ABSTRACT Peracarids are a large group of malacostracan crustaceans whose systematics and phylogeny are uncertain. The present phylogenetic study of peracarids is, to our knowledge, the first that includes full-length nuclear (n) small-subunit (SSU) ribosomal DNA (rDNA) sequences for representatives of every peracarid order. Sequence length varied substantially (1807–2746 base pairs), and two variable regions (V4 and V7) contained long expansion segments. Variable regions also exhibited… 

Phylogenetic Relationships of Tanaidacea (Eumalacostraca: Peracarida) Inferred from Three Molecular Loci

Results suggested that the monotypic Hargeria should be considered a junior synonym of Leptochelia, corroborating morphological evidence, in the first attempt at using molecular data to determine phylogenetic relationships of tanaidaceans.

Relationships of the Sphaeromatidae genera (Peracarida: Isopoda) inferred from 18S rDNA and 16S rDNA genes

The Sphaeromatids’ impressive exploitation of diverse habitats, in combination with diversity in female life history strategies and elaborate male combat structures, has resulted in extraordinary levels of homoplasy.

Relationships of the Sphaeromatidae genera ( Peracarida : Isopoda ) inferred from 18 S rDNA and 16 S rDNA genes

The Sphaeromatids’ impressive exploitation of diverse habitats, in combination with diversity in female life history strategies and elaborate male combat structures, has resulted in extraordinary levels of homoplasy.

Eumalacostracan phylogeny and total evidence: limitations of the usual suspects

Rate heterogeneity and conflict between data partitions mean that existing molecular and morphological evidence is unable to resolve a well-supported eumalacostracan phylogeny, and it will be necessary to look beyond the most commonly utilized sources of data to obtain a robust tree in the future.

Phylogenetic relationships of the family Sphaeromatidae Latreille, 1825 (Crustacea: Peracarida: Isopoda) within Sphaeromatidea based on 18S-rDNA molecular data.

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.

Tetraconatan phylogeny with special focus on Malacostraca and Branchiopoda: highlighting the strength of taxon-specific matrices in phylogenomics

A taxon-rich phylogenomic dataset focusing on crustacean lineages based solely on genomes and new-generation Illumina-generated transcriptomes, including 89 representatives of Tetraconata is assembled, which constitutes, to the authors' knowledge, the first phylogenomic study specifically addressing internal relationships of Malacostraca and Branchiopoda.

MOLECULAR PHYLOGENY AND BIOGEOGRAPHY OF THE GENUS PSEUDOMMA (PERACARIDA: MYSIDA)

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.

BRANCHIOPOD MONOPHYLY AND INTERORDINAL PHYLOGENY INFERRED FROM 18S RIBOSOMAL DNA

It is proposed that the taxonomic heading “Cladocera” include a new taxon, Cyclesthera, equal in rank to the Gymnomera, which corroborates views based on morphological comparisons that the cladoceran lineage arose from a cyclestherid-like ancestor.

First observations on the phylogeny of the families Gammaridae, Crangonyctidae, Melitidae, Niphargidae, Megaluropidae and Oedicerotidae (Amphipoda, Crustacea), using small subunit rDNA gene sequences

This study examines amphipod phylogeny based on small subunit (18S) rDNA sequence data and discusses the evolution of cephalothoracic apodemes in the light of other phylogenetic hypotheses resulting from molecular data.

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.

PHYLOGENETIC RELATIONSHIPS OF CRUSTACEANS WITH FOLIACEOUS LIMBS: AN 18S rDNA STUDY OF BRANCHIOPODA, CEPHALOCARIDA, AND PHYLLOCARIDA

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.

A V4 expansion segment is reported which exceeds the longest crustacean sequences known until now by more than 270 bp, indicating that all Antarctic species in this study form a monophyletic group which has probably derived from species with closest extant relatives in South America.

MITOCHONDRIAL GENES AND ISOPOD PHYLOGENY (PERACARIDA: ISOPODA)

These mitochondrial genes corroborate isopod clades previously recognized on morphological grounds, and in other instances, suggest relationships not previously proposed, i.e., valviferans had a sphaeromatid ancestor, and oniscids and sphaERomatids may be more closely related than previously thought.

28S rDNA evolution in the Eumalacostraca and the phylogenetic position of krill.

The phylogenetic position of one order within this class of Crustacea, the Euphausiacea, was investigated using 28S rDNA sequences from representatives of several malacostracan orders, and suggested that Euphasiacea are most closely related to the Mysida and not the Decapoda, as is generally thought.

An alternative phylogeny of peracarid crustaceans

The polyphyletic nature of the Peracarida is discussed and it is suggested that at least three independent lines of "peracaridan" radiation might have arisen from a pre-Carboniferous syncarid-Iike ancestral eumalacostracan.
