AB  - Extremely acidic soils of natural forests in Nanling National Nature Reserve have 
      been previously investigated and revisited in two successive years to reveal the 
      active ammonia oxidizers. Ammonia-oxidizing archaea (AOA) rather than 
      ammonia-oxidizing bacteria (AOB) were found more functionally important in the 
      extremely acidic soils of the natural forests in Nanling National Nature Reserve. 
      The relative abundances of Nitrosotalea, Nitrososphaera sister group, and 
      Nitrososphaera lineages recovered by ammonia monooxygenase subunit A (amoA) 
      transcripts were reassessed and compared to AOA communities formerly detected by 
      genomic DNA. Nitrosotalea, previously found the most abundant AOA, were the 
      second-most-active lineage after Nitrososphaera sister group. Our field study 
      results, therefore, propose the acidophilic AOA, Nitrosotalea, can better reside 
      in extremely acidic soils while they may not contribute to nitrification 
      proportionately according to their abundances or they are less functionally 
      active. In contrast, the functional importance of Nitrososphaera sister group may 
      be previously underestimated and the functional dominance further extends their 
      ecological distribution as little has been reported. Nitrososphaera 
      gargensis-like AOA, the third abundant lineage, were more active in summer. The 
      analyses of AOA community composition and its correlation with environmental 
      parameters support the previous observations of the potential impact of organic 
      matter on AOA composition. Al(3+), however, did not show a strong adverse 
      correlation with the abundances of functional AOA unlike in the DNA-based study. 
      The new data further emphasize the functional dominance of AOA in extremely 
      acidic soils, and unveil the relative contributions of AOA lineages to 
      nitrification and their community transitions under the environmental influences.
