A phylogenomic approach to resolve the arthropod tree of life.
TLDR
It is shown that phylogenomic data can substantially advance the understanding of arthropod evolution and resolve several conflicts among existing hypotheses.

Parametric and non-parametric masking of randomness in sequence alignments can be improved and leads to better resolved trees
TLDR
Alignment masking improves signal-to-noise ratio in multiple sequence alignments prior to phylogenetic reconstruction, and should routinely be used to improve tree reconstructions.

The brain of the Remipedia (Crustacea) and an alternative hypothesis on their phylogenetic relationships.
TLDR
A phylogenetic analysis limited to brain anatomy across the Mandibulata strongly contradicts the prevailing hypothesis that the Remipedia are a basal, ancestral crustacean group but instead argues in favor of a remipede-malacostracan-hexapod clade and most likely a sister-group relationship of Remipedia and Malacstraca.

Visualizing differences in phylogenetic information content of alignments and distinction of three classes of long-branch effects
TLDR
It is shown that tree topologies and popular support values do not show existing differences in data quality and an exploratory analysis of the signal to noise ratio can be conducted with split decomposition methods.

Can comprehensive background knowledge be incorporated into substitution models to improve phylogenetic analyses? A case study on major arthropod relationships
TLDR
Although the split-decomposition network indicated a high noise content in the data set, measures were able to both improve the analyses and give causal explanations for some incongruities mentioned from analyses of rRNA sequences, however, misleading effects did not completely disappear.

Multiple origins of deep-sea Asellota (Crustacea: Isopoda) from shallow waters revealed by molecular data
TLDR
The molecular data support the monophyly of most deep-sea families and give evidence for a multiple colonization of the deep sea by at least four major lineages of asellote isopods.

Molecular species identification of Central European ground beetles (Coleoptera: Carabidae) using nuclear rDNA expansion segments and DNA barcodes
TLDR
The results confirm that the analysed nuclear ribosomal expansion segments in combination constitute a valuable and efficient supplement for classical DNA barcoding to avoid potential pitfalls when only mitochondrial data are being used.

AliGROOVE – visualization of heterogeneous sequence divergence within multiple sequence alignments and detection of inflated branch support
TLDR
The AliGROOVE approach has the potential to identify single taxa or subsets of taxa which show predominantly randomized sequence similarity in comparison with other taxa in a multiple sequence alignment and allows to evaluate the reliability of node support in a novel way.

Checklist of the terrestrial isopods of the new world (Crustacea, Isopoda, Oniscidea)
A check-list of all the American Oniscidea known to the authors and their quotation in literature is presented. The species account comprises notes on species' distribution and a revised synonymy. As…

THE SCUTOCOXIFERA TAX. NOV. AND THE INFORMATION CONTENT OF NUCLEAR SSU RDNA SEQUENCES FOR RECONSTRUCTION OF ISOPOD PHYLOGENY (PERACARIDA: ISOPODA)
TLDR
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.
