Climate change is having many influences on aquatic life, but the two major variables of concern that are known to be increasing over the next century are temperature and CO2. The latter is especially known to impact many marine calcifiers with respect to growth of carbonate minerals. Both temperature and CO2 have long been known to impact acid-base and ion balance, respiratory function, aerobic performance and energetics. Recent studies on larval fish have demonstrated surprisingly dramatic effects of CO2 (at realistic levels for the end of this century) on multiple aspects of central brain function, sensory physiology and behaviour in fish that have clear implications for population level effects. Our understanding of the scope for individual acclimatisation and species adaptation is still very limited, though there are indications of potential within some species. This session aims to bring together research that focuses on establishing the physiological mechanisms that underpin the effects of temperature and/or CO2 on aquatic organisms. In particular we are keen to provide a platform for research that will allow better predictions when extrapolating from effects on individuals to those at the population level.
