The p values from Mann–Whitney tests with the alternative hypothesis of professional survey generate longer species lists than the community science. Each blue point represents a p value attained from the Mann–Whitney test after resampling, and we performed 1000 replicates for 1 year (a), 5 years (b), 10 years (c), and 15 years (d). The percentage level shows the percentage of 1000 p values that are significant (p < 0.05)
