Working with

My research focus on how nature chenges over time where processes generated by humans (e.g., climate change, forestry, agiculture…) work on concert with natural fluctuations. I use the insect group Odonata as model organism and study species numbers and abundance in various water bodies/landscapes.

One current project involves questions linked to how species composition/species assembly is affected by acidification, temperature change and prownification in lakes and wetlands in southern and central Sweden. Tha aim is to gain a better understanding on the colonization processes of species in different environments and what reavers are important for (re)colonization and exlocal extinction. A similar project is ongoing in southern Brazil where I, together with local scientists, study species composition and survival of species in Brazinial pampa grasslands.

A second project will look into how extremely northern species are adapted to the rapid transitions between summer and winter. There may be a genetic predisposition/adaptation to such rapid changes which would give the species better possibilities to survive ongoing climate change. This project is a collaboration with American scientists.

I am a member of the Swedish expert committee for red listing of aquatic invertebrates and active in the red listing of Odonata on an EU and global level.

Key words: Odonata, dragonflies, species communities, species assemblies, climate change, species turnover
