TL;DR: The annual export of fluvial organic carbon from both intact peat swamp forest and peat Swamp forest subject to past anthropogenic disturbance is quantified to improve estimates of the impact of deforestation and drainage on tropical peatland carbon balances.

TL;DR: Close agreement is found between the ‘top-down’ and combined ‘bottom-up’ estimates of large CH4 emissions from trees adapted to permanent or seasonal inundation can account for the emission source that is required to close the Amazon CH4 budget.

TL;DR: It is shown that tree stems emit substantially more methane than peat surfaces, accounting for 62-87% of total ecosystem methane flux, and the need to integrate this emission pathway in both field studies and models if wetland methane fluxes are to be characterized accurately in global methane budgets is highlighted.

TL;DR: This study reveals an emergent pattern of increasing suppression of methane (CH(4)) emission from peatlands with increasing sulfate (SO(4)(2-)-S) deposition, within the range of global acid deposition, and suggests that sulfur pollution may currently counteract climate-induced growth in the wetland source.

TL;DR: Simple relationships developed from combining external drivers (deposition, temperature) and site conditions (nitrogen status of soils) can successfully estimate nitrogen leaching from forests that have not yet been highly damaged by N deposition.
