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...

Three‐dimensional soil heterogeneity modulates responses of grassland mesocosms to an experimentally imposed drought extreme

Yongjie Liu, Michiel F. Bortier, Ivan Nijs, Yongshuo Fu, Zhenqing Li, Fujiang Hou & Hans J. De Boeck
Heterogeneity is an intrinsic characteristic of soils, which regulates plant diversity and ecosystem functioning. However, whether soil heterogeneity also modulates responses of plant communities to climate change, including climate extremes, remains largely an open question. Here, we explore responses of plant communities to drought extremes across four levels of spatial soil heterogeneity, with cell sizes varying from very small to very large, i.e. 0, 12, 24 and 48 cm. These were created in mesocosms by...

Cailing Li, Liyun Jiang, Xiaolu Zhang, Jing Chen & Gexia Qiao
In this study, we sequenced the complete mitochondrial genome of Eutrichosiphum pasaniae through Illumina platform. The circular mitogenome is 16,500 bp in length and composed of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), a large control region and a special repeat region. The nucleotide composition of whole mitogenome is strongly AT-biased (85.5%). All PCGs start with ATN and end with TAA except for cox1 which terminates with an...

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...

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...

Hedyotis pubirachis (Rubiaceae), a new species from Guangdong, China

Yi Da Xu & Rui Jiang Wang
A new species of Hedyotis pubirachis is described from Guangdong province, China. It resembles H. caudatifolia in subshrub habit, lanceolate leaf blade and terminal inflorescence, but differs from the latter by its thyrsoid inflorescence with monochasial subaxes, broadly triangular calyx lobes and pubescent inflorescence rachises and capsules. Phylogenetically, Hedyotis pubirachis is close to H. effusa but they can be distinguished in the indument of the inflorescence and capsules and the length of pedicels. Pollen size...

Nonlinear responses of ecosystem carbon fluxes to nitrogen deposition in an old-growth boreal forest

Aijun Xing, Enzai Du, Haihua Shen, Longchao Xu, Wim De Vries, Mengying Zhao, Xiuyuan Liu & Jingyun Fang
Nitrogen (N) deposition is known to increase carbon (C) sequestration in N-limited boreal forests. However, the long-term effects of N deposition on ecosystem carbon fluxes have been rarely investigated in old-growth boreal forests. Here we show that decade-long experimental N additions significantly stimulated net primary production (NPP) but the effect decreased with increasing N loads. The effect on soil heterotrophic respiration (Rh) shifted from a stimulation at low-level N additions to an inhibition at higher...

Nitrogen addition, rather than altered precipitation, stimulates nitrous oxide emissions in an alpine steppe

Yang Yang, Yuanming Xiao, Changbin Li, Bo Wang, Yongheng Gao & Guoying Zhou
Anthropogenic-driven global change, including changes in atmospheric nitrogen (N) deposition and precipitation patterns, is dramatically altering N cycling in soil. How long-term N deposition, precipitation changes, and their interaction influence nitrous oxide (N2O) emissions remains unknown, especially in the alpine steppes of the Qinghai-Tibetan Plateau (QTP). To fill this knowledge gap, a platform of N addition (10 g m−2 yr−1) and altered precipitation (± 50% precipitation) experiments was established in an alpine steppe of the...

Deepened snow cover mitigates soil carbon loss from intensive land use in a semi-arid temperate grassland

Ping Li, Emma Sayer, Zhou Jia, Yuntao Wu, Meifeng Deng, Xin Wang, Chao Liu, Bin Wang, Yang Wang, Yongfei Bai & Lingli Liu
Carbon (C) loss due to soil erosion is a major issue in semi-arid grasslands. The extent of soil erosion is determined by soil properties and vegetation structure, especially during the non-growing season. In many Inner Mongolian grasslands, intensive land use, such as overgrazing and mowing, has severely reduced plant cover and damaged soil structure, which has exacerbated soil C loss by erosion. At the same time, increasing winter snowfall due to climate change is stimulating...

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...

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:...

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...

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...

Connectional asymmetry of the inferior parietal lobule shapes hemispheric specialization in humans, chimpanzees, and rhesus macaques

Luqi Cheng, Yuanchao Zhang, Gang Li, Jiaojian Wang, Chet Sherwood, Gaolang Gong, Linzhong Fan & Tianzi Jiang
The inferior parietal lobule (IPL) is one of the most expanded cortical regions in humans relative to other primates. It is also among the most structurally and functionally asymmetric regions in the human cerebral cortex. Whether the structural and connectional asymmetries of IPL subdivisions differ across primate species and how this relates to functional asymmetries remain unclear. We identified IPL subregions that exhibited positive allometric in both hemispheres, scaling across rhesus macaque monkeys, chimpanzees, and...

Improving intra- and inter-annual GPP predictions by using individual-tree inventories and leaf growth dynamics

Jing Fang, James Lutz, Herman Shugart, Xiaodong Yan, Wenqiang Xie & Feng Liu
Carbon sequestration is a key ecosystem service provided by forests. Inventory data based on individual trees are considered to be the most accurate method for estimating forest productivity. However, estimations of forest photosynthesis itself from inventory data remains understudied, particularly when considering the growth and development of individual trees under the background of global change. Here, we used the leaf growth process with phenology and non-structural carbohydrates (NSC) storage to revise an individual-tree based carbon...

Yuzheng Ke, Rui Wu, Darla Zelenitsky, Don Brinkman, Jinfeng Hu, Shukang Zhang, Haishui Jiang & Fenglu Han
Turtle eggs containing embryos are exceedingly rare in the fossil record. Here, we provide the first description and taxonomic identification, to our knowledge, of a fossilized embryonic turtle preserved in an egg, a fossil recovered from the Upper Cretaceous Xiaguan Formation of Henan Province, China. Through Computed Tomography and Three-Dimensional reconstruction, many bones can be clearly displayed, including the maxillae, mandibles, ribs, plastral plates, scapula, forelimbs, and hind limbs. The specimen is attributed to the...

Phylogenomic and macroevolutionary evidence for an explosive radiation of a plant genus in the Miocene

Hanghui Kong, Fabien L. Condamine, Lihua Yang, AJ Harris, Chao Feng, Fang Wen & Ming Kang
Mountain systems harbor a substantial fraction of global biodiversity and, thus, provide excellent opportunities to study rapid diversification and to understand the historical processes underlying the assembly of biodiversity hotspots. The rich biodiversity in mountains is widely regarded as having arisen under the influence of geological and climatic processes as well as the complex interactions among them. However, the relative contribution of geology and climate in driving species radiation is seldom explored. Here, we studied...

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 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...

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...

Community species diversity mediates the trade-off between aboveground and belowground biomass for grasses and forbs in degraded alpine meadow, Tibetan Plateau

Tiancai Zhou
Although many empirical experiments have shown that increasing degradation results in lower aboveground biomass (AGB), our knowledge of the magnitude of belowground biomass (BGB) for individual plants is a prerequisite for accurately revealing the biomass trade-off in degraded grasslands. Here, by linking the AGB and BGB of individual plants, species in the community, and soil properties, we explored the biomass partitioning patterns in different plant functional groups (grasses of Stipa capillacea and forbs of Anaphalis...

We investigate thermal acclimation of three species of Takydromus lizards distributed along a broad latitudinal gradient in China. The dataset are including metabolic rates, organ size, mitochondrial respiration, Cox activities, proteomic and metabolomic regulations of three Takydromus lizards after warm and cold acclimation in the laboratory. See details in related paper.

Maternal effects of climate warming and nitrogen deposition vary with home and introduced ranges

Wei-Ming He, Xiao-Hui Zhou, Jing-Ji Li, Yuan-Yuan Gao & Pei-Hao Peng
Maternal effects allow offspring to cope with changing environments. While the immediate effects of climate warming and nitrogen (N) deposition are well documented, their maternal effects have been little studied. We conducted a 6-year maternal experiment with Solidago canadensis, native to North America and invasive in China, and two offspring experiments to address how maternal warming, maternal N-addition and population source interacted to influence offspring performance. Maternal effects of warming and N-addition on seed traits,...
