Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth
Langbehn, Tom; Aarflot, Johanna Myrseth; Freer, Jennifer J.; Varpe, Øystein (Journal article; Peer reviewed, 2023)Changes in the community size structure of Arctic copepods toward smaller and less fat individuals or species have been linked to environmental changes. The underpinning mechanisms are, however, poorly understood. We use ... -
What we do in the dark: Prevalence of omnivorous feeding activity in Arctic zooplankton during polar night
Kunisch, Erin; Graeve, Martin; Gradinger, Rolf Rudolf; Flores, Hauke; Varpe, Øystein; Bluhm, Bodil (Journal article; Peer reviewed, 2023)During the productive polar day, zooplankton and sea-ice amphipods fulfill a critical role in energy transfer from primary producers to higher trophic-level species in Arctic marine ecosystems. Recent polar night studies ...
