Metabolomic and genomic investigation of two North-Norwegian cyanobacterial isolates for bioprospecting of new compounds
(Master thesis; Mastergradsoppgave, 2022-02-15)Cyanobacteria are an excellent source of bioactive natural products that can be used in the development of new medicinal drugs. The cyanobacterial genus Nostoc have proven to be prolific producers of molecules with exciting bioactivities, including anti-bacterial, anti-fungal, and anti-cancerous. This feature combined with the Nostoc’s complex life cycle and sizeable genomes make them interesting ... -
Lead in the marine environment: concentrations and effects on invertebrates
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-17)Lead (Pb) is a non-essential metal naturally present in the environment and often complexed with other elements (e.g., copper, selenium, zinc). This metal has been used since ancient Egypt and its extraction has grown in the last centuries. It has been used until recently as a fuel additive and is currently used in the production of vehicle batteries, paint, and plumbing. Marine ecosystems are sinks ... -
Uniform bathymetric zonation of marine benthos on a Pan-Arctic scale
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-19)While numerous regional studies of bathymetric zonation of benthic fauna globally have been done, few large-scale analyses exist, and no ocean-scale studies have focused on the Arctic Ocean to date. In the present work we, hence, examined bathymetric zonation of macro- and megabenthos over a depth range spanning from the shelf to the abyssal plain (14 – 5416 m) and regionally extending from the Fram ... -
A review of open top chamber (OTC) performance across the ITEX Network
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-19)Open top chambers (OTCs) were adopted as the recommended warming mechanism by the International Tundra Experiment (ITEX) network in the early 1990’s. Since then, OTCs have been deployed across the globe. Hundreds of papers have reported the impacts of OTCs on the abiotic environment and the biota. Here we review the impacts of the OTC on the physical environment, with comments on the appropriateness ... -
Testing the Astolfo Effect on newly-released servants in Fate/Grand Order
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022)Back in 2021, we wrote an article defining the Astolfo Effect. That is what happens when a pop culture representation of a character (fictional or otherwise) becomes more popular than the original. We named it after Astolfo, one of Charlemagne’s paladins and arguably an obscure character in the works that make up the Matter of France and in later literature related to it (such as Orlando ... -
