Evolution of age and length at maturation of Alaskan salmon under size-selective harvest
(Peer reviewed; Journal article, 2014-02)Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation. Spawning ... -
The evolution of insular woodiness
(Journal article; Peer reviewed, 2022)Insular woodiness (IW)—the evolutionary transition from herbaceousness toward woodiness on islands—is one of the most iconic features of island floras. Since pioneering work by Darwin and Wallace, a number of drivers of ... -
Evolution of reproduction periods in seasonal environments
(Journal article; Peer reviewed, 2020)Many species are subject to seasonal cycles in resource availability, affecting the timing of their reproduction. Using a stage-structured consumer-resource model in which juvenile development and maturation are resource ... -
Evolution of temperature optimum in Thermotogaceae and the prediction of trait values of uncultured organisms
(Peer reviewed; Journal article, 2011-06-03)Quantitative characterization of the mode and rate of phenotypic evolution is rarely applied to prokaryotes. Here, we present an analysis of temperature optimum (Topt) evolution in the thermophilic family Thermotogaceae, ... -
The evolution of the metazoan Toll receptor family and its expression during protostome development
(Journal article; Peer reviewed, 2021)Background: Toll-like receptors (TLRs) play a crucial role in immunity and development. They contain leucine-rich repeat domains, one transmembrane domain, and one Toll/IL-1 receptor domain. TLRs have been classified into ... -
Evolution of the Pax-Six-Eya-Dach network: the calcisponge case study
(Peer reviewed; Journal article, 2014-06-23)Background: The Pax-Six-Eya-Dach network (PSEDN) is involved in a variety of developmental processes, including well documented roles in determination of sensory organs and morphogenesis in bilaterian animals. Expression ... -
Evolution of vegetation and climate variability on the Tibetan Plateau over the past 1.74 million years
(Journal article; Peer reviewed, 2020)The Tibetan Plateau exerts a major influence on Asian climate, but its long-term environmental history remains largely unknown. We present a detailed record of vegetation and climate changes over the past 1.74 million years ... -
Evolutionary and developmental perspective on annelid eye and nervous system: Insights from Malacoceros fuliginosus
(Doctoral thesis, 2019-11-25)Eye evolution is far from resolved and despite the considerable interest and decades of study, many questions remain on the evolutionary scenarios of eyes and photoreceptor cells. While examining their ultrastructure has ... -
The evolutionary diversity of barnacles, with an updated classification of fossil and living forms
(Journal article; Peer reviewed, 2021)We present a comprehensive revision and synthesis of the higher-level classification of the barnacles (Crustacea: Thecostraca) to the genus level and including both extant and fossils forms. We provide estimates of the ... -
Evolutionary drivers of kype size in atlantic salmon (salmo salar): domestication, age and genetics
(Peer reviewed; Journal article, 2019-04-17)The diversity of reproduction and associated mating patterns in Atlantic salmon (Salmo salar) has long captivated evolutionary biologists. Salmo salar exhibit strategies involving migration, bold mating behaviours and ... -
Evolutionary effects of fishing gear on foraging behavior and life-history traits
(Peer reviewed; Journal article, 2018-11)Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ... -
An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.
(Journal article; Peer reviewed, 2023)Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ... -
Evolutionary expression differences of creatine synthesis-related genes: Implications for skeletal muscle metabolism in fish
(Peer reviewed; Journal article, 2019)The creatine/phosphocreatine system is the principal energy buffer in mammals, but is scarcely documented in fish. We measured the gene expression of major enzymes of this system, glycine amidinotransferase (GATM), ... -
The evolutionary history of the Central Asian steppe-desert taxon Nitraria (Nitrariaceae) as revealed by integration of fossil pollen morphology and molecular data
(Journal article; Peer reviewed, 2023)The transition from a greenhouse to an icehouse world at the Eocene-Oligocene Transition (EOT) coincided with a large decrease of pollen from the steppe-adapted genus Nitraria. This genus, now common along the Mediterranean ... -
Evolutionary history, connectivity and habitat-use of annelids from deep-sea chemosynthesis-based ecosystems, with an emphasis on the Arctic mid-Ocean Ridge and the Nordic Seas
(Doctoral thesis, 2018-03-16)The enigmatic fauna of chemosynthesis-based ecosystems (CBEs), i.e. hydrothermal vents, cold seeps and organic falls, has been the subject of intensive research over the last decades. However, there are still many aspects ... -
Evolutionary Origin and Developmental Relationships of Germline, Gonads, and Embryonic Mesodermal Precursors
(Doctoral thesis, 2023-11-15)Kjønnscellene, oocytter og sædceller, er essensielle celletyper for artsforplantning hos alle seksuelt reproduserende dyr. Differensiering av kjønnsceller kan skje via to ulike mekanismer: arv og induksjon. I denne oppgaven ... -
Evolutionary rescue as a mechanism allowing a clonal grass to adapt to novel climates
(Journal article; Peer reviewed, 2021)Filing gaps in our understanding of species' abilities to adapt to novel climates is a key challenge for predicting future range shifts and biodiversity loss. Key knowledge gaps are related to the potential for evolutionary ... -
Evolutionary responses of Atlantic cod (Gadus morhua) to concurrent fisheries and climate stressors
(Doctoral thesis, 2024-02-08)Evolutionære ændringer i fisk er efterhånden en anderkendt sandhed, især på grund af forskning i fiskeri-induceret evolution siden 1970'erne. Vi ser især disse ændringer påvirke individuelle livshistorier, resulterende i ... -
Evolutionary turnover of mammalian transcription start sites
(Peer reviewed; Journal article, 2006-05-06)Alignments of homologous genomic sequences are widely used to identify functional genetic elements and study their evolution. Most studies tacitly equate homology of functional elements with sequence homology. This assumption ... -
Evolutionary winners are ecological losers among oceanic island plants
(Journal article; Peer reviewed, 2021)Aim Adaptive radiation, in which successful lineages proliferate by exploiting untapped niche space, provides a popular but potentially misleading characterization of evolution on oceanic islands. Here we analyse the ...
