Summary
Herbivorous zooplankton have a vital role in aquatic food webs linking phytoplankton primary production and fish. Animals are constantly challenged by multiple environmental stressors, and their combined effect may not be predictable from effects of the stressors individually. The aim of the study is to quantify zooplankton responses to multiple stressors. The effects of food quality, temperature and microplastics on zooplankton survival, growth, reproduction, lipid composition and genetic regulation of metabolism will be studied in laboratory. The model species include the freshwater filter-feeding cladoceran Daphnia magna, widely used in ecological and ecotoxicological studies, and the marine copepod Calanus sp., a key stone species with a vital role in transfer of energy in marine food webs. The study will significantly increase our knowledge on how basic environmental conditions (diet, temperature) interact and affect organisms’ ability to cope with additional stress factors.
