• Label: Leaf stable carbon isotope composition (delta13C)
• Entity URI: https://w3id.org/APD/traits/trait_0003012
• Type: numeric
• Definition: Carbon stable isotope ratio [ECSO:00001142], d13C [ECSO:00000669], of leaves [PO:0025034].;Carbon stable isotope ratio, d13C, of leaves.
• Additional comments: delta13C is calculated as the ratio of, 13C/12C in a sample to 13C/12C in a standard, minus 1. The result is expressed in parts per thousand, commonly referred to as per mille. A more negative value for delta13C indicates the sample has a lower ratio of 13C/12C relative to the standard.
• units: {delta}[ppth]
• allowable range: -50 - 0 {delta}[ppth]
