Variation in communities of ammonia-oxidizing and denitrifying bacteria in Fennoscandian boreal forest soils

Creator:

Ghimire, Rama D.

Abstract:

The objective of this study was to examine the variation among ammonia-oxidizing and denitrifying communities in soils of a natural Fennoscandian boreal forest and of a forest with a long history of fertilization with different levels of nitrogen (N), and to examine whether there are any changes in the microbial...

Ammonia-oxidizer and denitrifier populations in boreal forest soils of differing nitrogen availability

Creator:

Burton, Marci S.

Abstract:

Nitrification and denitrification are major biological processes transforming nitrogen (N) in soils to plant available N, highly leachable nitrate (NO₃⁻) and gaseous N oxides. Although many studies in the past have studied N cycling communities, the effect of increased N inputs on ammonia-oxidizer and denitrifier population dynamics is still under...
