(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Herein, we revise the Rhizocarpon badioatrum species complex in the Nordic countries using molecular phylogenetics combined with morphological/anatomical and chemical data. Bayesian and Maximum Likelihood phylogenetic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The flood pulse of black water rivers in the Amazon basin determines the composition of species along the flood gradient in igapó forests. The Balbina dam, built on the Uatumã River, has altered the flood pulse and caused ...
-
(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, 2023)Background: The phylogenetic bootstrap, first proposed by Felsenstein in 1985, is a critically important statistical method in assessing the robusticity of phylogenetic datasets. Core to its concept was the use of pseudo ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Loss of Arctic sea ice owing to climate change is predicted to reduce both genetic diversity and gene flow in ice-dependent species, with potentially negative consequences for their long-term viability. Here, we tested for ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Current knowledge about Paleolithic human plant use is limited by the rare survival of identifiable plant remains as well as the availability of methods for plant detection and identification. By analyzing DNA preserved ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Mediterranean specimens of the genus Microporella collected from shallow water habitats during several surveys and cruises undertaken mostly off the Italian coast are revised. As a result of the disentanglement of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The two most abundant minerals in the Earth’s lower mantle are bridgmanite and ferropericlase. The bulk modulus of ferropericlase (Fp) softens as iron d-electrons transition from a high-spin to low-spin state, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Sperm cells are exceptionally morphologically diverse across taxa. However, morphology can be quite uniform within species, particularly for species where females copulate with many males per reproductive bout. Strong ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The global expansion of road networks threatens apex predator conservation and ecosystem functioning. This occurs through wildlife-vehicle collisions, habitat loss and fragmentation, reduced genetic connectivity and increased ...
-
(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 / PublishedVersion; Peer reviewed, 2021)Many studies investigating the human microbiome-cancer interface have focused on the gut microbiome and gastrointestinal cancers. Outside of human papillomavirus driving cervical cancer, little is known about the relationship ...
-
(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, 2012)The aim of this study is to examine the effect of individual canopy tree on the species composition and abundance of understorey vegetation in subtropical forests, by applying a model for tree influence on understorey ...
