Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Shuitu Baochi Xuebao, 2007 植被恢复是退化生态系统重建的重要途径，植被恢复过程中物种多样性的变化反映了植被的恢复程度，通过群落调查，研究了太行山片麻岩区植被恢复过程中群落物种多样性特征及其与土壤含水量之间的关系，结果表明：物种多样性指数天然灌木群落〉人工乔木群落。乔木和灌木群落各指数大小为封禁20年〉封禁10年〉封禁5年。6种群落其土壤含水量均偏低，随着封禁时间的加长，含水量略为增加，但天然灌木群落平均含水量稍大于人工群落。不同封禁时间群落土壤含水贯与均匀度指数成正相关，多样性指数与含水量先呈正相关，在封禁20年时，呈负相关 ...

Comparative study on community ecology of transition zone along Eucalyptus citriodora to Acacia confusa forest stands [PDF]
, 2011 近年来，外来树种桉树在我国大量种植，产生了巨大的经济效益，但同时，其速生性、较强的化感作用等特性，也带来一些负面的环境问题，评估桉树种植的环境生态影响成为当前林业生态研究的热点。目前大量的研究集中在桉树群落生态学上，而关于桉树与乡土树种过渡带的群落生态学的综合比较研究未见报道。 为此，本文针对无居民海岛柠檬桉（Eucalyptuscitriodora）林与台湾相思（Acaciaconfusa）林过渡带三种林分林下层植被群落生态、林分凋落物及其分解动态进行了研究 ...

Exploring the importance of aromatic plants' extrafloral volatiles for pollinator attraction
New Phytologist, Volume 248, Issue 2, Page 517-528, October 2025.Summary Aromatic plants occur in many plant lineages and have widespread ethnobiological significance. Yet, the ecological significance and evolutionary origins of aromatic volatile emissions remain uncertain. Aromatic emissions have been implicated in defensive interactions but may also have other important functions.

Integrative Conservation, Volume 4, Issue 3, Page 491-502, September 2025.The impact of various restoration strategies on biodiversity and biomass in degraded savannas was evaluated across different elevation gradients. Natural regeneration co‐benefits the increasing in biodiversity and biomass in savannas, while active restoration exhibits altitude‐dependent efficacy and lower biomass accumulation capacity.
