My current research can be put under the label ‘global change biogeography’. Most of my research focuses on the causes and consequences of environmental change at different spatial (from sites to continents) and temporal (from seasons to millennia) scales. I try to decipher environmental change mostly through the lens of variation in biological diversity in aquatic and terrestrial systems, which has a lot to do with my life-long interest in animals and plants. Along with both national and foreign collaborators, I have recently become interested in a more comprehensive framework incorporating both biotic and abiotic features of nature. As almost all areas across the world are affected by anthropogenic impacts, I am also currently devising a refined general framework that incorporates biotic, abiotic and human-altered features of drainage basins. At the level of a drainage basin, different phenomena are acting simultaneously and should be considered in monitoring, management, restoration and conservation of nature and ecosystem services. Finally, having been more like a hobby so far, I am also interested in earth history and how historical changes are associated with the development of civilizations and livelihoods of people today.
