Cascading effects of mass mortality events in Arctic marine communities
Langangen, Øystein; Ohlberger, Jan; Stige, Leif C.; Durant, Joel M.; Ravagnan, Elisa; Stenseth, Nils C.; Hjermann, Dag Ø. (Journal article; Peer reviewed, 2017)Mass mortality events caused by pulse anthropogenic or environmental perturbations (e.g., extreme weather, toxic spills or epizootics) severely reduce the abundance of a population in a short time. The frequency and impact ... -
Individual heterogeneity and early life conditions shape growth in a freshwater top predator
Nater, Chloé Rebecca; Rustadbakken, Atle; Ergon, Torbjørn; Langangen, Øystein; Moe, S. Jannicke; Vindenes, Yngvild; Vøllestad, Leif Asbjørn; Aass, Per (Journal article; Peer reviewed, 2018)Body size can have profound impacts on survival, movement, and reproductive schedules shaping individual fitness, making growth a central process in ecological and evolutionary dynamics. Realized growth is the result of a ... -
Influence of larval transport and temperature on recruitment dynamics of North Sea cod (Gadus morhua) across spatial scales of observation
Romagnoni, Giovanni; Kvile, Kristina Øie; Dagestad, Knut Frode; Eikeset, Anne Maria; Kristiansen, Trond; Stenseth, Nils Christian; Langangen, Øystein (Peer reviewed; Journal article, 2020)The survival of fish eggs and larvae, and therefore recruitment success, can be critically affected by transport in ocean currents. Combining a model of early‐life stage dispersal with statistical stock–recruitment models, ... -
Sensitivity of modelled North Sea cod larvae transport to vertical behaviour, ocean model resolution and interannual variation in ocean dynamic
Kvile, Kristina Øie; Romagnoni, Giovanni; Dagestad, Knut-Frode; Langangen, Øystein; Kristiansen, Trond (Journal article; Peer reviewed, 2018)Transport with ocean currents affects the spatial distribution and survival of fish eggs and larvae and thereby population connectivity. Biophysical models are commonly used to understand these dynamics. Advancements such ... -
Size‐ and stage‐dependence in cause‐specific mortality of migratory brown trout
Nater, Chloe Rebecca; Vindenes, Yngvild; Aas, Per; Cole, Diana; Langangen, Øystein; Moe, S. Jannicke; Rustadbakken, Atle; Turek, Daniel; Vøllestad, Leif Asbjørn; Ergon, Torbjørn (Peer reviewed; Journal article, 2020)Evidence‐based management of natural populations under strong human influence frequently requires not only estimates of survival but also knowledge about how much mortality is due to anthropogenic vs. natural causes. This ...
