Field evidence reveals conservative water use of poplars under high aerosol conditions in Beijing

Bin Wang, Zhenhua Wang, Chengzhang Wang, Xin Wang, Jing Li, Zhou Jia, Ping Li, Jin Wu, Min Chen & Lingli Liu
Anthropogenic aerosols could alter multiple meteorological processes such as radiation regime and air temperature, thereby modifying plant transpiration. However, the lack of field observations at the leaf- and plant-level hinders our ability to understand how aerosols could affect plant water use. Aerosol concentrations in northern China fluctuates periodically over a wide range. Taking advantage of this unique natural experiment opportunity, we conducted a full series of supporting physiological and environmental measurements to explore aerosols' effect...

Spatial patterns and ecological drivers of soil nematode β-diversity in natural grasslands vary among vegetation types and trophic position

Dan Xiong, Cunzheng Wei, Xugao Wang, Xiaotao Lü, Shuai Fang, Yingbin Li, Xiaobo Wang, Wenju Liang, Xingguo Han, T. Martijn Bezemer & Qi Li
1. Understanding biogeographic patterns of community assemblages is a core objective in ecology, but for soil communities these patterns are poorly understood. To understand the spatial patterns and underlying mechanisms of β-diversity in soil communities, we investigated the β-diversity of soil nematode communities along a 3200 km transect across semi-arid and arid grasslands. 2. Spatial turnover and nested-resultant are the two fundamental components of β-diversity, which have been attributed to various processes of community assembly....

Multisensory integration facilitates perceptual restoration of an interrupted call in frog

Bicheng Zhu, Yue Yang, Ya Zhou, Ke Deng, Tongliang Wang, Jichao Wang, Yezhong Tang, Michael J. Ryan & Jianguo Cui
How to render an interrupted sound as a complete signal is a common challenge faced by human and non-human animals during vocal communication. Using video and audio playbacks, we showed that neither inserting white noise into the silent gap of an interrupted call nor displaying the dynamic inflating-deflating vocal sac in that same gap restored attraction of the call equivalent to that of a complete call. Simultaneously presenting a dynamic vocal sac along with white...

Genome-wide investigation and transcriptional profiling of the oxidosqualene cyclase (OSC) genes in wheat (Triticum aestivum L.)

Changfeng Guo, Xingchen Xiong, Huan Dong & Xiaoquan Qi
Triterpene scaffolds are cyclized by differential functional genes of the oxidosqualene cyclase (OSC) gene family, which are widely present in plant species. Thirty-nine OSCs genes were identified from the hexaploid bread wheat (Triticum aestivum L.) genome. The gene structure organization and the distribution of conserved motifs of OSCs gene family revealed that the TaOSC proteins are highly conserved. By phylogenetic analysis, all OSC proteins from wheat and other cereal crops were clustered into eleven subfamilies...

Data from: Latitudinal embryonic thermal tolerance and plasticity shape the vulnerability of oviparous species to climate change

Bao-Jun Sun, Liang Ma, Yang Wang, Chun-Rong Mi, Lauren Buckley, Ofir Levy, Hong-Liang Lu & Wei-Guo Du
Heat tolerance at the immobile embryonic stage is expected to be critical in determining species vulnerability to climate change. However, how the mean and developmental plasticity of embryonic heat tolerance vary geographically, and how these geographic variations affect species’ vulnerability under climate change remain unknown. We experimentally determined the mean and developmental plasticity of embryonic acute heat tolerance (EAHT, i.e., heat shock temperature at which embryonic heartbeats ceased) for three latitudinally-distributed populations of an oviparous...

Biogeographic diversification of Eranthis (Ranunculaceae) reflects the geological history of the three great Asian plateaus

Kun-Li Xiang, Andrey S. Erst, Jian Yang, Huan-Wen Peng, Rosa Del C. Ortiz, Florian Jabbour, Tatyana V. Erst & Wei Wang
The evolutionary history of organisms with poor dispersal abilities usually parallels geological events. Collisions of the Indian and Arabian plates with Eurasia greatly changed Asian topography and affected regional and global climate as well as biotic evolution. However, the geological evolution of Asia related to these two collisions remains debated. Here, we used Eranthis, an angiosperm genus with poor seed dispersal ability and a discontinuous distribution across Eurasia , to shed light on the orogenesis...

Fat storage influences fasting endurance more than body size in an ungulate

L. Monica Trondrud, Gabriel Pigeon, Elżbieta Król, Steve Albon, Alina L. Evans, Walter Arnold, Catherine Hambly, R. Justin Irvine, Erik Ropstad, Audun Stien, Vebjørn Veiberg, John R. Speakman & Leif Egil Loe
1. The fasting endurance hypothesis (FEH) predicts strong selection for large body size in mammals living in environments where food supply is interrupted over prolonged periods of time. The Arctic is a highly seasonal and food restricted environment, but contrary to predictions from the FEH, empirical evidence shows that Arctic mammals are often smaller than their temperate conspecifics. Intraspecific studies integrating physiology and behaviour of different-sized individuals, may shed light on this paradox. 2. We...

Ancient horse genomes reveal the timing and extent of dispersals across the Bering Land Bridge

Alisa Vershinina, Peter Heintzman, Duane Froese, Grant Zazula, Molly Cassatt-Johnstone, Love Dalén, Clio Der Sarkissian, Shelby Dunn, Luca Ermini, Cristina Gamba, Pamela Groves, Joshua Kapp, Daniel Mann, Andaine Seguin-Orlando, John Southon, Mathias Stiller, Matthew Wooller, Gennady Baryshnikov, Dmitry Gimranov, Eric Scott, Elizabeth Hall, Susan Hewitson, Irina Kirillova, Pavel Kosintsev, Fedor Shidlovsky … & Beth Shapiro
The Bering Land Bridge (BLB) last connected Eurasia and North America during the Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations of a once wide-ranging group, the caballine horses (Equus spp.). Using a panel of 187 mitochondrial and...

Seasonal and annual dynamics of litterfall

Cunguo Wang, Xingbo Zheng, Anzhi Wang, Guanhua Dai, Baokun Zhu, Yueming Zhao, Shijie Dong, Weizhong Zu, Wei Wang, Yiguo Zheng & Mai-He Li
Long-term data of litterfall can indicate overall forest functions in forest ecosystems. We collected monthly (May – October) and annual (1981 – 2018) litterfall including leaves, twigs, bark, reproductive and miscellaneous fractions in a mixed mature Pinus koraiensis forest on Changbai Mountain in Northeast, China, across 30 years. Based on these long-term litterfall data, we analyzed the seasonal and annual variations in different litterfall fractions and their relationships with climatic factors. Climate data were obtained...

The dataset includes the mean length of copepods weighted by abundance found in 97,830 continuous plankton recorder (CPR) samples. Further, it contains satellite observations for sea surface temperature, chlorophyll-a, and dissolved oxygen (see paper for details). It was a massive collaborative effort to get this dataset assembled by the Global Alliance of CPR Surveys (GACS 2011,...

Data and script for: The patterns and modes of the evolution of disparity in Mesozoic Birds

Min Wang, Graeme Lloyd, Chi Zhang & Zhonghe Zhou
The origin of birds from non-avian theropod dinosaurs is one of the greatest transitions in evolution. Shortly after diverging from other theropods in the Late Jurassic, Mesozoic birds diversified into two major clades—the Enantiornithes and Ornithuromorpha—acquiring many features previously considered unique to the crown groups along the way. Here we present a comparative phylogenetic study of the patterns and modes of Mesozoic bird skeletal morphology and limb proportions. Our results show that the major Mesozoic...

The genome assembly and annotation of Magnolia biondii Pamp., a phylogenetically, economically, and medicinally important ornamental tree species

Shanshan Dong & Min Liu
Magnolia biondii Pamp. (Magnoliaceae, magnoliids) is a phylogenetically, economically, and medicinally important ornamental tree species widely grown and cultivated in the north-temperate regions of China. Contributing a genome sequence for M. biondii will help resolve phylogenetic uncertainty of magnoliids and further understand individual trait evolution in Magnolia. We assembled a chromosome-level reference genome of M. biondii using ~67, ~175, and ~154 Gb of raw DNA sequences generated by Pacific Biosciences Single-molecule Real-time sequencing, 10X genomics...

Slab metamorphism and interface earthquakes in Peru: implications for along-strike fluid content and seismotectonic variation

Ji Yingfeng
Evidenced by a typically shallow subducted thick mid-ocean ridge basalt (MORB) layer that dominates the subducting Nazca plate and a significant lack of arc magmatism, the Peruvian megathrust remain enigmatic in thermal regime and petrological metamorphism. Thermally controlled slab dehydration in the incoming plate may facilitate fluids release and migration which possibly causes fault instability and seismic and aseismic slips. We find that (1) the eclogitization of the MORB layer and the harzburgitization of the...

Raw presence-absence community composition of passerines, rodents, and ants at eastern slope of Mt. Segrila

Yuanbao Du
Along the eastern slope of Mt. Segrila, we performed field surveys for passerines, rodents, and ants, respectively. The compositional information of passerines was collected from 4-10 times’ field observations of 17 sampling transects (800 m-2,300 m) dating from June 2018/2019 to June 2020. Field survey on rodents included snap-trapping and field observations. Snap-trappings were conducted from nine sampling sites with two trapping surveys during early (March-July) and late (July-September) wet seasons in 2014. We also...

Genome of the butterfly hillstream loach provides insights into adaptations to torrential mountain stream life

Liandong Yang
Butterfly hillstream loach (Beaufortia kweichowensis), a benthic fish in torrential mountain streams, possesses a totally flat ventrum, flattened craniofacial and body skeletons, and enlarged paired fins covered by substantially small keratinous structures. However, little is known about the genetic basis of these specialized morphological adaptations. Here we present a 448.52 Mb genome assembly with contig N50 length of 5.53 Mb by integrating Illumina short-read sequencing, Nanopore long-read sequencing and HiC-based chromatin map. Demographic history reconstruction...

We examined the spatial pattern of the leaf δ13C...

Phylotranscriptomics reveal the complex evolutionary and biogeographic history of the genus Tsuga with an East Asian-North American disjunct distribution

Yuan-Yuan Feng, Ting-Ting Shen, Cheng-Cheng Shao, Hong Du, Jin-Hua Ran & Xiao-Quan Wang
The disjunct distribution between East Asia and North America is one of the best established biogeographic patterns. A robust phylogeny is fundamental for understanding the biogeographic histories of taxa with this distribution pattern. Tsuga (hemlock) is a genus of Pinaceae with a typical intercontinental disjunct distribution in East Asia and eastern and western North America, and its phylogeny has not been completely reconstructed in previous studies. In this study, we reconstructed a highly resolved phylogeny...

Data and code from: Accounting for species interactions is necessary for predicting how arctic arthropod communities respond to climate change

Nerea Abrego, Tomas Roslin, Tea Huotari, Yinqiu Ji, Niels Martin Schmid, Jiaxin Wang, Douglas W. Yu & Otso Ovaskainen
Species interactions are known to structure ecological communities. Still, the influence of climate change on biodiversity has primarily been evaluated by correlating individual species distributions with local climatic descriptors, then extrapolating into future climate scenarios. We ask whether predictions on arctic arthropod response to climate change can be improved by accounting for species interactions. For this, we use a 14-year-long, weekly time series from Greenland, resolved to the species level by mitogenome mapping. During the...

Multiple diversity facets of crucial microbial groups in biological soil crusts promote soil multifunctionality

Hua Li, Youxin Chen, Gongliang Yu, Federico Rossi, Da Huo, Roberto De Philippis, Xiaoli Cheng, Weibo Wang & Renhui Li
Aim: Microbial diversity is one of the most important factors for maintaining the performance of multiple functions in soils (multifunctionality). However, existing studies typically consider taxonomic richness or Shannon diversity of the entire community. We know little about the connection network of taxonomic and phylogenetic diversity facets and their collective impact on multifunctionality. In this study, the linkages of diversity effects within functional groups were disentangled in drylands. Location: The central Tibetan Plateau. Time period:...

Data from: A new species of the Cambrian bivalved euarthropod Pectocaris with axially differentiated enditic armatures

Changfei Jin, Huijuan Mai, Dayou Zhai, Hong Chen, Yu Liu, Xianguang Hou & Ruilin Wen
Although first described in 1999, the early Cambrian Pectocaris remains a poorly known euarthropod genus. As of now, two species, Pectocaris eurypetala and Pectocaris spatiosa, are known from the Chengjiang biota. Here, we report a third species, Pectocaris inopinata sp. nov., which bears a pair of stalked eyes attached to an anterior sclerite, a pair of short but stout antennae, 29–35 cephalothoracic segments each corresponding to a pair of biramous appendages, 11–12 limbless segments carrying...

Mitochondrial genes from eighteen angiosperms fill sampling gaps for phylogenomic inferences of the early diversification of flowering plants

Jia-Yu Xue & Yang Liu
The early diversification of angiosperms is a rapid yet complicated process and thus it renders the phylogenetic analyses of early-diverging angiosperms much difficulty. Plastid and nuclear phylogenomic studies have raised several controversial hypotheses regarding the angiosperm phylogeny, whereas mitochondrial genomes have been largely ignored. In this study, we newly sequenced mitochondrial genomes from 18 angiosperms to fill the sampling gaps in magnoliids, Austrobaileyales, Chloranthales, Ceratophyllales, and early-diverging lineages of eudicots and monocots. A data matrix...

Genetic architecture and adaptation of flowering time among environments

Thomas Mitchell-Olds, Baosheng Wang, Wenjie Yan & Emily Chan
1. The genetic basis of flowering time changes across environments, and pleiotropy may limit adaptive evolution of populations in response to local conditions. However, little is known about how genetic architecture changes among environments. 2. We used genome-wide association studies (GWAS) in Boechera stricta (Graham) Al-Shehbaz, a relative of Arabidopsis, to examine flowering variation among environments and associations with climate conditions in home environments. Also, we used molecular population genetics to search for evidence of...

Robust vestibular self-motion signals in macaque posterior cingulate region

Bingyu Liu, Qingyang Tian & Yong Gu
Self-motion signals, distributed ubiquitously across parietal-temporal lobes, propagate to limbic hippocampal system for vector-based navigation via hubs including posterior cingulate cortex (PCC) and retrosplenial cortex (RSC). Although numerous studies have indicated that posterior cingulate areas are involved in spatial tasks, it is unclear about how their neurons represent self-motion signals. By providing translation and rotation stimuli to macaques on a 6-degree-of-freedom motion platform, we discovered robust vestibular responses in PCC. A combined 3-dimensional spatiotemporal model...
