Stand structure, recruitment and growth dynamics in mixed subalpine spruce and Swiss stone pine forests in the Eastern Carpathians
(Journal article; Peer reviewed, 2017)Natural subalpine forests are considered to be sensitive to climate change, and forest characteristics are assumed to reflect the prevalent disturbance regime. We hypothesize that stand history determines different stand ... -
State and transition model approach in native forests of Southern Patagonia (Argentina): linking ecosystem services, thresholds and resilience
(Journal article; Peer reviewed, 2017)The sustainable use of ñire forests requires knowledge of its dynamics and management to maintain long-term main forest ecosystem services. The aim of this work was to develop a structural–functional state and transition ... -
Statistical and ecological challenges of monitoring parasitic salmon lice infestations in wild salmonid fish stocks
(Peer reviewed; Journal article, 2015)Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling. Parasite infestations are ... -
Status and trends in Arctic vegetation: Evidence from experimental warming and long-term monitoring
(Journal article; Peer reviewed, 2019)Changes in Arctic vegetation can have important implications for trophic interactions and ecosystem functioning leading to climate feedbacks. Plot-based vegetation surveys provide detailed insight into vegetation changes ... -
Stedsnavn i Tirol: endonymiprinsippets utfordringer i møtet med språklig og toponymisk mangfold
(Peer reviewed; Journal article, 2023)Toponyms of Tyrol – how to apply the endonymic principle in a highly diverse namescape -
Steep declines in radioactive caesium after 30 years of monitoring alpine plants in mountain areas of central Norway
(Peer reviewed; Journal article, 2023)The Chernobyl accident exposed large areas of northern Europe to radiocaesium (137Cs). We investigated temporal and spatial variation in concentrations of radiocaesium among five functional groups of alpine plants at two ... -
Strandenger i Østfold – areal, økologisk tilstand og rødlistearter
(Journal article; Peer reviewed, 2014)Salt meadows in Østfold – area, ecological condition and red listed species -
Strategic conservation for lesser prairie-chickens among landscapes of varying anthropogenic influence
(Journal article, 2019)For millennia grasslands have provided a myriad of ecosystem services and have been coupled with human resource use. The loss of 46% of grasslands worldwide necessitates the need for conservation that is spatially, temporally, ... -
A stream-to-sea experiment reveals inhibitory effects of freshwater residency on organic-matter decomposition in the sea
(Peer reviewed; Journal article, 2022)One billion tons of carbon are annually transported to the global ocean, and the fate of this carbon hinges notonly on marine processing rates, but also on freshwater processing during downstream transport. Using acotton-strip ... -
Stress-induced secondary leaves of a boreal deciduous shrub (Vaccinium myrtillus) overwinter then regain activity the following growing season
(Journal article; Peer reviewed, 2018)The ericoid shrub Vaccinium myrtillus is one of several deciduous boreal plants that respond to larval defoliation by compensatory production of a new set of leaves within the same growing season soon after defoliation. ... -
The structural variation landscape in 492 Atlantic salmon genomes
(Peer reviewed; Journal article, 2020)Structural variants (SVs) are a major source of genetic and phenotypic variation, but remain challenging to accurately type and are hence poorly characterized in most species. We present an approach for reliable SV discovery ... -
Stylonectria norvegica (Nectriaceae), a new species fromNorway
(Peer reviewed; Journal article, 2015)Stylonectria norvegica sp. nov. is described from three collections on pyrenomycetous hosts on Quercus, Betula and Alnus in Norway. The fusarium-like asexual state was obtained in culture and the ITS1- 5.8S-ITS2 loci ... -
Sub-arctic mosses and lichens show idiosyncratic responses to combinations of winter heatwaves, freezing and nitrogen deposition
(Peer reviewed; Journal article, 2023)Arctic ecosystems are increasingly exposed to extreme climatic events throughout the year, which can affect species performance. Cryptogams (bryophytes and lichens) provide important ecosystem services in polar ecosystems ... -
Supplementary stocking selects for domesticated genotypes
(Journal article; Peer reviewed, 2019)Stocking of hatchery produced fish is common practise to mitigate declines in natural populations and may have unwanted genetic consequences. Here we describe a novel phenomenon arising where broodstock used for stocking ... -
Supportive breeders of Atlantic salmon Salmo salar have reduced fitness in nature
(Peer reviewed; Journal article, 2019)Wild Atlantic salmon (Salmo salar) are in decline over the entire distribution area, and populations are enhanced by supportive breeding. Parental fish are sampled in rivers, crossed and the offspring reared in hatcheries ... -
Survival and cause-specific mortality of harvested willow ptarmigan (Lagopus lagopus) in central Norway
(Peer reviewed; Journal article, 2020)Survival is a key demographic component that often varies as a result of human activities such as recreational harvest. Detailed understanding of seasonal variation in mortality patterns and the role of various risk factors ... -
Survival and Migration of Rock Ptarmigan in Central Scandinavia
(Peer reviewed; Journal article, 2020)In a world undergoing massive declines in the distribution and abundance of many wildlife species, documenting basic ecological characteristics is often needed to be able to understand and potentially mitigate current and ... -
Survival estimates strongly depend on capture–recapture designs in a disturbed environment inducing dispersal
(Journal article; Peer reviewed, 2018)Capture-Recapture (CR) approaches are extensively used to estimate demographic parameters. Their robustness relies on the selection of suitable statistical models, but also on the sampling design and effort deployed in the ... -
Survival rate and breeding outputs in a high Arctic seabird exposed to legacy persistent organic pollutants and mercury
(Journal article; Peer reviewed, 2015)Chronic exposure to pollutants may represent a threat for wildlife.We tested whether adult survival rate, breeding probability and breeding success the year of sampling and the following year were affected by blood levels ... -
Surviving the antarctic winter—life stage cold tolerance and ice entrapment survival in the invasive chironomid midge Eretmoptera murphyi
(Peer reviewed; Journal article, 2020)An insect’s ability to tolerate winter conditions is a critical determinant of its success. This is true for both native and invasive species, and especially so in harsh polar environments. The midge Eretmoptera murphyi ...
