    • Can root-associated fungi mediate the impact of abiotic conditions on the growth of a High Arctic herb? 

      Wutkowska, Magdalena; Ehrich, Dorothee; Mundra, Sunil; Vader, Anna; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-04)
      Arctic plants are affected by many stressors. Root-associated fungi are thought to influence plant performance in stressful environmental conditions. However, the relationships are not well-known; do the number of fungal partners, their ecological functions and community composition mediate the impact of environmental conditions and/or influence host plant performance? To address these questions, ...

    • Seasonality in land–ocean connectivity and local processes control sediment bacterial community structure and function in a High Arctic tidal flat 

      Handler, Eleanor R.; Andersen, Sebastian; Gradinger, Rolf Rudolf; Mcgovern, Maeve; Vader, Anna; Poste, Amanda Elizabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-18)
      Climate change is altering patterns of precipitation, cryosphere thaw, and land–ocean influxes, affecting understudied Arctic estuarine tidal flats. These transitional zones between terrestrial and marine systems are hotspots for biogeochemical cycling, often driven by microbial processes. We investigated surface sediment bacterial community composition and function from May to September along a ...

    • Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic 

      Skogseth, Ragnheid; Olivier, Léa L.A.; Nilsen, Frank; Falck, Eva; Fraser, Neil J.; Tverberg, Vigdis; Ledang, Anna Birgitta; Vader, Anna; Jonassen, Marius Opsanger; Søreide, Janne; Cottier, Finlo Robert; Berge, Jørgen; Ivanov, Boris V.; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of Svalbard. Variability and trends in this fjord’s climate and circulation are therefore analysed from observational and reanalysis data during 1987 to 2017. Isfjorden experienced a ...
