Jana Růžičková

*22 December 1989, Valašské Meziříčí, Czech Republic

I am a researcher in the Integrative Ecology Research Group of the Hungarian Research Network (HUN-REN), hosted by the Eötvös Loránd University (ELTE) and the Hungarian Natural History Museum (MTM), Budapest, Hungary. I am particularly interested in ecology of ground beetles (Coleoptera: Carabidae). I've been working on radio telemetry, habitat use and movement patterns of selected large species as well as community ecology of carabids in managed temperate forests, agricultural landscapes and post-mining areas in Central Europe.

Currently, I explore how the different management practices of two silvicultural systems, represented by rotation forestry (clear-cuts, preparation cuts, retention tree group) and continuous cover forestry (gap-cutting), can affect ground beetles at different levels of the organization, from assemblages and species populations to individuals and their behavior.
