a Hypotheses about the influences of various factors were checked by a structural equation model. Positive and negative paths are shown as blue and red lines, respectively, and nonsignificant paths are shown in gray. b–e Mixed linear models were fitted for vital paths. The site was used as the random factor to address nonindependence between samples. The colored envelope surrounding each line represents 95% of linear mixed models.
