A mega-cryptic species complex hidden among one of the most common annelids in the North East Atlantic
(Journal article; Peer reviewed, 2018)We investigate mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) genetic structure of North East Atlantic lineages of Terebellides, a genus of sedentary annelids mainly inhabiting continental shelf and slope ... -
Can mowing restore boreal rich-fen vegetation in the face of climate change?
(Journal article; Peer reviewed, 2019)Low-frequency mowing has been proposed to be an effective strategy for the restoration and management of boreal fens after abandonment of traditional haymaking. This study investigates how mowing affects long-term vegetation ... -
Catchment vegetation and temperature mediating trophic interactions and production in plankton communities
(Journal article; Peer reviewed, 2017)Climatic factors influence the interactions among trophic levels in an ecosystem in multiple ways. However, whereas most studies focus on single factors in isolation, mainly due to interrelation and correlation among drivers ... -
Contrasting Patterns of Genetic Structuring in Natural Populations of Arabidopsis lyrata Subsp. petraea across Different Regions in Northern Europe
(Journal article; Peer reviewed, 2014-09-16)Level and partitioning of genetic diversity is expected to vary between contrasting habitats, reflecting differences in strength of ecological and evolutionary processes. Therefore, it is necessary to consider processes ... -
Contrasting spatial, temporal and environmental patterns in observation and specimen based species occurrence data
(Journal article; Peer reviewed, 2018)Species occurrence data records the location and time of an encounter with a species, and is valuable for many aspects of ecological and evolutionary analyses. A key distinction within species occurrence data is between ... -

Cross-Breeding Is Inevitable to Conserve the Highly Inbred Population of Puffin Hunter: The Norwegian Lundehund
(Journal article; Peer reviewed, 2017)The Norwegian Lundehund is a highly endangered native dog breed. Low fertility and high frequency predisposition to intestinal disorder imply inbreeding depression. We assessed the genetic diversity of the Lundehund ... -
Exploring Genetic Divergence in a Species-Rich Insect Genus Using 2790 DNA Barcodes
(Journal article; Peer reviewed, 2015-09-25)DNA barcoding using a fragment of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) has proven to be successful for species-level identification in many animal groups. However, most studies have been focused on ... -
Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding
(Journal article; Peer reviewed, 2015)Sympatric species are expected to minimize competition by partitioning resources, especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime example of a situation where food availability ... -
Long-term changes in northern large-herbivore communities reveal differential rewilding rates in space and time
(Journal article; Peer reviewed, 2019)Herbivores have important impacts on ecological and ecosystem dynamics. Population density and species composition are both important determinants of these impacts. Large herbivore communities are shifting in many parts ... -
Molecular Species Delimitation in the Racomitrium canescens Complex (Grimmiaceae) and Implications for DNA Barcoding of Species Complexes in Mosses
(Journal article; Peer reviewed, 2013)In bryophytes a morphological species concept is still most commonly employed, but delimitation of closely related species based on morphological characters is often difficult. Here we test morphological species circumscriptions ... -
Phylogenetic Evidence of Long Distance Dispersal and Transmission of Piscine Reovirus (PRV) between Farmed and Wild Atlantic Salmon
(Journal article; Peer reviewed, 2013)The extent and effect of disease interaction and pathogen exchange between wild and farmed fish populations is an ongoing debate and an area of research that is difficult to explore. The objective of this study was to ... -
Spatial Genetic Structure of the Abundantand Widespread Peatmoss Sphagnummagellanicum Brid .
(Journal article; Peer reviewed, 2016-02-09)Spore-producing organisms have small dispersal units enabling them to become widespread across continents. However, barriers to gene flow and cryptic speciation may exist. The common, haploid peatmoss Sphagnum magellanicum ... -
The Role of Individual Traits and Environmental Factors for Diet Composition of Sheep
(Peer reviewed; Journal article, 2016)Large herbivore consumption of forage is known to affect vegetation composition and thereby ecosystem functions. It is thus important to understand how diet composition arises as a mixture of individual variation in ...
