Data from: Plant-type dominates fine-root C:N:P stoichiometry across China: a meta-analysis

Zhiqiang Wang, Shiqi Lv, Hui Song, Mingcheng Wang, Qi Zhao, Heng Huang & Karl Niklas
Aim: Fine roots play an important role in biogeochemical cycling in terrestrial ecosystems. However, our understanding of large scale biogeographic patterns and drivers of fine-root C:N:P stoichiometry is extremely limited. Location: China. Methods: We compiled data for fine-root carbon (C), nitrogen (N) and phosphorus (P) concentrations at 165 sites across China to explore large-scale biogeographic patterns and drivers of fine-root C:N:P stoichiometry. Results: The geometric means of fine-root C, N, and P concentrations were 448.81...

Life history predicts flight muscle phenotype and function in birds

Shane DuBay, Yongjie Wu, Graham Scott, Yanhua Qu, Qiao Liu, Joel Smith, Chao Xin, Andrew Hart Reeve, Chen Juncheng, Dylan Meyer, Jing Wang, Jacob Johnson, Zachary Cheviron, Fumin Lei & John Bates
1. Functional traits are the essential phenotypes that underlie an organism’s life history and ecology. Although biologists have long recognized that intraspecific variation is consequential to an animals’ ecology, studies of functional variation are often restricted to species-level comparisons, ignoring critical variation within species. In birds, interspecific comparisons have been foundational in connecting flight muscle phenotypes to species-level ecology, but intraspecific variation has remained largely unexplored. 2. We asked how age- and sex-dependent demands on...

Assigning the sex-specific markers via genotyping-by-sequencing onto the Y chromosome for a torrent frog Amolops mantzorum

Luo Wei, Xia Yun, Yue Bisong & Zeng Xiaomao
We use a genotyping-by-sequencing (GBS) approach to identify sex-linked markers in a torrent frog (Amolops mantzorum) using wild-caught individuals of 21 males and 19 females from the same population. A total of 141 putatively sex-linked markers were screened from 1,015,964 GBS tags through three approaches, respectively based on sex differences in allele frequencies, sex difference in heterozygosity, and sex-limited occurrence. With validations, 69 sex-linked markers were confirmed, all of which point to male heterogamety. The...

Livestock grazing promotes ecosystem multifunctionality of a coastal saltmarsh

Pei Zhang, Zaichao Yang & Jihua Wu
The effects of livestock grazing on grasslands have garnered much attention; however, little is known about how grazing affects ecosystems’ ability to simultaneously support multiple ecosystem functions (i.e., ecosystem multifunctionality, hereafter EMF) in coastal saltmarshes. To comprehensively evaluate the ecological effects of livestock grazing and tidal flooding on saltmarshes, we conducted a grazing-exclusion experiment in the high and middle marsh zones of the Yangtze River Estuary, China. Livestock grazing generally enhanced EMF in the salt...

Data from: Phylogenetic conservatism and biogeographic affinity influence woody plant species richness-climate relationships in eastern Eurasia

Xiangyan Su, Nawal Shrestha, Xiaoting Xu, Denis Sandanov, Qinggang Wang, Siyang Wang, Dimitar Dimitrov & Zhiheng Wang
Mechanisms underlying species richness patterns remain a central yet controversial issue in biology. Climate has been regarded as a major determinant of species richness. However, the relative influences of different evolutionary processes, (i.e. niche conservatism, diversification rate, and time for speciation) on species richness-climate relationships remain to be tested. Here, using newly compiled distribution maps for 11,422 woody plant species in eastern Eurasia, we estimated species richness patterns for all species and for families with...

Leaf size of woody dicots predicts ecosystem primary productivity

Yaoqi Li, Peter Reich, Bernhard Schmid, Nawal Shrestha, Xiao Feng, Tong Lyv, Brian Maitner, Xiaoting Xu, Yichao Li, Dongting Zou, Zheng-Hong Tan, Xiangyan Su, Zhiyao Tang, Qinghua Guo, Xiaojuan Feng, Brian Enquist & Zhiheng Wang
A key challenge in ecology is to understand the relationships between organismal traits and ecosystem processes. Here, with a novel dataset of leaf length and width for 10,480 woody dicots in China and 2,374 in North America, we show that the variation in community mean leaf size is highly correlated with the variation in climate and ecosystem primary productivity, independent of plant life form. These relationships likely reflect how natural selection modifies leaf size across...

The perfect storm: Gene tree estimation error, incomplete lineage sorting, and ancient gene flow explain the most recalcitrant ancient angiosperm clade, Malpighiales

Liming Cai, Zhenxiang Xi, Emily Lemmon, Alan Lemmon, Austin Mast, Christopher Buddenhagen, Liang Liu & Charles Davis
The genomic revolution offers renewed hope of resolving rapid radiations in the Tree of Life. The development of the multispecies coalescent (MSC) model and improved gene tree estimation methods can better accommodate gene tree heterogeneity caused by incomplete lineage sorting (ILS) and gene tree estimation error stemming from the short internal branches. However, the relative influence of these factors in species tree inference is not well understood. Using anchored hybrid enrichment, we generated a data...

Data: Abiotic niche divergence of homoploid hybrid species from their progenitors

Danying Wang, Chen Shao, Yingying Zhu, Zhenxiang Xi, Xiaoting Xu & Jianquan Liu
Although more frequently reported recently than was previously expected, the role of ecology in the speciation of homoploid hybrid species (HHS) has not been quantitatively evaluated. We examined divergences in the niches of 22 assumed HHS (18 plants and four animals) from those of their progenitors using 52097 occurrences and 26 environmental factors (temperature, precipitation, altitude and soil). We identified three niche divergence patterns in HHS, niche novelty, niche contraction and niche intermediacy, by estimating...

Data from: Allopatric divergence and hybridization within Cupressus chengiana (Cupressaceae), a threatened conifer in the northern Hengduan Mountains of western China

Jialiang Li, Richard Ian Milne, Dafu Ru, Jibin Miao, Wenjing Tao, Lei Zhang, Jingjing Xu, Jianquan Liu & Kangshan Mao
Having a comprehensive understanding of population structure, genetic differentiation and demographic history is important for the conservation and management of threatened species. High‐throughput sequencing (HTS) provides exciting opportunities to address a wide range of factors for conservation genetics. Here, we generated HTS data and identified 266,884 high‐quality single nucleotide polymorphisms from 82 individuals of Cupressus chengiana , to assess population genomics across the species' full range, comprising the Daduhe River (DDH), Minjiang River (MJR) and...

Enhanced Heterogenous Hydration of SO2 Through Immobilization of Pyridinic-N on Carbon Materials

Wanglai Cen, Longhua Zou, Ping Yan, Peng Lu, Dongyao Chen & Wei Chu
Carbon materials doped with nitrogen has long been utilized for SO2 removal from flue gases for the benefits of environment. The role of water is generally regarded as hydration of SO3 which is formed through the oxidization of SO2. However, the hydrolysis of SO2, especially on the surface of N doped carbon materials, was almost ignored. In this study, the hydrolysis of SO2 was investigated in detail on the pyridinic nitrogen (PyN) doped graphene (GP)...

Blow to the Northeast? Intraspecific differentiation of Populus davidiana suggests a northeastward skew of a phylogeographic break boundary in East Asia

Xiaoyan Fan, Xinya Song & Richard I. Milne
Aim: There is increasing interest in the role that biological traits, and historical and biogeographic processes, play in the formation of phylogeographic patterns. An arid belt that once existed in northern China might have affected many plants, but this has yet to be untested in an arid-tolerant, wind-dispersed species. Here we tested how intrinsic and extrinsic factors have affected the phylogeography of Populus davidiana. Location: East Asia Methods: Genetic variation was surveyed across 40 populations...

A novel SNP of MYO1A gene associated with heat-tolerance in Chinese cattle

Yanhong Cao, Peng Jia, Zhuyue Wu, Mingguang Huang, Shaomei Chen, Jicai Zhang, Bizhi Huang & Chuzhao Lei
With the advent of global climate change, heat-tolerance is becoming more and more important to the sustainability of animal husbandry production systems. Previous studies have shown that MYO1A gene associated with pigmentation may be closely related to heat-tolerance in cattle. In this study, a novel missense mutation (NC_037332.1 g.56390345 A > G) was first detected in MYO1A in 891 individuals of 35 cattle breeds, which transformed the amino acid isoleucine into valine. The purpose of...
