Lake characteristics influence how methanogens in littoral sediments respond to terrestrial litter inputs

Shallow lake sediments harbor methanogen communities that are responsible for large amounts of CH₄ flux to the atmosphere. These communities play a major role in degrading in-fluxed terrestrial organic matter (t-OM)-much of which settles in shallow near-shore sediments. Little work has examined how sediment methanogens are affected by the quantity and quality of t-OM, and the physicochemical factors that shape their community. Here, we filled …
