Genetic structure of harbour porpoise Phocoena phocoena populations in the northwest Atlantic based on mitochondrial and nuclear markers
The harbour porpoise, Phocoena phocoena, experiences high levels of nonnatural mortality owing to interactions with commercial fisheries throughout its range. To accurately evaluate the significance…

The limitations of mitochondrial gene barcoding in the sub‐class Octocorallia, a large, diverse, and ecologically important group of anthozoans, are examined, finding a COI’+ igr1 +‰msh1 barcode nonetheless represents a valuable addition to the depauperate set of characters available for octocoral taxonomy.
A molecular phylogenetic analysis of the Octocorallia (Cnidaria: Anthozoa) based on mitochondrial protein-coding sequences.
Geographic and bathymetric patterns of mitochondrial 16S rRNA sequence divergence among deep-sea amphipods, Eurythenes gryllus
Analysis of DNA sequence diversity in E. gryllus indicates genetic homogeneity among sites within the same depth zone at the scale of ocean basins; and genetically divergent, cryptic taxa distributed at different depths, with the greatest diversity in the bathyal zone.
Molecular phylogenetic analyses of shallow-water Caribbean octocorals
Octocorals, especially gorgonians, are conspicuous on Caribbean coral reefs, but there is no consensus regarding species relationships. Mitochondrial protein-coding genes [NADH-dehydrogenase subunits…
Phylogenetic relationships within the Octocorallia (Cnidaria: Anthozoa) based on nuclear 18S rRNA sequences
Using nuclear 18S’rRNA sequences for 41 species of octocorals, the validity of the historical ordinal divisions and the current subordinal divisions within the subclass Octocorallia were addressed and the phylogenetic affinities of the species D. paucispina were explored.
Phylogenetic relationships within the class Anthozoa (phylum Cnidaria) based on nuclear 18S rDNA sequences.
The 18S rRNA gene has sufficient phylogenetic signal, however, to distinguish among the major groupings within the Class Anthozoa, and this information is used to suggest relationships for the enigmatic taxa Dactylanthus and Dendrobrachia.
Phylogenomic Analyses Support Traditional Relationships within Cnidaria
Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well…
Use of RAD sequencing for delimiting species
Despite an impressive decrease in the number of homologous loci across clades, RAD data helped to fine-tune the interpretations of classical mitochondrial markers used in octocoral species delimitation, and discover previously undetected diversity.
Molecular phylogenetic insights into the evolution of Octocorallia: a review.
Emerging next-generation genomic-sequencing technologies offer the best hope for a breakthrough in the understanding of phylogenetic relationships and of evolution of morphological traits in Octocorallia.
