Introduction Davy is Ireland’s leading provider of wealth management and investment banking services. This year we celebrate our centenary, a timely opportunity to reflect on the firm’s evolution since its establishment as a small stockbroker in Dublin’s city centre in 1926. Our early decades played out against a backdrop of profound economic and social change, with the disruption of the old wealth order post-Independence benefiting our business hugely.

1 INTRODUCTION As climate change causes more frequent and severe aquatic heat waves (e.g. Tassone et al., 2023; Woolway et al., 2021), scientists are increasingly focused on understanding the thermal biology of aquatic animals. Tolerance to acute temperature changes, as experienced during heat waves, is typically assessed through experiments that involve gradual increases in temperature (e.g. degrees per minute or per hour).

Abstract Evolution of warming tolerance may help species resist the impacts of climate change but can also lead to negative fitness outcomes. Identifying correlated responses to warming tolerance evolution could identify such negative consequences and help uncover the underlying mechanisms.
