Horizontally acquired cysteine synthase genes undergo functional divergence in lepidopteran herbivores

Yinghui Li & Huabing Wang
Horizontal gene transfer (HGT) plays an important role in evolutionary processes as organisms adapt to their environments, and now cases of gene duplication after HGT in eukaryotes are emerging at an increasing rate. However, the fate and roles of the duplicated genes over time in eukaryotes remain unclear. Here we conducted a comprehensive analysis of the evolution of cysteine synthase (CYS) in lepidopteran insects. Our results indicate that HGT-derived CYS genes are widespread and have...

Katherine Angier, Richard Rabideau-Childers, Brendan Dean, Meghan Blumstein, Walker Darling, Annina Kennedy-Yoon, Clayton Ziemke, Christian Perez-Martinez, Donghao Wu, Wenqing Ye, Inam Yekwayo, Duncan Kimuyu, Dino Martins & Naomi Pierce
1. Fire is a major selective force on arid grassland communities, favoring traits such as the smoke-induced seed germination response seen in a wide variety of plant species. However, little is known about the relevance of smoke as a cue for plants beyond the seedling stage. 2. We exposed a fire-adapted savanna tree, Vachellia (=Acacia) drepanolobium, to smoke and compared nutrient concentrations in leaf and root tissues to unexposed controls. Experiments were performed on three...

Soil chemistry determines whether defensive plant secondary metabolites promote or suppress herbivore growth

Lingfei Hu, Zhenwei Wu, Christelle A.M. Robert, Matthias Erb, Jianming Xu, Xiao Ouyang, Tobias Züst & Adrien Mestrot
Plant secondary (or specialized) metabolites mediate important interactions in both the rhizosphere and the phyllosphere. If and how such compartmentalized functions interact to determine plant-environment interactions is not well understood. Here, we investigated how the dual role of maize benzoxazinoids as leaf defenses and root siderophores shapes the interaction between maize and a major global insect pest, the fall armyworm. We find that benzoxazinoids suppress fall armyworm growth when plants are grown in soils with...

Long-term dietary flavonoid intake and subjective cognitive decline in US men and women

Tian-Shin Yeh, Changzheng Yuan, Alberto Ascherio, Bernard Rosner, Walter Willett & Deborah Blacker
Objective: To prospectively examine the associations between long-term dietary flavonoids and subjective cognitive decline (SCD). Methods: We followed 49,493 women from the Nurses’ Health Study (NHS) (1984-2006) and 27,842 men from the Health Professionals Follow-up Study (HPFS) (1986-2002). Poisson regression was used to evaluate the associations between dietary flavonoids (flavonols, flavones, flavanones, flavan-3-ols, anthocyanins, polymeric flavonoids, and proanthocyanidins) and subsequent SCD. For the NHS, long-term average dietary intake was calculated from seven repeated food frequency...

Yingying Ni, Teng Yang, Yuying Ma, Kaoping Zhang, Pamela Soltis, Douglas Soltis, Jack Gilbert, Yunpeng Zhao, Chengxin Fu & Haiyan Chu
Aim: There have been numerous studies of forest-soil microbial biogeography, but an integrated view of edaphic factors, plant, climatic factors, and geographic distance in determining the variation of bacterial community and assembly processes remains unclear at large spatial scales. Here, we analyzed the factors affecting the biogeographic pattern and assembly processes of soil bacterial communities under 58 tree species in five natural mountain forests. Location: Eastern China. Major taxa studied: Bacterial communities. Methods: Hierarchical partitioning...

Sampling biases shape our view of the natural world

Alice Hughes, Keping Ma, Mark Costello, John Waller, Pieter Provoost, Qinmin Yang, Chaodong Zhu, Huijie Qiao & Michael Orr
Spatial patterns of biodiversity are inextricably linked to their collection methods, yet no synthesis of bias patterns or their consequences exists. As such, views of organismal distribution and the ecosystems they make up may be incorrect, undermining countless ecological and evolutionary studies. Using 742 million records of 374,900 species, we explore the global patterns and impacts of biases related to taxonomy, accessibility, ecotype, and data type across terrestrial and marine systems. Pervasive sampling and observation...

Yang Li, Zhanguo Li, Zhen Liu, Shitong Han, Sanping Zhao, Keping Yan & Anna Zhu
This paper demonstrated the effects and influencing factors in degrading aniline by gaseous streamer corona plasma along water surface under different discharging gas atmospheres. For aniline with an initial concentration of 100 mg/L, the degradation was fastest when the reactor was not ventilated, and degradation rate is 98.5% under 7.5 min treatment. While the degradation was slowest when Ar was ventilated, the degradation rate is 98.6% after treated for 60 min. Some active particles were...

Microsatellite data of 21 EST-SSR loci from all 503 Emmenopterys henryi samples

Wuqin Xu
Aim: Several hypotheses are available to predict change in genetic diversity at expanding peripheral ranges. However, empirical evidence to test predictions of the centre-periphery hypothesis (CPH) at contracting range limits is scarce. To address this issue, we assessed spatial patterns of genetic variation, effective population size, and contemporary and historical gene flow in a widespread, Tertiary relict tree species from subtropical China. Location: Warm-temperate deciduous forests of subtropical China. Taxon:Emmenopterys henryi (Rubiaceae) Methods: We applied...

Revisiting of Carex sect. Confertiflorae s.l. (Cyperaceae): new data from molecular and morphological evidence and first insights on Carex biogeography in East Asia.

Yi-Fei Lu, Xiao-Feng Jin, Hiroshi Ikeda, Okihito Yano, Carmen Benítez Benítez, Wei-Jie Chen, Yong-Di Liu, Pedro Jiménez-Mejías & Ming-Jian Yu
Carex sect. Confertiflorae s.l., contains ca. 40 species and diverse in E Asia. It has one of the most unstable delimitations in the literature, and the section was proposed to split into two sections up to five different ones. Recent phylogenetic reconstructions showed Confertiflorae s.l. not to be monophyletic. In this study we investigate the phylogenetic structure, morphological affinities, and biogeographic history of sect. Confertiflorae s.l. We performed a taxon-based approach to explore the morphological...

Island area, not isolation, drives taxonomic, phylogenetic and functional diversity of ants on land-bridge islands

Yuhao Zhao, Robert Dunn, Haonan Zhou, Xingfeng Si & Ping Ding

Location: Thousand Island Lake, Zhejiang, China, created by dam construction in 1959. Taxon: Ants. Methods: We sampled ants on 33 islands, built a species-level phylogenetic tree and measured five morphological traits of all species collected to estimate taxonomic, phylogenetic, and functional diversity. We used multiple...

Dissecting incongruence between concatenation- and quartet-based approaches in phylogenomic data

Xing-Xing Shen, Jacob Steenwyk & Antonis Rokas
Topological conflict or incongruence is widespread in phylogenomic data. Concatenation- and coalescent-based approaches often result in incongruent topologies, but the causes of this conflict can be difficult to characterize. We examined incongruence stemming from conflict between likelihood-based signal (quantified by the difference in gene-wise log likelihood score or ΔGLS) and quartet-based topological signal (quantified by the difference in gene-wise quartet score or ΔGQS) for every gene in three phylogenomic studies in animals, fungi, and plants,...

Ke Cao, Richard Condit, Xiangcheng Mi, Lei Chen, Wubing Xu, David F. R. P. Burslem, Chunrong Cai, Min Cao, Li-Wan Chang, Chengjin Chu, Hu Du, Sisira Ediriweera, C. S. V. Gunatilleke, I. U. A. N. Gunatilleke, Zhanqing Hao, Jinbo Li, Guangze Jin, Buhang Li, Yankun Liu, Yide Li, Michael J. O'Brien, Xiujuan Qiao, Hongwei Ni, Guochun Shen, Xihua Wang … & Jens-Christian Svenning
The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall local species richness (gamma diversity) remains hotly debated. Previous studies that failed to resolve the issue suffered from a well-known tendency for small samples in areas with high gamma-diversity to have inflated measures of beta-diversity. We provide here a novel analytical test, using beta-diversity metrics...

Gabor Pozsgai, Gabor Lövei, Liette Vasseur, Geoff Gurr, Péter Batáry, Janos Korponai, Nick Littlewood, Jian Liu, Arnold Móra, John Obrycki, Olivia Reynolds, Jenni Stockan, Heather VanVolkenburg, Jie Zhang, Wenwu Zhou & Minsheng You
1. Repeatability is the cornerstone of science and it is particularly important for systematic reviews. However, little is known on how researchers’ choice of database and search platform influence the repeatability of systematic reviews. Here, we aim to unveil how the computer environment and the location where the search was initiated from influence hit results. 2. We present a comparative analysis of time-synchronized searches at different institutional locations in the world, and evaluate the consistency...

Non-linear thresholds in the effects of island area on functional diversity in woody plant communities

Aiying Zhang, Shilu Zheng, Raphael K. Didham, Robert D. Holt & Mingjian Yu
1. Threshold non-linearities in the relationship between island area and species richness can result in dramatic declines in richness with a seemingly small decline in area near the threshold. What is not known, is whether threshold declines in richness are also accompanied by non-linear changes in functional trait space and non-random shifts of trait group composition in response to declining area. 2. Plant species richness was recorded, and four functional diversity (FD) indices calculated based...

Evolutionary changes in an invasive plant support the defensive role of plant volatiles

Carlos Bustos-Segura, Tiantian Lin, Klaas Vrieling, Diane Laplanche, Peter G. L. Klinkhamer, Yonggen Lou, Leon Bekooy, Thomas Degen, Ted Turlings & Gaylord Desurmont
It is increasingly evident that plants interact with their outside world through the production of volatile organic compounds, but whether the volatiles have evolved to serve in plant defense is still a topic of considerable debate. Unharmed leaves constitutively release small amounts of volatiles, but when the leaves are damaged by herbivorous arthropods, they emit substantially more volatiles. These herbivore-induced plant volatiles (HIPVs) attract parasitoids and predators that kill insect herbivores, and this can benefit...

Disentangling biotic and abiotic drivers of intraspecific trait variation in woody plant seedlings at forest edges

Shilu Zheng, Bruce Webber, Raphael Didham, Chun Chen & Mingjian Yu
In fragmented forests, edge effects can drive intraspecific variation in seedling performance that influences forest regeneration and plant composition. However, few studies have attempted to disentangle the relative biotic and abiotic drivers of intraspecific variation in seedling performance. In this study, we carried out a seedling transplant experiment with a factorial experimental design on three land-bridge islands in the Thousand Island Lake, China, using four common native woody plant species. At different distances from the...

β diversity among ant communities on fragmented habitat islands: the roles of species trait, phylogeny and abundance

Yuhao Zhao, Nathan Sanders, Juan Liu, Tinghao Jin, Haonan Zhou, Ruisen Lu, Ping Ding & Xingfeng Si
Habitat loss and fragmentation reduce biodiversity and alter species composition in local communities. β diversity describes the variation in species composition between or among communities in fragmented landscapes and has two components: species turnover and nestedness. In this study, we assessed β diversity of ant assemblages on 24 island fragments in the Thousand Island Lake, China. We constructed a species-level phylogenetic tree and measured five morphological traits of all ant species captured. We then assessed...

Data for drainage capillary pressure distribution and fluid displacement in a heterogeneous laminated sandstone

Qingyang Lin, Branko Bijeljic & Martin Blunt
We applied three-dimensional X-ray microtomography to image a capillary drainage process (0-1000 kPa) in a cm-scale heterogeneous laminated sandstone containing three distinct regions with different pore sizes to study the capillary pressure. We used differential imaging to distinguish solid, macro pore and five levels of sub-resolution pore phases associated with each region. The brine saturation distribution was computed based on average CT values. The non-wetting phase displaced the wetting phase in order of pore size...
