Community composition and activities of denitrifying bacteria in soils

Creator:

Rich, Jeremy J.

Abstract:

Few studies have directly compared denitrifying community composition and activities in soils by coupling molecular-genetic techniques and traditional measures of denitnfication. I investigated communities of denitrifying bacteria from adjacent meadow and forest soils in the Cascade Mountains, Oregon. A key gene in the denitrification pathway, N₂O reductase (nosZ), served as...

Dissertation
Denitrification potential in forest riparian soils of the western Oregon Cascades : spatial and temporal variation

Creator:

McClellan, Michael H.

Abstract:

Denitrification, the biological or chemical reduction of ionic nitrogen oxide or dinitrogen, has not been widely studied in forest ecosystems despite widespread interest in other facets of the forest nitrogen economy. This study had three main objectives: to determine whether potential for denitrification exists in forest riparian and hill slope...

Masters Thesis
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...
