sp10 Stoichiometry



Ecological stoichiometry is a theoretical framework allowing the prediction of competitive and trophic interactions based on the balance between resource supply and resource needs of interacting species. Our subproject will analyze the relationship between plant diversity and the ecological stoichiometry of multiple ecosystem processes and trophic interactions. The stoichiometric information on plants, animals, seeds and pollen we will link to performance measures such as plant productivity, seed predation, flower visitation and pollination success, belowground decomposition, and aboveground herbivory. This enables this us to test the effect of species composition and diversity of plants as well as ecological stoichiometry on mutualistic and trophic plant-animal interactions. Our stoichiometric approach to these interactions thereby unifies the different above- and below-ground approaches in the different subprojects on interspecific interactions as well as the ecosystem approach to element cycling.
