The complete sequences and gene organisation of the mitochondrial genomes of the heterodont bivalves Acanthocardia tuberculata and Hiatella arctica – and the first record for a putative Atpase…
The two mt-genomes reported here add to and underline the high variability of gene order and presence of duplications in bivalve and molluscan taxa and help resolve phylogenetic patterns at lower taxonomic levels. Expand
Molecular phylogeny of Anomalodesmata (Mollusca: Bivalvia) inferred from 18S rRNA sequences
Tests of various alternative topologies showed that all are significantly longer but optimal likelihood trees with monophyletic carnivorous taxa and/or Thraciidae are not significantly less likely andPalaeontological data and homology decisions for selected characters are evaluated in the light of the molecular trees.

THE SCUTOCOXIFERA TAX. NOV. AND THE INFORMATION CONTENT OF NUCLEAR SSU RDNA SEQUENCES FOR RECONSTRUCTION OF ISOPOD PHYLOGENY (PERACARIDA: ISOPODA)
The results of maximum parsimony analyses are congruent with major aspects of earlier hypotheses on isopod phylogeny and a major monophyletic group found in the molecular phylogenies and also supported by distinct morphological characters is named Scutocoxifera tax. Expand
Parasites of crustaceans (Isopoda: Bopyridae) evolved from fish parasites: Molecular and morphological evidence
It is proposed to give up the classification of these parasites as a separate suborder "Epicaridea", to name the taxon "Bopyridae", which should have the same rank as the sistertaxon, the family Cymothoidae, to reconstruct an evolutionary scenario. Expand
Reconstructing the Anomalodesmata (Mollusca: Bivalvia): morphology and molecules
The results of an enhanced analysis of 32 anomalodesmatan species indicate the need for a re-distribution of the families traditionally placed in the Thracioidea and Pandoroidea into a 'thraciid' lineage and a 'lyonsiids' lineage. Expand
The complete sequence and gene organization of the mitochondrial genome of the gadilid scaphopod Siphonondentalium lobatum (Mollusca).
The deep molluscan phylogeny is probably beyond the resolution of mitochondrial protein sequences, and assessing the phylogenetic signal in gene order data requires a much larger taxon sample than is currently available, given the exceptional diversity of this character set in the Mollusca. Expand
Molecular phylogeny of Scaphopoda (Mollusca) inferred from 18S rDNA sequences: support for a Scaphopoda–Cephalopoda clade
The 18S rDNA data reject the Diasoma in favour of a Scaphopoda–Cephalopoda clade as proposed in the helcionellid concept, and there is no support for the families Dentaliidae and Gadilidae. Expand
Searching factors causing implausible non-monophyly: ssu rDNA phylogeny of Isopoda Asellota (Crustacea: Peracarida) and faster evolution in marine than in freshwater habitats.

Parametric boostrapping in combination with spectra indicates that a tree model cannot explain the data and that monophyly of the Asellota should not be rejected even though many topologies do not recover this taxon. Expand
