Mangroves, seagrass and coral reefs often occur in association in tropical coasts, so-called tropical seascapes. These seascapes provide critical ecosystem services, and their conservation ensures long-term carbon storage which is of pivotal importance for climate change mitigation. Ecosystem functions and performance are enhanced by biogeochemical linkages between the individual habitats (connectivity) but these can be disrupted by natural and anthropogenic perturbations. The potential cascading effects, and the seascape-scale implications of anthropogenic disruptions are unknown. Therefore, this project will investigate how biogeochemical connectivity across seascapes influences their ability to cope with imposed disturbances when anthropogenic activities are the drivers of change.
