Niche specialization and prevalence of comammox Nitrospira in the alkaline sediments of thermokarst lakes on the Tibetan Plateau
Complete ammonia-oxidizing (comammox) Nitrospira are recognized as key players in the nitrogen cycle, yet their ecological roles in extreme environments remain poorly understood. Here, we show that comammox Nitrospira occupy distinct ecological niches in Tibetan Plateau thermokarst lakes (pH 7.5–10.2) using stable isot...
