Comparative Mitogenomics of Leeches (Annelida: Clitellata): Genome Conservation and Placobdella-Specific trnD Gene Duplication. [PDF]

PLoS ONE, 2016
Mitochondrial DNA sequences, often in combination with nuclear markers and morphological data, are frequently used to unravel the phylogenetic relationships, population dynamics and biogeographic histories of a plethora of organisms.

The genome sequence of the red compost earthworm, Lumbricus rubellus (Hoffmeister, 1843) [version 1; peer review: 2 approved]

Wellcome Open Research, 2023
We present a genome assembly from an individual Lumbricus rubellus (the red compost earthworm; Annelida; Clitellata; Haplotaxida; Lumbricidae). The genome sequence is 787.5 megabases in span.

Metabarcoding Close to Home: Songbird Nests as eDNA Aggregators for Trophic Ecology and Biodiversity Studies. [PDF]

Ecol Evol
We present a novel method for extracting eDNA from whole bird nests and a LNA blocking oligonucleotide designed to reduce metabarcoding reads from nest building sparrows. Metabarcoding of 22 nests from a montane sagebrush steppe ecosystem detected 126 species, primarily insects, including putative diet items, ectoparasites, and confirmed nest predators.

Ovaries of Tubificinae (Clitellata, Naididae) resemble ovary cords found in Hirudinea (Clitellata) [PDF]

Zoomorphology, 2010
The ultrastructure of the ovaries and oogenesis was studied in three species of three genera of Tubificinae. The paired ovaries are small, conically shaped structures, connected to the intersegmental septum between segments X and XI by their narrow end.

Comparison of Morphological and DNA-Based Identification Methods to Assess Earthworm (Clitellata: Lumbricidae) Diversity at 25 Permanent Soil Monitoring Sites in Germany. [PDF]

Ecol Evol
The present contribution should contribute to solving the problem of the time‐consuming and expensive identification of soil invertebrates in the standardised survey of soil organisms. Earthworms and soil were sampled at 25 sites; the animals were identified morphologically and by community DNA (comDNA) and environmental DNA (eDNA) metabarcoding, and ...

A histidine-rich extension of the mitochondrial F₀ subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria. [PDF]

FEBS Lett
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Exploring Barbronia species diversity and phylogenetic relationship within Suborder Erpobdelliformes (Clitellata: Annelida). [PDF]

PeerJ
Background Barbronia, a genus of freshwater macrophagous leeches, belongs to Erpobdelliformes (Salifidae: Clitellata: Annelida), and B. weberi, a well-known leech within this genus, has a worldwide distribution. However, the systematics of Barbronia have

Mitogenome of the blood feeding leech Haementeria acuecueyetzin (Hirudinida: Glossiphoniidae) from Tabasco, Mexico

Mitochondrial DNA. Part B. Resources, 2020
Here, we present the mitogenome of the blood feeding leech Haementeria acuecueyetzin (Hirudinida: Glossiphoniidae) based on specimens collected in Tabasco, Mexico.

Enchytraeus demutatus sp. nov. (Enchytraeidae, Oligochaeta) has characters hitherto unrecorded in the genus

Soil Organisms, 2019
A new species of enchytraeids with peculiar characters is described, Enchytraeus demutatus sp. nov. The species differs from all known species of Enchytraeus in features of the oesophageal appendages and the male efferent apparati.

Temporal niche dynamics of spreading native invertebrates underlie doubling of richness in pristine temperate streams. [PDF]

J Anim Ecol
Expanding native species of river macroinvertebrates mainly retained their original niches, with little evidence of niche shifts over the last 25 years. This suggests that species richness in pristine rivers increases due to enhanced ecosystem energy flow, relaxing interspecific competition and allowing it to carry more individuals and species ...
