Abstract

Complete ammonia oxidizers (comammox Nitrospira) are ubiquitous in coastal wetland sediments and play an important role in nitriﬁcation. Our study examined the impact of habitat modiﬁcations on comammox Nitrospira communities in coastal wetland sediments across tropical and subtropical regions of so...
