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 ...

-
(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, 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, 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 / 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 / AcceptedVersion; Peer reviewed, 2017)Orchids are one of the largest plant families and are commercially traded for a variety of purposes, including as ornamental plants, medicinal products and food. These markets involve thousands of species, which may be ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The Norwegian river Suldalslågen, known for its population of large‐sized Atlantic salmon (Salmo salar ), has been regulated for hydropower in 1966–1967 and in 1980. The initial regulation increased winter flows and reduced ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)This paper provides a theoretical understanding of sampling bias in presence-only data in the context of species distribution modelling. This understanding forms the basis for two integrated frameworks, one for detecting ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Analysis of microbial community structure by multivariate ordination methods, using data obtained by high‐throughput sequencing of amplified markers (i.e., DNA metabarcoding), often requires clustering of DNA sequences ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Previous studies based on single mitochondrial markers have shown that the common raven (Corvus corax) consists of two highly diverged lineages that are hypothesised to have undergone speciation reversal upon secondary ...
-
(Doctoral thesis / Doktoravhandling, 2009)Large herbivores such as sheep affect plants directly and indirectly through selective foraging, trampling, urination and defecation, thereby modifying intra- and interspecific interactions and altering resource availability ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Positive selection acting on Toll‐like receptors (TLRs) has been recently investigated to reveal evolutionary mechanisms of host–pathogen molecular co‐adaptation. Much of this research, however, has focused mainly on the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)House sparrows (Passer domesticus) are a hugely successful anthrodependent species; occurring on nearly every continent. Yet, despite their ubiquity and familiarity to humans, surprisingly little is known about their ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Only one species of the genus Allodia has been previously recorded from the Afrotropical region, Allodia (Brachycampta) flavorufa Matile, 1978. Six new species are described here, all representing the nominotypical subgenus, ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)Intraspecific competition for food is expected to increase the trophic niche width of consumers, defined here as their diet diversity, but this process has been little studied in herbivores. Population densities of small ...
