• Complex relationships between marine growth and age at maturity in Atlantic salmon 

  Burton, Tim; Bolstad, Geir Hysing; Fiske, Peder; Østborg, Gunnel Marie; Løkeberg, Gitte Line; Thorstad, Eva Bonsak (Peer reviewed, 2025)

  Drastic declines in abundance of Atlantic salmon have been attributed to ecosystem change at sea reducing growth in body size, which in turn could impact survival because mortality at sea may be size-selective. A less ...

• Assessing the extraordinary measures used to counteract invasion of pink salmon into the North Atlantic 

  Thorstad, Eva Bonsak; Frøiland, Eirik; Fagard, Pierre; Kvaal, Marianne Lucie Legouy; Lehne, Camilla Kvitberg; Liberg, Egil; Sandodden, Roar; Skaala, Øystein (Peer reviewed, 2025)

  Pink salmon is an invasive fish species to the North Atlantic Ocean and Barents Sea regions, spreading from intentional releases in north-west Russia. We assess the removal methods used in 94 Norwegian rivers in 2023. In ...

M.; Vray, Sarah; Haase, Peter (Peer reviewed; Journal article, 2024)

  Humans impact terrestrial, marine and freshwater ecosystems, yet many broad-scale studies have found no systematic, negative biodiversity changes (for example, decreasing abundance or taxon richness). Here we show that ...

• Ice-inhabiting species of Bdelloidea Rotifera reveal a pre-Quaternary ancestry in the Arctic cryosphere 

  Shain, Daniel H.; Rogozhina, Irina; Fontaneto, Diego; Nesje, Atle; Saglam, Naim; Bartlett, Jesamine; Zawierucha, Krzysztof; Kielland, Øystein Nordeide; Dunshea, Glenn John; Arnason, Einar; Rosvold, Jørgen (Peer reviewed; Journal article, 2024)

  Historical climate data indicate that the Earth has passed through multiple geological periods with much warmer-than-present climates, including epochs of the Miocene (23–5.3 mya BP) with temperatures 3–4°C above present, ...
