Evaluation of an automated respiration method used in assessing the toxicity of zinc on soil microorganisms

Creator:

Boening, Dean W.

Abstract:

Microorganisms can be a valuable tool in assessing the toxicity of heavy metals. The soil respiration rate is a commonly explored endpoint. I utilized a fully automated respirometer incorporating an infrared gas analyzer (IRGA) and developed a method for measuring the effect of Zn on soil microbial populations. Zinc, in...

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...
