Homogenization of Detrital Leachate in an Old-Growth Coniferous Forest, OR : DOC Fluorescence Signatures in Soils Undergoing Long-Term Litter Manipulations

Creator:

Strid, April R.

Abstract:

Soil dissolved organic carbon (DOC) is a small but crucial part of the forest carbon cycle. Characterizing the relationship between detrital inputs and soil DOC chemistry is crucial to understanding the ultimate fate of root carbon, fallen wood and needles. Chemical differences in the DOC pool may help to explain...

Response of soil microbial communities and nitrogen cycling processes to changes in vegetation inputs

Creator:

Brewer, Elizabeth Ann

Abstract:

Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...

Contributions of ammonia-oxidizing bacteria and archaea to nitrification in forest soils

Creator:

Lu, Xinda

Abstract:

Prior to 2005, ammonia oxidation, the first step of nitrification, was thought mediated mainly by ammonia-oxidizing bacteria (AOB). However, the discovery of Thaumarchaeota carrying the genes coding for the ammonia monooxygenase (AMO) enzyme led to the discovery that ammonia-oxidizing archaea (AOA) also contribute to nitrification. Despite the uptick in studies...
