Interspecific association of woody plant species and community stability in the Eleutharrhena macrocarpa habitat

Abstract

Abstract:

Eleutharrhena macrocarpa, an endangered liana species, experiences population regeneration barriers in natural environments. Due to its endangered status, this species has been heavily researched to understand the mechanisms behind its rarity. In this study, we studied E. macrocarpa populations in the tropical seasonal rainforest of Taiyanghe Provincial Nature Reserve in Pu’er City, Yunnan Province to find successful protecting methods for a wild plant species with extremely small populations. Utilizing various community stability and interspecific competition metrics (the Godron stability index, Chi-square analysis, Pearson correlation), the results showed that the woody plant populatios of tree layer indicated significant positive correlation based on the value of variance ratio more than one (test statistic W > χ_0.05(29)). Similarly, the woody plant populations of shrub layer indicated that no significant negative correlation and the variance ratio is less than 1 (χ_0.95(29)< W < χ_0.05(29)). Further, Chi-square test indicated that no association species pairs represented the most populations in the tree and shrub layer, and the ratios of positive and negative correlations were 0.238 and 0.279, respectively. Simultaneously, association coefficient suggested that significant and extremely significant negative species pairs were more than positive species pairs, while Pearson correlation coefficient indicated that the ratios of the positive and negative correlation were 0.376 and 0.511, respectively. We found that the association relationship of most species pairs showed no significant correlation, which mean a relative stronger interspecific independence. Eleutharrhena macroarpa population has similar adaptive niche with most woody plant populations in the tree layer, and they survived together through effective resource utilization. However, Eleutharrhena macrocarpa population had stronger competition with some species in the shrub layer. In addition, intersection point of community stability (33.92, 66.07) in the vegetative community of Eleutharrhena macrocarpa habitat suggested that the community displayed a better stability. The stronger interspecific competition between dominant species and other species also suggested the vulnerability of tropical seasonal rain forest. Therefore, strict protection of the habitat was crucial to the regeneration of Eleutharrhena macrocarpa population and biodiversity conservation.

Key words: tropical seasonal rain forest, variance ratio, interspecific association, interspecific correlation, Godron stability index
