15 days on the ground, 35 dives, and a very productive field season to understand metapopulation dynamics in clownfish (specifically Amphiprion clarkii). This is a multi-year project using genetic parentage methods to identify parents and offspring on the reef. See here for a few photos! Thanks to the the Marine Lab at Visayas State University for hosting us.
Malin will be talking about his larval dispersal research at the International Coral Reef Symposium, July 11, 10:15am, Session 14A. This will cover both the use of genetics to estimate larval dispersal kernels, and the interaction between those kernels and habitat patchiness.
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.
