Thomsen embedded in a drift-algal mat composed of the highly invasive Gracilaria vermiculophylla. G. vermiculophylla has invaded numerous European countries and both the east and west coast of the US.
Thomsen conducting biomechanical breakage tests on Ecklonia radiata, a dominant kelp in Australasia. Such data are used to predict kelp survival during storms.
Gracilaria attached to a tagged and partly buried Battilaria australis. This gastropod is ubiquities in Swan estuary ( Australia) providing amble substratum for fixed populations of Gracilaria and its associated epibiota. Analogue biogenic mini-reefs are studied in the US, Denmark and New Zealand.

I am a coastal ecologist that primarily have studied plant and animal communities on and around temperate reefs, including stone reefs in Denmark, oysters and polychaete reefs in USA, limestone reefs in Australia and bivalve reefs in New Zealand. My research focuses, to a large extent, on how anthropogenic stressors, such as introduction of non-native species, eutrophication, enhanced sedimentation, and global warming, impact structure and productivity of marine communities, and I use manipulative experiments to test how patterns in biological communities are generated and maintained.
I am particularly interested in facilitation processes that increasingly are found to influence marine community structure, and therefore should be included in coastal management and conservation. This research provides predictions on how coastal habitats will respond to anthropogenic stressors and recommendations for conservation strategies needed to ameliorate their impacts. Above topics are studied with collaborators at field sites in Denmark, USA, Western Australia and New Zealand.
