Activity patterns of wild European lobster Homarus gammarus in coastal marine reserves: implications for future reserve design

Moland, Even; Olsen, Esben Moland; Knutsen, Halvor; Knutsen, Jan Atle; Enersen, Svein Erik; André, Carl; Stenseth, Nils Christian (Journal article; Peer reviewed, 2011-05-16)

European lobster Homarus gammarus in Norway has been in decline over the last 30 to 40 yr, and the species is currently red listed according to International Union for Conservation of Nature criteria. In 2006, experimental ...

Behavioral responses of Atlantic cod to sea temperature changes

Freitas, Carla; Olsen, Esben Moland; Moland, Even; Ciannelli, Lorenzo; Knutsen, Halvor (Journal article; Peer reviewed, 2015-04-17)

Catch-and-release of Atlantic cod (Gadus morhua): post-release behaviour of acoustically pretagged fish in a natural marine environment

Ferter, Keno; Hartmann, Klaas; Kleiven, Alf Ring; Moland, Even; Olsen, Esben Moland (Journal article; Peer reviewed, 2014-10-07)

Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, ...

Cod at drift in the North Sea

Huserbråten, Mats Brockstedt Olsen; Moland, Even; Albretsen, Jon (Journal article; Peer reviewed, 2018)

There has been a large-scale geographical re-distribution of the North Sea cod stock over the past century, and recent surveys indicate a north-eastern modal distribution. Here we assess the consequences of the contemporary ...

Conservation, Spillover and Gene Flow within a Network of Northern European Marine Protected Areas

Huserbråten, Mats Brockstedt Olsen; Moland, Even; Knutsen, Halvor; Olsen, Esben Moland; André, Carl; Stenseth, Nils Chr. (Journal article; Peer reviewed, 2013-09-06)

To ensure that marine protected areas (MPAs) benefit conservation and fisheries, the effectiveness of MPA designs has to be evaluated in field studies. Using an interdisciplinary approach, we empirically assessed the design ...

Conservation, Spillover and Gene Flow within a Network of Northern European Marine Protected Areas

Huserbråten, Mats Brockstedt Olsen; Moland, Even; Knutsen, Halvor; Olsen, Esben Moland; André, Carl; Stenseth, Nils Christian (Peer reviewed; Journal article, 2013)

To ensure that marine protected areas (MPAs) benefit conservation and fisheries, the effectiveness of MPA designs has to be evaluated in field studies. Using an interdisciplinary approach, we empirically assessed the design ...

Demographic responses to protection from harvesting in a long-lived marine species

Fernández-Chacón, Albert; Buttay, Lucie; Moland, Even; Knutsen, Halvor; Olsen, Esben Moland (Peer reviewed; Journal article, 2021)

Marine protected areas (MPAs) are usually considered to have positive effects on the recovery of over-exploited populations. However, resolving the extent to which MPAs function according to their conservation goals requires ...

Depletion of coastal predatory fish sub-stocks coincided with the largest sea urchin grazing event observed in the NE Atlantic

Norderhaug, Kjell Magnus; Nedreaas, Kjell Harald; Huserbråten, Mats; Moland, Even (Peer reviewed; Journal article, 2020)

In this contribution, we propose fishery driven predator release as the cause for the largest grazing event ever observed in the NE Atlantic. Based on the evolving appreciation of limits to population connectivity, published ...

Disentangling structural genomic and behavioral barriers in a sea of connectivity

Barth, Julia Maria Isis; Villegas-Ríos, David; Freitas, Carla; Moland, Even; Star, Bastiaan; André, Carl; Knutsen, Halvor; Bradbury, Ian; Dierking, Jan; Petereit, Christoph; Righton, David; Metcalfe, Julian; Jakobsen, Kjetill Sigurd; Olsen, Esben Moland; Jentoft, Sissel (Journal article; Peer reviewed, 2019)

Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing ...

Disparate movement behavior and feeding ecology in sympatric ecotypes of Atlantic cod

Kristensen, Martin Lykke; Olsen, Esben Moland; Moland, Even; Knutsen, Halvor; Grønkjær, Peter; Koed, Anders; Källo, Kristi; Aarestrup, Kim (Peer reviewed; Journal article, 2021)

Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur ...

Distribution and diversity of fish species along the Sudanese Red Sea coast based on three combined trap and gillnet surveys

Olsen, Erik Joel Steinar; Axelsen, Bjørn Erik Eversvik; Moland, Even; Utne-Palm, Anne Christine; Elamin, Elamin Mohammed; Mukhtar, Motassim Ali; Saleh, Adel Mohamed; Elamin, Sheikheldin Mohamed; Iragi, Mohamed Abdelhameed; Gumaa, Said Gumaa Fadul (Peer reviewed; Journal article, 2021)

On the western shore of the semi-enclosed coral-reef rich Red Sea, the 850 km coastline of the Red Sea State of the Republic of Sudan provides livelihoods to artisanal fishers, but the present state of the living natural ...
