The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter ... -
Alien species in Norway: Results from quantitative ecological impact assessments
Sandvik, Hanno; Hilmo, Olga; Henriksen, Snorre; Elven, Reidar; Åsen, Per Arvid; Hegre, Hanne; Pedersen, Oddvar; Pedersen, Per Anker; Solstad, Heidi; Vandvik, Vigdis; Westergaard, Kristine Bakke; Ødegaard, Frode; Åström, Sandra Charlotte Helene; Elven, Hallvard; Endrestøl, Anders; Gammelmo, Øivind; Hatteland, Bjørn Arild; Solheim, Halvor; Nordén, Björn; Sundheim, Leif; Talgø, Venche; Falkenhaug, Tone; Gulliksen, Bjørn; Jelmert, Anders; Oug, Eivind; Sundet, Jan Henry; Forsgren, Elisabet; Finstad, Anders Gravbrøt; Hesthagen, Trygve H.; Nedreaas, Kjell Harald; Wienerroither, Rupert; Husa, Vivian; Fredriksen, Stein; Sjøtun, Kjersti; Steen, Henning; Hansen, Haakon; Hamnes, Inger Sofie; Karlsbakk, Egil; Magnusson, Christer; Ytrehus, Bjørnar; Pedersen, Hans Christian; Swenson, Jon; Syvertsen, Per Ole; Stokke, Bård Gunnar; Gjershaug, Jan Ove; Dolmen, Dag; Kjærstad, Gaute; Johnsen, Stein Ivar; Jensen, Thomas Correll; Hassel, Kristian; Gederaas, Lisbeth (Journal article, 2020)1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ... -
Discards of cod (Gadus morhua) in the Norwegian coastal fisheries: improving past and future estimates
Berg, Hilde Sofie Fantoft; Clegg, Thomas L; Blom, Geir; Kolding, Jeppe; Ono, Kotaro; Nedreaas, Kjell Harald (Journal article; Peer reviewed, 2022)Discarding can be an unknown source of biases and uncertainties in stock assessments. Discarding patterns and quantities vary so a routine methodology for estimating discards is important to give a better picture of total ... -
Fine-scale spatial variation of northern shrimp and Atlantic cod across three Norwegian fjord systems and implications for management
Zimmermann, Fabian; Tengvall, Jessica; Strand, Hans Kristian; Nedreaas, Kjell Harald; Thangstad, Trude Hauge; Husson, Berengere; Søvik, Guldborg (Journal article; Peer reviewed, 2023)The spatial complexity of coastal ecosystems represents a challenge for the management of inshore resources. Here we compared two large fjord systems in northern Norway that have been closed for all bottom trawling for 50 ... -
Gaussian mixture models reveal highly diverse targeting tactics in a coastal fishing fleet
Liu, Xiaozi; Hansen, Cecilie; Nedreaas, Kjell Harald; Stockhausen, Hagen; Heino, Mikko Petteri (Journal article; Peer reviewed, 2022)Fishermen make repeated choices with respect to when, where, and how to catch their target species. While these targeting tactics—and the factors shaping them—are known to fishers and some experts, knowledge about them is ... -
Geographic variation in gene flow from a genetically distinct migratory ecotype drives population genetic structure of coastal Atlantic cod (Gadus morhua L.)
Seliussen, Bjørghild Breistein; Dahle, Geir; Johansen, Torild; Besnier, Francois; Quintela, Maria; Jorde, Per Erik; Knutsen, Halvor; Westgaard, Jon-Ivar; Nedreaas, Kjell Harald; Farestveit, Eva; Glover, Kevin Alan (Journal article; Peer reviewed, 2022)Identifying how physical and biotic factors shape genetic connectivity among populations in time and space is essential to our understanding of the evolutionary trajectory as well as the management of marine species. ... -
Linking dispersal connectivity to population structure and management boundaries for saithe in the Northeast Atlantic
Myksvoll, Mari Skuggedal; Devine, Jennifer Ann; Quintela, Maria; Geffen, Audrey J.; Nash, Richard David Marriott; Sandvik, Anne Dagrun; Besnier, Francois; Saha, Atal; Dahle, Geir; Jansson, Eeva; Nedreaas, Kjell Harald; Johansen, Torild (Journal article; Peer reviewed, 2021)Population connectivity is an increasingly important focal area for the understanding of how marine fish populations respond to anthropogenic pressures like climate change and fisheries. Our model species, the saithe ... -
“Real-time” genetic monitoring of a commercial fishery on the doorstep of an MPA reveals unique insights into the interaction between coastal and migratory forms of the Atlantic cod
Johansen, Torild; Westgaard, Jon-Ivar; Seliussen, Bjørghild Breistein; Nedreaas, Kjell Harald; Dahle, Geir; Glover, Kevin; Kvalsund, Roger; Aglen, Asgeir (Peer reviewed; Journal article, 2017-05)With the decline of many of the world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” ...
