(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Crustose lichen communities on rocks exhibit fascinating spatial mosaics resembling political maps of nations or municipalities. Although the establishment and development of biological populations are important themes in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background We have previously sequenced more than 500 kb of the duplicated MHC class I regions in Atlantic salmon. In the IA region we identified the loci for the MHC class I gene Sasa-UBA in addition to a ...
-
(Doctoral thesis / Doktoravhandling, 2010)In this thesis I have studied connectivity processes affecting the population structure of coastal cod on the Norwegian Skagerrak coast. I have focused on three aspects of the processes. Firstly the dynamics and the integrity ...
-
(Doctoral thesis / Doktoravhandling, 2011)The thesis introduces a new integrated approach to ecological and evolutionary modeling, the goal of which is to create an analytical platform for applied interdisciplinary researches. This Conspecific Community Dynamics ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background Following colonization of new habitats and subsequent selection, adaptation to environmental conditions might be expected to be rapid. In a mountain lake in Norway, Lesjaskogsvatnet, more than ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Atlantic salmon populations are reported to be declining throughout its range, raising major management concerns. Variation in adult fish abundance may be due to variation in survival, growth, and timing of life history ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background Evaluating the limits of adaptation to temperature is important given the IPCC-predicted rise in global temperatures. The rate and scope of evolutionary adaptation can be limited by low genetic ...
-
(Master thesis / Hovedoppgave, 2002)Cardiomyocyte contraction is controlled by the intracellular Ca2+ concentration ([Ca2+]i), which is regulated by L-type Ca2+ channels and by a Na+/Ca2+-exchanger. The Na+/Ca2+-exchanger translocates three Na+ and one Ca2+ ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)Background To conduct phylogeographic or population genetic studies, an adequate number of DNA markers for the focal species are required. Due to severe unavailability of genotype markers of any kind for ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)The present study is the first attempt to explore the rate, characteristics and legal reactions to neonaticide in Norway during the years 1990 – 2009. Potential incidents of neonaticide were identified through the national ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Delayed density-dependent demographic processes are thought to be the basis for multi-annual cyclic fluctuations in small rodent populations, but evidence for delayed density dependence of a particular demographic trait ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Spatio-temporal density-dependent processes are crucial regulatory factors for natural populations. However, there is a lack of studies addressing spatial density-dependence in fish growth. A previous investigation has ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background The incidence of bovine babesiosis, caused by Babesia divergens (Apicomplexa: Piroplasmida) has decreased markedly since the 1930 s, but may re-emerge as a consequence of climate change and ...
-
(Master thesis / Hovedoppgave, 2005)ABSTRACT Cell-based assays are useful and effective for biomonitoring and toxicity screening purposes, and there is a need for fast, routine and simple screening assays. An assay to detect the production of reactive oxygen ...
-
Diversity and community composition of root-associated fungi explored by high throughput sequencing (Doctoral thesis / Doktoravhandling, 2012)Interactions between plant roots and fungi are well known from most terrestrial ecosystems. Mycorrhizal association is the most prominent plant-fungi interaction, where the fungal partners increase the water and nutrient ...
-
(Doctoral thesis / Doktoravhandling, 2008)Cyanobakterier (=blågrønnalger) forekommer i nesten alle norske innsjøer, og masseoppblomstringer av dem har vist seg å være utbredt over hele verden. Et stort problem ved oppblomstringer av cyanobakterier er giftstoffene ...

(Doctoral thesis / Doktoravhandling, 2010)
-
(Doctoral thesis / Doktoravhandling, 2009)Pockmarks have now been recognised for nearly four decades, and are one of the most obvious and abundant structural features of the seafloor in some areas, yet there is still little knowledge of their influence on fauna ...
-
(Doctoral thesis / Doktoravhandling, 2008)This thesis investigates competition and ecological speciation by comparing habitat use, foraging ecology and physiology of two fish populations (Coregonus spp.) in a temperate lake. It demonstrates that dietary differences ...
-
(Doctoral thesis / Doktoravhandling, 2008)I dette arbeidet har vi utviklet molekylære metoder for simultant å måle forekomsten av ulike mikrober i komplekse samfunn. Koblet med økologisk analyse gir dette oss helt nye muligheter til å forstå hvordan bakteriesamfunn ...
