A calculator for local peatland volume and carbon stock to support area planners and decision makers
(Peer reviewed; Journal article, 2023)Conserving soil carbon is one of many actions to take in limiting global warming. However, carbon dense peatlands are still being drained or excavated. Infrastructure development is one of the major current threats to boral ... -
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 ... -
Can plant traits predict seed dispersal probability via red deer guts, fur, and hooves?
(Journal article; Peer reviewed, 2019)Seed dispersal by mammals provides functional connectivity between isolated plant habitat patches. Across much of Europe, red deer (Cervus elaphus) populations are growing steadily, potentially leading to increasing ... -
Can seasonal fire management reduce the risk of carbon loss from wildfires in a protected Guinea savanna?
(Peer reviewed; Journal article, 2022)Fire is fundamental to the functioning of tropical savannas and routinely used as a management tool. Shifting prescribed burning from later to earlier in the growing season has the potential to reduce greenhouse gas ... -
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 ... -
Cervid Exclusion Alters Boreal Forest Properties with Little Cascading Impacts on Soils
(Journal article; Peer reviewed, 2017)Large herbivores are capable of modifying entire ecosystems with a combination of direct (for example browsing/grazing, trampling, defecation) and indirect (for example affecting plant species composition that then alters ... -
Changes in growth and migration patterns of sea trout before and after the introduction of Atlantic salmon farming
(Peer reviewed; Journal article, 2020)Marine growth has strong implications for reproductive potential and ultimate fitness of sea trout. Hence, the effects of anthropogenic factors on marine growth are important when evaluating population responses and ... -
Changes in the functional diversity of modern bird species over the last million years
(Journal article; Peer reviewed, 2023)Despite evidence of declining biosphere integrity, we currently lack understanding of how the functional diversity associated with changes in abundance among ecological communities has varied over time and before widespread ... -
The Chironomidae (Diptera) of Svalbard and Jan Mayen
(Peer reviewed; Journal article, 2020)Non-biting midges of the fly family Chironomidae are extremely abundant and diverse in Arctic regions and are essential components of Arctic ecosystems. Modern identification tools based on documented records of Arctic ... -
Chironomidae types at the Museum of Comparative Zoology, Boston
(Journal article; Peer reviewed, 2011)The Chironomidae (Insecta: Diptera) type collection deposited at the Museum of Comparative Zoology (MCZ) are listed and reviewed. It is represented by 23 primary types, as well as paratypes and paralectotypes for an ... -
Chironomus rishii sp. n., an enigmatic non-biting midge (Diptera: Chironomidae: Chironominae) from Neotropical region
(Journal article; Peer reviewed, 2018)A new species of Chironomus Meigen, C. rishii (Diptera: Chironomidae: Chironominae) from Brazil, is described and figured as adults male and female, pupa and larva. Adults of C. rishii sp. n. can be recognized by the ... -
Choice of DNA extraction method affects DNA metabarcoding of unsorted invertebrate bulk samples
(Journal article; Peer reviewed, 2018)Characterisation of freshwater benthic biodiversity using DNA metabarcoding may allow more cost-effective environmental assessments than the current morphological-based assessment methods. DNA metabarcoding methods where ... -
Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs
(Peer reviewed; Journal article, 2022)Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, ... -

Climate and land-use drive the functional composition of vascular plant assemblages across Norway
(Peer reviewed; Journal article, 2022)Traditionally, biogeography has described the distribution of species. But as plant functional traits and functional diversity underpin ecosystem dynamics, understanding drivers of functional diversity at biogeographical ... -
Co-diversification of an intestinal Mycoplasma and its salmonid host
(Peer reviewed; Journal article, 2023)Understanding the evolutionary relationships between a host and its intestinal resident bacteria can transform how we understand adaptive phenotypic traits. The interplay between hosts and their resident bacteria inevitably ... -
Coenagrion hastulatum and C. lunulatum – their responses to the liming of acidified lakes and the release of fish
(Journal article; Peer reviewed, 2018)The rare and acidification-tolerant Coenagrion lunulatum became extinct in Romundstadtjern, a small acidic lake in southern Norway, at some time between 1950 and 1980. The reason was suspected to be liming of the lake to ... -
Combined morphological and molecular data unveils relationships of Pseudobranchiomma (Sabellidae, Annelida) and reveals higher diversity of this intriguing group of fan worms in Australia, including potentially introduced species
(Journal article; Peer reviewed, 2016)Pseudobranchiomma (Sabellidae, Annelida) is a small and heterogeneous group of fan worms found in shallow marine environments and is generally associated with hard substrates. The delineation and composition of this genus ... -
Combining population genomics and ecological niche modeling to assess taxon limits between Carex jemtlandica and C. lepidocarpa
(Journal article; Peer reviewed, 2021)Carex section Ceratocystis (Cyperaceae) is a group of recently evolved plant species, in which hybridization is frequent, introgression is documented, taxonomy is complex, and morphological boundaries are vague. Within ... -
Community structure affects trophic ontogeny in a predatory fish
(Journal article; Peer reviewed, 2017)While most studies have focused on the timing and nature of ontogenetic niche shifts, information is scarce about the effects of community structure on trophic ontogeny of top predators. We investigated how community ...
