Selective feeding on jellyfish organs by northern fulmars Fulmarus glacialis
(Peer reviewed; Journal article, 2019)Several marine animals prey extensively on jellyfish in spite of the low energy contents of this type of prey. Northern Fulmars Fulmarus glacialis observed in the Barents Sea feeding on medusae of lion’s mane jellies Cyanea ... -
Setting the baseline for the dynamics of siphonophores and hydromedusae in Oslofjorden
(Journal article; Peer reviewed, 2022)Knowledge of the spatio-temporal dynamics of hydromedusae and siphonophores is scarce despite their key role as predators. In the temperate inlet of Oslofjorden, studies dealing with these organisms are limited to a few ... -
Shrimps of the genus Periclimenes (Crustacea, Decapoda, Palaemonidae) associated with mushroom corals (Scleractinia, Fungiidae): Linking DNA barcodes to morphology
(Journal article; Peer reviewed, 2019)Most marine palaemonid shrimp species live in symbiosis with invertebrates of various phyla. These associations range from weak epibiosis to obligatory endosymbiosis and from restricted commensalism to semi-parasitism. On ... -
Size variation in mid-Holocene North Atlantic Puffins indicates a dynamic response to climate change
(Journal article; Peer reviewed, 2021-02-24)Seabirds are one of the most at-risk groups, with many species in decline. In Scandinavia, seabirds are at a heightened risk of extinction due to accelerated global warming. Norway is home to significant portion of the ... -
Skipping-type migration in a small Arctic wader, the Temminck's stint Calidris temminckii
(Peer reviewed; Journal article, 2015-03)By using morphometric data and geolocator tracking we investigated fuel loads and spatio-temporal patterns of migration and non-breeding in Temminck's stints Calidris temminckii. Body masses in stints captured at autumn ... -
The smallest known species of Afrotropical Scolytoplatypus Schaufuss (Curculionidae, Scolytinae) - with unique features and an isolated phylogenetic position
(Peer reviewed; Journal article, 2018-04-10)Recent flight intercept trapping in Gabon provided four female specimens of a new species of Scolytoplatypus Schaufuss with several unusual features. It is the smallest known Afrotropical species found to date (1.6 mm ... -
Speciation in the dark: Diversification and biogeography of the deep-sea gastropod genus Scaphander in the Atlantic Ocean
(Peer reviewed; Journal article, 2015-01-30)Aim The aim of this work was to improve understanding about the mode, geography and tempo of diversification in deep-sea organisms, using a time-calibrated molecular phylogeny of the heterobranch gastropod genus Scaphander. ... -
Species delimitation analyses of NE Atlantic Chaetozone (Annelida, Cirratulidae) reveals hidden diversity among a common and abundant marine annelid
(Journal article; Peer reviewed, 2020)The polychaetes of the family Cirratulidae (Annelida) are common inhabitants in continental shelf benthic environments and considered an important group of organisms in environmental monitoring surveys. The family represents ... -
Stable Isotope Analysis of Specimens of Opportunity Reveals Ocean-Scale Site Fidelity in an Elusive Whale Species
(Journal article; Peer reviewed, 2021)Elusive wildlife are challenging to study, manage, or conserve, as the difficulty of obtaining specimens or conducting direct observations leads to major data deficiencies. Specimens of opportunity, such as salvaged carcasses ... -
Stable Isotope Evidence for Late Medieval (14th–15th C) Origins of the Eastern Baltic Cod (Gadus morhua) Fishery
(Peer reviewed; Journal article, 2011-11-16)Although recent historical ecology studies have extended quantitative knowledge of eastern Baltic cod (Gadus morhua) exploitation back as far as the 16th century, the historical origin of the modern fishery remains obscure. ... -
Successful application of ancient DNA extraction and library construction protocols to museum wet collection specimens
(Journal article; Peer reviewed, 2021)Millions of scientific specimens are housed in museum collections, a large part of which are fluid preserved. The use of formaldehyde as fixative and subsequent storage in ethanol is especially common in ichthyology and ... -
