The presence of heterozygous individuals in a population is crucial for maintaining genetic diversity, which can positively affect fitness and adaptability to environmental changes. While inbreeding generally reduces the proportion of heter...
Morphological adaptation strategy of invasive plant Ambrosia trifida seed distributed along rivers is closely related to soil nutrients [0.03%]
豚草沿河不同生境土壤养分对其入侵适应性的影响研究
Yufeng Xu,Chenyang Xue,Xuezhi Wang et al.
Yufeng Xu et al.
Rivers are crucial in the spread of invasive plants. Invasive plants alter their seed traits to adapt to environmental changes and promote invasion. Studying the trait changes in invasive plant seeds may improve the understanding of their p...
Drought tolerance traits explain differential stem growth rates of evergreen and deciduous trees in a tropical karst forest [0.03%]
干旱耐受性状解释了喀斯特森林中常绿树和落叶树茎生长速率的差异
Yu-Mei Yan,Ze-Xin Fan,Pei-Li Fu et al.
Yu-Mei Yan et al.
The karst forest in southwestern China is characterized by thin soil layers, numerous fissures and holes, resulting in low soil water availability and poor water retention, making it challenging for plant growth and survival. While the rela...
Consistent spatial-temporal variations of stigmatic pollen load among co-flowering species across six sub-alpine meadows [0.03%]
六片亚高山草甸上六个同季开花物种柱头上的花粉负载的时空变化规律

Co-flowering species may have evolved strategies to avoid or tolerate the adverse effects of heterospecific pollen deposition. However, the precondition for this evolutionary response is spatial-temporal stability, an aspect currently under...
Parallel loss of anthocyanins triggers the incipient sympatric speciation in an alpine ginger [0.03%]
平行的花青素丧失触发高山姜属近缘物种的同步形成
Zhi-Li Zhou,Tial C Ling,Jian-Li Zhao et al.
Zhi-Li Zhou et al.
Change of flower color can readily lead to a shift in pollinators, potentially causing pollinator mediated reproductive isolation or even speciation. Here, we examined the ecological and evolutionary consequences of flower color polymorphis...
Plant use of water across soil depths regulates species dominance under nitrogen addition [0.03%]
植物在不同土层中利用水分调节氮添加下的物种优势度变化
Fu-Qiang Huang,Josep Peñuelas,Jordi Sardans et al.
Fu-Qiang Huang et al.
The primary mechanism driving plant species loss after nitrogen (N) addition has been often hypothesized to be asymmetric competition for light, resulting from increased aboveground biomass. However, it is largely unknown whether plants' ac...

Lang Li 李朗 et al.
Over the past two decades, our understanding of Lauraceae, a large family of woody plants, has undergone significant advances in phylogeny, taxonomy, and biogeography. Molecular systematic studies have elucidated the basic relationships wit...
Resistance of plant diversity to road disturbance: Evidence from the Tibetan Plateau [0.03%]
青藏高原植物多样性对公路干扰的抵抗性研究
Ziwei Chen,Dongsheng Zhao,Siqi Deng et al.
Ziwei Chen et al.
The expansion of road networks in recent decades has drawn considerable attention due to its impact on biodiversity in high-altitude ecosystems. Here, we conducted a comprehensive field survey to investigate the effects of road disturbance ...
Increased dependence on mycorrhizal fungi for nutrient acquisition under carbon limitation by tree girdling [0.03%]
环割引起的碳限制下树木对菌根真菌依赖性增强以获取养分
Jing Chen,Jingjing Cao,Binglin Guo et al.
Jing Chen et al.
Nutrient acquisition through symbiotic ectomycorrhizal fungi is carbon (C) costly but fundamental for plant growth, community, and ecosystem functioning. Here, we examined the functions of roots and mycorrhiza with respect to nutrient uptak...
Climate-driven environmental filtering determines hump-shaped elevational pattern of seed plant beta diversity in the central Himalayas [0.03%]
气候驱动的环境筛选决定了喜马拉雅中部种子植物β多样性单峰式海拔格局
Jianchao Liang,Zhifeng Ding,Ganwen Lie et al.
Jianchao Liang et al.
Understanding how and why assemblage dissimilarity changes along spatial gradient is a great challenge in ecology, because answers to these questions depend on the analytical types, dimensions, and components of beta diversity we concerned....
