Background Invertebrate nervous systems are highly disparate between different taxa. This
is reflected in the terminology used to describe them, which is very rich and often confusing …

Remipedes are a small and enigmatic group of crustaceans, first described only 30 years

The relationships of crustaceans and hexapods (Pancrustacea) have been much discussed
and partially elucidated following the emergence of phylogenomic data sets. However …

Bosmina longirostris is a small-bodied, filter-feeding cladoceran. The species is widely
distributed throughout the world in temperate and tropical climates, where it persists in all …

Understanding the evolution of Tetraconata or Pancrustacea—the clade that includes
crustaceans and insects—requires a well-resolved hypothesis regarding the relationships …

Molecular studies have enlightened our understanding of freshwater zooplankton
biogeography, yet questions remain regarding the scale and commonality of geographic …

Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and
recommendations governing phylogenetic nomenclature. Nearly 300 clades-lineages of …

Implied weighting, a method for phylogenetic inference that actively seeks to downweight
supposed homoplasy, has in recent years begun to be widely utilized in palaeontological …

The order Calanoida includes some of the most successful planktonic groups in both marine
and freshwater environments. Due to the morphological complexity of the taxonomic …
