Amphipod family distributions around Iceland
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)Amphipod crustaceans were collected at all 55 stations sampled with an epibenthic sledge during two IceAGE expeditions (Icelandic marine Animals: Genetics and Ecology) in 2011 and 2013. In total, 34 amphipod families and three superfamilies were recorded in the samples. Distribution maps are presented for each taxon along with a summary of the regional taxonomy for the group. Statistical analyses ... -
Amphipods and sea anemones, an update
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-02)We present an updated survey of the Amphipoda that live in association with sea anemones. These amphipods can be divided into four groups: 1) symbiotic amphipods using sea anemones mainly for protection, but feeding largely independently; 2) amphipods feeding on sea anemones, but not permanently associated; 3) symbiotic amphipods living permanently among the tentacles of the sea anemones; and 4) ... -
Exitomelita sigynae gen. et sp. nov. : a new amphipod from the Arctic Loki Castle vent field with potential gill ectosymbionts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)The newly discovered deep-sea hydrothermal vent field “Loki’s Castle” at 2,350 m depth at 70°N on the Knipovich Ridge north of the island Jan Mayen is the only known black smoker field from the Arctic Ridge system. This vent field holds a unique fauna clearly distinct from vent sites along the Mid-Atlantic Ridge south of Iceland. In addition to numerous maldanid and ampharetid polychaetes one animal ... -
Gammarid amphipods (Crustacea) in Norway, with a key to the species
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-28)Thirteen species in the amphipod family Gammaridae have been reported from Norway. This paper gives a survey of the distribution and habitat of all 13 species of the family Gammaridae occurring or expected to occur in Norwegian waters: both marine, brackish and fresh, including Svalbard, in addition to four species found in close neighbouring waters. It also provides a short history of the study of ... -
A genetic fingerprint of Amphipoda from Icelandic waters – the baseline for further biodiversity and biogeography studies
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-23)Amphipods constitute an abundant part of Icelandic deep-sea zoobenthos yet knowledge of the diversity of this fauna, particularly at the molecular level, is scarce. The present work aims to use molecular methods to investigate genetic variation of the Amphipoda sampled during two IceAGE collecting expeditions. The mitochondrial cytochrome oxidase subunit 1 (COI) of 167 individuals originally assigned ... -
New and little known species of Lepechinella (Crustacea, Amphipoda, Lepechinellidae) and an allied new genus Lepesubchela from the North Atlantic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-29)New species of Lepechinella, L. norvegica sp. nov. and L. victoriae sp. nov., from the North East Atlantic are described together with the new, closely related genus and species Lepesubchela christinae gen. et sp. nov. Lepechinella arctica Schellenberg, 1926 from north of Spitsbergen and Lepechinella schellenbergi Stephensen, 1944 from Greenland are redescribed. A key to the species of Atlantic ... -
A New Stenothoid (Crustacea: Amphipoda: Stenothoidae) from a Shallow Water Hydroid Polyp in British Columbia, Canada
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023)A new stenothoid species is described from a hydroid polyp in British Columbia, Canada. The new species is provisionally assigned to Metopa as M. insolita sp. nov., pending revision of this genus. -
On a new species of Amphilochus from deep and cold Atlanic waters, with a note on the genus Amphilochopsis (Amphipoda, Gammaridea, Amphilochidae)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-23)<i>Amphilochus manudens</i> and <i>Amphilochopsis hamatus</i> are redescribed based on specimens from the BioIce, Mareano, and IceAGE programmes. Te new species <i>Amphilochus anoculus</i> <b>sp. n.</b> is described based on material from the IceAGE programme and the preceding BioIce programme; it is separated from the closely related <i>Amphilochus manudens</i> by the absence of eyes, a ... -
Onisimus turgidus (Sars, 1879) (Amphipoda, Uristidae), an overlooked amphipod from sea anemones in Northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-18)Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine <i>Onisimus normani</i> Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian material belongs to <i>O. turgidus</i> (Sars, 1879), described from the Barents Sea and for a long time forgotten. This paper fully illustrates both species, gives a key, ... -
Paradulichia spinifera gurjanova, 1946 (Amphipoda, dulichiidae), a valid species?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-11)Examination of Paradulichia-material collected from the Barents Sea during the Mareano cruises indicated that there are clear morphological differences between Paradulichia typica Boeck, 1871 from the Hardangerfjord, W. Norway and Paradulichia spinifera Gurjanova, 1946 from the Arctic. Based on our material and the original descriptions, these differences are the acute ventral parts of the body ... -
The World Amphipoda Database: History and Progress
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-06)We provide an overview of the World Amphipoda Database (WAD), a global speciesdatabase that is part of the World Register of Marine Species (WoRMS). Launched in 2013, the databasecontains entries for over 10,500 accepted species names. Edited currently by 31 amphipod taxonomists,following WoRMS priorities, the WAD has at least one editor per major group. All accepted speciesare checked by the editors, ...
