Phylogenomic analyses reveal a Palaeozoic radiation and support a freshwater origin for clitellate annelids

open access: yesZoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020
Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...

Mitochondrial Genome Evolution in Annelida—A Systematic Study on Conservative and Variable Gene Orders and the Factors Influencing its Evolution [PDF]

open access: yes, 2023
The mitochondrial genomes of Bilateria are relatively conserved in their protein-coding, rRNA, and tRNA gene complement, but the order of these genes can range from very conserved to very variable depending on the taxon.

Comparing Sediment and Water eDNA Metabarcoding for Monitoring Aquatic Biodiversity in a Plateau Lake

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Using multi‐locus eDNA metabarcoding of sediment and water samples collected from a plateau lake, this study systematically compared taxonomic diversity and community composition between the two sample types across the tree of life from archaea to mammals.
