Climate-driven changes in functional biogeography of Arctic marine fish communities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-14)
Climate change triggers poleward shifts in species distribution
leading to changes in biogeography. In the marine environment,
fish respond quickly to warming, causing community-wide reorganizations, which result in profound changes in ecosystem functioning. Functional biogeography provides a framework to address how
ecosystem functioning may be affected by climate change over
large spatial ...
Change in Fish Community Structure in the Barents Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
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 species rather than on whole ecosystems. In this paper, the objective is to describe the spatial and temporal changes in the Barents Sea fish community in the period 1992–2004 while ...
Climate change alters the structure of arctic marine food webs due to poleward shifts of boreal generalists
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-02)
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 to affect
arctic marine food web structure and ecosystem functioning substantially.
Here, we address structural changes at the food web level induced by poleward
shifts via ...
Increased functional diversity warns of ecological transition in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-07)
As temperatures rise, motile species start to redistribute to more suitable areas, potentially affecting the persistence of several resident species and altering biodiversity and ecosystem functions. In the Barents Sea, a hotspot for global warming, marine fish from boreal regions have been increasingly found in the more exclusive Arctic region. Here, we show that this shift in species distribution ...
Functional roles and redundancy of demersal Barents Sea fish: Ecological implications of environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-21)
When facing environmental change and intensified anthropogenic impact on marine ecosystems, extensive knowledge of how these systems are functioning is required in order to manage them properly. However, in high-latitude ecosystems, where climate change is expected to have substantial ecological impact, the ecosystem functions of biological species have received little attention, partly due to the ...
