Benthic transition zones in the Atlantic gateway to a changing Arctic ocean
Jørgensen, Lis Lindal; Pecuchet, Laurene; Ingvaldsen, Randi Brunvær; Primicerio, Raul (Peer reviewed; Journal article, 2022)The biogeographic transition from boreal to Arctic marine communities entails a strong taxonomic and functional turnover. Communities living in these areas are being strongly affected by climate warming with rapid ... -
Change in Fish Community Structure in the Barents Sea
Aschan, Michaela; Fossheim, Maria; Greenacre, Michael; Primicerio, Raul (Journal article; Peer reviewed, 2013-04-29)Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial ... -
Changes in the Barents Sea fish community induced by environmental change and fishery
Aschan, Michaela; Fossheim, Maria; Primicerio, Raul (ICES CM documents;2009/ F:05, Working paper, 2009)A spatio-temporal analysis of Barents Sea survey data from the deeper parts of the Barents Sea shows a sudden change in fish community structure and abundance taking place in the mid 1980s and 1990s. The change in fish ... -
Climate change alters the structure of arctic marine food webs due to poleward shifts of boreal generalists
Kortsch, Susanne; Primicerio, Raul; Fossheim, Maria; Dolgov, Andrey V.; Aschan, Michaela (Journal article; Peer reviewed, 2015-09-07)Climate-driven poleward shifts, leading to changes in species composition and relative abundances, have been recently documented in the Arctic. Among the fastest moving species are boreal generalist fish which are expected ... -

Effects of life-history traits and network topological characteristics on the robustness of marine food webs
Merillet, Laurene; Robert, Marianne; Hernvann, Pierre-Yves; Pecuchet, Laurene; Pavoine, Sandrine; Mouchet, Maud; Primicerio, Raul; Kopp, Dorothée (Peer reviewed; Journal article, 2022)Management targets for biodiversity preservation are shifting from individual species to an ecosystem-wide focus. Indeed, the perturbation analysis of interaction networks, such as food webs, better captures the response ... -
Food-web structure varies along environmental gradients in a high-latitude marine ecosystem
Kortsch, Susanne; Primicerio, Raul; Aschan, Michaela; Lind, Sigrid; Dolgov, Andrey V.; Planque, Benjamin (Journal article; Peer reviewed, 2018)Large‐scale patterns in species diversity and community composition are associated with environmental gradients, but the implications of these patterns for food‐web structure are still unclear. Here, we investigated how ... -
