| Description | In 2014 a large mesocosm experiment studying the effect of warming on shallow lakes will be initiated at the NIOO-KNAW in Wageningen. One of the things that will be looked into is the effect of warming on the nutrient fluxes in shallow lakes. Warming may alter nutrient fluxes in various ways. It is, for instance, well known that warming enhances sediment nutrient release. How strong this enhancement is, depends on the oxygen conditions and the sediment composition and differs for phosphorus and nitrogen. Changes in nutrient fluxes alters the nutrient availability for phytoplankton and hence may alter which nutrient is limiting for phytoplankton growth.
This research subject deals with (1) the alteration of nutrient fluxes from the sediment to the water column and (2) bioassays to determine which nutrient is limiting phytoplankton growth. It thus encompas biogeochemical work measurements and biological work. You will form part of a divers research team working together in the mesocosms on topics varying from greenhouse gas balances, phytoplankton composition and stoichiometry (very much linked to the research topic advertised here). Joining the team will thus provide you the opportunity to learn many different techniques and enhance your knowledge regarding a wide variety of “hot” research topics. The experiments will partially take place in Wageningen at the NIOO-KNAW and you should therefore be willing to commute. |
