Scientific focus of the Laboratory ECOS

The research of the laboratory ECOS is centred on the organization, functioning and dynamics of terrestrial plant, animal and microbial communities in relation to ecosystem processes. We study spatial and temporal dynamics of natural ecosystems, impact of management and direct and indirect human impacts (e.g. climate change, land-use change, invasion by alien species, atmospheric depositions, etc.), and ecological resilience and restoration. One of our strength is the functional link between above and belowground communities in the production of critical ecosystem services and as indicators of a changing environment. We combine descriptive field studies, manipulative experiments in the field and in the lab, and ecological modelling (correlative and predictive). Model ecosystems are natural and semi-natural man-used sensitive and altered terrestrial ecosystems (peatlands, sylvopastoral and grasslands systems, floodplains).
