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 ... -

Climate-Driven Ichthyoplankton Drift Model Predicts Growth of Top Predator Young
Myksvoll, Mari Skuggedal; Erikstad, Kjell E.; Barrett, Robert T.; Sandvik, Hanno; Vikebø, Frode (Journal article; Peer reviewed, 2013-11-12)Climate variability influences seabird population dynamics in several ways including access to prey near colonies during the critical chick-rearing period. This study addresses breeding success in a Barents Sea colony of ... -
Modelled drift patterns of fish larvae link coastal morphology to seabird colony distribution
Sandvik, Hanno; Barrett, Robert T; Erikstad, Kjell E; Myksvoll, Mari Skuggedal; Vikebø, Frode Bendiksen; Yoccoz, Nigel Gilles; Anker-Nilssen, Tycho; Lorentsen, Svein-Håkon; Reiertsen, Tone; Skardhamar, Jofrid; Skern-Mauritzen, Mette; Systad, Geir Helge (Journal article; Peer reviewed, 2016-05-13)Colonial breeding is an evolutionary puzzle, as the benefits of breeding in high densities are still not fully explained. Although the dynamics of existing colonies are increasingly understood, few studies have addressed ... -

Seabird−fish interactions: the fall and rise of a common guillemot Uria aalge population
Erikstad, Kjell E.; Reiertsen, Tone Kristin; Barrett, Robert T.; Vikebø, Frode; Sandvik, Hanno (Journal article; Peer reviewed, 2013-02-14)A major challenge in population ecology is the prediction of population responses to environmental variance. Food availability has long been hypothesized to play a major role in regulating seabird populations. In general, ... -
