Abstract Details

2007, Master of Science, Miami University, Zoology.
The community composition and C:nutrient stoichiometry of phytoplankton communities is widely variable, and the response of the phytoplankton has implications for food web processes. Specifically, it has been predicted that these responses of the phytoplankton will have implications for energy transfer through the food chain. In this study, we addressed the effects of light, nutrients, and grazing on phytoplankton, and the subsequent effects of the phytoplankton response on food chain efficiency. The relative supply of light, nutrients, and planktivory had strong main and interactive effects on phytoplankton community structure and stoichiometry. Both the taxonomic and stoichiometric food quality of the phytoplankton, as well as the community composition of the zooplankton, affected food chain efficiency across three trophic levels. Since zooplankton as well as phytoplankton response to environmental factors affected the food chain efficiency, this highlights the importance of considering the effects of intermediate trophic levels on food web processes.
