Calcifying algae maintain settlement cues to larval abalone following algal exposure to extreme ocean acidification
Ocean acidification (OA) increasingly threatens marine systems, and is especially harmful to calcifying organisms. One important question is whether OA will alter species interactions. Crustose coralline algae (CCA) provide space and chemical cues for larval settlement. CCA have shown strongly negat...
