Research and collaboration

We have four main study systems: the Colorado potato beetle (Leptinotarsa decemlineata) offers us a unique opportunity to study invasion genetics, on both neutral and adaptive level (resistance genes, life-history traits) on the invading populations. We are also interested in identifying the intraspecies differences in physiological traits across latitudinal gradients and their adaptive significance in defining the geographic range of L. decemlineata. Whiteflies (Trialeurodes vaporariorum) has established populations in the greenhouses and thus this project focuses on determining the spatial and genetic population structure of this invasive phytophagous insect pest as well as trying to understand whether it can become naturalised in Finland. Lupine (Lupinus polyphyllus) is already an established invader, and this allows us to study its effects on native flora and fauna. Bacterial microcosms on the other hand allows us to study evolutionary responses of invasions.
