Predicted levels of future ocean acidification and temperature rise could alter community structure and biodiversity in marine benthic communities

submitted by: R_Hale
 A mesocosm experiment was conducted to quantify the effects of pH and temperature on an intact marine invertebrate community. Standardised communities from the low intertidal zone were exposed to one of eight nominal treatments (four pH × two temperature levels). After 60 days exposure communities showed significant changes in structure and diversity. At higher pH levels elevated temperature treatments contained higher species abundances and diversity than the lower temperature treatments.
