Spatial pattern formation (IMAGE) Utrecht University Caption Spatial pattern formation of mussels and diatoms on a tidal flat. This pattern formation allows tipping points caused by sea level rise to be evaded, so that tidal flats do not drown. The spatial patterns on the tidal plate, including the waves, are based on mathematical model simulations. Credit Johan van de Koppel / Ulco Glimmerveen (birds).
