    Testing the depth-differentiation hypothesis in a deepwater octocoral
    ( 2015-03) Quattrini, Andrea M. ; Baums, Iliana B. ; Shank, Timothy M. ; Morrison, Cheryl L. ; Cordes, Erik E.
    The depth-differentiation hypothesis proposes that the bathyal region is a source of genetic diversity and an area where there is a high rate of species formation. Genetic differentiation should thus occur over relatively small vertical distances, particularly along the upper continental slope (200-1000 m) where oceanography varies greatly over small differences in depth. To test whether genetic differentiation within deepwater octocorals is greater over vertical rather than geographic distances, Callogorgia delta was targeted. This species commonly occurs throughout the northern Gulf of Mexico at depths ranging from 400-900 m. We found significant genetic differentiation (FST=0.042) across seven sites spanning 400 km of distance and 400 m of depth. A pattern of isolation by depth emerged, but geographic distance between sites may further limit gene flow. Water mass boundaries may serve to isolate populations across depth; however, adaptive divergence with depth is also a possible scenario. Microsatellite markers also revealed significant genetic differentiation (FST=0.434) between C. delta and a closely-related species, C. americana, demonstrating the utility of microsatellites in species delimitation of octocorals. Results provided support for the depth-differentiation hypothesis, strengthening the notion that factors co-varying with depth serve as isolation mechanisms in deep-sea populations.

    Multilocus microsatellite genotypes of Acropora palmata from the Caribbean and North-West Atlantic from 2015-2016 (Coral Hybridization project)
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2021-02-24) Baums, Iliana B.
    Genotypes for the coral, Acropora palmata collected throughout the Caribbean from five microsatellite loci . A. palmata is a diploid species, however, somatic mutations in the form of third and fourth alleles per locus are occasionally detected. Data are in columns of region, database_id, genet_id, mutant_id, locus, allele, and size_bp. These data were deposited in DRYAD: http://dx.doi.org/10.5061/dryad.f6600 and published in the paper Devlin-Durante et al, Mol Ecol. (2016).

    Palau's warmest reefs harbor thermally tolerant corals that thrive across different habitats
    (Nature Research, 2022-12-21) Rivera, Hanny E. ; Cohen, Anne L. ; Thompson, Janelle R. ; Baums, Iliana B. ; Fox, Michael D. ; Meyer-Kaiser, Kirstin S.
    Ocean warming is killing corals, but heat-tolerant populations exist; if protected, they could replenish affected reefs naturally or through restoration. Palau's Rock Islands experience consistently higher temperatures and extreme heatwaves, yet their diverse coral communities bleach less than those on Palau's cooler outer reefs. Here, we combined genetic analyses, bleaching histories and growth rates of Porites cf. lobata colonies to identify thermally tolerant genotypes, map their distribution, and investigate potential growth trade-offs. We identified four genetic lineages of P. cf. lobata. On Palau's outer reefs, a thermally sensitive lineage dominates. The Rock Islands harbor two lineages with enhanced thermal tolerance; one of which shows no consistent growth trade-off and also occurs on several outer reefs. This suggests that the Rock Islands provide naturally tolerant larvae to neighboring areas. Finding and protecting such sources of thermally-tolerant corals is key to reef survival under 21century climate change.
