Reproductive morphology and redescriptions of some Neanthes Kinberg, 1865 (Annelida: Nereididae) species from the southeastern Asian seas, with comparative synoptic tables of accepted species

open access: yesThe European Zoological Journal, 2021
Neanthes Kinberg, 1865 is a speciose nereidid genus with some species exhibiting epitoky during the timing of reproduction. The epitokal morphology of males and females has long been agreed to be diagnostic to distinguish species.

A new southern record of the holopelagic annelid Poeobius meseres Heath, 1930 (Flabelligeridae) [PDF]

open access: yesBiodiversity Data Journal, 2020
The unusual holopelagic annelid Poeobius meseres Heath, 1930 (Flabelligeridae) was first collected from Monterey Bay, California, and has been subsequently recorded across the northern Pacific from Japan to the Gulf of California. Rare occurrences in the

Gyrochorte “highways” and their environmental significance in shallow-marine sediments [PDF]

open access: yesActa Palaeontologica Polonica, 2020
The reworking of a trace by a subsequently following organism represents a so-called sequorichnial behavior and leads to formation of a “burrowing highway”. Burrowing highways occur more frequently than assumed in the fossil record.

Searching for a Home Port in a Polyvectic World: Molecular Analysis and Global Biogeography of the Marine Worm Polydora hoplura (Annelida: Spionidae)

open access: yesBiology, 2023
The spionid polychaete Polydora hoplura Claparède, 1868 is a shell borer widely occurring across the world and considered introduced in many areas. It was originally described in the Gulf of Naples, Italy.

Mitochondrial genome of Pseudopotamilla reniformis (Annelida: Sabellidae)

open access: yesMitochondrial DNA. Part B. Resources, 2023
Here, we report the complete mitochondrial genome of sabellid Pseudopotamilla reniformis (Bruguière, 1789) (16,408 bp) and comprised of two ribosomal RNAs, the ubiquitous set of 13 protein-coding sequences, and 22 tRNAs. The order of protein-coding genes

Compositional and Functional Microbiome Variation Between Tubes of an Intertidal Polychaete and Surrounding Marine Sediment

open access: yesFrontiers in Marine Science, 2021
The decorator worm Diopatra cuprea, a tube-forming marine polychaete common to intertidal and shallow subtidal waters, modifies habitats it occupies through microreef construction and algal gardening.

First mitochondrial genomes of Capitellidae and Opheliidae (Annelida) and their phylogenetic placement

open access: yesMitochondrial DNA. Part B. Resources, 2022
The complete mitochondrial genomes of Notomastus sp. (15,776 bp) (Annelida: Capitellidae) and Armandia sp. (18,538 bp) (Annelida: Opheliidae) were assembled for the first time. A group II intron (303 bp) was found in cox1 of Notomastus sp. A phylogenetic

The first complete mitochondrial genome of the genus Dendronereis, represented by D. chipolini Hsueh, 2019 (Annelida, Nereididae) from Beibu Gulf, China

open access: yesMitochondrial DNA. Part B. Resources, 2022
The genus Dendronereis Peters, 1854 is characterized in the polychaete family Nereididae by its feather-shaped branchiae on the anterior segments. In this study, we present the first complete mitogenome of Dendronereis, represented by D. chipolini Hsueh,

Effects of temperature on in vitro sediment reworking processes by a gallery biodiffusor, the polychaete Neanthes virens [PDF]

open access: yes, 2004
Temperature-induced variations in bioturbation could affect sediment mixing processes in the marine benthic environment. In this study, sediment reworking by Neanthes virens (Sars), a widely distributed polychaete in muddy sand communities of northern ...
