There is increasing interest in the spatial dynamics of marine populations. These dynamics depend on connectivity over space through larval dispersal and the movement of adults. Description of this connectivity forms the basis for implementing Marine Protected Areas, as is currently underway in California and Oregon. We invite presentations on (a) use of circulation models to describe dispersal patterns, (b) observational approaches to estimate connectivity or evaluate modeled patterns, (c) population dynamic consequences of connectivity and (d) projected effects of climate change on connectivity.
