evolutionary relationships of the octopodid genus Thaumeledone ( Cephalopoda : Octopodidae ) from the Southern

  title={evolutionary relationships of the octopodid genus Thaumeledone ( Cephalopoda : Octopodidae ) from the Southern},
  author={Jan M. Strugnell and Martin A. Collins and A. Louise Allcock},
Recent trawling in the Southern Ocean has yielded individuals of a number of species of the deep sea octopod genus Thaumeledone. This paper provides the first molecular study of the genus, employing molecular sequences from five mitochondrial (12S rDNA, 16S rDNA, COI, COIII, cytochrome oxidase b) and a single nuclear gene (rhodopsin) and includes representatives of each of the known Southern Ocean species. Thaumeledone rotunda, believed to be circumpolar in distribution and found in relatively…

Molecular phylogeny of the benthic shallow-water octopuses (Cephalopoda: Octopodinae).

A molecular phylogeny of the Octopoda (Mollusca: Cephalopoda) evaluated in light of morphological evidence.

In this paper we examine the phylogenetic relationships of the Octopoda utilizing molecular sequence data from the cytochrome c oxidase subunit I (COI) gene and compare results from analyses of

A cladistic reassessment of octopodid classification

This analysis examines methods that have contributed to octopodid classifications from a cladistic perspective that emphasizes the recognition of monophyletic groups, and applies parsimony algorithms to the data set reported by Voss (1988a) for the Octopodidae.

Genetic studies have revealed that species defined by morphological characters are complexes of cryptic or sibling species, which is consistent with the diversity and distribution of marine and terrestrial taxa having been strongly influenced by geological and climatic cooling events over the last 70 years.

An accurately resolved gene tree may not be congruent with the species tree because of lineage sorting of ancestral polymorphisms, but a survey of mtDNA‐haplotype diversity in 34 species of birds indicates that coalescence is generally very recent, which suggests that coalescent times are typically much shorter than internodal branch lengths of the species Tree, and that sorting of mt DNA lineages is not likely to confound the species trees.

Guidelines for taxonomic descriptions of cephalopod species

These guidelines or standards include specific requirements for descriptive characters of species within the Orders Sepioidea, Teuthoidea and Octopoda as well as general information, e.g., synonymy, locality, etc.

DNA primers for amplification of mitochondrial cytochrome c oxidase subunit I from diverse metazoan invertebrates.


Evolution, weighting, and phylogenetic utility of mitochondrial gene sequences and a compilation of conserved polymerase chain reaction primers

Molecular processes are reviewed, the correction of genetic distances and the weighting of DNA data are discussed, and an assessment of the phylogenetic usefulness of specific mitochondrial genes is provided.
