Variations in the archaeal community and associated methanogenesis in peat profiles of three typical peatland types in China.

ABSTRACT:

Background

Peatlands contain about 500 Pg of carbon worldwide and play a dual role as both a carbon sink and an important methane (CH₄) source, thereby potentially influencing climate change. However, systematic studies on peat properties, microorganisms, methanogenesis, and their interrelations in peatlands remain limited, especially in China. Therefore, the present study aims to investigate the physicochemical properties, archaeal community, and predominant methanogenesis pathways in three typical peatlands in China, namely Hani (H), Taishanmiao (T), and Ruokeba (R) peatlands, and quantitively determine their CH₄ production potentials.

Results

These peatlands exhibited high water content (WC) and total carbon content (TC), as well as low pH values. In
