Short summary

The niche differentiation of ammonia and nitrite oxidizers is controversial because they display disparate patterns in different environments. Combining molecular and nitrification rate analyses, our study clarified that water mass mixing and the substrate availability primarily regulated the niche differentiation of nitrifier populations along a salinity gradient. The nitrifier populations may have specific adaptations to different substrate conditions through their ecological strategies.
