Methane emission rates were highest in streams affected by agriculture and urbanization, likely because the accumulation of fine sediments in these streams promoted sediment anoxia and methane production. My dissertation research demonstrates that headwater streams are sources of greenhouse gases to the atmosphere, but that N2O emissions have been overestimated while CH4 emissions have been overlooked.	cache/td96k071r66.txt	txt/td96k071r66.txt
