Genetically- and environmentally-dependent processes drive interspecific and intraspecific divergence in the Chinese relict endemic genus Dipteronia [0.03%]
中国特有孑遗属植物刺果藤属的种间和种内分化受遗传和环境因素的影响
Tao Zhou,Xiaodan Chen,Jordi López-Pujol et al.
Tao Zhou et al.
China is a hotspot of relict plant species that were once widespread throughout the Northern Hemisphere. Recent research has demonstrated that the occurrence of long-term stable refugia in the mountainous regions of central and south-wester...

•A new species Laiyangia compacta gen. et sp. nov. with unusual female spikes was described from the Laiyang Formation.•This species shows transitional morphology between early ephedroid and modern gnetoid.•The epidermal microstructural ...
Strong evidence for latitudinal diversity gradient in mosses across the world [0.03%]
全球范围内苔类植物多样性纬度梯度的有力证据
Hong Qian,Zun Dai,Jian Wang
Hong Qian
Species richness generally decreases with increasing latitude, a biodiversity gradient that has long been considered as one of the few laws in ecology. This latitudinal diversity gradient has been observed in many major groups of organisms....
Increased dependence on nitrogen-fixation of a native legume in competition with an invasive plant [0.03%]
入侵植物竞争下本土豆科植物对固氮的依赖增加
Meixu Han,Haiyang Zhang,Mingchao Liu et al.
Meixu Han et al.
Suppression of roots and/or their symbiotic microorganisms, such as mycorrhizal fungi and rhizobia, is an effective way for alien plants to outcompete native plants. However, little is known about how invasive and native plants interact wit...
Salicylic acid positively regulates maize defenses against lepidopteran insects [0.03%]
水杨酸通过激活玉米对鳞翅目昆虫的防卫反应来促进植物生长发育

Yohannes Besufekad Setotaw et al.
In response to insect attack, plants use intricate signaling pathways, including phytohormones, such as jasmonate (JA), ethylene (ET), and salicylic acid (SA), to activate defenses. Maize (Zea mays) is one of the most important staple food ...
Yajun Wang,Hanchen Wang,Chao Ye et al.
Yajun Wang et al.
Orchidaceae are one of the largest families of angiosperms in terms of species richness. In the last decade, numerous studies have delved into reconstructing the phylogenetic framework of Orchidaceae, leveraging data from plastid, mitochond...
Origin and evolution of a new tetraploid mangrove species in an intertidal zone [0.03%]
一种新的四倍体红树物种的起源、进化及其在潮间带生态系统中的生态位分化
Hui Feng,Achyut Kumar Banerjee,Wuxia Guo et al.
Hui Feng et al.
Polyploidy is a major factor in the evolution of plants, yet we know little about the origin and evolution of polyploidy in intertidal species. This study aimed to identify the evolutionary transitions in three true-mangrove species of the ...
Yanjun Du,Rongchen Zhang,Xinran Tang et al.
Yanjun Du et al.
The timing of flowering is an important driver of species distribution and community assembly patterns. However, we still have much to learn about the factors that shape flowering diversity (i.e., number of species flowering per period) in ...
Evaluating the relative importance of predictors in Generalized Additive Models using the gam.hp R package [0.03%]
使用gam.hp R包评估广义可加模型中预测因子的相对重要性
Jiangshan Lai,Jing Tang,Tingyuan Li et al.
Jiangshan Lai et al.
Generalized Additive Models (GAMs) are widely employed in ecological research, serving as a powerful tool for ecologists to explore complex nonlinear relationships between a response variable and predictors. Nevertheless, evaluating the rel...
Aboveground biomass stocks of species-rich natural forests in southern China are influenced by stand structural attributes, species richness and precipitation [0.03%]
中国南方富集树种天然林的地上生物量贮量受林分结构特征、物种丰富度和降水的影响
Wen-Hao Zeng,Shi-Dan Zhu,Ying-Hua Luo et al.
Wen-Hao Zeng et al.
Forests, the largest terrestrial carbon sinks, play an important role in carbon sequestration and climate change mitigation. Although forest attributes and environmental factors have been shown to impact aboveground biomass, their influence...
