TI  - Community shift of ammonia-oxidizing bacteria along an anthropogenic pollution 
      gradient from the Pearl River Delta to the South China Sea.

AB  - The phylogenetic diversity and abundance of ammonia-oxidizing beta-proteobacteria 
      (beta-AOB) was analyzed along an anthropogenic pollution gradient from the 
      coastal Pearl River Delta to the South China Sea using the ammonia monooxygenase 
      subunit A (amoA) gene. Along the gradient from coastal to the open ocean, the 
      phylogenetic diversity of the dominant genus changed from Nitrosomonas to 
      Nitrosospira, indicating the niche specificity by these two genera as both 
      salinity and anthropogenic influence were major factors involved. The diversity 
      of bacterial amoA gene was also variable along the gradient, with the highest in 
      the deep-sea sediments, followed by the marshes sediments and the lowest in the 
      coastal areas. Within the Nitrosomonas-related clade, four distinct lineages were 
      identified including a putative new one (A5-16) from the different sites over the 
      large geographical area. In the Nitrosospira-related clade, the habitat-specific 
      lineages to the deep-sea and coastal sediments were identified. This study also 
      provides strong support that Nitrosomonas genus, especially Nitrosomonas 
      oligotropha lineage (6a) could be a potential bio-indicator species for pollution 
      or freshwater/wastewater input into coastal environments. A suite of statistical 
      analyses used showed that water depth and temperature were major factors shaping 
      the community structure of beta-AOB in this study area.
