Description:

Metapopulation and source –sink dynamics are increasingly considered within spatially expli- cit management of wildlife populations, yet the application of these concepts has generally been limited tocomparisons of the performance (e.g., demographic rates or dispersal) inside vs. outside protected areas,and at spatial scales that do not encompass an entire metapopulation. In the present study, a spatiallyexplicit, size-structured matrix model was applied to simulate the dynamics of an Eastern oyster ( Cras- sostrea virginica ) metapopulation in the second largest estuary in the United States —the Albemarle-Pamlico Estuarine System in North Carolina. The model integrated larval dispersal simulations with empirical mea- sures of oyster demographic rates to simulate the dynamics of the entire oyster metapopulation consistingof 646 reefs and ﬁve reef types: (1) restored subtidal reefs closed to harvest (i.e., sanctuaries or protected areas; n=14), (2) restored subtidal reefs open to harvest ( n=53), (3) natural subtidal reefs open to harvest (n=301), (4) natural intertidal reefs open to harvest ( n=129), and (5) oyster reefs on manmade, hard
