Undersampling correction methods to control γ-dependence for comparing β-diversity between regions

Ke Cao, Jens-Christian Svenning, Chuan Yan, Jintun Zhang, Xiangcheng Mi & Keping Ma
Measures of β-diversity are known to be highly constrained by the variation in γ-diversity across regions (i.e., γ-dependence), making it challenging to infer underlying ecological processes. Undersampling correction methods have attempted to estimate the actual β-diversity in order to minimize the effects of γ-dependence arising from the problem of incomplete sampling. However, no study has systematically tested their effectiveness in removing γ-dependence, and examined how well undersampling-corrected β-metrics reflect true β-diversity patterns that respond to...

Data from: Compensatory adaptation and diversification subsequent to evolutionary rescue in a model adaptive radiation

Dong-Hao Zhou & Quan-Guo Zhang
Biological populations may survive lethal environmental stress through evolutionary rescue. The rescued populations typically suffer a reduction in growth performance and harbour very low genetic diversity compared with their parental populations. The present study addresses how population size and within-population diversity may recover through compensatory evolution, using the experimental adaptive radiation of bacterium Pseudomonas fluorescens. We exposed bacterial populations to an antibiotic treatment; and then imposed a one-individual-size population bottleneck on those surviving the antibiotic...

In addition, the sample information: geographical locations of collections and...

Do annual and perennial populations of an insect-pollinated plant species differ in mating system?

Wei-Ning Bai, Yue Ma, Spencer Barrett, Fang-Yuan Wang & Jun-Chen Deng
Background and Aims Theory predicts that outcrossing should be more prevalent among perennials than annuals, a pattern confirmed by comparative evidence from diverse angiosperm families. However, intraspecific comparisons between annual and perennial populations are few because such variation is uncommon among flowering plants. Here, we test the hypothesis that perennial populations outcross more than annual populations by investigating Incarvillea sinensis, a wide-ranging insect-pollinated herb native to China. The occurrence of both allopatric and sympatric populations...

Energetic constraints imposed on trophic interaction strengths enhance resilience in empirical and model food webs

Xiaoxiao Li, Wei Yang, Ursula Gaedke & Peter De Ruiter
1. Food web stability and resilience are at the heart of understanding the structure and functioning of ecosystems. Previous studies show that models of empirical food webs are substantially more stable than random ones, due to a few strong interactions embedded in a majority of weak interactions. Analyses of trophic interaction loops show that in empirical food webs the patterns in the interaction strengths prevent the occurrence of destabilizing heavy loops and thereby enhances resilience....

WiBB: An integrated method for quantifying the relative importance of predictive variables

Qin Li & Xiaojun Kou
This dataset contains simulated datasets, empirical data, and R scripts described in the paper: “Li, Q. and Kou, X. (2021) WiBB: An integrated method for quantifying the relative importance of predictive variables. Ecography (DOI: 10.1111/ecog.05651)”. A fundamental goal of scientific research is to identify the underlying variables that govern crucial processes of a system. Here we proposed a new index, WiBB, which integrates the merits of several existing methods: a model-weighting method from information theory...

Genome, annotations and SNPs for the green peafowl and associated scripts

Feng Dong, Hao-Chih Kuo, Guo-Ling Chen, Fei Wu, Peng-Fei Shan, Jie Wang, De Chen, Chih-Ming Hung, Yang Liu & Xiao-Jun Yang
Both anthropogenic impacts and historical climate change could contribute to population decline and species extinction, but their relative importance has yet to be determined. Emerging approaches based on genomic, climatic and anthropogenic data provide a promising analytical framework to address this question. This study applied such an integrative approach to examine potential drivers for endangerment of the green peafowl (Pavo muticus). Several demographic reconstructions based on population genomes congruently retrieved a drastic population declination since...

Assessing mammal species richness and occupancy in a Northeast Asian temperate forest shared by cattle

Jiawei Feng, Yifei Sun, Hailong Li, Yuqi Xiao, Dandan Zhang, James Smith, Jianping Ge & Tianming Wang
Aim: Asian forests are becoming increasingly degraded and fragmented by the extensive intensification of anthropogenic activities; these activities threaten wildlife and ecosystem sustainability. Facing a defaunation crisis, managers need more information on species assemblages to guide conservation efforts. We tested the relative influence of natural and anthropogenic factors on mammalian species richness and occupancy in temperate forests in Northeast Asia. Location: Northeast China. Methods: Camera-trapping data and multi-species occupancy models were used to estimate the...

Data from: Reciprocal facilitation between annual plants and burrowing crabs: implications for the restoration of degraded salt marshes

Dongdong Qiu, Baoshan Cui, Xu Ma, Jiaguo Yan, Yanzi Cai, Tian Xie, Fang Gao, Fangfang Wang, Haochen Sui, Junhong Bai, Johan Van De Koppel & Han Olff
​​​​​​Increasing evidence shows that facilitative interactions between species play an essential role in coastal wetland ecosystems. However, there is a lack of understanding of how such interactions can be used for restoration purposes in salt marsh ecosystems. We, therefore, studied the mechanisms of reciprocal facilitative interactions between native annual plants, Suaeda salsa, and burrowing crabs, Helice tientsinensis, in a middle-elevation salt marsh (with generally high plant density and moderate tides) in the Yellow River Delta...

An invasive species erodes the performance of coastal wetland protected areas

Junlin Ren, Jianshe Chen, Changlin Xu, Johan Van De Koppel, Mads Thomsen, Shi-Yun Qiu, Fangyan Cheng, Wanjuan Song, Quan-Xing Liu, Chi Xu, Junhong Bai, Yihui Zhang, Baoshan Cui, Mark Bertness, Brian Silliman, Bo Li & Qiang He
The world has increasingly relied upon protected areas (PAs) to rescue highly valued ecosystems from human activities, but whether PAs will fare well with bioinvasions remains unknown. By analyzing three decades of seven largest coastal PAs in China, including multiple World Natural Heritage and/or Wetlands of International Importance sites, we show that although PAs are achieving success in rescuing iconic wetlands and critical shorebird habitats from once widespread reclamation, this success is counteracted by escalating...

Insights into the aggregation mechanism of RRM domains in TDP-43: A theoretical exploration

Chaoqun Li, Wei Liu, Jiankai Shan, Yang Wang & Guangju Chen
The transactive response DNA-binding protein 43 (TDP-43) is associated with several diseases such as Amyotrophic lateral sclerosis (ALS) and Frontotemporal lobar degeneration (FTLD) due to pathogenic aggregations. In this work, we examined the dimer, tetramer and hexamer models built from the RRM domains of TDP-43 using molecular dynamics simulations in combination with the protein-protein docking. Our results showed that the formations of the dimer models are mainly achieved by the interactions of the RRM1 domains....

Host personality predicts cuckoo egg rejection in Daurian redstarts Phoenicurus auroreus

Jinggang Zhang, Peter Santema, Jianqiang Li, Lixing Yang, Wenhong Deng & Bart Kempenaers
In species that are subject to brood parasitism, there is typically variation in individuals’ responses to parasitic eggs, with some rejecting the eggs while others do not. Whilst some factors, such as host age (breeding experience), the degree of egg matching and the level of perceived risk of brood parasitism have been shown to influence host decisions, a lot of the variation remains unexplained. The host personality hypothesis suggests that personality traits of the host...

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...

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...

How hydrological connectivity regulates the plant recovery process in salt marshes

Qing Wang, Tian Xie, Meng Luo, Junhong Bai, Cong Chen, Zhonghua Ning & Baoshan Cui
1. Designing effective restoration strategies is a priority in recovering salt marsh plants. As a main driver underpinning the success of plant recovery process, hydrological connectivity can regulate life history process-based restoration strategies, but the relations are not clear. 2. Plant recovering needs to go through a whole life history process, from seed to adult. Common restoration strategies are seed addition (SA) or seedling transplantation (ST), which start from seed germination and seedling growth stage....

Plot-level wood-leaf separation for terrestrial laser scanning point clouds

Peng Wan, Wuming Zhang & Shuangna Jin
With the increasing use of terrestrial laser scanning (TLS) technology in the field of forest ecology, wood-leaf separation for TLS point clouds of forest plots has attracted a large number of studies. This dataset was open to the public for the developing, testing and comparision of the wood-leaf separation methods for TLS data. The dataset was collected from three forest plots of different stem density, topography and tree species, i.e., a white birch (Betula papyrifera)...

Densities of mollusc species at different sites along the Chinese coast

He-Bo Peng, Ying-Chi Chan, Tanya Compton, Xue-Fei Cheng, David Melville, Shou-Dong Zhang, Zhengwang Zhang, Guangchun Lei, Zhijun Ma & Theunis Piersma
Aim: Molluscs are important grazers, filter and deposit feeders, scavengers and predators, which in turn are food for shorebirds, fish and people. Some species, targeted as human food, have been cultured along the Chinese coast for hundreds of years. To examine whether aquacultural practices have meanwhile affected biodiversity gradients, we measured mollusc community structure along the coast of China in habitats which are intensively used by humans. Location: Chinese coast Methods: We sampled 21 intertidal...

Data for: A novel function of banded stripes to prevent cannibalism in snake-eating snakes

Nicholas Wu, Juan Lei & Zhengwang Zhang
Colour pattern are widespread in the animal kingdom and have various functions that play key roles in many ecological interactions. We present a novel function for the evolution of banded stripes in preventing cannibalism in snakes that feed on other snakes—ophiophagy. We first examined the phylogenetic relationship between ophiophagy and banded stripes by categorising pattern types and known diet of 3,568 snake species. We then conducted a series of behavioural predation experiments with California kingsnake...

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...

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...
