Climate-driven biophysical changes in feeding and breeding environments explain the decline of southernmost European Atlantic salmon populations
(Peer reviewed; Journal article, 2019)The consistency of the global declining trend of Atlantic salmon (Salmo salar) populations suggests that climate-driven reduced survival and growth at sea are the main driving factors. The southernmost populations have ... -
Sub-arctic mosses and lichens show idiosyncratic responses to combinations of winter heatwaves, freezing and nitrogen deposition
(Peer reviewed; Journal article, 2023)Arctic ecosystems are increasingly exposed to extreme climatic events throughout the year, which can affect species performance. Cryptogams (bryophytes and lichens) provide important ecosystem services in polar ecosystems ... -
Prey predictability and preparation versus recovery breathing strategies in European shags Gulosus aristotelis (L.) diving in different habitats
(Peer reviewed; Journal article, 2023)A recent study on the diving behaviour of European shags (Gulosus aristotelis (L.)) foraging in kelp forests off rocky coasts of Norway suggests surface durations are related only to the duration of the preceding dive, and ... -
Feasibility of active handheld NDVI sensors for monitoring of lichen ground cover
(Peer reviewed; Journal article, 2023)Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- ... -
