Study on the reproductive output of the non-zooxanthellate colonial coral Astroides calycularis (Scleractinia, Dendrophyllidae) naturally living at CO2 vents in Ischia Island.
The escalating impacts of climate change, particularly ocean acidification, pose unprecedented challenges to marine biodiversity. This study investigates the resilience of Astroides calycularis populations at Magician's Cave in Ischia, Italy, to natural high-CO2 exposure. Through reproductive a...

This study investigates the resilience of Astroides calycularis populations at Magician's Cave in Ischia, Italy, to natural high-CO2 exposure.
