Description
Christian Giardina presents on ecosystem carbon fluxes and storage and discusses how and why these vary across ecosystems. He includes a great primer on photosynthesis, respiration and senescence (conversion of living biomass to dead biomass). Variables that regulate carbon fluxes and storage include precipitation, temperature, seasonality, species, soil, hydrology and site history. Different ecosystems vary greatly in terms of how carbon moves through them, and several examples are presented including northern hardwood forests, tropical plantations, subalpine conifer forests and subtropical montane rainforests.
