dc.description.abstract The deep reef refugia hypothesis proposes that deep reefs can act as local recruitment sources for shallow reefs following disturbance. To test this hypothesis, nine polymorphic DNA microsatellite loci were developed and used to assess vertical connectivity in 583 coral colonies of the Caribbean depth-generalist coral Montastraea cavernosa. Samples were collected from three depth zones (<= 10, 15-20 and >= 25 m) at sites in Florida (within the Upper Keys, Lower Keys and Dry Tortugas), Bermuda, and the U.S. Virgin Islands. Migration rates were estimated to determine the probability of coral larval migration from shallow to deep and from deep to shallow. Finally, algal symbiont (Symbiodinium spp.) diversity and distribution were assessed in a subset of corals to test whether symbiont depth zonation might indicate limited vertical connectivity. Overall, analyses revealed significant genetic differentiation by depth in Florida, but not in Bermuda or the U.S. Virgin Islands, despite high levels of horizontal connectivity between these geographic locations at shallow depths. Within Florida, greater vertical connectivity was observed in the Dry Tortugas compared to the Lower or Upper Keys. However, at all sites, and regardless of the extent of vertical connectivity, migration occurred asymmetrically, with greater likelihood of migration from shallow to intermediate/deep habitats. Finally, most colonies hosted a single Symbiodinium type (C3), ruling out symbiont depth zonation of the dominant symbiont type as a structuring factor. Together, these findings suggest that the potential for shallow reefs to recover from deep-water refugia in M. cavernosa is location-specific, varying among and within geographic locations likely as a consequence of local hydrology.
dc.description.sponsorship The authors thank M. Durante, N. Polato, D. Ruiz and C. Vera for help with the 454 sequencing data. M. Moon, N. Kurata, H. Wirshing, P. Jones, R. Cunning, R. Silverstein, R. Winter and A. Palacio helped in the laboratory. Field assistance was provided by R. Gomez, D. Lirman, T. Thyberg, S. Manley, S. Grey, J. Calnan and the crew at BIOS (in particular C. Eddy, T. Noyes and A. Chequer). Sampling in the Lower Keys and Dry Tortugas was completed thanks to the help of D. Swanson and the International SeaKeepers Society, in particular, D. Klevan, B. Stockman, J. Jacoby and the crew of Miss Phebe II. Special thanks go to P. Beerli for statistical assistance with the program MIGRATE. Finally, the authors would like to thank PSU's Genomics Core Facility for the 454 sequencing, and UM's Molecular Core Facility and Cornell's Life Sciences Core Laboratories Center for the genotyping and sequencing. Samples from the Florida Keys were collected under research permits FKNMS-2002-011, FKNMS-2010-030A1, FKNMS-2011-087, SAL-11-1182-SRP and DRTO-2012-SCI-0009. Samples from the USVI were collected under permits F/SER28:BT and STT-021-10. Samples from Bermuda were collected and exported under permits SP09060 and CITES 09BM0021. This research was supported with funds from MOTE (Protect Our Reefs Grants 2009-2012) and NOAA's Center for Sponsored Coastal Ocean Research under award NA11NOS4780045 to the University of Miami. X. Serrano was supported by a McKnight Doctoral Fellowship, a BIOS Grant-in-Aid (2009), an Alumni Award and small boat funding from RSMAS, and funding from NOAA's LMRCSC.
