For system metabolism we will seasonally sample, using the Open Stream Diel O2 Method, where we collect two-station O2, temperature, Photosynthetic active radiation (PAR), water velocity and water level.
Anthropogenic Allochthony: potential sources of elevated respiration in human-influenced rivers, storage behind impoundments. We expect the metabolism of the river to change, in particular in regards to the amount heterotrophy and allochthony (expected to decrease with the removal of dams).
