How does species rarity influence the functional diversity and resilience along the successional pathway in heterogeneous karst forests?

Global climate change and human activities have increased the risk of rare species loss due to their sensitivity to disturbances. Considering their dominance in hyper-diverse communities, the contribution pathways and extent of rare species loss to functional diversity and resilience should be clarified. Therefore, we established 30 forest dynamic plots in heterogeneous degraded karst forests and measured the plant functional traits along the successional pathway. The correlations between trait uniqueness and species rarity were quantified, and the effects of rare and common species losses on functional diversity and trait networks were simulated. The correlations between trait uniqueness and species rarity showed rare species tended to occupy marginal functional space positions in the mid and late successional stages. In addition, rare species mainly supported functional redundancy in the early successional stage and significantly impacted functional resilience. In contrast, the unique..., , # How does species rarity influence the functional diversity and resilience along the successional pathway in heterogeneous karst forests?

## Description of the data and file structure

We have submitted our datasets from karst forest, including: raw data of plant species abundance (SC_abundance.csv, SG_abundance.csv, OG_abundance.csv) and plant leaf trait (SC_traits.csv, SG_traits.csv, OG_traits.csv) for early, mid, and late successional stages respectively; R script for analyses (01_FUZZYQ.R, 02_FUNSPACE.R, 03_FUNDIVERSITY.R, 04_FUNNETWORK.R); and a species code file (Species_name.csv).

全球气候变化与人类活动加剧了稀有物种的灭绝风险，因稀有物种对干扰更为敏感。鉴于其在超多样群落（hyper-diverse communities）中占据主导地位，亟需阐明稀有物种丧失对功能多样性（functional diversity）与功能恢复力（functional resilience）的贡献路径及影响程度。
为此，我们在异质化退化喀斯特森林（heterogeneous degraded karst forests）中设立了30个森林动态样地（forest dynamic plots），并沿群落演替序列（successional pathway）测定了植物功能性状（plant functional traits）。本研究量化了性状独特性（trait uniqueness）与物种稀有性（species rarity）之间的相关性，并模拟了稀有物种与常见物种丧失对功能多样性及性状网络（trait networks）的影响。
性状独特性与物种稀有性的相关性分析结果显示，在演替中、后期，稀有物种往往占据功能空间（functional space）的边缘位置。此外，稀有物种在演替早期主要维持功能冗余（functional redundancy），并对功能恢复力具有显著影响。与之相对，[原文未完成内容]…… # 异质化退化喀斯特森林中，物种稀有性如何沿群落演替序列影响功能多样性与功能恢复力？
