The main focus of our research is in facilitative and competitive interactions that take place in wetlands. The main facilitators in boreal wetlands are beavers, which profoundly affect habitat with their ecological engineering. Their way of wetland alteration include changes in hydrology, material flow, and wetland morphology which result in changes in plant and animal diversity and abundance.
The beaver acts as a whole-community facilitator for invertebrate eating waterbirds and benefits e.g. bats and frogs.
A 3D model of a beaver wetland in our research area Evo. The structure of beaver wetlands is very versatile, and creates suitable habitats for several other species.
Competitive interactions in our studies consist mainly on fish-duck relations. In structurally simple boreal waters, the effect of especially perches on ducks can be considerable. This information is essential to take into account when managing wetlands for waterbirds.
