Phylogenomics underpins a stable and mostly well-resolved hypothesis for the
interrelationships of extant arthropods. Exceptionally preserved fossils are integrated into …

Spiders (Araneae) make up a remarkably diverse lineage of predators that have
successfully colonized most terrestrial ecosystems. All spiders produce silk, and many …

Phylogenomic subsampling is a procedure by which small sets of loci are selected from
large genome-scale data sets and used for phylogenetic inference. This step is often …

Deciphering the evolutionary relationships of Chelicerata (arachnids, horseshoe crabs, and
allied taxa) has proven notoriously difficult, due to their ancient rapid radiation and the …

Long-branch attraction is a systematic artifact that results in erroneous groupings of fast-
evolving taxa. The combination of short, deep internodes in tandem with long-branch …

Despite significant advances in invertebrate phylogenomics over the past decade, the
higher-level phylogeny of Pycnogonida (sea spiders) remains elusive. Due to the …

Arachnida is an exceptionally diverse class in the Arthropoda, consisting of 20 orders and
playing crucial roles in the terrestrial ecosystems. However, their interordinal relationships …

The majority of extant arachnids are terrestrial, but other chelicerates are generally aquatic,
including horseshoe crabs, sea spiders, and the extinct eurypterids. It is necessary to …

Six-state amino acid recoding strategies are commonly applied to combat the effects of
compositional heterogeneity and substitution saturation in phylogenetic analyses. While …

Gastropods have survived several mass extinctions during their evolutionary history
resulting in extraordinary diversity in morphology, ecology, and developmental modes …
