Present project (2013-present)
An experimental evaluation of fisheries-induced evolution and its consequences
PI: Mikko Heino
Exploited stocks are experiencing phenotypic change in life history traits; mainly in age and size at maturation, growth, and fecundity. These observed changes occur in the expected direction if fishing would be causing evolutionary change, referred to as fisheries-induced evolution (FIE).
However, it is still not clear whether the changes observed have a genetic basis, whether fishing selectivity is the main driver, and whether the changes are occurring at a fast enough pace to be considered in fisheries management plans.
We try to clarify some of these questions using an experimental approach with guppies, Poecila reticulata, as model species. Our harvesting experiment consists on nine experimental populations subjected to different size-selective mortalities since October 2010. Our data combines samples of phenotypic data and genetic data from common garden and molecular analyses. We are mainly interested in studying how life histories are shaped by different fishing regimes, but we also study behaviour, morphology, brain and cognition.

PhD project (2008-2012)
Contemporary evolution caused by fisheries. Contributions from experimental studies
Supervisors: Mikko Heino, Anne Christine Utne Palm and David Reznick
Besides establishing the large-scale harvesting experiment, for my PhD project we performed smaller experiments to study other aspects related to fishing effects. We studied which factors other than fishing can affect maturation schedules, estimating Probabilistic Maturation Reaction Norms (PMRNs) from guppies reared in laboratory conditions. We mainly focused of the effect of growth rate, social environment and the maturation stage on the shape of PMRNs.
We investigated how different fishing gears (experimental trap and trawl) are selective towards different behavioural personality traits (boldness, activity), and how these are related to production traits (somatic growth).
In addition, we developed the “candy experiment”, which is a savoury approach to disseminate the ecological and evolutionary consequences of fishing to schools or undergraduate students.

Other projects (2006-2008)
Prior to my PhD I studied how different aspects of human activities affected reproductive strategies and sexual selection. Particularly, I studied with Outi Ala-Honkola and Kai Lindström how male reproductive behaviour is affected by inbreeding depression in the least killifish, Heterandria formosa. Moreover, I studied how eutrophication affects parental care (in collaboration with Marja Jarvenpää and Kai Lindström) and how social environment affects female choice in the sand goby, Pomatoschistus minutus.
