Ocean acidification affects growth but not nutritional quality of the seaweed Fucus vesiculosus (Phaeophyceae, Fucales)

Abstract: Understanding the ecological implications of global climate change requires investigations of not only the direct effects of environmental change on species performance but also indirect effects that arise from altered species interactions. We performed CO 2 perturbation experiments to investigate the effects of ocean acidification on the trophic interaction between the brown seaweed Fucus vesiculosus and the herbivorous isopod Idotea baltica. We predicted faster growth of F. vesiculosus at elevated CO 2 -conc… Show more

“…We did not find a significant interaction between acidification and nutrients loading on tissue C:N, similar to Falkenberg et al (2013). Our results contradict those from Gutow et al (2014), where high pCO 2 resulted in a decreased C:N ratio for F. vesiculosus.…”

“…These studies used concentrations of pCO 2 expected in the next 50-100 years, whereas our study focused on the more extreme pCO 2 projection for the year 2100. However, the response of macroalgae is still highly species-specific, and neutral or negative impacts of ocean acidification on growth rate have been observed in non-calcifying macroalgae (Cornwall et al, 2012;Gutow et al, 2014;Israel and Hophy, 2002;Mercado and Gordillo, 2011). Divergent responses of macroalgae to acidification are likely due to the differences in CCM effectiveness, potentially giving certain species more independence from the environment, or CCMs are optimized for higher pH conditions and their activity is sensitive to pH (Axelsson et al, 2000;Moulin et al, 2011).…”
