(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2007)Climate influences a population through a variety of processes, including reproduction, growth, migration patterns and phenology. Climate may operate either directly through metabolic and reproductive processes or indirectly ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background:The implementation of high throughput sequencing for exploring biodiversity poses high demands on bioinformatics applications for automated data processing. Here we introduce CLOTU, an online and open access ...

(Master thesis / Hovedoppgave, 1971)Coccolithus huxleyi er en av de vanligste coccolithoforider, den har en svært vid utbredelse. På norskekysten trekker den til seg oppmerksomheten ved lokale masseoppblomstringer med misfarging av sjøen til følge. I den ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Ecological interactions determine the structure and dynamics of communities and their responses to the environment. Understanding the community-level effects of ecological interactions, such as intra- and interspecifc ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)The effect of mass extinctions on phylogenetic diversity and branching history of clades remains poorly understood in paleobiology. We examined the phylogenies of communities of digital organisms undergoing open-ended ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Assessing the role of weather in the dynamics of wildlife populations is a pressing task in the face of rapid environmental change. Rodents and ruminants are abundant herbivore species in most Arctic ecosystems, many of ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)The clupeid fish Sprattus sprattus was studied in a 150 m deep Norwegian fjord throughout an entire overwintering period during which the fjord froze over and a major water renewal occurred. A bottom-mounted (upward-facing) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Understanding the drivers of seasonal migration among large herbivores is crucial for management and conservation. The forage maturation hypothesis predicts migration even at low population density, due to the benefits of ...
-
(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, 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 ...
