SEB Gothenburg 2017 Session Report: Challenges in the anthropocene - Acid-base/ion regulation and calcification in aquatic invertebrates

Organised by: Dirk Weihrauch (University of Manitoba, Canada), Marian Hu (Kiel University, Germany), Kati Michalek (SAMS, UK), Nadège Zaghdoudi-Allan (University of Algarve, Portugal)


Over the past few years the wide but greatly understudied field of invertebrate physiology, particularly the topic acid-base regulation in the context of global change, gained considerable momentum. The SEB annual meeting in Gothenburg was an ideal venue to bring researchers from around the globe together to present their current work in our session “Challenges in the Athropocene: Acid-base regulation and calcification in aquatic invertebrates”.  Under this overarching theme quite an array of topics were covered including calcification processes and acid-base regulatory mechanisms in corals and echinoderms, comparative studies on cephalopod ammonia regulation, pCO2 changes in developing aeshnids, but also how crustaceans maintain acid-base homeostasis in their respective marine and freshwater habitats challenged with predicted future environmental acidifications, and how they even  survive most extreme conditions found in close proximity to hydothermal vents.  Another focus was set on the effects of global change on calcification processes in bivalves by the “CACHE” cluster.  This session was one of the rare events where invertebrate physiologist came together as a group and had a chance to interact and to initiate new collaborations. Clearly, studying invertebrate acid-base physiology becomes of growing importance.  With ca. 95% of all animals being invertebrates which are building the basis of our fragile and threatened ecosystem, research on this topic needs to be supported urgently. SEB is provides an ideal platform for this.
