(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)To determine the present-day community composition of siliceous Rhizaria (Radiolaria and Phaeodaria) in Norwegian fjords, plankton tows were conducted in south-western and northern Norwegian fjords in September 2016. The ...

Range contraction and increasing isolation of a polar bear subpopulation in an era of sea ice loss (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased ...

Range contraction and increasing isolation of a polar bear subpopulation in an era of sea ice loss. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Background and Aims The Arctic tundra, with its extreme temperatures and short growing season, is evolutionarily young and harbours one of the most species-poor floras on Earth. ...

-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Gene expression changes potentially play an important role in adaptive evolution under human‐induced selection pressures, but this has been challenging to demonstrate in natural populations. Fishing exhibits strong selection ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Investigation of bryozoan faunas collected in two submarine caves in Lesvos Island, Aegean Sea revealed a great number of colonies of three species currently assigned to the cheilostome family Onychocellidae: Onychocella ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background The temporal origin and diversification of orchids (family Orchidaceae) has been subject to intense debate in the last decade. The description of the first reliable fossil in 2007 enabled a direct ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Ethnopharmacological relevance What are the minimum methodological and conceptual requirements for an ethnopharmacological field study? How can the results of ethnopharmacological field studies be reported so that researchers ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Tropical ecosystems are undergoing unprecedented rates of degradation from deforestation, fire, and drought disturbances. The collective effects of these disturbances threaten to shift large portions of tropical ecosystems ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Much adaptive evolutionary change is underlain by mutational variation in regions of the genome that regulate gene expression rather than in the coding regions of the genes themselves. An understanding of the role of gene ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Both molecular and morphologic characters support the reinstatement of Leuctra biellensis Festa, 1942 as a valid species distinct from Leuctra nigra (Olivier, 1811). Genetic distances between L. biellensis and the different ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The number of individuals of species varies, but estimating abundance, given incomplete and biased sampling in both contemporary and fossilized communities, is challenging. Here, we describe a new occupancy ...
-
Reliability in distribution modeling — A synthesis and step-by-step guidelines for improved practice (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Information about the distribution of a study object (e.g., species or habitat) is essential in face of increasing pressure from land or sea use, and climate change. Distribution models are instrumental for acquiring such ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Incomplete documentary evidence, variable biomolecular preservation, and limited skeletal responses have hindered assessment of acute infections in the past. This study was initially developed to explore the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)1. The restriction site-associated DNA (RADseq) family of protocols involves digesting DNA and sequencing the region flanking the cut site, thus providing a cost and time-efficient way for obtaining thousands of genomic ...

Reproductive coordination breeds success: the importance of the partnership in avian sperm biology (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Previous experience with a partner can improve reproductive coordination between a pair and increase offspring production. We paired inexperienced zebra finches and investigated how a pairs’ experience and their reproductive ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion; Peer reviewed, 2018)Male fertilization success depends on investment in both pre- and postcopulatory sexually selected traits, and considerable attention has recently been paid to quantifying the strength and direction of covariance between ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The late Paleozoic was characterized by a series of continental collisions and ice ages. Despite the drastic environmental changes, sparse sulfur isotope data hinder our understanding of the late Paleozoic biogeochemical ...
