Mitochondrial genome of the freshwater annelid Manayunkia occidentalis (Sabellida: Fabriciidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
Here, we report the 15,103 bp mitochondrial genome of the freshwater fabriciid tubeworm Manayunkia occidentalis. We recovered 13 protein-coding genes, 2 rRNA, and 22 tRNA. The gene order is consistent with the conserved pattern observed in most annelids.

Modelling of climatic tolerances of three earthworm species; Satchellius mammalis, Lumbricus friendi and Lumbricus festivus using Maximum Entropy Modeling [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2022
Earthworm distributions are poorly known and individual species climatic tolerances, even less so. This paper sets out to use three species with a mainly Anglo-French distribution to test out whether using Maximum Entropy Modelling (Maxent) could be ...

Three-dimensional reconstruction of the F-actin musculature of Dorvillea kastjani (Dorvilleidae, Polychaeta) by means of phalloidin-labelling and cLSM

open access: yesScientia Marina, 2006
This paper is part of a series investigating the muscular architecture of various “Polychaeta”, aiming to ascertain the presence of circular muscles in the body wall, which have recently been thought to be lacking more often than hitherto known.

First Record of Bioluminescence in a Sipunculan Worm

open access: yesFrontiers in Marine Science, 2021
During a search for bioluminescent marine annelids around the island of Carrie Bow Cay, Belize, we discovered bioluminescence in the sipunculan worm Nephasoma pellucidum. The identification of N. pellucidum was verified by DNA barcoding of ∼650 bp of the

A bioturbation classification of European marine infaunal invertebrates [PDF]

open access: yes, 2013
Bioturbation, the biogenic modification of sediments through particle reworking and burrow ventilation, is a key mediator of many important geochemical processes in marine systems.

Population dynamics of free-swimming Annelida in four Dutch wastewater treatment plants in relation to process characteristics [PDF]

open access: yes, 2008
Free-swimming Annelida occasionally occur in very high densities in WWTPs (WasteWater Treatment Plants) and are nowadays applied for waste sludge reduction, but their growth is uncontrollable.

Digging the diversity of Iberian bait worms Marphysa (Annelida, Eunicidae)

open access: yesPLoS ONE, 2020
During a visit to polychaete–rearing facilities in the vicinity of Bay of Cádiz (SW Iberian Peninsula, Atlantic Ocean), we sampled two populations of Marphysa (Annelida, Eunicidae) originally occurring at nearby intertidal soft bottoms, one being more ...

First record of the exotic earthworm Metaphire bahli (Gates, 1945) (Oligochaeta: Megascolecidae) from India [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2019
The occurrence of the exotic earthworm species Metaphire bahli (Gates, 1945) of the family Megascolecidae is recorded for the first time from India. Specimens were collected from the Alappuzha District of Kerala State.

Within-family plasticity of nervous system architecture in Syllidae (Annelida, Errantia)

open access: yesFrontiers in Zoology, 2020
Background The ground pattern underlying the nervous system of the last common ancestor in annelids was long thought to be settled, consisting of a dorsal brain, circumoesophageal connectives and a subepithelial, ladder-like ventral nerve cord with ...
