Keystone species affect the relationship between soil microbial diversity and ecosystem function under land use change in subtropical China

Fan Yang, Qiong Chen, Qian Zhang, Chunyan Long, Wei Jia & Cheng Xiaoli
Soil microbial diversity affects soil chemical cycling and ecosystem function. However, how highly connected keystone species regulate associated microbial structure and function (of the whole community and of specialized species), irrespective of their abundance under land use change, remains unresolved. Here, we identified the relationship between microbial diversity [soil phospholipid fatty acid (PLFA) richness and composition, and ammonia-oxidizing archaea and bacteria (AOA and AOB) communities] with both a broad (i.e., microbial respiration) and specialized function...

Speciation along the elevation gradient: divergence of Roscoea species within the south slope of the Himalayas

Jian-Li Zhao, Babu Ram Paudel, Xiang-Qin Yu, Jie Zhang & Qing-Jun Li
The Himalayas with dramatic elevation gradient is one of the global biodiversity hotspots. Although origin of biodiversity of the Himalayas is of great concern, the speciation process within the Himalayas is poorly known. Roscoea within the Himalayas serve as a good model system to test the speciation process along an elevation gradient. 32375 unlinked SNPs were used to reconstruct phylogenetic relationships and introgression analyses in D-statistics and Fastsimicoal2. Species distribution modeling (SDM) was used to...

Qiong Cai, Erik Welk, Chengjun Ji, Wenjing Fang, Francesco Maria Sabatini, Jianxiao Zhu, Jiangling Zhu, Zhiyao Tang, Fabio Attorre, Juan Antonio Campos, Andraž Čarni, Milan Chytrý, Süleyman Çoban, Jürgen Dengler, Jiri Dolezal, Richard Field, József Pál Frink, Hamid Gholizadeh, Adrian Indreica, Ute Jandt, Dirk Nikolaus Karger, Jonathan Lenoir, Robert K. Peet, Remigiusz Pielech, Michele De Sanctis … & Helge Bruelheide
This dataset could be used to test whether the commonly observed positive range size–niche breadth relationship, as posited by the “niche breadth hypothesis”, exists for Fagus, one of the most dominant and widespread broad‐leaved deciduous tree genera in temperate forests of the Northern Hemisphere. There are many ways to estimate niche breadth. Here, we estimated biotic and climatic niche breadths per species using plot‐based co‐occurrence data and climate data, respectively. The range sizes of the...

Global distribution and evolutionary transitions of angiosperm sexual systems

Yunyun Wang, Ao Luo, Tong Lyu, Dimitar Dimitrov, Xiaoting Xu, Robert Freckleton, Yaoqi Li, Xiangyan Su, Yichao Li, Yunpeng Liu, Denis Sandanov, Qingjun Li, Zhanqing Hao, Shuguang Liu & Zhiheng Wang
Angiosperm sexual systems are fundamental to the evolution and distribution of plant diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain poorly known. Using data on sexual systems and distributions of 68453 angiosperm species, we present the first global maps of sexual system frequencies and evaluate sexual system evolution during the Cenozoic. Frequencies of dioecy and monoecy increase with latitude, while hermaphrodites are more frequent in warm and arid regions. Transitions to...

Recognition of dominant driving factors behind sap flow of Liquidambar formosana based on back-propagation neutral network method

Jie Tu, Qijing Liu & Jianping Wu
Aims: This study focused on the applicability of back-propagation (BP) neural networks in simulating sap flow (SF) using meteorological factors and a phenological index (PI) for Liquidambar formosana, a deciduous broad-leaf tree species in subtropical China, and thus providing a useful and promising alternative to traditional methods for transpiration prediction. Methods: Three-layered BP models with an architecture 4-10-1 (four neurons in the input layer, ten neurons in the hidden layer and one neuron in the...

Arundinella tengchongensis (Poaceae), a name at new rank and newly combined based on morphological and molecular data

Liqiong Jiang, Hua Peng & Yue-Hua Wang
To clarify the taxonomic status of Arundinella setosa var. tengchongensis and its relationships with A. setosa var. setosa and other related species, molecular phylogenetic analyses based on nuclear ITS and two plastid DNA (matK and trnL-F) sequences, and morphological comparisons using one-way ANOVA were carried out. Our results reveal that A. setosa var. tengchongensis is recovered within a different clade and separated from the type variety. Morphologically, A. setosa var. tengchongensis can be easily distinguished...

Dataset from: Warming effects on grassland productivity depend on plant diversity

Junjiong Shao, Xuhui Zhou, Kees Van Groenigen, Guiyao Zhou, Huimin Zhou, Lingyan Zhou, Meng Lu, Jianyang Xia, Lin Jiang, Bruce Hungate, Yiqi Luo, Fangliang He & Madhav Thakur
Aim: Climate warming and biodiversity loss both alter plant productivity, yet we lack an understanding of how biodiversity regulates the responses of ecosystems to warming. In this study, we examine how plant diversity regulates the responses of grassland productivity to experimental warming using meta-analytic techniques. Location: Global Major taxa studied: Grassland ecosystems Methods: Our meta-analysis is based on warming responses of 40 different plant communities obtained from 20 independent studies on grasslands across five continents....

Stronger effect of litter quality than microorganisms on leaf and root litter C and N loss at different decomposition stages following a subtropical land use change

Chang Liao, Chunyan Long, Qian Zhang & Xiaoli Cheng
Litter decomposition contributes largely to global carbon (C) and nitrogen (N) cycling, and it is strongly determined by litter quality and microbial community composition in ways that are poorly understood. Here, we conducted a 2-year field litter decomposition experiment by collecting leaf and root litter of crops (from cropland), shrubs (from shrubland), and wood (from woodland) and placing samples for decomposition in woodland soil in central China to investigate the effects of litter quality and...

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....

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:...

Paraphlomis longicalyx (Lamiaceae), a new species from the limestone area of Guangxi and Guizhou Provinces, southern China

Ya-Ping Chen, Zeng-Peng Sun, Jin-Fei Xiao, Ke-Jian Yan & Chun-Lei Xiang
Consisting of approximately 30 species, the genus Paraphlomis of the mint family are mostly restricted to the subtropical area of China. In this study, Paraphlomis longicalyx, a new species from southern China, is described and illustrated. Molecular phylogenetic studies were carried out to investigate the placement of the new species within Paraphlomis based on two nuclear ribosomal DNA and four plastid DNA regions. The results show that P. longicalyx is recovered as a distinct lineage...

Dataset of spillover effects of protected areas on the QTP

Yu Shen, Guohua Liu, Wei Zhou, Yuqing Liu, Hao Cheng & Xukun Su
Aim: Although protected areas (PAs) are assumed to reduce threats to nature within boundaries, their spillover effects remain equivocal. It is necessary to not only determine whether PAs truly achieve conservation targets but also whether they promote or inhibit natural habitat degradation in adjacent areas by blockage or leakage spillover. This study aims to choose 54 nature reserves (NRs) focusing on forest protection as a case study to assess PA conservation effectiveness and spillover prevalence....

Data from: A new species of the Cambrian bivalved euarthropod Pectocaris with axially differentiated enditic armatures

Changfei Jin, Huijuan Mai, Dayou Zhai, Hong Chen, Yu Liu, Xianguang Hou & Ruilin Wen
Although first described in 1999, the early Cambrian Pectocaris remains a poorly known euarthropod genus. As of now, two species, Pectocaris eurypetala and Pectocaris spatiosa, are known from the Chengjiang biota. Here, we report a third species, Pectocaris inopinata sp. nov., which bears a pair of stalked eyes attached to an anterior sclerite, a pair of short but stout antennae, 29–35 cephalothoracic segments each corresponding to a pair of biramous appendages, 11–12 limbless segments carrying...
