Dear Colleagues, The next SFS meeting (Annual meeting of the Society for Freshwater Science) will take place in Sacramento, California from May 21-26, 2016. More information is available here: http://sfsannualmeeting.org/ We are organizing a special session for the meeting entitled Ecohydrology of intermittent rivers and ephemeral streams in the face of a changing climate change. A large proportion of the global river network is composed of intermittent rivers and ephemeral streams (IRES). While IRES have been historically overlooked by freshwater scientists, research in the past decade has led to a better understanding of their ecohydrology and biodiversity. Growing evidence suggests that IRES contribute substantially to catchment-scale biodiversity and organic matter processing. From an ecosystem perspective, the biota and biogeochemistry of the alternating aquatic and terrestrial phases of IRES are intricately linked. In addition, IRES provide important ecosystem services to human societies. In turn, IRES are now receiving increased attention from water resource managers. Due to climate change and increased freshwater demands, the relative proportion of IRES may be increasing in many regions. Drying event frequency and duration in natural IRES are increasing and once-perennial rivers are becoming intermittent. This special session will present the latest research on the ecohydrology of IRES in the context of climate change, and address potential challenges in managing these ecosystems. Wed like to invite you to contribute to this special session. If youre interested, wed appreciate receiving a tentative title and brief description of the expected content of your presentation (oral or poster) by early-January 2016. This will help us organize an exciting session. Both registration and abstract submission are now open. The deadline for abstract submission is 29 January 2016 and guidelines for abstract preparation are provided here: http://sfsannualmeeting.org/ We are looking forward to seeing you in this promising Special Session!
