(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)The primate vertebral column has been extensively studied, with a particular focus on hominoid primates and the last common ancestor of humans and chimpanzees. The number of vertebrae in hominoids—up to and including the ...

Evolution, Expression Patterns, and Distribution of Novel Ribbon Worm Predatory and Defensive Toxins (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Ribbon worms are active predators that use an eversible proboscis to inject venom into their prey and defend themselves with toxic epidermal secretions. Previous work on nemertean venom has largely focused on just a few ...

An evolutionarily conserved glycine-tyrosine motif forms a folding core in outer membrane proteins (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)An intimate interaction between a pair of amino acids, a tyrosine and glycine on neighboring β-strands, has been previously reported to be important for the structural stability of autotransporters. Here, we show that the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)An evolutionarily stable strategy (ESS) is an evolutionary strategy that, if adapted by a population, cannot be invaded by any deviating (mutant) strategy. The concept of ESS has been extensively studied and widely applied ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Saxitoxin and its derivatives are potent neurotoxins produced by several cyanobacteria and dinoflagellate species. SxtA is the initial enzyme in the biosynthesis of saxitoxin. The dinoflagellate full mRNA and partial genomic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The typically repetitive nature of the sex-limited chromosome means that it is often excluded from or poorly covered in genome assemblies, hindering studies of evolutionary and population genomic processes in non-recombining ...
-
(Doctoral thesis / Doktoravhandling, 2016)Teleosts comprise a very diverse group of species where genome sequencing the last decade has revealed great variability regarding their genetic basis for immunity. With emphasis on the innate immune system, this thesis ...
-
(Doctoral thesis / Doktoravhandling, 2022)The vast diversity of species we encounter in nature has always fascinated scientists, thus the evolutionary processes responsible for the origin of new species (speciation) is a topic of constant interest among biologists. ...
-
(Master thesis / Masteroppgave, 2015)Hybridization is increasingly recognized as a source of novel variation, but how hybridization can contribute to evolution is still not fully understood. Insights into the evolutionary potential of hybrid species, and the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Current evolutionary psychological (EP) perspectives on filicide perpetration propose that it is an extreme behavioral manifestation of psychological mechanisms that evolved due to their function toward enabling ancestrally ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Haptophytes are photosynthetic protists found in both freshwater and marine environments with an origin possibly dating back to the Neoproterozoic era. The most recent molecular phylogeny reveals several haptophyte “mystery ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Genome sequencing of the teleost Atlantic cod demonstrated loss of the Major Histocompatibility Complex (MHC) class II, an extreme gene expansion of MHC class I and gene expansions and losses in the innate pattern recognition ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Yersinia pestis is transmitted from fleas to rodents when the bacterium develops an extensive biofilm in the foregut of a flea, starving it into a feeding frenzy, or, alternatively, during a brief period directly after ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)For over 50 years, the great tit (Parus major) has been a model species for research in evolutionary, ecological and behavioural research; in particular, learning and cognition have been intensively studied. Here, to provide ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)A major challenge in evolutionary biology is understanding how stochastic and deterministic factors interact and influence macroevolutionary dynamics in natural populations. One classical approach is to record frequency ...
-
(Book / Bok / PublishedVersion; Peer reviewed, 2023)Essays on evolvability from the perspectives of quantitative and population genetics, evolutionary developmental biology, systems biology, macroevolution, and the philosophy of science. Evolvability—the capability of ...
-
(Doctoral thesis / Doktoravhandling, 2020)Research in evolutionary biology is driven by curiosity about the evolution of complex organisms. Their origin and maintenance depend on two conflicting properties ‐ evolvability and robustness. Evolvability is the ability ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Understanding the causes and limits of population divergence in phenotypic traits is a fundamental aim of evolutionary biology, with the potential to yield predictions of adaptation to environmental change. Reciprocal ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The concept of evolvability—the capacity of a population to produce and maintain evolutionarily relevant variation—has become increasingly prominent in evolutionary biology. Paleontology has a long history ...
