Summary:
IN SEMIARID ECOSYSTEMS, THE TRANSFER OF WATER, SEDIMENTS, AND NUTRIENTS FROM BARE (SOURCE AREAS) TO VEGETATED PATCHES (SINK AREAS) IS KNOWN TO BE CRUCIAL FOR THE ECOSYSTEM FUNCTIONING AND MAINTENANCE OF VEGETATION PATCHES. BECAUSE OF THIS IMPORTANCE OF SOURCE-SINK DYNAMICS TO THE FUNCTIONING OF SEMIARID ECOSYSTEMS, THE KNOWLEDGE OF THEIR CONTROL FACTORS, PARTICULARLY THE ROLE OF PLANT SPATIAL PATTERN AND FUNCTIONAL DIVERSITY, MAY GREATLY IMPROVE NATURAL RESOURCE MANAGEMENT, AS WELL AS RESTORATION TECHNIQUES BASED ON WATER HARVESTING TECHNIQUES. THE OBJECTIVE OF THIS PROPOSAL IS THE STUDY AND MODELLING OF THE RELATIONSHIPS AMONG SPATIAL PATTERN, DIVERSITY, AND HYDROLOGICAL FUNCTION BY PERFORMING MANIPULATIVE EXPERIMENTS THAT ALLOW TO SEPARATELY TEST THE EFFECTS OF PLANT SPATIAL PATTERN AND DIVERSITY, AND THEIR INTERACTIONS, ON THE HYDROLOGICAL BEHAVIOUR OF SEMIARID ECOSYSTEMS. IN ADDITION, THE PROJECT WILL EVALUATE THE EFFECT OF THE CHANGES IN THE SOURCE-SINK SPATIAL PATTERN DRIVEN BY THE RESTORATION ACTIONS ON CATCHMENT HYDROLOGY, AND WILL DEVELOP HYDROLOGICAL FUNCTION INDICATORS THAT RESULT FROM THE PLANT SPATIAL PATTERN.
