To protect ecosystems, it is important to understand how environmental disturbances, such as forest fires or hurricanes, affect nature. A study by Eawag and the University of Zurich now shows how their frequency and intensity affect small and large organisms. Accordingly, large species are more affected by disturbances than small species, and this influences the size distribution within ecological communities.
