The identification of the roles and functions of specific groups of organisms is a key to understanding the importance of biodiversity to ecosystem functioning. I focused on the biodiversity, distribution, composition and abundance of pelagic bacteria, protists, aquatic fungi, zooplankton and fish in 75 unpolluted, relatively large lakes of southern Scandinavia. This study is the first to cover an extensive longitudinal gradient (750 km) on a set of boreal lakes carefully selected to be as similar as possible with respect to factors other than local productivity and spatial position. I applied both DNA-metabarcoding (454 and illumina sequencing) and non-molecular methods to explore community ecology and distribution patterns of biota across trophic levels, and related the data to the measured spatial factors and local environment through statistical analyses in R using community ecology data packages.
My research interests are in the fields of microbial ecology, microbiology, mycology, biogeography, molecular ecology, bioinformatics and statistics.
