(Master thesis, 1985) -
Vertical distribution and trophic interactions of zooplankton and fish in Masfjorden, Norway
(Peer reviewed; Journal article, 1990)The distribution, biomass, and predator-prey relationships of the pelagic assemblage in Masfjorden, western Norway, was studied in January 1989. The pelagic biomass was dominated by particulate organic matter. Biomasses ... -
Rapid and reliable cloning of PCR products
(Peer reviewed; Journal article, 1991-08-08) -
The zebrafish homeobox gene Hox(zf-114): primary structure, expression pattern and evolutionary aspects
(Peer reviewed; Journal article, 1992)It is gradually becoming accepted that vertebrate homeobox genes, like their counterparts in Drosophila, are crucial for normal development of the embryo. Most vertebrate homeoboxes reported so far are related to the ... -
Ecosystem model for evaluating potential cod production in a west Norwegian fjord
(Peer reviewed; Journal article, 1992-12-08)The carrying capacity for cod in a Norwegian fjord was analysed by means of a simulation model. Four age groups of cod were represented as well as the maln prey groups labrids, gobies and benthic organisms. These groups ... -
Dominating sublittoral fish species in a west Norwegian fjord and their trophic links to cod (Gadus morhua L.)
(Peer reviewed; Journal article, 1993)The fish fauna in the sublittoral habitat of Masfjorden, western Norway, has been studied in order to reveal survival and growth prospects of released juvenile cod in a large-scale stock enhancement experiment. Seasonal ... -
Korleis gjekk det med havbeiteforsøket med torsk i Masfjorden?
(Journal article, 1994) -
Periodicity of otolith check formation in the juvenile plaice Pleuronectes platessa
(Belle W.Baruch Library in Marine Science, Chapter; Conference object; Peer reviewed, 1995)Juvenile (Pleuronectes platessa L.) were sampled in the intertidal zone of Port Erin Bay (Isle of Man, Irish Sea) by push-net in the summers of 1990 and 1992. Check formation on the sagittal otoliths was examined to test ... -
Fish zona radiata (eggshell) protein: A sensitive biomarker for environmental estrogens
(Peer reviewed; Journal article, 1997-04)Environmental estrogens have recently caused great concern because of their ability to mimic natural hormones and influence vital endocrine functions in humans and wildlife. The induction of vitellogenin (Vtg) synthesis ... -
Effects of formaldehyde and ethanol preservation on body and otoliths of Maurolicus muelleri and Benthosema glaciale
(Peer reviewed; Journal article, 1998)First of its kind, this study examines effects of preservatives on otoliths as well as on fish size and weight. Effects of 200 days of preservation in 4 % seawater formaldehyde solution and 80 % ethanol were investigated ... -
Effects of temperature and natural disturbance on growth, reproduction, and population density in the alpine annual hemiparasite euphrasia frigida
(Peer reviewed; Journal article, 1999)The effects of temperature and "natural disturbance" on growth, seed production, and population density in the facultative hemiparasitic annual Euphrasia frigida (Scrophulariaceae) were examined in the middle alpine zone ... -
Breeding system, insect flower visitation, and floral traits of two alpine cerastium species in Norway
(Peer reviewed; Journal article, 1999)The pollination and reproductive ecology of Saxifraga stellaris was investigated in alpine southwest Norway. A breeding system analysis, with performance of controlled crosses, revealed that S. stellaris is self-compatible ... -
An expanded calibration model for inferring lakewater and air temperatures from fossil chironomid assemblages in northern Fennoscandia
(Peer reviewed; Journal article, 1999)Chironomid-temperature inference models based on an expanded data set of surface-sediment and limnological data from 53 Subarctic lakes in northern Fennoscandia have been developed using eight different numerical techniques, ... -
Responses of tundra plants to experimental warming : meta-analysis of the international tundra experiment
(Peer reviewed; Journal article, 1999)The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using a common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ... -
Wind to insect pollination ratios and floral traits in five alpine Salix species
(Peer reviewed; Journal article, 1999)This study examines the ratio of wind to insect pollination of five alpine-arctic Salix species and possible correlations between plant traits and this ratio. The field work was done in an alpine area in southwest Norway, ... -
Change and variation in a hyer-arid cultural landscape: A merhodological approach using remote sensing timeseries (Landsat MSS and TM, 1973-1996) from the Wadi vegetation of the eastern desert of Egypt
(Master thesis, 1999)Nine wadi localities in a hyper-arid environment have been registered in the field and studied using earth observation data. Branch height, crown – and trunk – diameter, and indicators of land-use such as present traces ...
