What spurs me on is the question what determines the diversity, composition, functioning and adaptation of soil fauna communities. I am especially interested in the interplay between species-specific traits and spatial scales in determining shifts in community composition under environmental stress. I study which functional traits underlay changes in species composition, from the micro-scale (m2) to the macro-scale (among biomes). I also study how changes in species composition (via response traits) affect important soil processes (via effect traits), such as litter decomposition.
My aim is to integrate ecological and evolutionary concepts into community ecology by using inter- and intraspecific variation in species traits, including tolerance traits (micro-scale) and dispersal traits (meta- to macro-scale), to understand the impact of environmental changes on local community composition and functioning. I am especially interested how adaptation in life history traits of ecosystem engineers impact ecosystem dynamics.
My research emphasizes a mechanistic approach, linking species functional traits to community composition and ecosystem functioning. I use a variety of study systems, including green beach, salt marsh, moist grasslands, savanna and sub-arctic tundra, as well as a variety of model organisms, including ecosystem engineers such as bioturbating earthworms, landhoppers and termites, and detritivores like Collembola and terrestrial Isopoda.
