(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Among vertebrates, amphibians currently have the highest proportion of threatened species worldwide, mainly through loss of habitat, leading to increased population isolation. Smaller amphibian populations may lose more ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Partial migration is common among northern ungulates, typically involving an altitudinal movement for seasonally migratory individuals. The main driving force behind migration is the benefit of an extended period of access ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Many species around the world have collapsed, yet only some have recovered. A key question is what happens to populations post collapse. Traditionally, marine fish collapses are linked to overfishing, poor climate, and ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Recent studies suggest that previous estimates of mesopelagic biomasses are severely biased, with the new, higher estimates underlining the need to unveil behaviourally mediated coupling between shallow and deep ocean ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Balancing selection, an evolutionary force that retains genetic diversity, has been detected in multiple genes and organisms, such as the sexual mating loci in fungi. However, to quantify the strength of balancing selection ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Over the last decades the phylogeography and genetic structure of a multitude of species inhabiting Europe and North America have been described. The flora and fauna of the vast landmasses of north-eastern Eurasia are still ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Workflows capable of determining glycopeptides in large-scale are missing in the field of glycoproteomics. We present an approach for automated annotation of intact glycopeptide mass spectra. The steps in adopting the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Large-scale finfish farms are increasingly located in dispersive hard-bottom environments where Laminaria hyperborea forests dominate; however, the interactions between farm effluents and kelp forests are poorly understood. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Abyssal plains are among the most biodiverse yet least explored marine ecosystems on our planet, and they are increasingly threatened by human impacts, including future deep seafloor mining. Recovery of abyssal populations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)1. Hunting and culling are frequently used to combat infectious wildlife diseases. The aim is to markedly lower population density in order to limit disease transmission or to eradicate the host. Massive host culling can ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In the threespine stickleback Gasterosteus aculeatus model system, phenotypes are often classified into three morphs according to lateral plate number. Morph identity has been shown to be largely genetically determined, ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The reproductive success of marine ectotherms is especially vulnerable in warming oceans due to alterations in adult physiology, as well as embryonic and larval survival prospects. These vital responses may, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)1. Distinguishing correlative and causal connections among time series is an important challenge in evolutionary biology, ecology, macroevolution and palaeobiology. 2. Here, we present layeranalyzer, an r package that ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Enterocin K1 (EntK1), enterocin EJ97 (EntEJ97), and LsbB are three sequence related leaderless bacteriocins. Yet LsbB kills only lactococci while EntK1 and EntEJ97 target wider spectra with EntK1 being particularly active ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The life span of leaves increases with their mass per unit area (LMA). It is unclear why. Here, we show that this empirical generalization (the foundation of the worldwide leaf economics spectrum) is a consequence of natural ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The aims of this paper are three-fold: 1. To analyse the development and stability in vegetative traits such as leaf shape, growth and pigmentation patterns in three different morphotypes (defined by leaf shape and ...

Learning and loving of nature in the Anthropocene. How to broaden science with curiosity and passion (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)What does “belonging to nature” mean today and how can children and young people be inspired to experience this? What basic dilemmas and challenges arise between the requirement for critical thinking on the one side, and ...
