Density-dependent consequences of size-selective induced life-history changes to population fitness in medaka (Oryzias latipes)
Evangelista, Charlotte; Vøllestad, Leif Asbjørn; Diaz Pauli, Beatriz; Edeline, Eric (Journal article; Peer reviewed, 2020)There is an increasing concern about the potential for size-selective harvest to impair population persistence. Yet little is known about the relative contribution of the evolutionary (shifts in life history) and demographic ... -
Ecological ramifications of adaptation to size-selective mortality
Evangelista, Charlotte; Dupeu, Julia; Sandkjenn, Joakim; Pauli, Beatriz Diaz; Herland, Anders; Meriguet, Jacques; Vøllestad, Leif Asbjørn; Edeline, Eric (Journal article; Peer reviewed, 2021)Size-selective mortality due to harvesting is a threat to numerous exploited species, but how it affects the ecosystem remains largely unexplored. Here, we used a pond mesocosm experiment to assess how evolutionary responses ... -
The evolving story of catadromy in the European eel (Anguilla anguilla)
Durif, Caroline; Arts, M.; Bertolini, F.; Cresci, Alessandro; Daverat, F.; Karlsbakk, Egil Erlingsson; Koprivnikar, J.; Moland, Even; Olsen, Esben Moland; Parzanini, C.; Power, M.; Rohtla, Mehis; Skiftesvik, Anne Berit; Thorstad, Eva Bonsak; Vøllestad, Leif Asbjørn; Browman, Howard (Journal article; Peer reviewed, 2023)Anguillid eels were once considered to be the classic example of catadromy. However, alternative life cycles have been reported, including skipping the freshwater phase and habitat shifting between fresh, brackish, and ... -
Stoichiometric consequences of size-selective mortality: An experimental test using the Japanese medaka (Oryzias latipes)
Evangelista, Charlotte; Diaz Pauli, Beatriz; Vøllestad, Leif Asbjørn; Edeline, Eric (Journal article; Peer reviewed, 2020-07-01)The determinants of intraspecific stoichiometric variation remain difficult to elucidate due to their multiple ori- gins (e.g. genetic vs. environmental) and potential interactive effects. We evaluated whether two size-selected ... -
Within-species variation in the gut microbiome of medaka (Oryzias latipes) is driven by the interaction of light intensity and genetic background
Evangelista, Charlotte; Kamenova, Stefaniya; Diaz Pauli, Beatriz; Sandkjenn, Joakim; Vøllestad, Leif Asbjørn; Edeline, Eric; Trosvik, Pål; de Muinck, Eric (Journal article; Peer reviewed, 2023)Unravelling evolution-by-environment interactions on the gut microbiome is particularly relevant considering the unprecedented level of human-driven disruption of the ecological and evolutionary trajectories of species. ...
