Dear Colleagues, We would like to remind you to consider submitting an abstract for the session on human effects on inland freshwater biogeochemistry at the 2014 Joint Aquatic Sciences Meeting in Portland (http://www.freshwater-science.org/Annual-Meeting/2014-Portland---JASM.aspx). The description for our session is below, abstract deadline is Feb 7, 2014, THIS FRIDAY!. Please pass along to anyone you think would be interested.
Thanks again!

Agricultural and urban areas occupy approximately 45% of the terrestrial landscape and affect biogeochemical cycling locally and globally. Human dominated watersheds are often characterized by land clearing, soil disturbance, increased nutrient loading, and hydrological alteration (e.g. storm and tile drains). These changes that characterize impacted landscapes alter how nutrients are transported and cycled at the watershed scale, water clarity, oxygen levels, community composition, trophic interactions, and contaminant bioaccumulation pathways within food webs. We seek presentations aimed at a fundamental understanding of how anthropogenic landscape alterations impact aquatic biogeochemistry (sources, transport, transformations, and metabolism). We are particularly interested in highlighting work that utilizes novel methods to identify and trace the sources and fate of nutrients (including carbon) and field or modeling studies that seek to understand the processing of nutrients in the context of the coupled nature of the hydrologic and biogeochemical cycles in watersheds. All freshwater environments are of interest, including wetlands, groundwater, rivers, lakes, and streams.
