1 Terrestrial carbon in aquatic ecosystems: experimental tests of the subsidy-stability hypothesis Stuart E. Jones & Jay T. Lennon

2 Producer-Decomposers Phytoplankton-Bacterioplankton Organic Carbon Organic Nutrients Inorganic Carbon Inorganic Nutrients ProducerDecomposer Subsidy

3 Terrestrial DOC is an increasing subsidy to aquatic ecosystems Findlay 2005 Frontiers in Ecology and the Environment Hudson River, Northeast USA Water color ~ DOC Allochthony Carpenter et al. 2005; Jansson et al. 2007

4 Does terrestrial DOC influence aquatic metabolic stability?

5 Carbon Loading

6 Result of Manipulation Water Color (m -1 ) DOC (mg L -1 )

7 DOC isnt just a subsidy… High DOC Low DOC

8 Next steps… Metabolism data Microbial loop coupling ???
