DOI: 10.1002/ece3.70809
Abstract: ABSTRACT High‐Arctic environments are facing an elevated pace of warming and increasing human activities, making them more susceptible to the introduction and spread of alien species. We investigated the role of human disturbance in facilitating… read more here.

DOI: 10.1002/ecy.70216
Abstract: Abstract Changing snow conditions due to climate warming may negatively affect the northern fauna that depend on it for their winter survival. To avoid cold temperatures, Arctic lemmings seek refuge in areas with deep snowpack… read more here.

UAV and photogrammetric techniques to study shoreline changes in the high Arctic as exemplified by the Kaffiøyra region, Svalbard
Sign Up to like & getrecommendations! Published in 2025 at "Earth Surface Processes and Landforms"
DOI: 10.1002/esp.70037
Abstract: High‐latitude coasts are among many polar ecosystems vulnerable to global climate change. This paper presents research results on coastline changes in Kaffiøyra, Svalbard (High Arctic). Archival aerial photographs and satellite imagery (1966, 1990, 2017) were… read more here.

Recruitment of benthic invertebrates in high Arctic fjords: Relation to temperature, depth, and season
Sign Up to like & getrecommendations! Published in 2017 at "Limnology and Oceanography"
DOI: 10.1002/lno.10602
Abstract: In the high Arctic, recruitment of hard-bottom benthic organisms has been studied at single locations, but little is known about how it varies spatially or temporally, or how it is influenced by abiotic factors. In… read more here.

Methane cold seeps as biological oases in the high‐Arctic deep sea
Sign Up to like & getrecommendations! Published in 2018 at "Limnology and Oceanography"
DOI: 10.1002/lno.10732
Abstract: Cold seeps can support unique faunal communities via chemosynthetic interactions fueled by seabed emissions of hydrocarbons. Additionally, cold seeps can enhance habitat complexity at the deep seafloor through the accretion of methane derived authigenic carbonates… read more here.

DOI: 10.1002/qj.3877
Abstract: Wintertime warm extremes in the high Arctic, primarily associated with intrusions of moist airmasses from the midlatitudes, have occurred with an ostensibly high frequency in recent years. Here, we compute the temperature anomaly return values… read more here.

DOI: 10.1007/s00248-019-01330-w
Abstract: In the Arctic, climate changes contribute to enhanced mobilization of organic matter in streams. Microbial extracellular enzymes are important mediators of stream organic matter processing, but limited information is available on enzyme processes in this… read more here.

DOI: 10.1007/s00300-024-03235-y
Abstract: Although knowledge of Arctic benthic biodiversity has increased considerably in recent decades, some regions, such as Northeast Greenland, remain poorly studied. The aim of this study was to complement a previous macrofaunal inventory carried out… read more here.
