New insights into larval dispersal

Larvae disperse across patchy seascapes, and yet we typically assume that those seascapes are uniform. In a new paper in Ecological Applications, Malin and co-authors tease apart the consequences of this seemingly simple fact: Pinsky et al. 2012 Open and closed seascapes: Where does habitat patchiness create populations with high fractions of self-recruitment? As the title suggests, isolated habitat patches can have high self-recruitment, even without unusually short dispersal distances.

Guerry et al. 2012 Modeling benefits from nature: using ecosystem services to inform coastal and marine spatial planning is now out in the International Journal of Biodiversity Science, Ecosystem Services, and Management. The paper describes a suite of tools for calculating marine ecosystem services from a seascape and sets the stage for the rest of the Marine Natural Capital Project.
