TL;DR: The results imply that new rhizodeposit-C is rapidly processed by fungal communities and only much later by the bacterial communities, which is attributed to either a fungal-mediated translocation of rhizosphere-C from the fungal to bacterial biomass or a preferential bacterial use of dead root or fungal necromass materials as C source over the direct utilization of fresh root-exudate C in these N-limited grassland ecosystems.

TL;DR: It is demonstrated that saprotrophic fungi produce methane without the involvement of methanogenic archaea, suggesting a common methane formation pathway in fungal cells under aerobic conditions and identifying fungi as another source of methane in the environment.

TL;DR: In a wide range of arid and forested regions, cryptogamic covers appear to be the dominant source of N2 O, and it is suggested that greenhouse gas emissions associated with this source might increase in the course of global change due to higher temperatures and enhanced nitrogen deposition.

TL;DR: The results suggest that soil macro-fauna, anaerobic soil microsites or both combined may provide suitable conditions for CH4 production in otherwise oxic soil environments, with a potential impact on the CH4 sink capacity of these soils.

TL;DR: The absence of methanogenic archaea within the algal culture and the oxic conditions during CH4 formation suggest that the widespread marine algae Emiliania huxleyi might contribute to the observed spatially and temporally restricted CH4 oversaturation in ocean surface waters.
