Anthropogenic activities are causing the global climate to change at an unprecedented rate. A plethora of studies have suggested that anomalies in ocean temperature can result in severe drawbacks to the ecology and behaviour of marine species. Further, an increase in concentration of atmospheric CO2 will lead to the disruption of key processes such as calcification, development during larval stages and predator and prey recognition.

Most of these studies, however, do not take into account the capacity of marine organisms to acclimate and adapt. Environmental conditions similar to the ones predicted for the near future occur naturally in fractions of a species’ distribution. Recent studies have highlighted the genetic mechanism by which these populations have adapted locally to these exceptional environments. Further, due to standing genetic variation within populations, a subset of individuals can be more resistant to predicted conditions, aiding in their future persistence. Meanwhile, plastic responses that organisms may express under various conditions have been suggested as a mechanism that could enable acclimation and can be passed on across generations.

This session will address the interplay of both mechanisms of genetic adaptation and phenotypic plasticity and their role in long-term adaptation of marine organisms to changing environments. The goal is to assemble cross-disciplinary studies from a variety of taxa and biological scales, which is imperative to understand the fate of marine ecosystems in the upcoming decades.
