The root systems of forest trees are composed of different diameters and heterogeneous physiological traits. However, the pattern of root respiration rates from finer and coarser roots across various tropical species remains unknown. To clarify how respiration is related to the morphological traits of roots, we evaluated specific root respiration and its(More)
We investigated inter-annual variation of canopy CO2 exchange (NEE) and evapotranspiration during a 7-year period over a lowland Dipterocarp forest in Pasoh, Peninsular Malaysia, using the eddy covariance method. Annual rainfall fluctuated between 1,451 and 2,235 mm during this period. Annual evapotranspiration estimated by energy budget correction and gap(More)
The co-chairs of the IPCC Expert Group on Land-use Change and Forestry are Sandra Brown and Youba Sokona. We are grateful to the many scientists and inventory experts who contributed to this report, including:
We observed diurnal and seasonal patterns of leaf-scale gas exchange within the crown of a Dipterocarpus sublamellatus Foxw. tree growing in a lowland dipterocarp forest at Pasoh, Peninsular Malaysia. Observations were carried out nine times over 6 years, from September 2002 to December 2007. Observation periods included both wet and mild-dry periods, and(More)
Field observations were conducted at Bukit Tarek Experimental Watershed in Peninsular Malaysia to investigate the relationship between rainfall-runoff responses and variation in soil moisture in a tropical rain forest. Stormflow depended strongly on the antecedent wetness as represented by the initial runoff rate. Though heavy rains fell in almost every(More)
Soil physical properties and water movement within soil were investigated using dyes in a tropical rain forest, the Bukit Tarek Experimental Watershed of Peninsular Malaysia. The saturated hydraulic conductivity (K s) decreased with increasing soil depth. TheK s values were higher than those reported for other tropical soils. The geometric means of theK s(More)
The Tier 1 method disaggregates the production data and import/export data into categories of wood fuels, slash, and short and longer-term roundwood production and products. Two categories of decay are distinguished. Emissions from the short-lived product pool are released in the first year and a single decay rate is applied to all longer-lived products.(More)
