We investigated the relative importance of CH 4 and CO2 fluxes from soil and termite mounds at four different sites in the tropical savannas of northern Australia near Darwin and assessed different methods to indirectly predict CH4 fluxes based on CO 2 fluxes and internal gas concentrations. The annual flux from termite mounds and surrounding soil was dominated by CO 2 with large variations among sites. On a carbon dioxide equivalent (CO 2-e) basis, annual CH4 flux estimates from termite mounds…

Comparison of the regional CO 2 mole fraction filtering approaches at a WMO/GAW regional station in China

Abstract. The identification of atmospheric CO2 observation data which are minimally influenced by very local emissions/removals is essential for trend analysis, for the estimation of regional

Termites Facilitate Methane Oxidation and Shape the Methanotrophic Community

It is concluded that termites modify their environment, resulting in higher methane oxidation and selecting and/or enriching for a distinct methanotroph population.

Termite mound emissions of CH4 and CO2 are primarily determined by seasonal changes in termite biomass and behaviour

It is highlighted for the first time that seasonal termite population dynamics are the main driver for the observed seasonal differences in mound fluxes of CH4 and CO2.

The effect of termite biomass and anthropogenic disturbance on the CH4 budgets of tropical forests in Cameroon and Borneo

The exchange of CH4 between tropical forests and the atmosphere was determined by simultaneously measuring the net CH4 flux at the soil surface and assessing the flux contribution from soil‐feeding

Methane emission by termites and oxidation by soils, across a forest disturbance gradient in the Mbalmayo Forest Reserve, Cameroon

Methane fluxes were measured, using static chambers, across a disturbance gradient in a West African semi‐deciduous humid forest. Soil‐feeding termite biomass was simultaneously determined, in an

Fluxes of CH4 and CO2 from soil and termite mounds in south Sudanian savanna of Burkina Faso (West Africa)

The contribution of West African savanna ecosystems to global greenhouse gas budgets is highly uncertain. In this study we quantified soil‐atmosphere CH4 and CO2 fluxes in the southwest of Burkina

Field studies of methane emission from termite nests into the atmosphere and measurements of methane uptake by tropical soils

The flux of CH4 and CO2 from termite nests into the atmosphere has been measured in a broad-leafed-type savannah in South Africa. Measurements were carried out on nests of species of six genera,

The Importance of Termites to the CH4 Balance of a Tropical Savanna Woodland of Northern Australia

This study presents the first estimate of CH4 emissions from termites based on replicated in situ seasonal flux measurements in Australian savannas, and determined net CH4 flux within a tropical savanna woodland of northern Australia.

Methane oxidation by termite mounds estimated by the carbon isotopic composition of methane

Emission rates and carbon isotope ratios of CH4, emitted by workers of termites, and of CH4, emitted from their mounds, were observed in a dry evergreen forest in Thailand to estimate the proportion

The influence of termites on atmospheric trace gases: CH4, CO2, CHCl3, N2O, CO, H2, and light hydrocarbons

Based on field studies of mounds of Australian termites we estimate that on a global scale termites emit about 12 × 1012 g/yr of methane (< 20 tg/yr) and about 4 ×1015 g CO2/yr (< 8 pg/yr). Most of
