(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Building the Tree of Life (ToL) is a major challenge of modern biology, requiring advances in cyberinfrastructure, data collection, theory, and more. Here, we argue that phylogenomics stands to benefit by embracing the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The factors that drive the emergence of vector-borne diseases are difficult to identify due to the complexity of the pathogen-vector-host triad. We used a novel comparative approach to analyse four long-term datasets ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Persistent organic pollutants (POPs), including brominated flame retardants (BFRs), perfluoroalkyl substances (PFAS) and metals, can accumulate in marine mammals and be transferred to offspring. In this study, we analyzed ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Organisms need to constantly inform their cellular machinery about the biochemical and physical status of their surroundings to adapt and thrive. While some external signals are also sensed intracellularly, a considerable ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The diatom Pseudo-nitzschia H. Peragallo is perhaps the most intensively researched genus of marine pennate diatoms, with respect to species diversity, life history strategies, toxigenicity, and biogeographical distribution. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Los lagartos dependen principalmente de señales químicas y visuales para comunicarse y, en menor medida, de señales acústicas, por lo que en general se ha considerado que estos reptiles no emiten sonidos. Sin embargo, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Strength of species interaction may have profound effects on population dynamics. Empirical estimates of interaction strength is often based on the assumption that the interaction strengths are constant. Barents Sea cod ...
-
(Master thesis / Masteroppgave, 2021)Karpefisken karuss (Carassius carassius) har en unik evne til å tolerere svært lave oksygennivåer, og kan leve i helt anoksiske tilstander over flere måneder under isdekke. Dens unike egenskaper innebærer en svært høy ...
-
(Master thesis / Masteroppgave, 2019)Bentiske alger og ålegras utgjør to viktige marine habitater langs Norges kystlinje. Bentiske diatomeer som epifytter er ofte funnet på disse. Det er ingen tidligere studier fra tempererte områder av sesongmessig variasjon ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Defined conjugation of functional molecules to block copolymer end groups is a powerful strategy to enhance the scope of micellar carriers for drug delivery. In this study, an approach to access well-defined polycarbonate-based ...
