Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha [PDF]

open access: yes, 2013
BackgroundMolecular phylogenetic analyses have revealed that Hexapoda and Crustacea form a common clade (the Pancrustacea), which is now widely accepted among zoologists; however, the origin of Hexapoda remains unresolved.

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

open access: yesProceedings of the Royal Society B: Biological Sciences, 2018
Understanding the evolution of Tetraconata or Pancrustacea—the clade that includes crustaceans and insects—requires a well-resolved hypothesis regarding the relationships within and among its constituent taxa. Here, we assembled a taxon-rich phylogenomic

Water Interaction Type Affects Environmental DNA Shedding Rates of Terrestrial Mammal eDNA Into Surface Water Bodies

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
Although shedding rates for aquatic species are well studied, little is known about terrestrial mammal shedding rates in water. In this study, we quantify eDNA shedding rates from domestic dogs during various interactions with water bodies and find that defecation and crossing through water produce the highest shedding rates, highlighting direct water ...
