From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Na2S2O3对植物修复Hg污染土壤的影响

open access: yesShuitu Baochi Xuebao, 2011
为研究添加化学调控剂对植物修复Hg污染土壤的影响,寻找经济有效的Hg污染土壤的植物修复手段.采用盆栽试验,研究添加Na2S2O3后对金盏菊(Kalendae)和芥菜(Mustum)修复Hg污染土壤的影响.Na2S2O3的加入促进了植物对各形态Hg的吸收,植物修复后土壤中各形态Hg的含量表现为残留态>过氧化氢态>酸溶态>碱溶态>水溶态.高浓度的Na2S2O3对植物生长产生一定的抑制作用,同时也会抑制土壤Hg向植物体内迁移.Na2S2O3浓度为1 mg/kg时,植物对Hg的吸收量最大 ...

DNA Barcoding Reveals Cryptic Diversity and Informs Conservation Priorities in Chinese Firmiana Species (Malvaceae) Using Genome Skimming Data DNA条形码揭示中国梧桐属 (锦葵科) 隐存多样性及保护优先级:来自基因组浅层测序数据的证据

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.
Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

3种有机酸对伴矿景天修复效率及土壤微生物数量的影响

open access: yesShuitu Baochi Xuebao, 2020
伴矿景天(Sedum plumbizincicola)是一种Cd和Zn的超积累植物,常用于Cd污染土壤的植物修复。有机酸能够提高土壤重金属的有效性,促进植物对重金属的积累,对重金属污染土壤的植物修复效率具有强化作用,并对土壤微生物数量有重要影响。以河潮土和红黄泥为供试土壤,探讨了乙二胺四乙酸(EDTA)、柠檬酸、草酸对伴矿景天修复效率和土壤微生物数量的影响。结果表明,有机酸能显著提高土壤有效态Cd含量,柠檬酸处理的效果最好,河潮土和红黄泥中有效态Cd含量较单种伴矿景天分别增加72.73%,12.99 ...

Mitigation of Legacy Effects in Invaded Soil via Alien Plant‐Derived Biochar 题目:外来植物生物炭对其入侵后土壤遗留效应的修复作用

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.
The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

Ecological Restoration of Rubber Monocultures: Strategies for Biodiversity and Ecosystem Recovery in Tropical Regions 题目:如何将橡胶林恢复为多样森林?

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 345-353, September 2025.
Restoration of monoculture in protected and marginal areas can be organized into two phases (1) identification and prioritization of restoration sites based on remote sensing or field survey then assessing degradation level, and (2) implementation of appropriate restoration interventions.
