A framework for results-based management in fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-30)
We present a framework for results-based management (RBM) of commercial fisheries. The core idea of RBM is to reduce
micromanagement by delegating management responsibility to resource users. The RBM framework represents an industrial organization approach to co-management and comprises three defining processes, conducted by three independent “agents”:
(i) an “authority” defines specific and ...
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 ...
Functional diversity of the Barents Sea fish community
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
This paper provides the first assessment of the functional diversity (FD) of the Barents Sea fish community. FD is recognized as an important driver of ecosystem functions and, thus, governs the adaptability of ecosystems in the face of disturbance. We integrate ecosystem survey data with an extensive trait matrix and show that fish FD displayed large spatial variation. The study period (2004 to ...
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 ...

Results based management in fisheries: Delegating responsibility to resource users
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-10-31)
While the notion of results based management has been devoted recent attention in the context of
reforming European fisheries management, it remains unclear what it entails. A conceptual model of
results based management in fisheries is proposed as a way for public authorities to delegate specific
management and documentation responsibilities to resource users. The model comprises three ...
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 ...
Participatory planning and decision support for ecosystem based fisheries management of the west coast of Scotland
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-14)
Mixed fisheries and the marine ecosystems that sustain them are complex entities and involve multiple and potentially conflicting management objectives and stakeholder interests. The presence of multiple trade-offs complicates the identification of strategies that satisfy various policy requirements while being acceptable to affected stakeholder groups. This creates a demand for tools and processes ...
The role of marine mammals in the Barents Sea foodweb
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-26)
Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available ...
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 ...
