AB: The growing focus on ecohydrology and increasing popularity of the term is largely driven by the need to respond to a future of continuing environmental change. Our current ability to forecast impacts of change and determine the best ways to mitigate negative changes is limited. A way around this limitation is through the integration of ecological and hydrological sciences to build a better conceptual and quantitative understanding of how interactions between rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources. In our view, ecohydrology is a hybrid discipline that seeks to elucidate (a) how hydrological processes influence the distribution, structure, function, and dynamics of biological communities, and (b) how feedbacks from biological communities affect the water cycle [modified from Nuttle, 2002]. In this tutorial we will discuss the definition(s) and origins of the term ecohydrology. We will also describe the potential that can be realized by building an integrated ecohydrological science perspective. Case studies will be used to illustrate some key ecohydrological concepts and identify current research needs. Nuttle, W.K. 2002. Eco-hydrology's past and future in focus. Eos, Trans.
