Elevated microbial network complexity and enriched methanogens contribute to higher methanogenic potential in hollows than in hummocks in alpine meadows

Key Points

• This research aims to explore the differences in microbial composition and methane production between hollows and hummocks in alpine meadows.
• Analyzed microbial community composition in hollows and hummocks
• Assessed methanogenic potential in both environments
• Examined interactions and dynamics of methane-cycling
• Hollows exhibited higher microbial network complexity than hummocks
• Increased abundance of methanogens in hollows contributed to greater methane production
• Distinct differences in methane-cycling dynamics were found between the two environments
