Sea‐ice loss boosts visual search: fish foraging and changing pelagic interactions in polar oceans by Langbehn, Tom J., Varpe, Øystein

“…Light is a central driver of biological processes and systems. Receding sea ice changes the lightscape of high‐latitude oceans and more light will penetrate…”

Enlightening the ocean’s twilight zone by Kaartvedt, Stein, Langbehn, Tom J, Aksnes, Dag L

“…Abstract By definition, the mesopelagic twilight zone extends from 200 to 1000 m depth. Rather than confining the twilight zone to a certain depth interval, we…”

Light and energetics at seasonal extremes limit poleward range shifts by Ljungström, Gabriella, Langbehn, Tom J., Jørgensen, Christian

“…Seasonality in light becomes increasingly extreme at high latitudes, both in terms of the diel light–dark cycle and the duration of light summers and dark…”

Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth by Langbehn, Tom J., Aarflot, Johanna M., Freer, Jennifer J., Varpe, Øystein

“…Changes in the community size structure of Arctic copepods toward smaller and less fat individuals or species have been linked to environmental changes. The…”

Poleward distribution of mesopelagic fishes is constrained by seasonality in light by Langbehn, Tom J., Aksnes, Dag L., Kaartvedt, Stein, Fiksen, Øyvind, Ljungström, Gabriella, Jørgensen, Christian, Bates, Amanda

“…Aim Mesopelagic fishes have a near‐global distribution in the upper 1,000 m from tropical to sub‐Arctic oceans across temperature regimes. Yet, their abundance…”

Light comfort zone in a mesopelagic fish emerges from adaptive behaviour along a latitudinal gradient by Langbehn, TJ, Aksnes, DL, Kaartvedt, S, Fiksen, Ø, Jørgensen, C

“…Throughout the oceans, small fish and other micronekton migrate between daytime depths of several hundred meters and near-surface waters at night. These diel…”
