Salmonid fishes in a changing climate : the winter challenge
Finstad, Anders Gravbrøt (Doktoravhandlinger ved NTNU, 1503-8181; 2005:199, Doctoral thesis, 2005)In the present thesis, winter mortality was linked to levels of stored energy by a field study from a northern Atlantic salmon population where population frequency distributions for specific somatic energy were compared ... -
Spatial distribution of biodiversity citizen science in a natural area depends on area accessibility and differs from other recreational area use
Mandeville, Caitlin P.; Nilsen, Erlend Birkeland; Finstad, Anders Gravbrøt (Peer reviewed; Journal article, 2022)Opportunistic citizen science produces large amounts of primary biodiversity data but is underutilized in the conservation and management of protected areas despite these areas’ status as citizen science hotspots.

Testing variation in recruitment of dwarfs and cannibals in populations of Arctic char (Salvelinus alpinus) at Bear Island
Hornnæs, Tonje (Master thesis, 2020)Sammendrag 1. Røye (Salvelinus alpinus) er den ferskvannsfisken med nordligst utbredelse, og er ofte den eneste fiskearten til stede i mange subarktiske og arktiske innsjøer. Røyepopulasjoner i disse områdene, og spesielt ... -
When soft waters becomes softer; drivers of critically low levels of Ca in Norwegian lakes
Hessen, Dag Olav; Andersen, Tom; Tominaga, Koji; Finstad, Anders Gravbrøt (Journal article; Peer reviewed, 2017)In this study, we analyzed long-term trends in calcium (Ca) concentrations for 70 Norwegian lakes spanning a broad geographical range and for a wide range of ambient drivers. A striking decline in Ca concentrations was ... -
Ørekyt i Namsenvassdraget. Utbredelse, spredningsrisiko og tiltak
Thorstad, Eva Bonsak; Sandlund, Odd Terje; Heggberget, Tor Gravråk; Finstad, Anders Gravbrøt; Museth, Jon; Berger, Hans Mack; Hesthagen, Trygve H.; Berg, Ole Kristian (NINA rapport;155, Research report, 2006)Undersøkelser i Namsenvassdraget i 2005 viste at ørekyt forekommer i tette bestander i innsjøer og flyer øverst i vassdraget. I Otersjøen øverst i Sanddøla har ørekyt forekommet i solide bestander siden 1960-tallet. I ...
