The results are mean ± SD. Capital letters represent the comparison between two species in the same place. Lowercase letters represent the comparison of the same species between two areas. T-test is used when the data conform to the normal distribution, and Mann–Whitney U test is used when the data do not conform to the normal distribution, p < 0.05, n = 5.
