    • Increasing temperatures, diversity loss and reorganization of deep-sea fish communities east of Greenland 

      Emblemsvåg, Margrete; Núñez-Riboni, Ismael; Christensen, Helle Torp; Nogueira, Adriana; Gundersen, Agnes Christine; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      In recent years, Arctic and sub-Arctic fish communities have shown extensive reorganization on shelves and in shallow waters, but little is known about the ecological impact of environmental changes in deeper waters. We examined temporal changes (1998-2016) in fish diversity and community structure based on research survey data from East Greenland, over a depth gradient spanning 400 to 1500 m. A ...

    • Migration patterns of Greenland halibut in the North Atlantic revealed by a compiled mark-recapture dataset 

      Vihtakari, Mikko; Elvarsson, Bjarki Pór; Treble, Margaret; Nogueira, Adriana; Hedges, Kevin; Hussey, Nigel E.; Wheeland, Laura; Roy, Denis; Ofstad, Lise Helen; Hallfredsson, Elvar Halldor; Barkley, Amanda; Estevez-Barcia, Daniel; Nygaard, Rasmus; Healey, Brian; Steingrund, Petur; Johansen, Torild; Albert, Ole Thomas; Boje, Jesper (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-18)
      Marine fisheries are often allocated to stocks that reflect pragmatic considerations and may not represent the species’ spatial population structure, increasing the risk of mismanagement and unsustainable harvesting. Here we compile mark–recapture data collected across the North Atlantic to gain insight into the spatial population structure of Greenland halibut (Reinhardtius hippoglossoides), an ...

    • Pan-Arctic suitable habitat model for Greenland halibut 

      Vihtakari, Mikko; Hordoir, Robinson; Treble, Margret A; Bryan, Meaghan D.; Elvarsson, Bjarki; Nogueira, Adriana; Hallfredsson, Elvar H.; Christiansen, Jørgen Schou; Albert, Ole Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-08)
      Deep-sea marine fishes support important fisheries but estimates of their distributions are often incomplete as the data behind them may reflect fishing practices, access rights, or political boundaries, rather than actual geographic distributions. We use a simple suitable habitat model based on bottom depth, temperature, and salinity to estimate the potential distribution of Greenland halibut ...

    • Recent warming causes functional borealization and diversity loss in deep fish communities east of Greenland 

      Emblemsvåg, Margrete; Pecuchet, Laurene; Velle, Liv Guri; Nogueira, Adriana; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-13)
      Aim: We assessed temporal trends in functional diversity of the deep-sea demersal fish communities of East Greenland to characterize ecological responses to rising sea temperatures.<p> <p>Location: The study region encompasses a shelf and slope area located offshore between 63°N and 66°N, east of Greenland. <p>Methods: A unique dataset of demersal fish abundance covering a depth range of 1500 m ...
