Influence of the predatory polychaete Nephtys hombergii on the abundance of other polychaetes [PDF]

open access: yesMarine Ecology Progress Series, 1987
Negative relations between abundance of the predatory polychaete Nephtys hombergii and values for biornass and rate of increase in 2 of its prey species, the polychaetes Scoloplos armiger and Heteromastusfiliformis, are evident in long-term (18 yr) data from tidal flats in the westernmost part of the Wadden Sea.

Hidden in plain sight, Chaetopterus dewysee sp. nov. (Chaetopteridae, Annelida) – A new species from Southern California

open access: yesEuropean Journal of Taxonomy, 2020
We describe a long-unnamed Chaetopterus Cuvier, 1830 species from southern California, using a combination of DNA barcoding and detailed morphological investigation employing high-resolution X-ray microtomography (micro-CT). Chaetopterus dewysee sp. nov.

The complete mitochondrial genome of the marine feather duster, Bispira melanostigma (Annelida: Sabellidae)

open access: yesMitochondrial DNA. Part B. Resources, 2022
The marine feather duster, Bispira melanostigma (Schmarda, ), is a tube-dwelling annelid that contributes to ecological and biogeochemical processes in benthic communities. Due to the lack of scientific data, B.

Polychaete Diversity Related to Different Mesophotic Bioconstructions along the Southeastern Italian Coast

open access: yesDiversity, 2021
In the different mesophotic bioconstructions recently found along the Southeastern Italian coast, polychaetes have been proved to show high species richness and diversity, hitherto never investigated.

Molecular and Morphological Phylogenies of Spirorbinae (Serpulidae, Polychaeta, Annelida) and the Evolution of Brooding Modes

open access: yesDiversity
Spirorbinae, a ubiquitous group of marine calcareous tubeworms with a small body size as adults, have a fascinating diversity of brooding modes that form the basis for their taxonomic division into six tribes (traditionally subfamilies): in-tube ...

Assessment of trace element accumulation on the Tunisian coasts using biochemical biomarkers in Perinereis cultrifera

open access: yesScientia Marina, 2021
Our study aimed to evaluate the effect of trace element pollution in the polychaete Perinereis cultrifera (Grube, 1840) from two Tunisian coasts (the port of Rades, S1; and the Punic port of Carthage, S2).

Testing the potential for improving quality of sediments impacted by mussel farms using bioturbating polychaete worms

open access: yes, 2017
Biodeposits from farmed mussels severely influencethe biogeochemistry of sediments by increasing thelevels of organic matter (OM). Mitigation of suchnegative impacts is important for the developmentof sustainable aquaculture operations.

Macrofaunal contributions to benthic nutrient fluxes revealed by radium disequilibrium

open access: yesLimnology and Oceanography, EarlyView.
Abstract The benthic flux of nutrients underpins marine food webs, influences conditions for life in the oceans, and contributes to climatic feedback. Estimates of these fluxes' contributions to macro‐ and micronutrient cycles are, however, highly variable, generating significant uncertainty in biogeochemical models.

The complete mitochondrial genome of the polychaete, Marphysa tamurai (Eunicida, Eunicidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The study determined the first complete mitochondrial genome (mitogenome) of the polychaete, Marphysa tamurai. A total of 21,346 reads were generated by Illumina HiSeq2500 platform with an average depth of 175.97×. The mitogenome of M. tamurai was 15,163

Genetic features of the marine polychaete Sirsoe methanicola from metagenomic data

open access: yesFrontiers in Marine Science, 2023
The methane ice worm Sirsoe methanicola is the only marine polychaete species observed to colonize the methane hydrates of the Gulf of Mexico. Methane hydrates are ephemeral features of deep-sea cold seeps, and finding worm-colonized hydrates is rare ...
