Time-series studies of arctic marine ecosystems are rare. This is not surprising since polar regions largely only accessible by means expensive modern infrastructure and instrumentation. In 1999, the Alfred Wegener Institute, Helmholtz-Centre for Polar Marine Research (AWI) established LTER (Long-Term Ecological Research) observatory HAUSGARTEN crossing Fram Strait at about 79° N. Multidisciplinary investigations covering all parts open-ocean ecosystem carried out a total 21 permanent...
Abstract Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field on Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of LCVF has not yet been published, hindering inclusion biogeographic analyses fauna. There is an urgent need to understand diversity, spatial distribution ecosystem function biological communities along AMOR, which will inform environmental impact assesments future deep-sea mining activities...
Deep-sea research is a very active field in which environments such as hydrothermal vents are of particular interest because they host unique and often endemic fauna. In this paper, we describe new species the genus Caulleriella Chamberlin, 1919 (Annelida, Cirratulidae Ryckholt, 1851) report presence Raricirrus arcticus Buzhinskaja & Smirnov, 2017 at Loki’s Castle vent (LCVF), first detailed since original description. Both illustrated similarities with closely related discussed. We...

A new species of Lumbrineridae, Helmutneris vadum n. sp., is described from shallow waters near Lizard Island, Great Barrier Reef, Queensland, Australia. The differs two other known by having bidentate maxillae III and no ventral limbate chaetae. Sequences the fragments COI 16S rDNA for specimens including holotype are deposited in GenBank. key three to date provided.
In this study, we analyze the current state of knowledge on extant Eunicida systematics, morphology, feeding, life history, habitat, ecology, distribution patterns, local diversity and exploitation. is an order Errantia annelids characterized by presence ventral mandibles dorsal maxillae in a muscularized pharynx. The origin dates back to late Cambrian, peaks jaw morphology number families are Ordovician. Species richness heterogeneous among seven recent families, with more than half valid...
The composition, taxonomic structure and distribution patterns of bathyal benthic fauna the northern Mid-Atlantic Ridge between Azores southern tip Reykjanes were studied from specimens collected on ‘G.O. Sars MAR–ECO’ expedition in July 2004. Material was obtained 16 Campelen 1800 trawls taken north (42°N) two areas around Charlie-Gibbs Fracture Zone (CGFZ) (51°N 53°N) at depths 1237–3527 m. A total 192 species recorded. Overall MAR–ECO dominated by echinoderms (49.5% sampled), sponges...
Abstract Background Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over last 150 years. In May–June 2017, IN2017_V03 expedition RV Investigator sampled LBA communities along slope and abyss Australia’s eastern margin mid-Tasmania (42°S) Coral Sea (23°S), particular emphasis on describing analysing patterns biodiversity that occur within newly...
Abstract Taxonomy based on morphology can be difficult. The challenges arise from different sources such as poor original descriptions, new records inadequate knowledge, uncritical application of general assumptions or presence complexes cryptic species. One example problematic taxonomy is the genus Diopatra Audouin & Milne Edwards, 1833 (Onuphidae, Annelida) and within it two species aciculata D. neapolitana . exhibit great similarity between them casting doubts their validity separate...
Abstract Background Modern integrative taxonomy-based annelid species descriptions are detailed combining morphological data and, since the last decades, also molecular information. Historic often comparatively brief lacking such detail. Adoptions of names from western literature in past led to assumption cosmopolitan ranges for many species, which, cases, were later found include cryptic or pseudocryptic lineages with subtle differences. Natural history collections and databases can aid...
In Australia, the deep-water (bathyal and abyssal) benthic invertebrate fauna is poorly known in comparison with that of shallow (subtidal shelf) habitats. Benthic from deep eastern Australian margin was sampled systematically for first time during 2017 RV ‘Investigator’ voyage ‘Sampling Abyss’. Box core, Brenke sledge, beam trawl samples were collected at one-degree intervals Tasmania, 42°S, to southern Queensland, 24°S, 900 4800 m depth. Annelids identified by taxonomic experts on...
Analysis of 55 morphological characters yielded a phylogenetic reconstruction the Diopatra complex, currently including three genera (Diopatra, Epidiopatra, and Paradiopatra). The results reject monophyletic status complex all analysed. It is suggested that several parallel independent events paedomorphic evolution took place within Paradiopatra, which led to recognition two artificial Epidiopatra Notonuphis. following taxonomic revisions are proposed: (1) as junior synonym Diopatra; (2)...
Onuphid polychaetes are tubicolous marine worms commonly reported worldwide from intertidal areas to hadal depths. They often dominate in benthic communities and have economic importance aquaculture recreational fishing. Here we report the phylogeny of family Onuphidae based on combined analyses nuclear (18S rDNA) mitochondrial (16S genes. Results Bayesian Maximum Likelihood supported monophyly its traditional subdivision into two monophyletic subfamilies: Onuphinae Hyalinoeciinae. Ten 22...
Diopatra Audouin & Milne-Edwards, 1833 is a species rich genus that common in tropical and subtropical regions. The readily identified by its striking, spiral branchiae, but identification has historically been challenging due to high variation diagnostic characters used. This study aims reconstruct the phylogeny of with molecular markers assess diversity West African delimitation programs bPTP BPP.

In this work, the diversity of genus Orbiniella in Nordic Seas and North Atlantic waters south Iceland is studied based on analyses molecular markers (mitochondrial COI, 16S rDNA nuclear ITS2) morphological characters. Our results showed presence at least five genetic lineages material which could also be morphologically identified by their segmental annulation patterns, number shape acicular spines, length pygidial lobes. The species name petersenae assigned to one restricting its...
Abstract Development of Mooreonuphis stigmatis, one the dominant polychaete species in intertidal soft-bottom community False Bay (San Juan Island, Washington, USA) has been studied from 5-chaetiger stage to adult utilizing SEM techniques. Clearly lecithotrophic larvae develop inside parental tubes until at least 17-chaetiger stage. The earliest observed demonstrated reduced trochal ciliation. Description development various ciliated sensory organs is provided. prostomial and peristomial...

Abstract The polychaete macrofauna of the northern Mid-Atlantic Ridge between Azores (42°N) and southern tip Reykjanes (54°N) was studied based on material obtained during R/V G.O. Sars MAR-ECO cruise in 2004 two RRS James Cook ECOMAR cruises 2007 2009. Polychaetes were collected from 28 trawl catches at depths 981 to 3527 m. In total, 457 specimens identified 34 species-level taxa belonging 18 families. Of species, 22 could be known species (4 with reservation). Only 12 represented more...
