Elevated microbial network complexity and enriched methanogens contribute to higher methanogenic potential in hollows than in hummocks in alpine meadows - Environmental Microbiome Background Glacier foreland meadows are hotspots of methane emissions, with hollows emitting more methane than adjacent hummocks. While previous work has attributed these differences mainly to variati...
