Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth

Autor: Tom J. Langbehn, Johanna M. Aarflot, Jennifer J. Freer, Øystein Varpe

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 a two-step hurdle regression

Light and energetics at seasonal extremes limit poleward range shifts

Autor: Gabriella Ljungström, Tom J. Langbehn, Christian Jorgensen

Publikováno v: Nature Climate Change. 11:530-536

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 winters. In contrast to temperature, this latitudinal gradient in light seasonality is not af

Butler, W.; Guðmundsdóttir, L.; Logemann, K.; Langbehn, T.; Marteinsdóttir, G.: Egg size and density estimates for three gadoids in Icelandic waters and their implications for the vertical distribution of eggs along a stratified water column. In: Journal of Marine Systems. Vol. 204 (2020) 103290. (DOI: /10.1016/j.jmarsys.2019.103290)

The vertical distribution of fish eggs can have important consequences for recruitment through its influence on dispersal trajectories and thus connectivity between spawning and nursery locations. Egg density and size are key parameters for the model

Collapses and regime changes are pervasive in complex systems (such as marine ecosystems) governed by multiple stressors. The demise of Atlantic cod ( Gadus morhua ) stocks constitutes a text book example of the consequences of overexploiting marine
