I have mainly worked with colonization-extinction dynamics, dispersal and persistence of sessile species (e.g. lichens, mosses, fungi and vascular plants), but lately I have gained an increased interest in pollinators. Right now, I work a lot with population dynamics of butterflies in relation to grazing and extreme weather. I work 50% at Linköping University and 50% at Calluna AB.
Victor Johansson
Associate Professor, Docent
I develop population models that can be used to simulate future population persistence under different scenarios of management and climate change.
Presentation
I have a general interest in landscape and (meta)population ecology, and its applications for conservation.
