(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)This study compares the structure of eelgrass (Zostera marina L.) meadows and associated food webs in two eelgrass habitats in Denmark, differing in exposure, connection to the open sea, nutrient enrichment and water ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Commercial fishing generally removes large and old individuals from fish stocks, reducing mean age and age diversity among spawners. It is feared that these demographic changes lead to lower and more variable recruitment ...

(Master thesis / Masteroppgave, 2016)Fragmentation of habitats is one of the major threats to biodiversity. Fragmentations will reduce connectivity and consequently affect the genetic population structure particularly in rivers. In the current study the genetic ...
-
(Master thesis / Masteroppgave, 2015)Nanoparticles are particles with at least one dimension between 1 and 100 nm. Due to their unique properties, gold nanoparticles (AuNPs) are used for drug delivery, diagnostics and cellular imaging, but there are concerns ...

Effect of historic aquaculture activity on copepod sensitivity to the combined exposure of copper and predation riskRestricted Access (Master thesis / Masteroppgave, 2022)Marine ecosystems are complex ecosystems in which organisms consciously face multiple stressors. Copepods, the most abundant zooplankton group has an integral role in the marine food web. They are exposed to multiple ...
-
(Master thesis / Masteroppgave, 2014)Interspecific hybridization has intrigued evolutionary biologists since Darwin s time. New genetic combinations can arise from hybridization, leading to offspring sometimes able to adapt to different niches than their ...

(Master thesis / Masteroppgave, 2018)Laminaria hyperborea is an important species of kelp comprising large kelp forests along the Norwegian coast. Large quantities of detritus from these forests are exported to other ecosystems. These exports could support ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Supplemental feeding of cervids during winter is a widespread management practice, but feeding may increase the risk of disease transmission. Therefore, legal regulations to limit supplemental feeding are often implemented ...
-
(Master thesis / Masteroppgave, 2015)Juncus bulbosus Growth Experiment performed over 13 weeks to establish its response to anoxic conditions over root system. 20 of 40 plants were grown hydroponically with oxygen deprived water supplied to the root system. ...

Effect of Terrestrial and Aquatic Dissolved Organic Matter on Uptake Rates of Teflubenzuron in the Ascidian Ciona intestinalisRestricted Access (Master thesis / Masteroppgave, 2022)In recent years, a darkening of aquatic environments has been observed and traced back to an increased input of terrestrial dissolved organic matter (tDOM). This is causing changes to light and nutrient dynamics, and shifts ...

The Effect of Transcorneal Electrical Stimulation on the Electroretinogram in Patients with Retinitis PigmentosaRestricted Access (Master thesis / Masteroppgave, 2013)Retinitis Pigmentosa (RP) is a progressive and degrading illness impairing the vision of all age groups [1-3]. The disease is caused by mutations which are affecting the photoreceptors and the retinal pigment epithelium ...

The Effect on Mutated Tau Expression in Higher Visual Areas on Visual Discrimination LearningRestricted Access (Master thesis / Masteroppgave, 2023)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A relic inshore reef ecosystem adjacent to the Fijian capital of Suva and another remote inshore reef were monitored monthly from July 2014 to July 2015 for coral recruitment, sedimentation rates, coral cover, temperature, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Seismic surveys are conducted worldwide to explore for oil and gas deposits and to map subsea formations. The airguns used in these surveys emit low-frequency sound waves. Studies on zooplankton responses to airguns report ...
