Abstract:Nitrogen (N) cycle in ecosystems has been overbalanced by human activities. However, it remains uncertain whether the altered N supply results in a change in the elemental composition of phytoplankton and, consequently, affects the life history strategy of zooplankton. To investigate these impacts, a simple lab-based food chain was established. Results show that lack or excess of nitrogen reduced algal density, cell volume, growth rate and chlorophyll content. Moreover, N content in algae significantly increas… Show more
