Calcifying Response and Recovery Potential of the Brown Alga Padina pavonica under Ocean Acidification
Anthropogenic carbon dioxide (CO2) emissions are causing ocean acidification (OA), which affects calcifying organisms. Recent studies have shown that Padina pavonica investigated along a natural pCO2 gradient seems to acclimate to OA by reducing calcified structures and changing mineralogy from arag...
