Comparative transcriptomics in Syllidae (Annelida) indicates that posterior regeneration and regular growth are comparable, while anterior regeneration is a distinct process [PDF]

BMC Genomics, 2019
Background Annelids exhibit remarkable postembryonic developmental abilities. Most annelids grow during their whole life by adding segments through the action of a segment addition zone (SAZ) located in front of the pygidium.

Gaps and Data Ambiguities in DNA Reference Libraries: A Limiting Factor for Molecular-Based Biodiversity Assessments Using Annelids as a Case Study. [PDF]

Ecol Evol
Regional DNA reference libraries are crucial for molecular biodiversity assessments, yet they remain incomplete, limiting their effectiveness. Using annelids from the Arabian Peninsula as a case study, we identified considerable gaps in species coverage and minimal representation in public databases.

Macroid Formation in <i>Salmacina stellaebayensis</i> n. sp. From Mauritania's Baie de l'Étoile With New Insights on Mitogenome Evolution in Serpulidae (Annelida). [PDF]

Ecol Evol
We describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.

Regeneration of Lumbriculus variegatus requires post-amputation production of reactive oxygen species. [PDF]

Dev Growth Differ
In many animal species, regeneration requires reactive oxygen species (ROS), but it is unknown if ROS are needed for annelid regeneration. We observed rapid accumulation of ROS at the amputation site of the annelid Lumbriculus variegatus. Inhibiting ROS production impaired regeneration, arguing for a phylogenetically ancient involvement of ROS in ...

Multi-Tool Marine Metabarcoding Bioassessment for Baselining and Monitoring Species and Communities in Kelp Habitats. [PDF]

Mol Ecol Resour
ABSTRACT The astonishing biological diversity found in Californian kelp forests requires efficient and robust monitoring tools to better understand ecological trends and mitigate against loss or disruption of ecosystem services due to human pressure and climate changes.

On the Diversity of Phyllodocida (Annelida: Errantia), with a Focus on Glyceridae, Goniadidae, Nephtyidae, Polynoidae, Sphaerodoridae, Syllidae, and the Holoplanktonic Families

Diversity, 2021
Phyllodocida is a clade of errantiate annelids characterized by having ventral sensory palps, anterior enlarged cirri, axial muscular proboscis, compound chaetae (if present) with a single ligament, and of lacking dorsolateral folds.

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO₂ vent of Ischia, Italy. [PDF]

Integr Zool
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

Ecology of Syllidae (Annelida: Polychaeta) from shallow rocky environments in the Cantabrian Sea (South Bay of Biscay)

Scientia Marina, 2006
The syllids inhabiting 12 hard bottom macrobenthic habitats were studied. A total of 38 species belonging to 19 genera were identified. Differences in density, species richness, and diversity among habitats were analysed, as well as the relationships ...

Final report : benthic samples taken from the Padre Island National Seashore [PDF]

, 1992
From March 1989 through January 1992 sediment samples were taken from subtidal areas within the boundary of the Padre Island National Seashore. These samples were taken as part of a large multidisciplinary study to determine how a hot, hypersaline ...

Loss of nervous system complexity – Morphological analyses shed light on the neuronal evolution in Myzostomida (Annelida)

Acta Zoologica, Volume 104, Issue 4, Page 633-646, October 2023., 2023
Abstract Myzostomida are putatively nested within the errant Annelida and exhibit a unique morphology. The latter fact might possibly be related to their long host‐dependent radiation. Hence, an incomplete segmentation, lack of prominent sensory structures in adults and a dorso‐ventrally flattened body are just some examples.
