Ecological stoichiometry

Ecological stoichiometry considers how the balance of energy and elements affects and is affected by organisms and their interactions in ecosystems. Changes in elemental ratios at one level of an ecosystem can have cascading affects on other ecosystems components as well as on biogeochemical cycling. As recent work suggests, ocean warming, acidification and deoxygenation can all instigate stoichiometric changes in organisms, nutrient pools and the fluxes between them. How these changes balance out in multi-trophic communities and whether or not they lead to changes in nutrient reservoirs and carbon sequestration is the focus of on-going research in our division.
