Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:

Rasmussen, Janet K.

Abstract:

In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

Isotopic composition of respired CO2 in a small watershed : development and testing of an automated sampling system and analysis of first year data

Creator:

Hauck, Mark J.

Abstract:

Warming of the terrestrial biosphere due to the anthropogenic addition of carbon dioxide to the earth’s atmosphere is becoming a major focus of scientific inquiry. Predictions of the extent of this warming are hampered by uncertainty in the ability of the earth’s ecosystems to counteract this effect by sequestering carbon...
