AB: The interactive manner by which abiotic and biotic determinants of resource availability lead to the formation and maintenance of observed ecological patterns is critical to the development of theories regarding the dynamics and diversity of terrestrial ecosystems. Similarly, the challenge of understanding the mechanisms by which the spatial pattern of hydrological fluxes arise within the dynamics of surface hydrological processes is central to the practice of hydrology. In this regard, the space-time distribution of soil moisture provides a crucial link between hydrological and biogeophysical processes through its controlling influence on transpiration, runoff generation, carbon assimilation and nutrient absorption by plants. The emerging science of ecohydrology has provided a framework for the integrated analysis of the coupled ecological-geophysical processes that govern surface water balance in terrestrial landscapes. My talk will focus on the spatial aspects of ecohydrological interactions between plants, soils, and climates in semi-arid landscapes, and will seek to link observed patterns in vegetation organization with the hydrological dynamics operating within landscapes organized around river networks and those that are not.
