Abstract

Research on the nitrogen biogeochemical cycle in terrestrial geothermal ecosystems has recently been energized by the discovery of thermophilic ammonia-oxidizing archaea (AOA). This chapter describes methods that have been used for measuring nitrification and denitrification in hot spring environments, including isotope pool dilution and tracer approaches, and the acetylene block approach. The chapter also summarizes qualitative and quantitative methods for measurement of functional and phylogenetic biomarkers of thermophiles potentially involved in these processes.
