The dispersal of propagules is a critical process for most terrestrial and marine systems. For example, it has been shown that larval dispersal enables to connect fish populations in networks of marine reserves. However, most current marine reserves models include an over-simplified representation of dispersal. The major limitation to using more sophisticated approaches has traditionally been the uncertainty surrounding larval dispersal patterns. We report recent improvements in methods and tools for modelling and measuring larval dispersal and show how they will allow integrating modelling of marine reserves into the wider field of landscape modelling.
