    Distribution of different plant life forms on tropical islands: patterns and underlying mechanisms by Chengfeng Yang, Jingyan Zhao, Shengzhuo Huang, Shurong Zhou, Yikang Cheng

    Published 2025-04-01
    “…IntroductionIsland biogeography theory posits that both island area and isolation significantly influence species distribution patterns and community structure. This study investigates the effects of island area and isolation on plant community structure, specifically focusing on the variation in species richness and abundance among different plant life forms (i.e., trees and shrubs) on tropical islands in the South China Sea.MethodsWe surveyed woody plants and collected soil samples from 20 tropical islands in the South China Sea, analyzing how island area, isolation, climate and soil factors influence plant communities across different life forms (trees vs. shrubs).ResultsThe results indicate that species richness increases with island area and decreases with isolation, which aligns with the classic predictions of island biogeography. …”
