In the unrelated combination, the positive association between 13 C enrichment and P concentration became stronger under neighbor zero P and reached significance ( Figure 3 ; p < 0.05), whereas in the kin combination, the fitted relationship under neighbor zero P shifted toward a negative trend and did not show a significant correlation.
