Measuring nitrification, denitrification, and related biomarkers in continental geothermal ecosystems
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 beenused for measuring nitrification and denitrification in hot spring environments,including isotope pool dilution and tracer approaches, and the acetylene blockapproach. The chapter also summarizes qualitative and quantitative methodsfor measurement of functional and phylogenetic biomarkers of thermophilespotentially involved in these processes
