Explore the data for this trait in the portal

• Label: Leaf stable oxygen isotope composition (delta18O)
• Entity URI: https://w3id.org/APD/traits/trait_0003072
• Type: numeric
• Definition: Oxygen stable isotope ratio [ECSO:00001740], d18O [ECSO:00001677], of leaves [PO:0025034].;Oxygen stable isotope ratio, d18O, of leaves.
• Additional comments: delta18O is calculated as the ratio of, 18O/16O in a sample to 18O/16O in a standard, minus 1. The result is expressed in parts per thousand, commonly referred to as per mille. A lower value for delta18O indicates the sample has a lower ratio of 18O/16O relative to the standard.
• units: {delta}[ppth]
• allowable range: -10 - 50 {delta}[ppth]
