Assoc. Prof. Dr. Petr Znachor is a distinguished limnologist and hydrobiologist whose research focuses on phytoplankton ecology, reservoir limnology, and the biogeochemical cycling of methane in aquatic systems. His work integrates field studies, long-term ecological data, and advanced time-series analyses to understand how climate change, weather extremes, and anthropogenic pressures influence the functioning and water quality of lentic ecosystems. He has led and contributed to numerous national and international research projects addressing the ecological dynamics of plankton communities and the development of biomanipulation techniques to improve water quality in reservoirs. His expertise spans a wide range of topics, including diatom ecophysiology, microbial interactions, fluorescence-based methods, and the spatial-temporal variability of phytoplankton. As an accomplished researcher and academic, he has published extensively in high-impact international journals and has made significant contributions to the advancement of freshwater ecology. His scientific leadership is reflected in his roles within the Institute of Hydrobiology of the Biology Centre of the Czech Academy of Sciences and in professional societies such as the Czech Limnological Society and the Czech Long-Term Ecological Research network. With a strong interdisciplinary approach, Dr. Znachor’s research continues to enhance understanding of freshwater ecosystem responses to environmental change and to inform sustainable water management strategies.
