Key Points

The aim is to evaluate the functional connectivity of marine protected areas (MPAs) with a focus on the European flat oyster.
Developed an interdisciplinary evaluation method for MPAs
Combined genetic evidence of oyster presence with biophysical modelling
Tested connectivity using Borkum Reef Ground and Sylt Outer Reef
Oyster larvae from the Borkum Reef Ground only reach the Sylt Outer Reef under very favorable wind conditions
Indicates limited functional connectivity between the two MPAs

Abstract

• European legislation requires that marine protected areas (MPAs) be established in a network in such a way that their effects reinforce each other • We have developed an interdisciplinary method for evaluating such functional connectivity and tested it using the example of the European flat oyster Ostrea edulis in the North Sea • Combining genetic evidence of presence with biophysical modelling revealed that oyster larvae from the MPA Borkum Reef Ground only reach the MPA Sylt Outer Reef under extremely favourable wind conditions
