Research and education activities

The Department of Ecosystem Biology is responsible for the Environmental Ecology Bachelor’s programme, the Ecosystem Biology Master’s and Doctoral programmes, and the Hydrology Doctoral programme. Within the Ecosystem Biology programme, students can choose one of five specializations: Ecology, Conservation Biology, Applied Ecology, Hydrobiology and Soil Biology. Our faculty is the only one in the Czech Republic that offers a study programme focused on soil biology in the ecosystem context.

Our research deals with a wide range of questions in applied and fundamental ecology. It covers both terrestrial and aquatic ecosystems and their interactions including catchment–lake approaches, ecology of aquatic and soil organisms, microbial ecology, processes in soil, studies of aquatic and wetland ecosystems disturbed by human activities, and consequences of climate change and exploitation for terrestrial and aquatic biota. 

We combine a wide range of approaches including advanced molecular techniques, short-term laboratory and mesocosm experiments on model organisms, long-term field observations, mathematical modelling and the use of remote sensing in ecology. The department is involved in a number of national and international projects including the Soil and Water Research Infrastructure.

Freshwater Ecology and Hydrobiology

Our research ranges from processes at microscopic scales to whole-lake surveys. We study carbon and nutrient fluxes, aquatic microbial ecology, biotic interactions in aquatic food webs, and community ecology of zooplankton, aquatic insects and fish. Empirical research is complemented by modelling of life histories and community dynamics. We maintain active study sites in man-made reservoirs, acidified headwater lakes and small standing waters across the Czech Republic and in neighbouring countries. 

Ecosystem and Soil Biology

Our research deals with carbon, nitrogen, and phosphorus fluxes and transformations in wetland, forest, and pasture ecosystems with a focus on plant-soil interactions, primary production, C and nutrient transformations in soil and the composition of soil microbial communities. We also use experimental data to detect forest disturbances and their subsequent regeneration using remote sensing.

Conservation Biology

The research focuses on the ecology and management of endangered species, using orchids in terrestrial systems and aquatic insects in freshwaters as model groups.

Landscape Ecology

We deal with main ecosystem processes and spatio-temporal change detection in landscape. Main topics include forest ecosystem disturbances, land use and landscape structure changes in relation to biodiversity, importance of green infrastructure in urban areas, land-use scenario modelling and landscape politics.
