Each student will search the literature for information about one of the important nutrient fluxes in a mangrove ecosystem. I have assigned your flux, see the list below. Each student will make a short (10 minute) presentation to the class on their flux, and we will use the information to try to assess the relative importance of the fluxes. Each of you will explain your process, discussing not just products and reactants and the magnitude of the flux, but also for what purpose the reaction is done. Present all of your fluxes in units of umoles m^-2d^-1, or umoles g^-1d^-1. If you can not find mangrove-specific estimates of rates, use estimate from other systems and extrapolate to mangroves. Bring any presentation materials you need on overhead transparencies.
