Cumulative impacts of local and global environmental changes in freshwater food webs


Understanding and forecasting the impact of global change on ecosystems is one of the great challenges for contemporary ecology. Shifts in mean and variation of temperature, CO2 concentration or other factors percolate through a network of food web interactions and may alter the nature and magnitude of local ecological processes. I will discuss experimental and observational work aimed at understanding how shifts in temperature and variability on different time scales alter diversity and the importance of top-down and bottom-up factors in freshwater ecosystems.
