Distinguishing biological and physical controls on soil respiration

Creator:

Phillips, Claire L.

Abstract:

Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include soil moisture, temperature, and substrate quality, have been known for some time. Nevertheless, correlations between these drivers and...

The effects of water and shade treatments on photosynthesis and root-rhizosphere respiration in young ponderosa pine

Creator:

Johnson, Theresa J.

Abstract:

Water treatments were applied to young ponderosa pine trees in the Eastern Cascades, Oregon during the 2003 growing season, and shade treatments were applied during the 2003 and 2004 growing seasons to understand how photosynthesis and soil respiration, particularly the root/rhizosphere fraction (R[subscript rrh]), would respond to increased moisture availability...
