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 ... -
Ecosystem model for evaluating potential cod production in a west Norwegian fjord
(Peer reviewed; Journal article, 1992-12-08)The carrying capacity for cod in a Norwegian fjord was analysed by means of a simulation model. Four age groups of cod were represented as well as the maln prey groups labrids, gobies and benthic organisms. These groups ... -
Ecosystem Resilience and Threshold Response in the Gala´pagos Coastal Zone
(Peer reviewed; Journal article, 2011-07-21)Background: The Intergovernmental Panel on Climate Change (IPCC) provides a conservative estimate on rates of sea-level rise of 3.8 mm yr21 at the end of the 21st century, which may have a detrimental effect on ecologically ... -
Ecosystem services show variable responses to future climate conditions in the Colombian páramos
(Journal article; Peer reviewed, 2021)Background: The páramos, the high-elevation ecosystems of the northern Andes, are well-known for their high species richness and provide a variety of ecosystem services to local subsistence-based communities and regional ... -
An ecosystem-scale litter and microplastics monitoring plan under the Arctic Monitoring and Assessment Programme (AMAP)
(Journal article; Peer reviewed, 2022)Lack of knowledge on levels and trends of litter and microplastics in the Arctic, is limiting our understanding of the sources, transport, fate, and effects is hampering global activities aimed at reducing litter and ... -
Ecotypes or Genotypes? The Status of the Currently Recognized Infraspecific Taxa of Acacia tortilis (Forssk.) : Hayne Growing in the Red Sea Hills, Sudan and Egypt
(Doctoral thesis, 2007-12-07)This study focuses on the Acacia tortilis species complex and the taxonomic relationship among its currently recognized infraspecific (A. tortilis ssp. tortilis, ssp raddiana and ssp. spirocarpa) in the Red Sea Hills of ... -
Ectopic epithelial cell clusters in salmonid intestine are associated with inflammation
(Peer reviewed; Journal article, 2018-06-11)An epizootic incidence of intestinal adenocarcinomas was reported in brood fish of Atlantic salmon (Salmo salar L.) in 2009. The condition was associated with a specific diet inducing enteritis and morphological changes. ... -
