My research focuses on the natural and anthropogenic factors that regulate biodiversity and ecosystem functioning in freshwater ecosystems, and influence connectivity between aquatic and terrestrial habitats.


I work at the interface between community and ecosystem ecology, with a strong focus on how biotic (e.g. biodiversity, keystone species) and abiotic (e.g. nutrients, temperature) affect ecosystem functioning.  Most of my research has focused on stream and river networks, though I increasingly work in lakes and riparian habitats also.  Streams, lakes and their associated riparian habitats underpin landscape integrity, transport nutrients, moderate high and low flows, and supporting life by supplying fresh water. However, these ecosystems are heavily impacted by multiple stressors, such as elevated organic and inorganic pollution, hydromorphological modification, sedimentation, and invasive species. I investigate how these stressors interact with natural sources of environmental variability to affect biodiversity of different organism groups (especially benthic macroinvertebrates, but also aquatic fungi, diatoms, and macrophytes), and key ecosystem processes, including the biomass accrual of algae, and decomposition of terrestrial detritus.  My research is conducted in both the field and laboratory, and also exploits existing data. Key areas of interest include:

• The importance of biodiversity for maintaining ecosystem functioning in both stream and terrestrial environments

• Cross-ecosystem subsidies, from the terrestrial environment into streams, and vice-versa

• Effects of multiple stressors on stream community composition and ecosystem functioning, and interactions of biodiversity change with different types of abiotic stressor

• Impacts of invasive species on ecosystem functioning

• River restoration

• General stream ecology, with a focus on food webs and especially detrital pathways

 I am the Director of Post-graduate studies at the Department of Aquatic Sciences & Assessment, and also the department's contact person for questions about aquatic invasive species in Sweden
