From 1^st November 2016, I will be part of CEES as a postdoctoral fellow in the project “Productivity and Resilience Enhancement of Exploited Fish stocks: an experimental approach”. We will be studying how different size-selective fishing regimes affect the stability of exploited populations and their trophic cascades using experimental populations of medaka fish. During the first year I will be based at the Pierre et Marie Curie University in Paris. Once the experimental part of the project is over I will move to Oslo. The project is a collaboration between CEES (Vøllestad), NMBU and French researcher.

I am interested in the anthropogenic causes of contemporary evolution. I studied fisheries-induced evolution during my PhD and postdoctoral position at the University of Bergen developing selection lines in guppies. Former projects involved studying the effect of eutrophication and inbreeding due to habitat destruction on mating and parental care behaviour in the sand goby and the least killifish at Åbo Akademi and at the University of Helsinki, respectively.

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 lines of medaka (Oryzias latipes) with contrasted life-history strategies (small- and large-breeder lines with slow growth and early maturity vs. fast growth and late maturity) differed in their organismal stoichiometry (percentage and ratios of carbon [C], nitrogen [N] and phosphorus [P]) in a mesocosm experiment. We also tested how size-selection interacted with environmental conditions (i.e. two levels of fish density and light intensity), body condition and sex. Results showed that large-breeder fish were significantly N-enriched compared to small-breeders, while the two size-selected lines did not differ in body P composition. Size-selection interacted with density – high density only affected small-breeders leading to decreasing %C and C: N – and with sex – large-breeder females had higher %C and C:N values than large-breeder males. Finally, C:P and N:P ratios in- creased with body condition due to decreasing %P. Overall, our results show that the ecological consequences of size-selective mortality extend to organismal stoichiometry and may, from there, change nutrient cycling and ecosystem functioning.
