: The research employs various statistical analysis methods, each grounded in specific scientific assumptions, as outlined below:(1) The lavaan package used for structural equation modeling is based on the following scientific assumptions and statistical principles: data normality hypothesis; causal linear relationship hypothesis; residual independence hypothesis; model correctness assumption; parameter uniqueness hypothesis; hypothesis of sample randomness and independence.(2) Pearson correlation analysis uses the following scientific assumptions: continuous variable hypothesis; data normality hypothesis; data linear relationship hypothesis; data independence assumption; the homoscedasticity hypothesis.(3) The SIMPER method relies on the following scientific assumptions and theoretical foundations: the similarity measure hypothesis; sample independence hypothesis; data normalization hypothesis; the explainability hypothesis of differences between groups; nonparametric method hypothesis; data additivity assumption.(4) The scientific assumptions underlying the RDA analysis method in vegan package are as follows: linear relationship hypothesis; data normality hypothesis; variance homogeneity hypothesis; non-multicollinearity hypothesis; sample independence hypothesis.
