    • Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels 

      Schultze, Sabrina; Andersen, Tom; Knudtzon, Nina Cathrine; Ruus, Anders; Rundberget, Jan Thomas; Brooks, Steven; Poste, Amanda Elizabeth; Hessen, Dag Olav; Borgå, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-25)
      The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. To compare terrDOM to marine DOM (marDOM) as contaminant vectors to coastal biota, we exposed blue mussels (Mytilus sp.) to the different DOM types in combination with ...

    • Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton 

      Carrasco, Nathalie; Mcgovern, Maeve; Evenset, Anita; Søreide, Janne E.; Arts, Michael T.; Jonsson, Sofi; Poste, Amanda Elizabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)
      Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing Hg exposure of marine food webs. The main aim of this study was to determine the impacts of seasonal riverine inputs on land-ocean Hg transport, zooplankton diet and Hg bioaccumulation ...

    • 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 ...
