CACHE-ITN to co-chair a session at the SEB Annual Meeting

CACHE-ITN are co-chairing a session at the SEB Annual Meeting in Gothenburg on Thursday 6 July
A4: Challenges in the Anthropocene: acid-base/ion regulation and calcification in aquatic invertebrates

One of the biggest scientific challenges of the 21st Century is to understand and predict the impact of climate change on marine and freshwater (FW) life (e.g. ocean and FW acidification, increased temperature and hypoxia). In particular, we need to understand the effects on fundamental physiological mechanisms and the consequential adaptation of aquatic biota to predict future biodiversity. The bodies of water of our planet are becoming warmer and more acidic, they are intrinsically linked with human health and wellbeing and are therefore of immense socio-economic importance. For example, invertebrates are at the bottom of the food chain and thereby of significant ecological and in the case of crustaceans and molluscs, often also of economic importance. The significance of understanding the mechanistic basis for acid-base and ion transport and regulation lies in the identification of key physiological processes that can determine species´ sensitivity to environmental disturbance. Identification of physiological processes that limit the capacity of a species to acclimate to changing environmental conditions provides the basis for hypotheses-driven approaches to study evolutionary adaptation in times of rapid climate change.
This one-day session will highlight key physiological processes in acid-base regulation, ion transport, calcification/regulation and the energy allocation involved, with special emphasis on invertebrates. In addition, linked to this session, “speed” presentations (Pecha Kucha) allowing early career scientists to pitch their work, will summarise key findings in recent research in this area, including implications and strategies for the aquaculture industry.
