Effects of grazing prohibition on nirK- and nirS-type denitrifier communities in salt marshes.

ABSTRACT:

Introduction

Grazing prohibition is an effective management practice to restore salt marsh functioning. However, the effects of grazing exclusion on denitrifying microbial communities and their controlling factors in salt marshes remain unclear.

Methods

In this study, we surveyed soil physicochemical properties and above- and below-ground biomass and using quantitative polymerase chain reaction and Illumina MiSeq high-throughput sequencing technology to determine the relative abundance, composition, and diversity of nitrite reductase nirS- and nirK-type denitrifying bacterial communities associated with grazing prohibition treatments and elevations.

Results

The abundance of nirS-type denitrifiers increased with grazing prohibition time, whereas th
