Species specific plant-mediated effects between herbivores converge at high damage intensity

Jinlong Wan, Jiahui Yi, Zhibin Tao, Zhikun Ren, Evans Otieno, Baoliang Tian, Jianqing Ding, Evan Siemann, Matthias Erb & Wei Huang
Plants are often exposed to multiple herbivores and densities of these attackers (or corresponding damage intensities) generally fluctuate greatly in the field. Plant-mediated interactions vary among herbivore species and with changing feeding intensity, but little is known about how herbivore identity and density interact to determine plant responses and herbivore fitness. Here, we investigated this question using Triadica sebifera (tallow) and its two major specialist insect herbivores, Bikasha collaris (flea beetle) and Heterapoderopsis bicallosicollis (weevil)....

Altitudinal variation of leaf carbon isotope for Dendrosenecio keniensis and Lobelia gregoriana in Mount Kenya alpine zone

Antony Waigwa, Brian Mwangi, Fred Omengo, Gituru Wahiti, Zhou Yangdong & Qingfeng Wang
Abiotic factors vary along altitudinal gradients, and this may influence plant morphology, physiology and function. This study aimed to test the hypothesis that leaf δ13C, a common proxy for water use efficiency, was indirectly influenced by morphological adjustments with changing climatic factors along an altitudinal gradient on Mt. Kenya. We sampled leaves of Dendrosenecio keniensis and Lobelia gregoriana using seventy-two 10 × 10 m plots situated every 100 m starting from 3600 to 4300 m....

Data from: Ponerorchis wolongensis (Orchidaceae, Orchidinae), a new species with variable labellum from Hengduan Mountains, western Sichuan, China

Shuai Peng
Ponerorchis wolongensis, a new orchid species from the Hengduan Mountains, western Sichuan, China, is described and illustrated here based on morphological and phylogenetic evidence. Morphologically, the new species is similar to P. capitata, but they can easily be differentiated by the number of leaves and flowers, the shape of leaves, and the mid-lobe of the labellum. Phylogenetically, based on seven DNA sequences, the new species is more close to P . sichuanica, but these two...

Magnitude and timing of resource pulses interact to affect plant invasion

Zhibin Tao, Changchao Shen, Wenchao Qin, Yinfeng Gui, Evan Siemann, Yi Wang & Wei Huang
Human activities can cause resource fluctuations through reducing uptake by the resident vegetation (e.g., disturbance) or through changing external resource supply (e.g., fertilization). Resource fluctuations often occur as pulses which are low frequency, large magnitude and short duration, and now are recognized as an important driver of plant invasions. However, resource pulses often vary dramatically in a number of attributes, yet how these attributes mediate the impacts of resource pulses on plant invasions remains unclear....

Morphological trait matching in plant–Hymenoptera and plant–Diptera mutualisms across an elevational gradient

Yan-Hui Zhao, Amparo Lazaro, Hai-Dong Li, Zhibin Tao, Huan Liang, Wei Zhou, Zong-Xin Ren, Kun Xu, De-Zhu Li & Hong Wang
Morphological trait-matching and species abundance are thought to be the main factors affecting the frequency and strength of mutualistic interactions. However, the relative importance of trait-matching and species abundance in shaping species interactions across environmental gradients remains poorly understood, especially for plant–insect mutualisms involving generalist species. Here, we characterised variation in species and trait composition and the relative importance of trait-matching and species abundance in shaping plant–Hymenoptera and plant–Diptera mutualisms in four meadows across an...

DNA sequences employed in systematics of Lobelioideae (Campanulaceae): Review, phylogenetic and biogeographic analyses

Samuel Kagame, Lingyun Chen, Andrew Gichira & Qingfeng Wang
Lobelioideae, the largest subfamily within Campanulaceae, includes 33 genera and approximately1200 species. It is characterized by resupinate flowers with zygomorphic corollas and connate anthers and widely distributed across the world. The systematics of Lobelioideae has been quite challenging over the years, with different scholars postulating varying theories. To outline major progress and highlight the existing systematic problems in Lobelioideae, we conducted a literature review on this subfamily. Additionally, we conducted phylogenetic and biogeographic analyses for...

Two leaves that cannot die: the genome sequence of Welwitschia mirabilis reveals its unique biology and evolutionary history

Zhiming Liu, Tao Wan & Qingfeng Wang
Welwitschia mirabilis (hereafter Welwitschia), the sole species in Welwitschiales, belongs to gnetophytes, an ancient, enigmatic gymnosperm lineage. It is a strikingly bizarre plant with distinctive morphology of just two large ever-elongating leaves and is remarkable in being able to survive extreme environmental stresses of the Namibian and Angolan deserts. Here, we provide a chromosome-level assembly of its genome (6.8 Gb/1C) and extensive methylome and transcriptome data to reveal the genetics underpinning its intriguing biology. The...

Multiple diversity facets of crucial microbial groups in biological soil crusts promote soil multifunctionality

Hua Li, Youxin Chen, Gongliang Yu, Federico Rossi, Da Huo, Roberto De Philippis, Xiaoli Cheng, Weibo Wang & Renhui Li
Aim: Microbial diversity is one of the most important factors for maintaining the performance of multiple functions in soils (multifunctionality). However, existing studies typically consider taxonomic richness or Shannon diversity of the entire community. We know little about the connection network of taxonomic and phylogenetic diversity facets and their collective impact on multifunctionality. In this study, the linkages of diversity effects within functional groups were disentangled in drylands. Location: The central Tibetan Plateau. Time period:...
