Biomass carbon stocks and stock changes in managed hedgerows
Science of The Total Environment, 2023Landscape features, such as hedgerows, can play a role in enhancing terrestrial carbon (C) sinks, especially in North-western Europe, where they form a large part of the agricultural landscape. To date, there are few studies relating aerial imagery to ground-truthed biomass measurements and relating changes in biomass to hedgerow management. This study

Cataloguing Soil Carbon Stocks
Science, 2010In their Report (“Terrestrial gross carbon dioxide uptake: Global distribution and covariation with climate,” 13 August, p. [834][1]), C. Beer et al. joined others ([ 1 ][2], [ 2 ][3]) in estimating global carbon fluxes and their relationship to climate.

Tropical peatlands have changed their role from carbon sinks to carbon sources mainly by recent anthropogenic disturbances. It is an urgent issue to evaluate the importance of tropical peatlands as carbon stocks and to preserve the ecosystems including their carbon dynamics. Spatial distribution of carbon mass at a regional level needs to be delineated

Total soil carbon (C) stock comprises of the soil organic C (SOC) and the soil inorganic C (SIC) components. The global SOC stock of ice-free land contains about 1,325–1,500 Pg (1 Pg = 1015 g) C in the top 1 m, 2,300 Pg C in the top 3 m, and 3,000 Pg C in the soil profiles.

Phytoplankton, the free-floating tiny microscopic floral particles, demonstrate a wide range of shapes and vary over several orders of magnitude in size, from submicron species such as the picoplanktonic prochlorophytes to diatoms measuring more than 1 mm in diameter. In mixed-pieces samples, high numbers of extremely small-sized species might actually

The aim of this chapter was to quantify the soil organic carbon (SOC) stock in the top 30 cm of mineral soil for the whole Italian territory, according to the different land use types of the Intergovernmental Panel on Climate Change (IPCC) cropland category (arable land, agroforestry, vineyards, olive groves, orchards and rice fields), as a basis for ...

Soil carbon stocks in Sarawak, Malaysia
Science of The Total Environment, 2013The relationship between greenhouse gas emission and climate change has led to research to identify and manage the natural sources and sinks of the gases. CO2, CH4, and N2O have an anthropic source and of these CO2 is the least effective in trapping long wave radiation.

Carbon stocks in Scottish peatlands
Soil Use and Management, 2009Abstract Various estimates have suggested that the peatlands of Scotland are a significant deposit of fixed carbon. However, these have been based upon rather imprecise estimates of peat depth. Using previously unused archived data, we have mapped peat depth across the country and then used these values to obtain an improved value of ...

Permafrost and Wetland Carbon Stocks
Science, 2010In their Report “Global convergence in the temperature sensitivity of respiration at ecosystem level” (13 August, p. [838][1]), M. D. Mahecha et al. have done a fine study to tease apart the distinction between intrinsic and apparent temperature sensitivities ([ 1 ][2]).
