Data from: The differential contributions of herkogamy and dichogamy as mechanisms of avoiding self-interference in four self-incompatible Epimedium species

Xiao-Xia Li, Yuan Zou, Chang-Long Xiao, Robert W. Gituru, You-Hao Guo, Chun-Feng Yang, X.-X. Li, C.-L. Xiao, Y.-H. Guo & C.-F. Yang
Self-interference is one of the most important selective forces in shaping floral evolution. Herkogamy and dichogamy both can achieve reductions in the extent of self-interference, but they may have different roles in minimizing self-interference in a single species. We used four self-incompatible Epimedium species to explore the roles of herkogamy and dichogamy in avoiding self-interference and to test the hypothesis that herkogamy and dichogamy may be separated and become selected preferentially in the taxa. Two...

Data from: Turtle embryos move to optimal thermal environments within the egg

Bo Zhao, Teng Li, Richard Shine, Wei-Guo Du & W.-G. Du
A recent study demonstrated that the embryos of soft-shelled turtles can reposition themselves within their eggs to exploit locally warm conditions. In the current paper, we ask whether turtle embryos actively seek out optimal thermal environments for their development, as do post-hatching individuals. Specifically, (1) do reptile embryos move away from dangerously-high temperatures, as well as towards warm temperatures? and (2) is such embryonic movement due to active thermoregulation, or (more simply) to passive embryonic...

Data from: Linking the evolution of body shape and locomotor biomechanics in bird-line archosaurs

Vivian Allen, Karl T. Bates, Zhiheng Li & John R. Hutchinson
Locomotion in living birds (Neornithes) has two remarkable features: feather-assisted flight, and the use of unusually crouched hindlimbs for bipedal support and movement. When and how these defining functional traits evolved remains controversial. However, the advent of computer modelling approaches and the discoveries of exceptionally preserved key specimens now make it possible to use quantitative data on whole-body morphology to address the biomechanics underlying this issue. Here we use digital body reconstructions to quantify evolutionary...

Data from: Complete chloroplast genome of the genus Cymbidium: lights into the species identification, phylogenetic implications and population genetic analyses

Jun-Bo Yang, Min Tang, Hong-Tao Li, Zhi-Rong Zhang & De-Zhu Li
Background: Cymbidium orchids, including some 50 species, are the famous flowers, and they possess high commercial value in the floricultural industry. Furthermore, the values of different orchids are great differences. However, species identification is very difficult. To a certain degree, chloroplast DNA sequence data are a versatile tool for species identification and phylogenetic implications in plants. Different chloroplast loci have been utilized for evaluating phylogenetic relationships at each classification level among plant species, including at...

Data from: A new specimen of large-bodied basal enantiornithine Bohaiornis from the early Cretaceous of China and the inference of feeding ecology in Mesozoic birds

Zhiheng Li, Zhonghe Zhou, Min Wang & Julia A. Clarke
A new specimen of Bohaiornis guoi from the Jiufotang Formation, comprising a nearly complete skeleton, sheds light on enantiornithine morphological variation and ecological specialization. The new specimen was collected from near Lamadong Village in Liaoning Province, which is the same area where the sub-adult holotype specimen was reported. It provides new information on the cranial and pectoral girdle anatomy of the species, e.g., broad nasal, strikingly robust acromion, medially curved acrocoracoid process. In contrast to...

Data from: Evidence of a component Allee effect driven by predispersal seed predation in a plant (Pedicularis rex, Orobanchaceae)

Jing Xia, ShiGuo Sun & GuiHua Liu
A small or sparse population may suffer a reduction in fitness due to Allee effects. Here we explored effects of plant density on pollination, reproduction and predation in the alpine herb Pedicularis rex over two years. We did not detect a significant difference in pollination rate or fecundity (fruit set and initial seed set) before predation between sparse and dense patches in either year, indicating no pollination-driven Allee effect. However, dense patches experienced significantly fewer...

Data from: Discriminating plants using the DNA barcode rbcLb: an appraisal based on a large data set

Wenpan Dong, Tao Cheng, Changhao Li, Chao Xu, Ping Long, Chunming Chen & Shiliang Zhou
The ideal DNA barcode for plants remains to be discovered, and the candidate barcode rbcL has been met with considerable skepticism since its proposal. In fact, the variability within this gene has never been fully explored across all plant groups from algae to flowering plants, and its performance as a barcode has not been adequately tested. By analyzing all of the rbcL sequences currently available in GenBank, we attempted to determine how well a region...

Data from: Genetic diversity, demographical history and conservation aspects of the endangered yew tree Taxus contorta (syn. Taxus fuana) in Pakistan

Ram C. Poudel, Michael Möller, De-Zhu Li, Amin Shah & Lian-Ming Gao
Western Himalayan yew (Taxus contorta Griffith, synonym T. fuana Nan Li & R.R. Mill), one of the highly prized tree species for its anticancer properties is experiencing severe reduction in populations across its range in Pakistan. We examined a chloroplast DNA region (trnL-F) and ten nuclear microsatellite loci variations among seven populations to investigate the levels of genetic diversity and demographical history of T. contorta in Pakistan. Low haplotype diversity (HT = 0.182), moderate level...

Data from: Microsatellite evidence for high frequency of multiple paternity in the marine gastropod Rapana venosa

Dongxiu Xue, Tao Zhang, Liu Jin-Xian & Jin-Xian Liu
Background: Inferring of parentage in natural populations is important in understanding the mating systems of a species, which have great effects on its genetic structure and evolution. Muricidae, a large group (approximately 1,600 species) of marine gastropods, are poorly investigated in patterns of multiple paternity and sperm competition based on molecular techniques. The veined Rapa whelk, Rapana venosa, a commercially important muricid species with internal fertilization, is an ideal species to study the occurrence and...

Data from: Identification of SNP markers for inferring phylogeny in temperate bamboos (Poaceae: Bambusoideae) using RAD sequencing

Xue Qin Wang, Lei Zhao, Deren A. R. Eaton, De Zhu Li & Zhen Hua Guo
Phylogenetic relationships among temperate species of bamboo are difficult to resolve, owing to both the challenge of detecting sufficiently variable markers and their polyploid history. Here, we use restriction site–associated DNA sequencing to identify candidate loci with fixed allelic differences segregating between and within two temperate species of bamboos: Arundinaria faberi and Yushania brevipaniculata. Approximately 27 million paired-end sequencing reads were generated across four samples. From pooled data, we assembled 67 685 and 70 668...

Data from: Speciation of two desert poplar species triggered by Pleistocene climatic oscillations

Juan Wang, Thomas Källman, Jianquan Liu, Qiuhong Guo, Yuxia Wu, Kao Lin & Martin Lascoux
Despite the evidence that the Pleistocene climatic fluctuations have seriously affected the distribution of intraspecific diversity, less is known on its impact on interspecific divergence. In this study, we aimed to test the hypothesis that the divergence of two desert poplar species Populus euphratica Oliv. and P. pruinosa Schrenk. occurred during the Pleistocene. We sequenced 11 nuclear loci in 60 individuals from the two species to estimate the divergence time between them and to test...

Data from: Climate warming and the potential extinction of fig wasps, the obligate pollinators of figs

Alexander G. R. Goh, Richard T. Corlett & Nanthinee Jevanandam
Figs (Ficus) have a reciprocally obligate mutualism with tiny, short-lived (1–2 days) fig wasps (Agaonidae). The small size and short life of these pollinators is expected to make them more vulnerable to climate change than their larger and longer-lived hosts. We experimentally tested the thermal tolerances of four species of adult female fig wasps from equatorial Singapore. The results suggest that an increase of ≥ 3oC above the current temperatures experienced across much of the...

Data from: Restricted gene flow within and between rapidly diverging neotropical plant species

Kathleen M. Kay & Yann Surget-Groba
Speciation involves the evolution of traits and genetic differences that contribute to reproductive isolation and the cessation of gene flow, and studying closely related species and divergent populations gives insight into how these phenomena proceed. Here, we document patterns of gene flow within and between two members of a rapid Neotropical species radiation, Costus pulverulentus and Costus scaber (Costaceae). These species co-occur in the tropical rainforest and share pollinators, but are reproductively isolated by a...

Data from: Factors determining forest diversity and biomass on a tropical volcano, Mt. Rinjani, Lombok, Indonesia

Gbadamassi G. O. Dossa, Ekananda Paudel, Junichi Fujinuma, Haiying Yu, Wanlop Chutipong, Yuan Zhang, Sherryl Paz, Rhett D. Harrison & Nathan G. Swenson
Tropical volcanoes are an important but understudied ecosystem, and the relationships between plant species diversity and compositional change and elevation may differ from mountains created by uplift, because of their younger and more homogeneous soils. We sampled vegetation over an altitudinal gradient on Mt. Rinjani, Lombok, Indonesia. We modeled alpha- (plot) and beta- (among plot) diversity (Fisher’s alpha), compositional change, and biomass against elevation and selected covariates. We also examined community phylogenetic structure across the...

Data from: Shifting baselines on a tropical forest frontier: extirpations drive declines in local ecological knowledge

Zhong Kai, Teoh Shu Woan, Li Jie, Eben Goodale, Kaoru Kitajima, Robert Bagchi, Rhett D. Harrison & Zhang Kai
The value of local ecological knowledge (LEK) to conservation is increasingly recognised, but LEK is being rapidly lost as indigenous livelihoods change. Biodiversity loss is also a driver of the loss of LEK, but quantitative study is lacking. In our study landscape in SW China, a large proportion of species have been extirpated. Hence, we were interested to understand whether species extirpation might have led to an erosion of LEK and the implications this might...

Data from: N balance and cycling of Inner Mongolia typical steppe - a comprehensive case study of grazing effects

Marcus Giese, Holger Brueck, Yingzhi Gao, Shan Lin, Markus Steffens, Ingrid Kögel-Knabner, Thomas Glindemann, Andreas Susenbeth, Friedhelm Taube, Klaus Butterbach-Bahl, Xunhua Zheng, Carsten Hoffmann, Yongfei Bai & Xingguo Han
Increasing grazing pressure and climate change affect nitrogen (N) dynamics of grassland ecosystems in the Eurasian Steppe belt with unclear consequences for future delivery of essential services such as forage production, C sequestration, and diversity conservation. The identification of key processes responsive to grazing is crucial to optimize grassland management. In this comprehensive case study of a Chinese typical steppe, we present an in-depth analysis of grazing effects on N dynamics including the balance of...

Data from: Population size and time since island isolation determine genetic diversity loss in insular frog populations

Supen Wang, Wei Zhu, Xu Gao, Xianping Li, Yan Shaofei, Xuan Liu, Ji Yang, Zengxiang Gao, Yiming Li & Shaofei Yan
Understanding the factors that contribute to loss of genetic diversity in fragmented populations is crucial for conservation measurements. Land-bridge archipelagoes offer ideal model systems for identifying the long-term effects of these factors on genetic variations in wild populations. In this study, we used 9 microsatellite markers to quantify genetic diversity and differentiation of 810 pond frogs (Pelophylax nigromaculataus) from 24 islands of the Zhoushan Archipelago and 3 sites on nearby mainland China and estimated the...

Data from: Local genetic structure in the critically endangered, cave-associated perennial herb Primulina tabacum (Gesneriaceae)

Zheng-Feng Wang, Hai Ren, Zhong-Chao Li, Qian-Mei Zhang, Kai-Ming Liang, Wan-Hui Ye & Zhang-Ming Wang
The local spatial genetic structures of cave-associated plants are seldom studied. Given that these plants are mainly confined to small areas in and around the entrances of caves, we hypothesized that they might lack genetic structures at local scales. To test this hypothesis, we sampled two large populations (named D and T) of a critically endangered perennial herb, Primulina tabacum, which is endemic to karst caves in southern China. We analysed nine microsatellite loci and...

Data from: Independent domestications of cultivated tree peonies from different wild peony species

Jun-Hui Yuan, Amandine Cornille, Tatiana Giraud, Fang-Yun Cheng & Yong-Hong Hu
An understanding of plant domestication history provides insights into general mechanisms of plant adaptation and diversification and can guide breeding programs that aim to improve cultivated species. Cultivated tree peonies (genus Paeonia L.) are among the most popular ornamental plants in the world, yet the history of their domestication is still unresolved. Here, we explored whether the domestication in China of historically cultivated peonies, i.e., the common and flare cultivated tree peonies, was a single...
