Parameter values for the seagrass model scenarios where growth was modelled R – Mt and Mt = a1 Warming + a2 Local + a3 Warming Local + K.

*with both stresses.Interaction values were chosen so that overall mortality rates were never greater than those in the model of [9]. The interaction strength (a3) is weaker for the dominance antagonism than the mitigative antagonism, to reflect the different processes that cause these types of interactions.
