Back from the Past: DNA Barcodes and Morphology Support Ablabesmyia americana Fittkau as a Valid Species (Diptera: Chironomidae)
(Journal article; Peer reviewed, 2019)Abstract: Short, standardized gene fragments for species identification (DNA barcodes) have proven effective in delineating closely-related insect species, and can be critical characters to include in taxonomic studies. ... -
Background invertebrate herbivory on dwarf birch (Betula glandulosa-nana complex) increases with temperature and precipitation across the tundra biome
(Journal article; Peer reviewed, 2017)Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The magnitude of these changes is however hard to ... -
BAGS: An automated Barcode, Audit & Grade System for DNA barcode reference libraries
(Peer reviewed; Journal article, 2020)Biodiversity studies greatly benefit from molecular tools, such as DNA metabarcoding, which provides an effective identification tool in biomonitoring and conservation programmes. The accuracy of species‐level assignment, ... -

Benthic Communities on the Mohn’s Treasure Mound: Implications for Management of Seabed Mining in the Arctic Mid-Ocean Ridge
(Peer reviewed; Journal article, 2020)The Mohn’s Treasure, described as an inactive sulfide mound, was discovered at 2,600- m depth on the Arctic Mid-Ocean Ridge (AMOR) in 2002. In 2015, we conducted the first biological survey of Mohn’s Treasure using remotely ... -

Beskrivelser av torvmassivenheter. Kunnskapsgrunnlag for NiN 3.0
(NTNU Vitenskapsmuseet naturhistorisk rapport;, Research report, 2023)Norwegian Summary Myr defineres som et landområde med vegetasjon som krever fuktighet, og som danner torv. Torv er sted-egent akkumulert materiale, hvis tørrvekt utgjøres av mer enn 30 % dødt organisk materiale. Det er ... -
Bestandsovervåking og skjøtselsplan for mnemosynesommerfugl Parnassius mnemosyne
(NINA rapport;676, Research report, 2011)Mnemosynesommerfugl (Parnassius mnemosyne) er i Norge kun kjent fra sørvendte rasmarker på Vestlandet fra Sunndalen i Møre og Romsdal til Gudvangen i Sogn og Fjordane. Artens forekomst i Norge er fordelt på flere atskilte ... -

Beyond DNA barcoding: The unrealized potential of genome skim data in sample identification
(Peer reviewed; Journal article, 2020)Genetic tools are increasingly used to identify and discriminate between species. One key transition in this process was the recognition of the potential of the ca 658bp fragment of the organelle cytochrome c oxidase I ... -
Beyond ecological opportunity: prey diversity rather than abundance shapes predator niche variation
(Peer reviewed; Journal article, 2021)Ecological opportunity (i.e. the diversity of available resources) has a pivotal role in shaping niche variation and trophic specialisation of animals. However, ecological opportunity can be described with regard to both ... -
Biding time before breeding: flexible use of the Arctic landscape by migratory geese during spring
(Journal article; Peer reviewed, 2015)Many millions of long-distance migrants use pre-breeding staging sites located adjacent to breeding grounds immediately prior to nesting, presumably to improve body condition and thus reproductive success. However, in ... -
Biodiversitet i plantefelt med gran (Picea abies) og i plantefelt med sitkagran (P. sitchensis). En sammenlignende studie.
(NINA Rapport;1031, Research report, 2014)Kunnskapen om biodiversitet i plantefelt av introduserte bartre er generelt mangelfull. Hovedmålet med dette prosjektet har vært å få større kunnskap om hvilken betydning plantefelt med sitkagran (Picea sitchensis) kan ha ... -
Biodiversity hotspot in cold waters: a review of the genus Cuthonella with descriptions of seven new species (Mollusca, Nudibranchia)
(Peer reviewed; Journal article, 2020)Cuthonella Bergh, 1884 is of one of the most neglected nudibranch groups, with a long history of taxonomic confusion with other aeolidacean genera. Owing to its predominantly Arctic distribution with cold water, its species ... -
Biogeographic patterns of distribution of the mollusc Zelentia ninel (Nudibranchia, Trinchesiidae)
(Peer reviewed; Journal article, 2023)In the present contribution we report, for the first time, records of the nudibranch Zelentia ninel from Norway. The species is previously known only from the Barents Sea coast in northern Russia where it was described for ... -
