The proposed project is the continuation of CAOS phase I project J. Soil organisms and vegetation play a leading role in soil structure fomiation and thereby regulate soil hydrological processes, At the same time these organisms depend on the soil moisture regime. Including these feedbacks in models may be crucial for obtaining reliable predictions of change in hydrological processes under changing climate or land-use. The main objective of this project is to improve the understanding and quantification of these feedbacks between abiotic and biotic processes, including human influence, at different spatiotemporai scales, tn the light of our achievements of the first phase, we aim at a quantification of temporal variability in the abiotic and biotic processes considering seasonal and management controls on soil structure and biota as well as the translation of soil organism distributions into hydrological functioning of soils by developing coupled species distribution models and hydrological models. Hereto we propose to use the spatial distribution patterns of soil organismsto describe the spatial differences in soil structure and support the parameterization of hydrological models from plot scale to catchment scale. Finally we seek to apply this knowrledge in widening also the temporal scale by starting to consider the effects of these feedbacks on landscape evolution.
