Description
Cecilia Ghiazza and co-authors present a 2026 study on methane-cycling microbes in two South American reservoirs. Hydro dams are seen as clean, yet their waters emit methane, a potent greenhouse gas. Microbes in the mud both make and consume that methane. The team sampled mud at three sites in each of two nearby nutrient-rich reservoirs across seasons.
Gene scans sorted the maker and eater groups, and lab jars measured their peak rates. Eater activity always beat maker activity in the tests. The two groups rose and fell together, which suggests tight coupling all year. Each reservoir held a distinct community mix, even though the same few types led in both. Makers were the more dynamic and diverse side.
