Can bryophyte groups increase functional resolution in tundra ecosystems?
(Journal article; Peer reviewed, 2021)The relative contribution of bryophytes to plant diversity, primary productivity, and ecosystem functioning increases towards colder climates. Bryophytes respond to environmental changes at the species level, but because ... -
Can catch data from small meshed gears in shallow waters be used to estimate recruitment indices of Norwegian coastal cod, Northeast Arctic saithe and pollack along the Norwegian coast?
(Master thesis, 2019-06-21)Shallow waters (<30 meters) are important nursery areas for coastal cod, saithe and pollack, before they recruit to their respective fisheries at an age around 3 years old. Still, no study provides information on fish ... -
Can enrichment improve the post-release survival of hatchery-reared Atlantic salmon fry (Salmo salar)? – A field experiment
(Master thesis, 2018-06-26)Release of captive-reared fish to supplement reduced, wild populations has become a common tool for conservation and management. Such attempted population enhancements have, however, had limited success, and several previous ... -
Can environmental toxins increase parasite fitness? Ecotoxicological studies on the effects of microcystin on the host-parasite dynamics of Schistocephalus solidus
(Master thesis, 2020-08-21)Background: Eutrophication of aquatic biomes and exacerbated climate change effects are expected to result in a global increase in harmful cyanobacterial blooms. Cyanotoxins are detrimental to animal health, but how they ... -
Can fresh water diets influence recovery in Atlantic salmon post-smolts after SAV3 challenge in sea water?
(Master thesis, 2020-07-08)Pankreas sykdom (PD) forårsaket av salmonid alfavirus (SAV) er en betydelig utfordring i norsk oppdrettsnæring. Å undersøke om forskjeller i fôrsammensetning før overføring til sjøvann kan påvirke sykdommens progresjon og ... -
Can less be more? Effects of reduced frequency of surveys and stock assessments
(Peer reviewed; Journal article, 2016)Uncertain and inaccurate estimates are a prevailing problem in stock assessment, despite increasingly sophisticated estimation methods and substantial usage of scientific and financial resources. Annual scientific surveys ... -
Can magnetotail reconnection produce the auroral intensities observed in the conjugate ionosphere?
(Peer reviewed; Journal article, 2009-06)[1] In a recent case study, Borg et al. (2007) reported that an inverted V structure, caused by a field-aligned potential drop of 30 kV producing very strong X-ray aurora, was found in connection with tail reconnection. ... -
Can Romeo and Juliet meet? Or rendezvous games with adversaries on graphs
(Journal article; Peer reviewed, 2023)We introduce the rendezvous game with adversaries. In this game, two players, Facilitator and Divider, play against each other on a graph. Facilitator has two agents and Divider has a team of k agents located in some ... -
Can snow depth be used to predict the distribution of the high Arctic aphid Acyrthosiphon svalbardicum (Hemiptera: Aphididae) on Spitsbergen?
(Peer reviewed; Journal article, 2011-10-13)Background: The Svalbard endemic aphid Acyrthosiphon svalbardicum (Heikinheimo, 1968) is host specific to Dryas octopetala L. ssp octopetala (Rosaceae). It has been hypothesized that the aphid is present on those areas ... -
Can we use ice sheet reconstructions to constrain meltwater for deglacial simulations?
(Peer reviewed; Journal article, 2012)Freshwater pulses from melting ice sheets are thought to be important for driving deglacial climate variability. This study investigates challenges in simulating and understanding deglacial climate evolution within this ... -
Cancellation of the precessional cycle in δ18O records during the Early Pleistocene
(Journal article; Peer reviewed, 2021)The dominant pacing of glacial‐interglacial cycles in deep‐ocean δ18O records changed substantially during the Mid‐Pleistocene Transition. The precessional cycle (∼23 ky) is absent during the Early Pleistocene, which we ... -
“Candidatus Ethanoperedens,” a thermophilic genus of archaea mediating the anaerobic oxidation of ethane
(Journal article; Peer reviewed, 2020)Cold seeps and hydrothermal vents deliver large amounts of methane and other gaseous alkanes into marine surface sediments. Consortia of archaea and partner bacteria thrive on the oxidation of these alkanes and its coupling ... -
"Candidatus Subterrananammoxibiaceae," a New Anammox Bacterial Family in Globally Distributed Marine and Terrestrial Subsurfaces
(Journal article; Peer reviewed, 2023)Bacteria specialized in anaerobic ammonium oxidation (anammox) are widespread in many anoxic habitats and form an important functional guild in the global nitrogen cycle by consuming bio-available nitrogen for energy rather ... -
Captive breeding of European freshwater mussels as aconservation tool: A review
(Journal article; Peer reviewed, 2023)1. Freshwater mussels are declining throughout their range. Their importantecological functions along with insufficient levels of natural recruitment haveprompted captive breeding for population augmentation and questions ... -
Capturing big fisheries data: Integrating fishers’ knowledge in a web-based decision support tool
(Journal article; Peer reviewed, 2022-12-12)There is increasing interest in utilizing fishers’ knowledge to better understand the marine environment, given the spatial extent and temporal resolution of fishing vessel operations. Furthermore, fishers’ knowledge is ... -
Capturing the coupled hydro-mechanical processes occurring during CO2 injection – example from In Salah
(Peer reviewed; Journal article, 2014)At In Salah, CO2 is removed from the production stream of several natural gas fields and re-injected into a deep and relatively thin saline formation, in three different locations. The observed deformation on the surface ... -
Carbohydrate metabolism during vertebrate appendage regeneration: What is its role? How is it regulated? A postulation that regenerating vertebrate appendages facilitate glycolytic and pentose phosphate pathways to fuel macromolecule biosynthesis
(Peer reviewed; Journal article, 2014-01)We recently examined gene expression during Xenopus tadpole tail appendage regeneration and found that carbohydrate regulatory genes were dramatically altered during the regeneration process. In this essay, we speculate ... -
