Ocean acidification impacts growth and shell mineralization in juvenile abalone (Haliotis tuberculata)
Ocean acidification (OA) is a major global driver that leads to substantial changes in seawater carbonate chemistry, with potentially serious consequences for calcifying organisms. Marine shelled molluscs are ecologically and economically important species, providing essential ecosystem services and...
