| Abstract: | "Ocean acidification (OA) can induce changes in marine organisms and species interactions. We examined OA effects on intertidal macroalgal growth, palatability, and consumption by a specialist crab (Pugettia producta) and a generalist snail (Tegula funebralis) herbivore. Moderate increases in pCO(2) increased algal growth in most species, but effects of pCO(2) on C:N and phenolic content varied by species. Elevated pCO(2) had no effect on algal acceptability to herbivores, but did affect their preference ranks. Under elevated pCO(2), electivity for a preferred kelp (Egregia menziesii) and preference rankings among algal species strengthened for both P. producta and T. funebralis, attributable to resilience of E. menziesii in elevated pCO(2) and to changes in palatability among less-preferred species. Preferred algae may therefore grow more under moderate pCO(2) increases in the future, but their appeal to herbivores may be strengthened by associated shifts in nutritional quality and defensive compounds in other species" |
