Changes in greening in the High Arctic - insights from a 30-year AVHRR max NDVI dataset for Svalbard
(Journal article; Peer reviewed, 2016)Satellite-aided studies of vegetation cover, biomass and productivity are becoming increasingly important formonitoring the effects of a changing climate on the biosphere. With their large spatial coverage and good temporal ... -
Changes in growing season duration and productivity of northern vegetation inferred from long-term remote sensing data
(Journal article; Peer reviewed, 2016)Monitoring and understanding climate-induced changes in the boreal and arctic vegetation is critical to aid in prognosticating their future.Weused a 33 year (1982–2014) long record of satellite observations to robustly ... -
Changes in timing of seasonal peak photosynthetic activity in northern ecosystems
(Journal article; Peer reviewed, 2019)Seasonality in photosynthetic activity is a critical component of seasonal carbon, water and energy cycles in the Earth system. This characteristic is a consequence of plant’s adaptive evolutionary processes to a given set ... -
Changes in trophic state and aquatic communities in high Arctic ponds in response to increasing goose populations
(Peer reviewed; Journal article, 2019)1. The high Arctic, including the Svalbard archipelago in the North Atlantic, has been exposed to direct and indirect drivers of climatic change such as rising temperatures and associated changes in hydrology and nutrient ... -
Changes in wetland habitat use by waterbirds wintering in Czechia are related to diet and distribution changes
(Peer reviewed; Journal article, 2021)1. Understanding species habitat use and factors affecting changes in their distribu-tions are necessary to promote the conservation of any biological community. We evaluated the changes in wetland use of the non- breeding ... -
Changes in winter warming events in the Nordic Arctic Region
(Journal article; Peer reviewed, 2016)In recent years extreme winter warming events have been reported in arctic areas. These events are characterized as extraordinarily warm weather episodes, occasionally combined with intense rainfall, causing ecological ... -
Changing Arctic snow cover: A review of recent developments and assessment of future needs for observations, modelling, and impacts
(Journal article, 2016)Snow is a critically important and rapidly changing feature of the Arctic. However, snow-cover and snowpack conditions change through time pose challenges for measuring and prediction of snow. Plausible scenarios of ... -
Changing contributions of stochastic and deterministic processes in community assembly over a successional gradient
(Journal article; Peer reviewed, 2017)Successional dynamics in plant community assembly may result from both deterministic and stochastic ecological processes. The relative importance of different ecological processes is expected to vary over the successional ... -
Characterisation and mapping of landscape types, a case study from Norway
(Journal article; Peer reviewed, 2016)The European Landscape Convention emphasises the human perception of landscapes in its definition of the landscape, and promotes citizen participation in landscape management processes. On the other hand, landscape ... -
Characteristics of temporal changes in communities where dynamics differ between species
(Peer reviewed; Journal article, 2016)Communities with different phenotypic variation among species can have identical species abundance distributions, although their temporal dynamics may be very different. By using stochastic species abundance models, both ... -
Characteristics, drivers and feedbacks of global greening

Chasing the bird: 3D acoustic tracking of aerial flight displays with a minimal planar microphone array
(Peer reviewed; Journal article, 2023)Tracking the flight patterns of birds and bats in three-dimensional space is central to key questions in evolutionary ecology but remains a difficult technical challenge. For example, complex aerial flight displays are ... -
Chewing lice Trichodectes pinguis pinguis in Scandinavian brown bears (Ursus arctos)
(Journal article; Peer reviewed, 2016)In April 2014 and 2015, we noted localized alopecia (neck, forelimbs, and chest) and hyperpigmentation on two adult brown bears (Ursus arctos) captured in central-south Sweden for ecological studies under the Scandinavian ... -
Children and nearby nature: A nationwide parental survey from Norway
(Peer reviewed; Journal article, 2016)tThe aim of this paper is to describe the availability of and use of nearby outdoor spaces along a naturecontinuum by Norwegian children. We carried out a nationwide survey of 3 160 parents with childrenaged 6–12 years, ... -
China and India lead in greening of the world through land-use management
(Journal article; Peer reviewed, 2019)Satellite data show increasing leaf area of vegetation due to direct factors (human land-use management) and indirect factors (such as climate change, CO2 fertilization, nitrogen deposition and recovery from natural ... -
Circadian rhythmicity persists through the Polar night and midnight sun in Svalbard reindeer
(Journal article; Peer reviewed, 2018)Studies of locomotor activity in Svalbard reindeer reported the temporary absence of diel rhythms under Arctic photic conditions. However, using Lomb-Scargle periodogram analyses with high statistical power we found diel ... -
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, ... -
Circumpolar dynamics of a marine top-predator track ocean warming rates.
(Journal article; Peer reviewed, 2017)Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of ... -
A circumpolar study unveils a positive non-linear effect oftemperature on arctic arthropod availability that may reduce therisk of warming-induced trophic mismatch for breeding shorebirds
(Peer reviewed; Journal article, 2024)Seasonally abundant arthropods are a crucial food source for many migratorybirds that breed in the Arctic. In cold environments, the growth and emergence ofarthropods are particularly tied to temperature. Thus, the phenology ... -
Citationchaser: A tool for transparent and efficient forward and backward citation chasing in systematic searching
(Peer reviewed; Journal article, 2022)Systematic searching aims to find all possibly relevant research from multiple sources, the basis for an unbiased and comprehensive evidence base. Along with bibliographic databases, systematic reviewers use a variety of ...
