Statistical analysis
Significant differences were analyzed using the G -test of
heterogeneity in establishment success rate (Sokal & Rohlf 2012), and
the non-parametric Mann-Whitney U test in mean abundance between the
test group and the control group. One-way ANOVA with Tukey’s multiple
comparison test was performed to compare differences in mean abundance
at the population and community levels, average speed, average adjacency
distance, and cumulative contact time of goldfish between the control
group and the multispecies groups.
