  • Berg, Torill (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    As in humans, young, female, spontaneously hypertensive rats (SHR) have a lower blood pressure than male SHR. In male, normotensive rats (WKY), α2- and β1+2-adrenoceptors (AR) reciprocally controlled catecholamine release ...
  • Eie, Martin Malmkvist (Master thesis / Masteroppgave, 2017)
    Water is a unique substance and a vital part of life. Today, freshwater ecosystems are considered as one of the most vulnerable ecosystems on Earth. Degradation of lakes and rivers caused by water pollution, climate change, ...
  • Trunk, Thomas; Salah Khalil, Hawzeen; Leo, Jack Christopher (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Many bacteria, both environmental and pathogenic, exhibit the property of autoaggregation. In autoaggregation (sometimes also called autoagglutination or flocculation), bacteria of the same type form multicellular clumps ...
  • Wang, Nelson (Doctoral thesis / Doktoravhandling, 2019)
    Friend or foe? Bacteria are often recognized for causing illness and fatal diseases, but many bacteria are harmless and can even serve beneficial roles in their hosts. In this doctoral work, Nelson Wang investigated both ...
  • Gundersen, Cathrine Brecke; Andersen, Tom; Lindahl, Sofia; Linke, Dirk; Vogt, Rolf David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    Currently the most promising method for capturing anthropogenic produced carbon dioxide (CO2) from suitable point sources is the technique using amines in Post-combustion CO2 Capture (PCC). However, the use of amine is ...
  • Sahlmann, Andrea Silke; Wolf, Raoul; Holth, Tor Fredrik; Titelman, Josefin; Hylland, Ketil (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Anthropogenic pollutants produce oxidative stress in marine organisms, directly or following generation of reactive oxygen species (ROS), potentially resulting in increased accumulation of DNA strand breaks quantified. The ...
  • Matschiner, Michael; Musilová, Zuzana; Barth, Julia Maria Isis; Starostová, Zuzana; Salzburger, Walter; Steel, Mike; Bouckaert, Remco (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Divergence-time estimation based on molecular phylogenies and the fossil record has provided insights into fundamental questions of evolutionary biology. In Bayesian node dating, phylogenies are commonly time calibrated ...
  • Riyahi, Sepand; Hammer, Øyvind; Arbabi, Tayebeh; Sánchez, Antonio; Roselaar, Cees S; Aliabadian, Mansour; Sætre, Glenn-Peter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Background The granivorous house sparrow Passer domesticus is thought to have developed its commensal relationship with humans with the rise of agriculture in the Middle East some 10,000 years ago, and to ...
  • Pineiro Fernandez, Laura (Master thesis / Masteroppgave, 2015)
    Beak morphology is an ecologically important trait for birds. Beak size and shape are crucial for adapting to new niches and for optimal utilization of existing food sources. The adaptive potential of a species can be ...
  • Solberg, Ingrid (Doctoral thesis / Doktoravhandling, 2017)
    Sprat Sprattus sprattus is a marine, forage fish of high ecological and economical value. This thesis addresses the ecology and behavior of sprat during overwintering, a phase that is poorly studied in marine pelagic ...
  • Loe, Leif Egil; Hansen, Brage Bremset; Stien, Audun; Albon, Steve D.; Bischof, Richard; Carlsson, Anja M.; Irvine, Justin; Meland, Morten; Rivrud, Inger Maren; Ropstad, Erik; Veiberg, Vebjørn; Mysterud, Atle (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    As global warming advances, there is a growing concern about the impact of extreme weather events on ecosystems. In the Arctic, more frequent unseasonal warm spells and rain-on- snow events in winter cause changes in ...
  • Freitas, Carla; Olsen, Esben Moland; Moland, Even; Ciannelli, Lorenzo; Knutsen, Halvor (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Understanding responses of marine species to temperature variability is essential to predict impacts of future climate change in the oceans. Most ectotherms are expected to adjust their behavior to avoid extreme temperatures ...
  • Diaz Pauli, Beatriz; Sih, Andrew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Change in behaviour is usually the first response to human-induced environmental change and key for determining whether a species adapts to environmental change or becomes maladapted. Thus, understanding the behavioural ...
  • Wilson, Maria; Haga, Jens Ådne Rekkedal; Karlsen, Hans Erik (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Attacks by aquatic predators generate frontal water disturbances characterised by low-frequency gradients in pressure and particle motion. Low-frequency hearing is highly developed in cephalopods. Thus, we examined behavioural ...
  • Fredriksen, Stein; Gabrielsen, Tove M.; Kile, Maia Røst; Sivertsen, Knut (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Benthic algal vegetation was investigated at 10 sites in Isfjorden, Svalbard. Five sites were visited during summer 2010 and five during summer 2012. Both the littoral and sublittoral vegetation were sampled, the littoral ...
  • Hertel, Anne Gabriela; Bischof, Richard; Langval, Ola; Mysterud, Atle; Kindberg, Jonas; Swenson, Jon; Zedrosser, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Obligate herbivores dominate studies of the eff ects of climate change on mammals, however there is limited empirical evidence for how changes in the abundance or quality of plant food aff ect mammalian omnivores. Omnivores ...
  • Li, Xian; Zhao, Shuhe; Yang, Hong; Cong, Dianmin; Zhang, Zhaohua (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Land use and cover change (LUCC) is important for the global biogeochemical cycle and ecosystem. This paper introduced a change detection method based on a bi-band binary mask and an improved fuzzy c-means algorithm to ...
  • Eikeset, Anne Marie; Richter, Andries Peter; Dankel, Dorothy; Dunlop, Erin; Heino, Mikko Petteri; Dieckmann, Ulf; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ...
  • Hellstad, Stine (Master thesis / Masteroppgave, 2015)
