Relationships between five niche metrics and seven factors for all species. The reference categories selected for assessing relative effects of categorical factors are plants and introduced unintentionally. Standardized effect sizes of each factor are represented by the mean of 24,000 Bayesian posterior values estimated with 80% credible intervals (CI; thick lines) and 95% CI (thin lines). Points are filled if the 80% CI does not overlap with zero and gray if the CI includes zero.
