- ... Black Soil in Japanese forests is believed to have formed under grasslands, on the basis of pollen and stable carbon isotopic analyses. Carbon stable isotope ratios (δ¹³C) have indicated that the δ¹³C value widely ranged from −25 to −17 ‰ in various land-use soils. We measured the δ¹³C of soil organic carbon (SOC) in Black Soil in forests from northern (43°N) to southern (31°N) Japan. The δ¹³C val ...

- ... Radiocarbon isotopes are increasingly being used to investigate the age and source of carbon released from peatlands. Here we use combined¹⁴C and δ¹³C measurements to determine the isotopic composition of soil and soil decomposition products [dissolved organic carbon (DOC), CO₂and CH₄] in a peatland–riparian–stream transect, to establish the isotopic signature and potential connectivity between ca ...
