Data from: On the occurrence of false positives in tests of migration under an isolation with migration model

Jody Hey, Yujin Chung & Arun Sethuraman
The population genetic study of divergence is often carried out using a Bayesian genealogy sampler, like those implemented in ima2 and related programs, and these analyses frequently include a likelihood ratio test of the null hypothesis of no migration between populations. Cruickshank and Hahn (2014, Molecular Ecology, 23, 3133–3157) recently reported a high rate of false-positive test results with ima2 for data simulated with small numbers of loci under models with no migration and recent...

Data from: Testing the depth-differentiation hypothesis in a deepwater octocoral

Andrea M. Quattrini, Iliana B. Baums, Timothy M. Shank, Cheryl L. Morrison & Erik E. Cordes
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 geographical distances, Callogorgia delta was targeted. This species...
