Evolution of the Pax-Six-Eya-Dach network: The calcisponge case study
(Journal article; Peer reviewed, 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 tropical land temperature across the last glacial termination
(Journal article; Peer reviewed, 2022)The tropical West Pacific hosts the warmest part of the surface ocean and has a considerable impact on the global climate system. Reconstructions of past temperature in this region can elucidate climate connections between ... -
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 ... -
Evolutionarily conserved aspects of animal nutrient uptake and transport in sea anemone vitellogenesis
(Journal article; Peer reviewed, 2022)The emergence of systemic nutrient transport was a key challenge during animal evolution, yet it is poorly understood. Circulatory systems distribute nutrients in many bilaterians (e.g., vertebrates and arthropods) but are ... -
Evolutionary and behavioral analysis of neuropeptides in bilaterians
(Doctoral thesis, 2017-06-29)Neuropeptides are a diverse group of neurosecretory signaling molecules that are utilized by the nervous system of all bilaterian animals. These signaling molecules are involved in most physiological processes and can play ... -
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 epigenetics approach to schizophrenia
(Doctoral thesis, 2018-09-28)Schizophrenia is a psychotic disorder with an estimated lifetime prevalence of ~1% worldwide. Despite reduced fecundity of patients, this rate is stable across population groups separated by geography and time. There is ... -
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 Implications of the microRNA- and piRNA Complement of Lepidodermella squamata (Gastrotricha)
(Journal article; Peer reviewed, 2019-02-22)Gastrotrichs—’hairy bellies’—are microscopic free-living animals inhabiting marine and freshwater habitats. Based on morphological and early molecular analyses, gastrotrichs were placed close to nematodes, but recent ... -
Evolutionary inference across eukaryotes identifies universal features shaping organelle gene retention
(Journal article; Peer reviewed, 2022)Mitochondria and plastids power complex life. Why some genes and not others are retained in their organelle DNA (oDNA) genomes remains a debated question. Here, we attempt to identify the properties of genes and associated ... -
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 ...
