Abstract The nuclear ssu rRNA gene of several isopods (Crustacea, Peracarida) was sequenced to study its phylogenetic information content. Several areas had to be cut out of the alignment of 31 isopod sequences and selected outgroup arthropod sequences due to the lack of alignable patterns. The final alignment had 2,533 positions and 43 sequences. The length of the isopod nuclear ssu rRNA genes varies between 2,098 and 3,402 bp. In some clades the gene length increases; in others like the… Expand
The phylogenetic position of the Isopoda in the Peracarida (Crustacea: Malacostraca)
TLDR
The 18S data alone are inadequate at this phylogenetic level and the combined data provided novel hypotheses that require additional evidence from detailed morphological studies and DNA markers for confi rmation. Expand
MOLECULAR PHYLOGENY AND BIOGEOGRAPHY OF THE GENUS PSEUDOMMA (PERACARIDA: MYSIDA)
TLDR
DNA sequences from 18S rDNA and COI mtDNA are used to infer evolutionary history of northern groups of the deep-sea mysid genus Pseudomma, and an ancient presence of Pseudomonas longisquamosum in the Tethys Sea is suggested by phylogenetic structure, molecular clock considerations, and present distributions. Expand
The first complete mitochondrial genome of a parasitic isopod supports Epicaridea Latreille, 1825 as a suborder and reveals the less conservative genome of isopods
TLDR
The results cast doubt that Epicaridea Latreille, 1825 can be placed as an infraorder within the suborder Cymothoida, and Epicaridesa appears to also deserve subordinal rank. Expand
Basal position of two new complete mitochondrial genomes of parasitic Cymothoida (Crustacea: Isopoda) challenges the monophyly of the suborder and phylogeny of the entire order
TLDR
The results did not recover the suborders Cymothoida and Oniscidea Latreille, 1802 as monophyletic, with parasitic and free-living cymothoidans forming separate clades. Expand
Genetic evidence against monophyly of Oniscidea implies a need to revise scenarios for the origin of terrestrial isopods
TLDR
This work employed the highly conserved, nuclear protein-coding genes Sodium-Potassium Pump and Phosphoenolpyruvate Carboxykinase and produced a robust and fully resolved phylogenetic tree that offers strong evidence against the monophyly of Oniscidea. Expand
Peracarid monophyly and interordinal phylogeny inferred from nuclear small-subunit ribosomal DNA sequences (Crustacea: Malacostraca: Peracarida)
TLDR
The present phylogenetic study of peracarids is, to the authors' knowledge, the first that includes full-length nuclear (n) small-subunit (SSU) ribosomal DNA (rDNA) sequences for representatives of everyperacarid order. Expand
Searching factors causing implausible non-monophyly: ssu rDNA phylogeny of Isopoda Asellota (Crustacea: Peracarida) and faster evolution in marine than in freshwater habitats.
TLDR
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
Multiple rearrangements in mitochondrial genomes of Isopoda and phylogenetic implications.
TLDR
One of the first findings of homoplasy in mitochondrial gene order, namely a shared relative position of trnV in unrelated isopod lineages is reported, and modification in tRNAs and GC-skew inversion may be potentially fruitful subjects for future mt genome studies in a phylogenetic context. Expand
A species complex within the isopod genus Haploniscus (Crustacea: Malacostraca: Peracarida) from the Southern Ocean deep sea: a morphological and molecular approach
TLDR
Molecular data sets reveal detailed phylogenetic insights within the Haploniscus cucullus complex, supporting the monophyly of all species and show that both genes can be used as a marker for DNA taxonomy. Expand
Phylogenetic relationships of the family Sphaeromatidae Latreille, 1825 (Crustacea: Peracarida: Isopoda) within Sphaeromatidea based on 18S-rDNA molecular data.
TLDR
In the analyses the Sphaeromatidae are shown to be unequivocally monophyletic, contrary to the morphology-based analysis by A. Brandt and G. Poore in 2003, which found the family to be paraphyletic. Expand

Phylogenetic Study of Cirripedes and Selected Relatives (Thecostraca) Based on 18s Rdna Sequence Analysis
TLDR
It is concluded that the Thecostraca, represented here by the subclasses Ascothoracida and Cirripedia (the latter including the Acrothoracica, Rhizocephala, and Thoracica), is a monophyletic taxon. Expand
Origin and phylogeny of metazoans as reconstructed with rDNA sequences.
TLDR
Today, students of zoology will find a large number of incompatible dendrograms of the major groups of metazoans in textbooks and articles inferred from rDNA alignments, the major source of uncertainty in comparative morphology. Expand
Parasites of crustaceans (Isopoda: Bopyridae) evolved from fish parasites: Molecular and morphological evidence
TLDR
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
Limitations of Metazoan 18S rRNA Sequence Data: Implications for Reconstructing a Phylogeny of the Animal Kingdom and Inferring the Reality of the Cambrian Explosion
TLDR
The 18S rRNA molecule is an unsuitable candidate for reconstructing the evolutionary history of all metazoan phyla, and the polytomies cannot be used as a single or reliable source of evidence to support the hypothesis of a Cambrian explosion. Expand
Effects of nucleotide sequence alignment on phylogeny estimation: a case study of 18S rDNAs of apicomplexa.
TLDR
This empirical study inferred phylogenetic trees for 43 species of the Apicomplexa and 3 of Dinozoa based on complete small-subunit rDNA sequences using six different multiple-alignment procedures, and concluded that the helical regions are the most informative. Expand
PHYLOGENETIC RELATIONSHIPS OF CRUSTACEANS WITH FOLIACEOUS LIMBS: AN 18S rDNA STUDY OF BRANCHIOPODA, CEPHALOCARIDA, AND PHYLLOCARIDA
TLDR
Results strongly support three clades among the crustacean ingroup: a branchiopod clade, a (cephalocarid + copepod)Clade, and a malacostracan clade that includes the phyllocarids leptostracans Nebalia sp. Expand
Strengths and limitations of molecular sequence comparisons for inferring the phylogeny of the major groups of fishes
TLDR
Evaluation of studies using globins, parvalbumins, insulin, 28s ribosomal RNA, and portions of two mitochondria1 genes reveals some of the difficulties encountered in reconstructing ancient divergences within the fishes, including unequal rates of evolution. Expand
Evolutionary origin of whiteflies (Hemiptera: Sternorrhyncha: Aleyrodidae) inferred from 18S rDNA sequences
Phylogenetic analysis of 18S rDNA nucleotide sequences of hemipteran exemplars shows Sternorrhyncha (psyllids, whiteflies, aphids and scales) is monophyletic and forms a sister group to all otherExpand
Phylogeny of Selected Maxillopodan and Other Crustacean Taxa Based on 18S Ribosomal Nucleotide Sequences: A Preliminary Analysis
TLDR
The analyses suggest that acrothoracicans diverged very early from the cirripede line and are not derived from a lepadomorph-like ancestor; branchiurans are not related to either copepods or thecostracans but are closely allied with pentastomes; and the Maxillopoda, broadly defined, is not a monophyletic taxon.

Data Set Incongruence and the Phylogeny of Crocodilians
TLDR
Three hypotheses of crocodilian phylog- eny were evaluated using combined parsimony analysis, separate parsimony analyses, and eval- uation of uncombinable data and the (alligatorids(crocodylids(Gflinfl/zs, Tomistoma))) hypothesis of crocodian relationships was best supported. Expand
