Diet variation of common smelt across a salinity gradient in coastal lakes on Rēkohu (Chatham Island)

New Zealand Journal of Marine and Freshwater Research, Volume 58, Issue 3, Page 404-421, September 2024.
ABSTRACT Sea level rise threatens ecosystem function in coastal lakes by increasing salinity and altering community composition. As mobile generalists, fish have considerable influence on the stability of a system by impacting trophic network structure.

On some Nereididae (Polychaeta) with new record for the Egyptian waters [PDF]

Egyptian Journal of Aquatic Biology and Fisheries, 2020
In the present study 18 Nereididae species have been recorded, belonging to 8 genera, in fouling samples taken during 2015 from Suez Canal, and during 2010 from Hurghada (Red Sea), and in sediment samples collected from the Suez Gulf in 2018, from Port Said, Rashid, from Damietta and Marina in 2013, and from El Dabaa in 2017.

Marine sediment infauna‐based environmental assessment using metabarcoding identifies potential impact indicator species

Environmental DNA, Volume 6, Issue 3, May–June 2024.
Intertidal infaunal community data are obtained via: (1) morphological identification of macroinvertebrates from sediment cores, (2) cytochrome c oxidase subunit I (COI) DNA metabarcoding of the same pooled macroinvertebrate specimens, and (3) 18S ribosomal RNA (18S) DNA metabarcoding of benthic meiofauna from small volume sediment surface scrapes.

The Nereid on the rise: Platynereis as a model system

EvoDevo, 2021
The Nereid Platynereis dumerilii (Audouin and Milne Edwards (Annales des Sciences Naturelles 1:195–269, 1833) is a marine annelid that belongs to the Nereididae, a family of errant polychaete worms.

Ocean deoxygenation caused non‐linear responses in the structure and functioning of benthic ecosystems

Global Change Biology, Volume 30, Issue 1, January 2024.
Over the past decades, there has been a gradual decline in global ocean oxygen concentrations due to climate change (ocean warming) and human activities (eutrophication). How this long‐term deoxygenation affects the macrobenthic communities and sediment biogeochemistry remain elusive.

Morphology, Phylogeny, and Evolution of the Rarely Known Genus Admetella McIntosh, 1885 (Annelida, Polynoidae) with Recognition of Four New Species from Western Pacific Seamounts

Journal of Zoological Systematics and Evolutionary Research, Volume 2024, Issue 1, 2024.
The polynoid genus Admetella constitutes a deep‐sea assemblage of polychaetes, notable for their large bodies adorned with antennal scales positioned dorsally to the bases of lateral antennae. Furthermore, the genus exhibits swimming proficiencies facilitated by elongated parapodia and flattened chaetae.

Description and phylogeny of Namalycastis jaya sp. n. (Polychaeta, Nereididae, Namanereidinae) from the southwest coast of India

ZooKeys, 2012
Namalycastis jaya sp. n. (Polychaeta: Nereididae: Namanereidinae) is described from the southern coast of Kerala in southwest India. One important characteristic feature of the species is the lack of notochaetae in all parapodia, a characteristic that it

Molecular systematics of Perinereis and an investigation of the status and relationships of the cultured species Perinereis wilsoni Glasby & Hsieh, 2006 (Annelida, Nereididae) [PDF]

Zoosystematics and Evolution
In this study, we conducted morphological and molecular analyses of Perinereis wilsoni, a species being considered for aquaculture in China. We found this species difficult to identify because of its close morphological similarity to the sympatric P ...

An immunocytochemical window into the development of Platynereis massiliensis (Annelida, Nereididae)

The International Journal of Developmental Biology, 2014
The nereidid annelid Platynereis dumerilii emerged as a well-understood model organism. P. dumerilii and P. massiliensis are sister taxa, which are morphologically indistinguishable as adults. Interestingly, they exhibit highly contrasting life-histories: while P. dumerilii is a gonochorostic species with planktonic feeding larvae, P. massiliensis is a

Marine biodiversity of Costa Rica: Class Polychaeta (Annelida)

Revista de Biología Tropical, 2004
Three hundred and thirty two species of polychaetes belonging to 50 families are reported for Costa Rica based on previously published reports. In a few families, available material was re-examined and appropriate changes in species identifications were ...
