Hva bestemmer egenskaper og økologisk funksjon i ålegrasenger?
(Research report, 2014)
Juni 2014 ble 27 ålegrasenger i Aust-Agder undersøkt for å analysere hvilke miljøfaktorer som bestemmer egenskaper som tetthet og høyde til ålegrasplanten i engene, og om enger med tett ålegrasvegetasjon er leveområde for ...
Relative importance of fisheries, trophodynamic and environmental drivers in a series of marine ecosystems
(Journal article; Peer reviewed, 2012-07-12)
Marine ecosystems are influenced by drivers that operate and interact over multiple scales, resulting in nonlinear or abrupt responses to perturbation. Because of the inherent complexity of marine ecosystems, progress ...
Kartlegging av fremmede marine arter i Hordaland
(DN-utredning;2-2012, Research report, 2012-03)
The method Rapid Coastal Survey was applied in a pilot project in the county of Hordaland in autumn 2010. The abundance of 21 introduced target species was investigated in 32 marinas in the area. No new species to ...
Kartlegging av fremmede marine arter i Rogaland
(DN-utredning;3-2012, Research report, 2012-03)
The method Rapid Coastal Survey was applied in 36 marinas in the county of Rogaland during five days in august 2010. 27 introduced species were targeted in this investigation. No new species to Norway was found, but ...
‘Double trouble’: the expansion of the Suez Canal and marine bioinvasions in the Mediterranean Sea
(Journal article; Peer reviewed, 2014-09-28)
Why do jellyfish bloom in Norwegian waters and what can be done to recover the ecosystems in the North Sea and on the Norwegian coast?
The ecosystems with their relationships between fish species and stocks, have been established by evolution for millions of years, but only during the last 50 years, the ecosystems in the North Sea and along the Norwegian ...
Instrumentation and handling effects on Antarctic fur seals (Arctocephalus gazella)
(Journal article; Peer reviewed, 2014-02-21)
The use of biologging instruments has greatly improved our understanding of the behaviour, physiology and ecology of free-ranging marine mammals. However, handling wild animals and attaching instruments to streamlined ...
Adaptation to Low Salinity Promotes Genomic Divergence in Atlantic Cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2015-05-20)
How genomic selection enables species to adapt to divergent environments is a fundamental question in ecology and evolution. We investigated the genomic signatures of local adaptation in Atlantic cod (Gadus morhua L.) along ...
A new goatfish of the genus Upeneus (Mullidae) from Lombok, Indonesia and first verified record of U. asymmetricus for the Indian Ocean

Upeneus lombok n. sp. is described from two specimens collected off Lombok, Indonesia, at depths of 54–76 m, and one subadult specimen from the local fish market at Tanjung Luar, Lombok. Four specimens of U. asymmetricus ...
Spring bloom nutrient dynamics in the Oslofjord
(Journal article; Peer reviewed, 2001-09-10)
Primary production and uptake rates of ammonium, nitrate and silicic acid were measured during the 1996 spring bloom in the Oslofjord, southern Norway, using isotope methodology (14C, 15N and 32Si). Chlorophyll a (chl a) ...
