Data from: Exacerbated grassland degradation and desertification in Central Asia during 2000-2014

Grassland degradation and desertification is a complex process, including both state conversion (e.g., grasslands to deserts) and gradual within-state change (e.g., greenness dynamics). Existing studies hardly separated the two components and analyzed it as a whole based on time series vegetation index data, which however cannot provide a clear and comprehensive picture for grassland degradation and desertification. Here we proposed an integrated assessment strategy, by considering both state conversion and within-state change of grasslands, to...

Data from: Clinical efficacy of implantation of toric intraocular lenses with different incision positions: a comparative study of steep-axis incision and non-steep-axis incision

Wenwen He, Xiangjia Zhu, Yu Du, Jin Yang & Yi Lu
Background: To compare the clinical outcomes after implantation of AcrySof Toric IOLs with different clear corneal incisions. Methods: Sixty cataract patients with regular corneal astigmatism who underwent phacoemulsification combined with implantation of an AcrySof Toric IOL were enrolled. They were divided into two groups according to the position of the clear corneal incision: steep-axis and non-steep-axis. Main outcome measurements included visual acuity, residual astigmatism and changes of corneal astigmatism 3 months postoperatively. Deviation of IOL...

Gnetophytes are an enigmatic gymnosperm lineage comprising three genera, Gnetum, Welwitschia and Ephedra, which are morphologically distinct from all other seed plants. Their distinctiveness has triggered much debate as to their origin, evolution and phylogenetic placement among seed plants. To increase our understanding of the evolution of gnetophytes, and their relation to other seed plants, we report here a high-quality draft genome sequence for Gnetum montanum, the first for any gnetophyte. By using a novel...

Data from: Estimating the parameters of background selection and selective sweeps in Drosophila in the presence of gene conversion

José Luis Campos, Lei Zhao & Brian Charlesworth
We used whole-genome resequencing data from a population of Drosophila melanogaster to investigate the causes of the negative correlation between the within-population synonymous nucleotide site diversity (πS) of a gene and its degree of divergence from related species at nonsynonymous nucleotide sites (KA). By using the estimated distributions of mutational effects on fitness at nonsynonymous and UTR sites, we predicted the effects of background selection at sites within a gene on πS and found that...

Data from: Phylogeography of Sophora moorcroftiana supports Wu’s hypothesis on the origin of Tibetan alpine flora

Shanmei Cheng, Qiang La, Fan Lu, Takahiro Yonezawa, Ganqiang Yin, Zhiping Song, Yuguo Wang, Ji Yang, Wenju Zhang & La Qiong
Wu hypothesized that the Tibetan flora originated mostly from the paleotropical Tertiary flora in the Hengduan Mountains by adapting to the cold and arid environments associated with the strong uplift of the Qinghai-Tibet Plateau (QTP). Here, we combine the phylogeographic history of Sophora moorcroftiana with that of S. davidii to explore the speciation of S. moorcroftiana to test this hypothesis. We collected 151 individuals from 17 populations and sequenced two chloroplast fragments and the internal...

Data from: Economic costs and health-related quality of life for hand, foot and mouth disease (HFMD) patients in China

Yaming Zheng, Mark Jit, Joseph T. Wu, Juan Yang, Kathy Leung, Qiaohong Liao & Hongjie Yu
Background: Hand, foot and mouth disease (HFMD) is a common illness in China that mainly affects infants and children. The objective of this study is to assess the economic cost and health-related quality of life associated with HFMD in China. Method: A telephone survey of caregivers were conducted in 31 provinces across China. Caregivers of laboratory-confirmed HFMD patients who were registered in the national HFMD enhanced surveillance database during 2012-2013 were invited to participate in...
