Specifically, a highly significant decreasing trend was observed in H e between CH87 and CH94 ( Fig 3a ; r = -1.000, P < 0.001; b = -0.113, P < 0.001), whereas significant increasing trends were observed in H e between CH78–CH87 ( Fig 3a ; r = 1.000, P < 0.05; b = 0.038, P < 0.05) and between CH00-CH10 ( Fig 3a ; r = 1.000, P < 0.01; b = 0.007, P < 0.001), as well as, in N A between CH00–CH10 ( Fig 3c ; r = 1.000, P < 0.01; b = 0.105, P < 0.001).
