The impact of fish and planktonic invertebrate predation on zooplankton in experimental mesocosms

This thesis focuses on the effect of fish and invertebrate predation on zooplankton in deep reservoir and shallow lakes. Mesocosms were used to evaluate the separated and combined effect of both type of predation. An appropriate mesocosm approach was modified and used in the Římov reservoir. The last part is dedicated to the effects of predation on zooplankton in contemporary changing environment, mesocosm experiment with different temperature and nutrient levels was conducted
