Abstract(s)
Ocean acidification is known to trigger deleterious effects on several marine photosynthetic invertebrates [1]. Photosymbiosis, whereby photosynthetic microorganisms or organelles live inside an animal (host) is widespread in the marine biota, underlying a wide range of ecologically and biogeochemically significant
processes that remain largely unclear [1]. One of the most remarkable symbiosis is between sacoglossan molluscs and algal chloroplasts [2]. These organisms are able to “steal” functional chloroplasts (termed kleptoplasts) from their algal prey and keep them functional inside digestive diverticula [2]. The aim of this study was to investigate the impact of environmental hypercapnia on cellular structures of kleptoplastic animals. Elysia viridis (Sacoglossa) were exposed to different pH conditions (pH 8, 7.5, 6.8 and 6.1) for 24 h.
