dichotoma, suggesting that future losses of biogenic habitat may be an important indirect effect of OA on caprellids. We also found a strong, positive association between caprellid population size and the availability of OA-vulnerable O. We found that OA resulted in elevated caprellid heart rates, suggestive of increased metabolic demand. Indirect effects were explored by quantifying caprellid habitat dependence on the hydroid Obelia dichotoma, which has been shown to be less abundant under experimental acidification. Direct physiological effects were assessed by measuring caprellid heart rate in response to acidification in the laboratory. Here, we assess the potential direct and indirect effects of OA on a ubiquitous group of crustaceans: caprellid amphipods ( Caprella laeviuscula and Caprella mutica).

Although OA impacts will be the sum of direct effects mediated by alterations of physiological rates and indirect effects mediated by shifts in species interactions and biogenic habitat provision, direct and indirect effects are rarely considered together for any given species. Ocean acidification (OA) is one of the most significant threats to marine life, and is predicted to drive important changes in marine communities. Caprellid amphipods ( Caprella spp.) are vulnerable to both physiological and habitat-mediated effects of ocean acidification.
