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
Tao Zhang,Qiang Fang

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...
