Differences in microbial community structure and nitrogen cycling in natural and drained tropical peatland soils.

ABSTRACT: Tropical peatlands, which play a crucial role in the maintenance of different ecosystem services, are increasingly drained for agriculture, forestry, peat extraction and human settlement purposes. The present study investigated the differences between natural and drained sites of a tropical peatland in the community structure of soil bacteria and archaea and their potential to perform nitrogen transformation processes. The results indicate significant dissimilarities in the structure of soil bacterial and archaeal communities as well as nirK, nirS, nosZ, nifH and archaeal amoA gene-possessing microbial communities. The reduced denitrification and N₂-fixing potential was detected in the drained tropical peatland soil. In undisturbed peatland soil, the N₂O emission was
