Dear Colleagues, We would like you to consider submitting an abstract for the session on human effects on inland freshwater biogeochemistry at the 2014 Joint AquaticSciences 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. Please pass along to anyone you think would be interested.
Apologies for cross postings Best, Rebecca Barnes (Rutgers) Henry Wilson (Agriculture and Agri-Food Canada) David Butman (U.S. Geological Survey / Yale University / University of Washington) *29 Anthropogenic Influences on Watershed Biogeochemistry: New Findings and Methods* Anthropogenic sources of dissolved and particulate nutrients have profoundly impacted aquatic ecosystems and water quality over the entire planet. 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. -- *Rebecca Barnes* Postdoctoral Associate Institute of Marine & Coastal Sciences Rutgers, State University of New Jersey 71 Dudley Road, New Brunswick, NJ 08901 848.932.3421 https://sites.google.com/site/beccabarnes/
