The lineage-specific evolution of aquaporin gene clusters facilitated tetrapod terrestrial adaptation
(Peer reviewed; Journal article, 2014-11-26)A major physiological barrier for aquatic organisms adapting to terrestrial life is dessication in the aerial environment. This barrier was nevertheless overcome by the Devonian ancestors of extant Tetrapoda, but the origin ... -
Linking bacterial community structure to advection and environmental impact along a coast-fjord gradient of the Sognefjord, western Norway
(Peer reviewed; Journal article, 2017-12)Here we present novel data on bacterial assemblages along a coast-fjord gradient in the Sognefjord, the deepest (1308 m) and longest (205 km) ice-free fjord in the world. Data were collected on two cruises, one in November ... -
Linking dispersal connectivity to population structure and management boundaries for saithe in the Northeast Atlantic
(Journal article; Peer reviewed, 2021)Population connectivity is an increasingly important focal area for the understanding of how marine fish populations respond to anthropogenic pressures like climate change and fisheries. Our model species, the saithe ... -
Linking internal and external bacterial community control gives mechanistic framework for pelagic virus-to-bacteria ratios
(Peer reviewed; Journal article, 2016-11)For more than 25 years, virus-to-bacteria ratios (VBR) have been measured and interpreted as indicators of the importance of viruses in aquatic ecosystems, yet a generally accepted theory for understanding mechanisms ... -
Lipid production in nannochloropsis gaditana during nitrogen starvation
(Peer reviewed; Journal article, 2019)The microalga Nannochloropsis gaditana is a natural producer of triacylglycerol (TAG) and the omega-3 fatty acid eicosapentaenoic acid (EPA). TAG accumulation is induced by nitrogen starvation. The biomass-specific photon ... -
Lipid transporters and receptor in salmon louse (Lepeophtheirus salmonis) : Effect of RNAi Knockdown on oogenesis, embryonal development and larval maturation
(Doctoral thesis, 2021-04-23)The salmon louse, Lepeophtheirus salmonis, is a marine ectoparasite of salmonids in the Northern Hemisphere. At present, salmon louse infestation is considered as one of the biggest challenges in the salmon farming industry, ... -
Lithistid demosponges of the North Atlantic : Taxonomy, Diversity and Biogeographic Patterns
(Doctoral thesis, 2020-11-27)Sponges, phylum Porifera Grant, 1836, comprise a group of benthic filter-feeding organisms, which are one of the oldest living groups of metazoans on Earth. Currently, four classes are recognized within the Phylum, of which ... -
Liver transcriptome analysis of Atlantic cod (Gadus morhua) exposed to PCB 153 indicates effects on cell cycle regulation and lipid metabolism
(Peer reviewed; Journal article, 2014-06-17)Background: Polychlorinated biphenyls (PCBs) are persistent organic pollutants (POPs) with harmful effects in animals and humans. Although PCB 153 is one of the most abundant among PCBs detected in animal tissues, its ... -
Localizing the Sustainable Development Goals for Marine and Coastal Management in Norway: A Venture Overdue
(Chapter, 2022)Meeting global challenges requires regional and local alignment of institutional and business practices. The purpose of our work is to understand, using qualitative systems analysis, how the Sustainable Development Goals ... -
Localizing the United Nations Sustainable Development Goals in northern Norway: Transdisciplinary approaches for sustainable coastal development
(Doctoral thesis, 2023-12-01)I 2015 lanserte FN «2030 Agenda for Sustainable Development» med et unikt og ambisiøst rammeverk for global bærekraft som inkluderer 17 bærekraftsmål (SDG). Siden den gang har mange ledere over hele verden på lokalt, ... -
Long distance dispersal and oceanographic fronts shape the connectivity of the keystone sponge Phakellia ventilabrum in the deep northeast Atlantic
(Journal article; Peer reviewed, 2023)Little is known about dispersal in deep-sea ecosystems, especially for sponges, which are abundant ecosystem engineers. Understanding patterns of gene flow in deep-sea sponges is essential, especially in areas where rising ... -
Long-range transcriptional regulation of vertebrate developmental genes and the evolution of genome architecture
(Doctoral thesis, 2008-09-12)Despite the recent massive progress in production of vertebrate genome sequence data and large-scale efforts to completely annotate the human genome, we still have scant knowledge of the principles that built genomes in ... -
Long-term change in a behavioural trait: truncated spawning distribution and demography in Northeast Arctic cod
(Peer reviewed; Journal article, 2015-04)Harvesting may be a potent driver of demographic change and contemporary evolution, which both may have great impacts on animal populations. Research has focused on changes in phenotypic traits that are easily quantifiable ... -
Long-term changes in life-history traits of Norwegian spring-spawning herring
(Doctoral thesis, 2019)Life-history traits are key determinants of populations’ dynamics. Those traits are susceptible to natural selection and are therefore sensitive to the mortality regime and the selection pattern a population experience. ... -
Long-Term Climate Regime Modulates the Impact of Short-Term Climate Variability on Decomposition in Alpine Grassland Soils
(Peer reviewed; Journal article, 2018-12)Decomposition of plant litter is an important process in the terrestrial carbon cycle and makes up approximately 70% of the global carbon flux from soils to the atmosphere. Climate change is expected to have significant ... -
Long-term disturbance dynamics and resilience of tropical peat swamp forests
(Peer reviewed; Journal article, 2015-01)1. The coastal peat swamp forests of Sarawak, Malaysian Borneo, are undergoing rapid conversion, predominantly into oil palm plantations. This wetland ecosystem is assumed to have experienced insignificant disturbance in ... -
Long-term dynamics of wadi trees in a hyper-arid cultural landscape
(Doctoral thesis, 2007-03-09)This study focuses on the long-term dynamics of wadi (dry river valley) trees, in particular Acacia tortilis (Forssk.) Hayne, in the hyper-arid Eastern Desert of Egypt. The project was motivated by the importance of drought ... -
Long-term ecological responses of a lowland dipterocarp forest to climate changes and nutrient availability
(Journal article; Peer reviewed, 2023)Understanding the long-term impact of projected climate change on tropical rainforests is critical given their central role in the Earth's system. Palaeoecological records can provide a valuable perspective on this problem. ... -
