Research Emphasis:

My goal in the GCE/LTER program is to expand the information that I've obtained to date on the patterns of fungal productivity in shoot-decomposition systems of saltmarshes. At present, I have three years of seasonal data for the smooth- cordgrass and black-needlerush systems for Sapelo Island marshes, and autumn data for these two grasses and for black grass along the east coast of the USA from Florida to Maine (published or in manuscript). The LTER work will allow longer-term collection of data, and extend data gathering into fresher-water environments. Another goal is to learn more about potential interactions among eukaryotic and prokaryotic organoosmotrophs of marshgrass decomposition systems as a product of the GCE Decomposer-Consortia Experiments (Hodson, Hollibaugh, Moran, Newell).
