Methane-cycling microbial communities are spatially structured, seasonally dynamic, and functionally coupled in sediments of two nearby eutrophic hydroelectric reservoirs
Ana Fernández-Scavino
Hydroelectric reservoirs, which are expanding worldwide, are freshwater bodies that, despite being considered environmentally friendly, are important sources of methane emissions. Methane emissions vary with the availability of organic matter, especially with season in subtropical reservoirs, as well as with hydrology and reservoir age, watershed properties, and the interactions among methane-producing and consuming microbial populations. This study examined the activity, spatial distribution, a
