East Asian summer monsoon precipitation variability since the last deglaciation
(Peer reviewed; Journal article, 2015-06-18)The lack of a precisely-dated, unequivocal climate proxy from northern China, where precipitation variability is traditionally considered as an East Asian summer monsoon (EASM) indicator, impedes our understanding of the ... -
The East Greenland Current studied with CFCs and released sulphur hexafluoride
(Journal article, 2005-03)The distribution and evolution of water masses along the East Greenland Current (EGC) from south of the Fram Strait to the Denmark Strait were investigated using chlorofluorocarbons (CFCs) and the released tracer sulphur ... -
The East Greenland Current: Structure and Variability
(Master thesis, 2004) -
Eastern boundary circulation and hydrography off Angola. Building Angolan oceanographic capacities
(Peer reviewed; Journal article, 2018-09-06)The eastern boundary region off Angola encompasses a highly productive ecosystem important for the food security of the coastal population. The fish-stock distribution, however, undergoes large variability on intraseasonal, ... -
The ecdysone receptor (EcR) is a major regulator of tissue development and growth in the marine salmonid ectoparasite, Lepeophtheirus salmonis (Copepoda, Caligidae)
(Peer reviewed; Journal article, 2016-08)The function of the ecdysone receptor (EcR) during development and molting has been thoroughly investigated in some arthropods such as insects but rarely in crustacean copepods such as the salmon louse Lepeophtheirus ... -
ECKOchain: A FAIR blockchain-based database for long-term ecological data
(Journal article; Peer reviewed, 2024)Open data practices in ecology are increasingly accepted, yet primary long-term ecological data remain hard to find. Barriers preventing open long-term ecological data include social and economic constructs such as a sense ... -
Eco-friendly Egyptian blue (CaCuSi4O10) dye for luminescent solar concentrator applications
(Journal article; Peer reviewed, 2023)This study focuses on synthesizing the heavy metal-free ancient Egyptian blue (EB; CaCuSi4O10) dye using a facile ceramic method for luminescent solar concentrator (LSC) application. XRD, SEM and EDX results confirmed that ... -
Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci
(Journal article; Peer reviewed, 2020)Atlantic herring is widespread in North Atlantic and adjacent waters and is one of the most abundant vertebrates on earth. This species is well suited to explore genetic adaptation due to minute genetic differentiation at ... -
Ecological and evolutionary dynamics of interconnectedness and modularity
(Peer reviewed; Journal article, 2018-01-23)In this contribution, we develop a theoretical framework for linking microprocesses (i.e., population dynamics and evolution through natural selection) with macrophenomena (such as interconnectedness and modularity within ... -
Ecological and evolutionary effects of harvesting: lessons from the candy-fish experiment
(Peer reviewed; Journal article, 2013-11)Understanding the challenges of sustainable fisheries management is not easy for non-specialists, and even many specialists fail to appreciate the potential evolutionary consequences of harvest. We propose candy-fish ... -
Ecological Consequences of Ash Dieback in Western Norway
(Master thesis, 2021-06-30) -
Ecological load and balancing selection in circumboreal barnacles
(Journal article; Peer reviewed, 2021)Acorn barnacle adults experience environmental heterogeneity at various spatial scales of their circumboreal habitat, raising the question of how adaptation to high environmental variability is maintained in the face of ... -
Ecological memory at millennial time-scales: the importance of data constraints, species longevity and niche features
(Peer reviewed; Journal article, 2020)Ecological memory describes how antecedent conditions drive the dynamics of an ecological system. Palaeoecological records are paramount to understand ecological memory at millennial time‐scales, but the concept is widely ... -
Ecological Momentary Assessment in Internet-Delivered Psychological Treatments using Wearable Technology
(Master thesis, 2022-06-01)The growing prevalence of mental health problems is a global concern. Current psychological treatments are effective for a wide range of mental health problems. Yet, treatments today fall short with regards to scalability ... -
The ecological profile of Atlantic salmon escapees entering a river throughout an entire season: Diverse in escape history and genetic background, but frequently virus-infected
(Peer reviewed; Journal article, 2017-05)In 2014, 129 farmed salmon escapees captured in an upstream-migration trap located in the river Etne, western Norway, were investigated for viral infections, age at escape, size, and genetic composition. The frequency of ... -
Ecological ramifications of adaptation to size-selective mortality
(Journal article; Peer reviewed, 2021)Size-selective mortality due to harvesting is a threat to numerous exploited species, but how it affects the ecosystem remains largely unexplored. Here, we used a pond mesocosm experiment to assess how evolutionary responses ... -
Ecological significance of extracellular vesicles in modulating host-virus interactions during algal blooms
(Journal article; Peer reviewed, 2021)Extracellular vesicles are produced by organisms from all kingdoms and serve a myriad of functions, many of which involve cell-cell signaling, especially during stress conditions and host-pathogen interactions. In the ... -
Ecology and genomic diversity of iron-oxidizing bacteria at Arctic deep-sea hydrothermal vents: Lessons from genome-resolved metagenomics and microscopy
(Doctoral thesis, 2024-05-08)Jernoksiderende bakterier er globalt utbredt og har betydelig innvirkning på syklusen av jern i miljøet. Imidlertid har få slike bakterier blitt dyrket i laboratoriet og det finnes lite kunnskap om hvordan ulike miljøforhold ... -
Ecology of testate amoebae (Protista) in south-central Alaska peatlands: building transfer-function models for palaeoenvironmental studies
(Peer reviewed; Journal article, 2006)Testate amoebae are valuable indicators of peatland hydrology and have been used in many palaeoclimatic studies in peatlands. Because the species' ecological optima may vary around the globe, the development of transfer ... -
Ecosystem consequences of multi-trait response to environmental changes in Japanese medaka, Oryzias latipes
(Journal article; Peer reviewed, 2020)Intraspecific trait variation has large effects on the ecosystem and is greatly affected by human activities. To date, most studies focused on single-trait analyses, while considering multiple traits is expected to better ...
