Trophic carbon transfer efficiency under carbon dioxide stress

Cel

Current models on future climate change predict a twofold increase in atmospheric CO2 and associated decrease in oceanic pH by about 0.4 units until the end of present century. How this drastic change will affect marine ecosystem dynamics and food webs in the coastal ocean is unforeseen. Increasing evidence suggest that phytoplankton, which is at the base of the marine food web, is affected at various levels cell physiology, elemental composition and community structure - by the alteration of dissolved CO2 concentrations. Therefore, present interactions between phytoplankton and zooplankton can be altered with the consequence of a significantly reduced trophic transfer efficiency and subsequent secondary production. We propose to study the effects of a CO2/pH change on phytoplankton biochemical composition and concurrent effects of potentially altered food quality on secondary producers in the marine system. Three major issues will be addresses in separate controlled experiments by using relevant and natural co-occurring species: 1. the change in the biochemical composition of essential nutrients in algae, 2. the consequence for growth and reproductive success and 3. the effects of increased carbohydrate excretion on zooplankton feeding behavior. The proposed research will not only benefit the excellence of science in the EU by establishing a new field of research in zooplankton ecology, but also foster the career of the researcher by the extending his knowledge by learning of new state-of-the-art techniques in lipid chemistry and by the achievement of complementary skills.
