Abundance of ammonia monooxygenase subunit A (amoA) genes determined using TaqMan quantitative polymerase chain reaction (qPCR). Archaeal amoA genes were quantified using quantitative PCR using the assay described in Mosier and Francis 2011. Complete methods are described in Santoro et al., submitted.
