Data from: Sex-biased gene expression in dioecious garden asparagus (Asparagus officinalis)

Alex Harkess, Francesco Mercati, Hong-Yan Shan, Francesco Sunseri, Agostino Falavigna & Jim Leebens-Mack
Sex chromosomes have evolved independently in phylogenetically diverse flowering plant lineages. The genes governing sex determination in dioecious species remain unknown, but theory predicts that the linkage of genes influencing male and female function will spur the origin and early evolution of sex chromosomes. For example, in an XY system, the origin of an active Y may be spurred by the linkage of female suppressing and male promoting genes. Garden asparagus (Asparagus officinalis) serves as...

Data from: The functional significance of complex floral colour pattern in a food-deceptive orchid

Xiaokai Ma, Jun Shi, Hans Banziger, Yangna Sun, Yanyan Guo, Zhongjian Liu, Steven D. Johnson & Yibo Luo
Many non-rewarding orchid species mimic the signals of co-occurring food flowers and thereby attract food-seeking animal pollinators. These signals are often visually complex with a colour pattern that contrasts between outer and central parts. The significance of this colour complexity for the pollination success of flowers of deceptive orchids has scarcely been investigated. We tested the effects of the colour patterns of the food-deceptive orchid Paphiopedilum micranthum on bumblebee visitation choices and pollination success using...

Data from: Correct calculation of CO2 efflux using a closed-chamber linked to a non-dispersive infrared gas analyzer

Gbadamassi G. O. Dossa, Ekananda Paudel, Hongyan Wang, Kunfang Cao, Douglas Schaefer & Rhett D. Harrison
1. Improved understanding of the carbon (C) cycle is essential to model future climates and how this may feedback to affect greenhouse-gas fluxes. 2 .We summarize previous work quantifying respiration rates of organic substrates and briefly discuss how advances in technology, specifically the use of chambers linked to a non-dispersive infra-red gas analyzer (NDIR), can be applied to assess carbon dynamics from short-term field measurements. This technology hastens measurement and is relatively inexpensive, enabling researchers...

Data from: Community-wide changes in inter-taxonomic temporal co-occurrence resulting from phenological shifts

Fangyuan Hua, Junhua Hu, Yang Liu, Xingli Giam, Tien Ming Lee, Hao Luo, Jia Wu, Qiaoyi Liang, Jian Zhao, Xiaoyan Long, Hong Pang, Biao Wang, Wei Liang, Zhengwang Zhang, Xuejie Gao & Jiang Zhu
Global climate change is known to affect the assembly of ecological communities by altering species’ spatial distribution patterns, but little is known about how climate change may affect community assembly by changing species’ temporal co-occurrence patterns, which is highly likely given the widely observed phenological shifts associated with climate change. Here we analyzed a 29-year phenological data set comprising community-level information on the timing and span of temporal occurrence in 11 seasonally occurring animal taxon...

Data from: Fewer new species colonize at low frequency N addition in a temperate grassland

Yunhai Zhang, Carly J. Stevens, Xiaotao Lü, Nianpeng He, Jianhui Huang & Xingguo Han
1. Biologically reactive nitrogen (Nr) enrichment threatens biodiversity in diverse ecosystems. Previous controlled N addition experiments may overestimate the effects of atmospheric Nr deposition on the rate of species loss, as it has been found that low frequency Nr additions, as used in traditional studies, lead to more rapid biodiversity loss. It remains unclear, however, whether the colonization of new species (gain) or extinction of old species (loss) is the cause of this difference. 2....

Data from: Using plant functional traits and phylogenies to understand patterns of plant community assembly in a seasonal tropical forest in Lao PDR

Manichanh Satdichanh, Jérôme Millet, Andreas Heinimann, Khamseng Nanthavong & Rhett D. Harrison
Plant functional traits reflect different evolutionary responses to environmental variation, and among extant species determine the outcomes of interactions between plants and their environment, including other plant species. Thus, combining phylogenetic and trait-based information can be a powerful approach for understanding community assembly processes across a range of spatial scales. We used this approach to investigate tree community composition at Phou Khao Khouay National Park (18°14’-18°32’N; 102°38’- 102°59’E), Laos, where several distinct forest types occur...

Data from: Phylogeny and classification of the East Asian Amitostigma alliance (Orchidaceae: Orchideae) based on six DNA markers

Ying Tang, Tomohisa Yukawa, Richard M. Bateman, Hong Jiang & Hua Peng
Background: Tribe Orchideae dominates the orchid flora of the temperate Northern Hemisphere but its representatives in East Asia had been subject to less intensive phylogenetic study than those in Eurasia and North America. Although this situation was improved recently by the molecular phylogenetic study of Jin et al., comparatively few species were analyzed from the species-rich and taxonomically controversial East Asian Amitostigma alliance. Here, we present a framework nrITS tree of 235 accessions of Orchideae...

Data from: Hollows in living trees develop slowly but considerably influence the estimate of forest biomass

Zheng Zheng, Shubin Zhang, Carol Baskin, Jerry Baskin, Doug Schaefer, Xiaodong Yang & Lianyan Yang
The decomposition of wood inside living tree hollows influences forest structure and processes. Although the decomposition rate controls the formation of hollows, it has not previously been measured. In an old-growth subtropical montane evergreen broad-leaved forest in south-west China, we measured respiration rates of decaying wood inside living tree hollows, logs (downed tree trunks) and snags (standing dead trees) using infrared CO2 analysis. We compared stem radial growth rates to the horizontal expansion rates of...

Data from: Dispersal, niche, and isolation processes jointly explain species turnover patterns of nonvolant small mammals in a large mountainous region of China

Zhixin Wen, Qing Quan, Yuanbao Du, Lin Xia, Deyan Ge & Qisen Yang
Understanding the mechanisms that govern the spatial patterns of species turnover (beta diversity) has been one of the fundamental issues in biogeography. Species turnover is generally recognized as strong in mountainous regions, but the way in which different processes (dispersal, niche, and isolation) have shaped the spatial turnover patterns in mountainous regions remains largely unexplored. Here, we explore the directional and elevational patterns of species turnover for nonvolant small mammals in the Hengduan Mountains of...

Data from: Nutrient limitation of woody debris decomposition in a tropical forest: contrasting effects of N and P addition

Yao Chen, Emma J. Sayer, Zhian Li, Qifeng Mo, Yingwen Li, Yongzhen Ding, Jun Wang, Xiankai Lu, Jianwu Tang & Faming Wang
Tropical forests represent a major terrestrial store of carbon (C), a large proportion of which is contained in the soil and decaying organic matter. Woody debris plays a key role in forest C dynamics because it contains a sizeable proportion of total forest C. Understanding the factors controlling the decomposition of organic matter in general, and woody debris in particular, is hence critical to assessing changes in tropical C storage. We conducted a factorial fertilization...

Data from: Quantifying the factors affecting leaf litter decomposition across a tropical forest disturbance gradient

Ekananda Paudel, Gbadamassi G. O. Dossa, Marleen De Blécourt, Philip Beckschäfer, Jianchu Xu & Rhett D. Harrison
Deforestation and forest degradation are driving unprecedented declines in biodiversity across the tropics, and understanding the consequences of these changes for ecosystem functioning is essential for human well-being. Forest degradation and loss alter ecosystem functioning through changes in species composition and abiotic conditions. However, the consequences of these changes for heterospecific processes are often poorly understood. Leaf litter decomposition is a major source of atmospheric carbon and critical for carbon and nutrient cycling. Through a...

Data from: Reducing soil erosion by improving community functional diversity in semi-arid grasslands

Huoxing Zhu, Bojie Fu, Shuai Wang, Linhai Zhu, Lei Jiao, Cong Wang & Liwei Zhang
1. Great efforts have been made to control soil erosion by restoring plant communities in degraded ecosystems world-wide. However, soil erosion has not been substantially reduced mainly because current restoration strategies lead to large areas of mono-specific vegetation, which are inefficient in reducing soil erosion because of their simple canopy and root structure. Therefore, an advanced understanding of how community functional composition affects soil erosion processes, as well as an improved restoration scheme to reduce...

Data from: Accelerating plant DNA barcode reference library construction using herbarium specimens: improved experimental techniques

Chao Xu, Wenpan Dong, Shi Shuo, Cheng Tao, Changhao Li, Yanlei Liu, Ping Wu, Honghun Wu, Peng Gao & Shiliang Zhou
A well-covered reference library is crucial for successful identification of species by DNA barcoding. The biggest difficulty in building such a reference library is the lack of materials of organisms. Herbarium collections are potentially an enormous resource of materials. In this study, we demonstrate that it is likely to build such reference libraries using the reconstructed (self-primed PCR amplified) DNA from the herbarium specimens. We used 179 rosaceous specimens to test the effects of DNA...

Data from: High-throughput monitoring of wild bee diversity and abundance via mitogenomics

Min Tang, Chloe J. Hardman, Yinqiu Ji, Guanliang Meng, Shanlin Liu, Meihua Tang, Shenzhou Yang, Ellen D. Moss, Jiaxin Wang, Chenxue Yang, Catharine Bruce, Tim Nevard, Simon G. Potts, Xin Zhou, Douglas W. Yu & Meihua Tan
1. Bee populations and other pollinators face multiple, synergistically acting threats, which have led to population declines, loss of local species richness and pollination services, and extinctions. However, our understanding of the degree, distribution and causes of declines is patchy, in part due to inadequate monitoring systems, with the challenge of taxonomic identification posing a major logistical barrier. Pollinator conservation would benefit from a high-throughput identification pipeline. 2. We show that the metagenomic mining and...

Data from: Genetic structure and post-glacial expansion of Cornus florida L. (Cornaceae): integrative evidence from phylogeography, population demographic history, and species distribution modeling

Ashley Call, Yan-Xia Sun, Yan Yu, Peter B. Pearman, David T. Thomas, Robert Trigiano, Ignazio Carbone, Qiu-Yun Xiang, Robert N. Trigiano, Yan-Xia Sun & Qiu-Yun Jenny Xiang
Repeated global climatic cooling and warming cycles during the Pleistocene played a major role in the distribution and evolution of the Earth biota. Here, we integrate phylogeography, coalescent-based Bayesian estimation of demographic history, and species distribution modeling (SDM) to understand the genetic patterns and biogeography of the flowering dogwood, Cornus florida subsp. florida L., since the Last Glacial Maximum (LGM). Natural populations of the species are severely threatened by dogwood anthracnose. We genotyped 306 plants...

Data from: Yet another empty forest: considering the conservation value of a recently established tropical nature reserve

Rachakonder Sreekar, Kai Zhang, Jianchu Xu, Rhett D. Harrison & Rachakonda Sreekar
The primary approach used to conserve tropical biodiversity is in the establishment of protected areas. However, many tropical nature reserves are performing poorly and interventions in the broader landscape may be essential for conserving biodiversity both within reserves and at large. Between October 2010 and 2012, we conducted bird surveys in and around a recently established nature reserve in Xishuangbanna, China. We constructed a checklist of observed species, previously recorded species, and species inferred to...

Data from: Single-nucleotide polymorphism discovery and validation in high-density SNP array for genetic analysis in European white oaks

Camille Lepoittevin, Catherine Bodénès, Emilie Chancerel, Laure Villate, Tiange Lang, Isabelle Lesur, Christophe Boury, François Ehrenmann, Diana Zelenika, Anne Boland, Céline Besse, Pauline Garnier-Géré, Christophe Plomion & Antoine Kremer
An Illumina Infinium SNP genotyping array was constructed for European white oaks. Six individuals of Quercus petraea and Q. robur were considered for SNP discovery using both previously obtained Sanger sequences across 676 gene regions (1371 in vitro SNPs) and Roche 454 technology sequences from 5112 contigs (6542 putative in silico SNPs). The 7913 SNPs were genotyped across the six parental individuals, full-sib progenies (one within each species and two interspecific crosses between Q. petraea...

Data from: Soil acidification exerts a greater control on soil respiration than soil nitrogen availability in grasslands subjected to long-term nitrogen enrichment

Dima Chen, Jianjun Li, Zhichun Lan, Shuijin Hu & Yongfei Bai
Terrestrial ecosystems worldwide are receiving increasing amounts of biologically reactive nitrogen (N) as a consequence of anthropogenic activities. This intended or unintended fertilization can have a wide-range of impacts on biotic communities and hence on soil respiration. Reduction in below-ground carbon (C) allocation induced by high N availability has been assumed to be a major mechanism determining the effects of N enrichment on soil respiration. In addition to increasing available N, however, N enrichment causes...

Data from: Barcoding the kingdom Plantae: new PCR primers for ITS regions of plants with improved universality and specificity

Tao Cheng, Chao Xu, Li Lei, Changhao Li, Yu Zhang & Shiliang Zhou
The internal transcribed spacer (ITS) of nuclear ribosomal DNA is one of the most commonly used DNA markers in plant phylogenetic and DNA barcoding analyses, and it has been recommended as a core plant DNA barcode. Despite this popularity, the universality and specificity of PCR primers for the ITS region are not satisfactory, resulting in amplification and sequencing difficulties. By thoroughly surveying and analysing the 18S, 5.8S and 26S sequences of Plantae and Fungi from...

Data from: Functional correlations between specific leaf area and specific root length along a regional environmental gradient in Inner Mongolia grasslands

Junhui Cheng, Pengfei Chu, Dima Chen & Yongfei Bai
Among above- and belowground traits, specific leaf area (SLA, cm2 g−1) and specific root length (SRL, m g−1) are the two key traits reflecting species resource acquisition strategies. However, patterns of variation in SLA and SRL have rarely been examined simultaneously across evolutionary history and environmental gradients, and the SLA-SRL relationship is still controversial on several grounds. We examined the inter- and intraspecific variations in SLA and SRL of different root branching orders and the...

Data from: Mito-nuclear phylogeography of the cyprinid fish Gymnodiptychus dybowskii in the arid Tien Shan region of Central Asia

Guogang Li, Zuogang Peng, Renyi Zhang, Yongtao Tang, Chao Tong, Chenguang Feng, Cunfang Zhang & Kai Zhao
We evaluated the phylogeography and historical demography of the cyprinid fish Gymnodiptychus dybowskii (subfamily Schizothoracinae) across three northern Qinghai-Tibetan Plateau (QTP) river systems in the Tien Shan range: the Kaidu River, Ili River and Junggar Basin. Results from both mtDNA (16S rRNA and Cyt b) and nuDNA (RAG-2) resolved three reciprocally monophyletic clades, one in each of the three river basins. Estimated divergence times (highest posterior density (HPD) 2.4–3.7 Mya) are consistent with the hypothesis...

Data from: C:N:P stoichiometry of Artemisia species and close relatives across northern China: unraveling effects of climate, soil and taxonomy

Xuejun Yang, Zhenying Huang, Keliang Zhang & Johannes Hans C. Cornelissen
1. Carbon (C), nitrogen (N) and phosphorus (P) stoichiometries play critical roles in the function and structure of ecosystems by affecting important ecological processes. Yet, most studies to date have concentrated on foliar stoichiometry of phylogenetically distantly related species. 2. Here, we hypothesized that (i) plant stoichiometry of closely related species still shows biogeographic patterns because of the geographic patterns of abiotic environment at the regional scale and (ii) even related species still differ strongly...

Data from: Phylogeographic structure and deep lineage diversification of the red alga Chondrus ocellatus Holmes in the Northwest Pacific

Zi-Min Hu, Jing-Jing Li, Zhong-Min Sun, Jung-Hyun Oak, Jie Zhang, Pablo Fresia, W. Stewart Grant & De-Lin Duan
A major goal of phylogeographic analysis using molecular markers is to understand the ecological and historical variables that influence genetic diversity within a species. Here, we used sequences of the mitochondrial Cox1 gene and nuclear internal transcribed spacer to reconstruct its phylogeography and demographic history of the intertidal red seaweed Chondrus ocellatus over most of its geographical range in the Northwest Pacific. We found three deeply separated lineages A, B and C, which diverged from...

Data from: Population genetic structure of Oryza rufipogon and O. nivara: implications for the origin of O. nivara

Rong Liu, Xiao-Ming Zheng, Lian Zhou, Hai-Fei Zhou & Song Ge
Ecological speciation plays a primary role in driving species divergence and adaptation. Oryza rufipogon and Oryza nivara are two incipient species at the early stage of speciation with distinct differences in morphology, life history traits and habitat preference, and therefore provide a unique model for the study of ecological speciation. However, the population genetic structure of the ancestral O. rufipogon has been controversial despite substantial study, and the origin of the derivative O. nivara remains...

Data from: Does mixed-species flocking influence how birds respond to a gradient of land-use intensity?

Christos Mammides, Jin Chen, Uromi Manage Goodale, Sarath Wimalabandara Kotagama, Swati Sidhu & Eben Goodale
Conservation biology is increasingly concerned with preserving interactions among species such as mutualisms in landscapes facing anthropogenic change. We investigated how one kind of mutualism, mixed-species bird flocks, influences the way in which birds respond to different habitat types of varying land-use intensity. We use data from a well-replicated, large-scale study in Sri Lanka and the Western Ghats of India, in which flocks were observed inside forest reserves, in ‘buffer zones' of degraded forest or...
