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

open access: goldZoosystematics 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 ...

Additional new species of marine annelids from Clipperton Island (Nereididae: Pilargidae: Sabellariidae)

open access: greenEuropean Journal of Taxonomy
We herein present three additional new species of marine annelids collected during the Expédition Clipperton (Dec. 2004–Apr. 2005). A new species of nereidid polychaete, Perinereis hourdezi sp. nov. differs from P.

Gametogenesis of Nypha Palm Worm Namalycastis rhodochorde (Polychaeta: Nereididae)

open access: yesJurnal Ilmu Dasar, 2010
The Nypha Palm Worm Namalycastis rhodochorde has been used as bait for fishing in Pontianak. Culturing the worm is one potential effort for its commercialization as well as to overcome the overexploitation of the worm which also brings about the ...

Geographic Variation in Diet and Genetic Connectivity of Populations of the Widespread Predatory Cone Snail <i>Conus miliaris</i>. [PDF]

open access: yesEcol Evol
We examined patterns of dietary and genetic variation of a broadly distributed, Indo‐West Pacific cone snail at four sites in French Polynesia and compared them to populations at Guam, American Samoa, and Rapa Nui. Our results indicate that populations at French Polynesia possess broad and overlapping diets that are most similar to those of Rapa Nui ...

Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification. [PDF]

open access: yesMol Ecol
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

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

open access: yesEcol 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.

Revision of Sinonereis Wu & Sun, 1979 (Annelida: Nereididae) [PDF]

open access: greenZoosystema, 2019
The genus SinonereisWu & Sun, 1979 and the species Sinonereis heteropodaWu & Sun, 1979 were described from Chinese waters, based on only epitokous specimens with modified dorsal cirri in chaetigers 5-7 and bare pharynx. In the same publication, another species based on only atokes was described, Nicon sinicaWu & Sun, 1979. We show that N.

Molecular phylogeny of the Lecudinoidea (Apicomplexa): A major group of marine gregarines with diverse shapes, movements and hosts. [PDF]

open access: yesJ Eukaryot Microbiol
Abstract Gregarine apicomplexans are ubiquitous endosymbionts of invertebrate hosts. Despite their ecological and evolutionary importance, inferences about the phylogenetic relationships of major gregarine groups, such as the Lecudinidae and Urosporidae, have been hindered by vague taxonomic definitions and limited molecular and morphological data.
