BACTERIAL PROCESSING OF DOC - WHAT CONTROLS ARE REALLY IMPORTANT AT AN ECOSYSTEM SCALE?
 
In Toolik Lake, Alaska, we examined the microbial use of DOC with bioassays, with experiments in 5m^3 limnocorrals, and with ecosystem-scale measurements during spring runoff. Results indicate (1) inorganic nutrients alone had little effect; (2) adding terrestrial DOC increased bacterial numbers and production 2.5 and 30 times, respectively, compared to the control -- this response indicated that at least some portion of the
