the scleractinian coral Astrangia poculata to elevated p CO 2 and the effects of nutrients, zooxanthellae and gender

open access: yes, 2012
. The effects of nutrients and pCO2 on zooxanthellate and azooxanthellate colonies of the temperate scleractinian coral Astrangia poculata (Ellis and Solander, 1786) were investigated at two different temperatures (16 °C and 24 °C).
