Glaucus Study II: locality data, GenBank and museum voucher numbers, with molecular synapomorphies from a global sample set (Neuston Phylogeny project)

<p>These samples are part of a study that suggests the premise that continents like Europe and the Americas cause barriers to gene flow for the nudibranchs found in the uppermost layer (neuston) of the ocean. The nudibranch&nbsp;<em>Glaucus atlanticus</em>, found in all oceans, was studied to assess the genetic differentiation of mulitiple specimens from a global sampling effort.</p> <p>This dataset contains molecular diagnostic traits (synapomorphies) for <em>Glaucus atlanticus</em> and <em>Glaucus&nbsp;marginatus</em> morphospecies in &nbsp;mitochondrial 16S rRNA and COI obtained with CAOS-analyzer. Both the position in the alignments and the base letter are included. Only diagnostics with values of 1.00 are included (pure diagnostics). Note that Churchill et al. (2013) were unsuccessful in obtaining mt COI genotyes for <em>Glaucus bennettae</em> sp. nov.
