Africa is reported to have 104 hyperdominant species, with a total species count of 4 638, and the hyperdominant percentage is the lowest at 2.23%. Amazonia has the highest number of hyperdominants at 299 and the greatest species richness with 13 826 species, yet its hyperdominant percentage is slightly lower than Africa's at 2.16%. Southeast Asia has 278 hyperdominants with a total of 11 963 species, and the highest hyperdominant percentage among the three regions at 2.32%. The combined total shows 681 hyperdominants out of 30 427 species across the regions, resulting in a hyperdominant percentage of 2.24%. Prediction intervals in brackets provide an estimate of uncertainty, accounting for the variability in the data and the potential error in extrapolation methods used. This table suggests that while Amazonia is the most species-rich, Southeast Asia has a slightly higher proportion of hyperdominants relative to its species count. Table 2 Extrapolated tree species hyperdominance results for African, Amazonian, Southeast Asian tropical forests at the regional scale 2 Analysis of Research Findings The study uncovers a surprisingly consistent pattern of common tree species across the world's most biodiverse ecosystems. This consistency holds true despite varying climatic, biogeographic, and anthropogenic factors across
