Species and individual level diversity analysis by location
| Study areas | Haikou | Qiongzhong | Danzhou | Wanning | Sanya | Total |
|---|---|---|---|---|---|---|
| Species level | ||||||
| γ diversity (overall) | 9 | |||||
| α diversity (species richness) | 6 | 8 | 8 | 7 | 7 | 9 |
| True β diversity | 1.50 | 1.13 | 1.13 | 1.29 | 1.29 | – |
| Proportional species turnover βp | 0.33 | 0.11 | 0.11 | 0.22 | 0.22 | – |
| Individual level | ||||||
| Gini-Simpson biodiversity index | 0.17 | 0.31 | 0.42 | 0.07 | 0.38 | 0.14 |
Notes: Diversity measure types: α denotes the diversity within a study site, higher values mean higher diversity; β denotes differences in diversity between samples from a study site and the overall, a value of 1 means that the study site has all the species found in all study sites; γ denotes the total diversity over the set of all samples; βp represents the proportional difference between overall diversity and the diversity in specific study site
