The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:

Boyle, Stephanie A.

Abstract:

The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...

Carbon cycling and priming of soil organic matter decomposition in a forest soil following glucose additions

Creator:

Diaz, David D.

Abstract:

Soils are a globally significant carbon (C) pool and have the potential to respond to elevated CO2 and environmental changes through positive feedback cycles that enhance the turnover of soil organic matter (SOM). Understanding the mechanisms governing the turnover of SOM is particularly important for modeling the fate of C...

OF THE THESIS OF David D. Diaz for the degree of Master of Science in Soil Science presented on
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...
