Eelgrass re-establishment in shallow estuaries is affected by drifting macroalgae – Evaluated by agent-based modeling.

Highlights: [•] An agent based model was developed to simulate unattached macroalgae in a fjord. [•] Bottom drifting macroalgae generate sediment resuspension and reduce light availability. [•] The reduced light availability at the seabed and the ballistic effect generated by drifting macroalgae negatively affect eelgrass populations. [•] The model simulates the monitored macroalgae distribution. [•] The model simulates the location of hot spots where eelgrass recovery is affected by macroalgae stress. [Copyright &y& Elsevier]
