Trade-offs between coral traits: implications for natural selection and assisted evolution on coral reefs

With Liam Lachs, Newcastle University

Under climate change, marine heatwaves are becoming ever more damaging, and for coral reefs, mass coral bleaching and mortality events ever more common. Accordingly, individual coral heat-tolerance will likely become a major driver of natural selection in the future.

As all organisms must balance energy allocation between vital physiological processes, there can be trade-offs between heat-tolerance and other adaptive traits (i.e. growth and reproduction). Such trade-offs can have individual-, population- and even ecosystem-level consequences.

However, we outline a considerable gap in the current scientific knowledge about such trade-offs relating to heat-tolerance in corals. Finding answers in this space can help to (1) understand the natural adaptation of corals to climate change, and (2) inform restoration actions that aim to boost coral reef resilience.
