Scale and the isotopic record of C 4 plants in pedogenic carbonate: from the biome to the rhizosphere
The 13 C/ 12 C ratio in pedogenic carbonate (i.e., CaCO 3 formed in soil) is a significant tool for investigating C 4 biomes of the past. However, the paleoecological meaning of δ 13 C values in pedogenic carbonate can change with the scale at which one considers the data. We describe studies of mod...
