Optimal size at seaward migration in an anadromous salmonid
(Journal article; Peer reviewed, 2016)In this study, the probabilistic reaction norm was calculated for length at different ages of smolting before seaward migration of Atlantic salmon Salmo salar spawning in the Norwegian River Imsa. The reaction norm was ... -
Optimal timing of return migration in Atlantic salmon
(Peer reviewed; Journal article, 2024)In many populations of Atlantic salmon, individuals return to rivers months or even a year prior to spawning. This premature arrival in fresh water by far exceeds the time needed for upstream migrations to spawning areas. ... -
Optimization of dynamic soaring in a flap-gliding seabird affects its large-scale distribution at sea
(Peer reviewed; Journal article, 2022)Dynamic soaring harvests energy from a spatiotemporal wind gradient, allowing albatrosses to glide over vast distances. However, its use is challenging to demonstrate empirically and has yet to be confirmed in other seabirds. ... -
Optimizing the closure period for improved accuracy of chamber-based greenhouse gas flux estimates
(Peer reviewed; Journal article, 2024)Non-steady-state chambers are often used for greenhouse gas flux measurements, and while there are recommendations on how long to keep the chamber closed, it is less investigated to what extent the length of the chamber ... -
