Title: Ecohydrology in water-stressed environments: the effects of climate change

Abstract: Intrinsic water-limited ecosystems cover at least 40% of the global land surface and most other ecosystems will experience water stress (e.g., drought) at certain stage. In water-stressed ecosystems, patterns of water availability constrain the vegetation spatial and temporal dynamics, and vegetation has strong feedbacks to water cycle.  This talk will discuss how to use stable isotopes as a powerful tracer to enhance our understanding of ecohydrological processes in water-stressed environments and the responses to a changing environment.  Specifically, this talk will focus on two main questions, 1) how to partition evapotranspiration and what is the warming effect on evapotranspiration partitioning; and 2) how to identify the origins of non-rainfall water (e.g., fog and dew) in extremely water-limited environments and how to differentiate fog and dew formations using novel isotope techniques.
