Ecological niche evolution can promote or hinder the differentiation of taxa and determine their distribution. Niche‐mediated evolution may differ among climatic regimes, and thus species that occur across a wide latitudinal range offer a chance to test these heterogeneous evolutionary processes. In this study, we examine (1) how many lineages have evolved across the continent‐wide range of the Eurasian nuthatch (Sitta europaea), (2) whether the lineages’ niches are significantly divergent or conserved, and (3) how...
Data from: Niches in the Anthropocene: passerine assemblages show niche expansion from natural to urban habitatsEmilio Pagani-Núñez, Dan Liang, Chao He, Xuemeng Zhou, Xu Luo, Yang Liu & Eben Goodale
Human‐mediated habitat transformation is increasingly evident around the world. Yet, how this transformation influences species’ niche width and overlap remains unclear. On the one hand, human‐mediated habitat transformation promotes increased species similarity through trait‐based filtering, and an increased prevalence of generalist species with broad niches, resulting in functional homogenization. On the other hand, species that colonize transformed habitats could use empty niches, resulting in decreased species similarity and an expansion of assemblage‐level niche space. Here...
Data from: The inverted U-shaped effect of urban hotspots spatial compactness on urban economic growthWeipan Xu, Haohui Chen, Enrique Frias-Martinez, Manuel Cebrian & Xun Li
The compact city, as a sustainable concept, is intended to augment the efficiency of urban function. However, previous studies have concentrated more on morphology than on structure. The present study focuses on urban structural elements, i.e., urban hotspots consisting of high-density and high-intensity socioeconomic zones, and explores the economic performance associated with their spatial structure. We use nighttime luminosity (NTL) data and the Loubar method to identify and extract the hotspot and ultimately draw two...
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...
Data from: Genomic changes in the biological control agent Cryptolaemus montrouzieri associated with introductionHao-Sen Li, Gerald Heckel, Yu-Hao Huang, Wei-Jian Fan, Adam Ślipiński & Hong Pang
Biological control is the main purpose of intentionally introducing non-native invertebrate species. The evolutionary changes that occur in the populations of the introduced biological control agents may determine the agent's efficiency and the environmental safety. Here, to explore the pattern and extent of potential genomic changes in the worldwide introduced predatory ladybird beetle Cryptolaemus montrouzieri, we used a reduced-representation sequencing method to analyze the genome-wide differentiation of the samples from two native and five introduced...
Plants are often repeatedly exposed to stresses during their lives and have a mechanism called stress imprinting that provides ‘memories’ of stresses they experience and increases their ability to cope with later stresses. To test hypotheses that primed bryophytes can preserve their stress imprinting after 6 days of recovery and induce higher levels of osmolytes and ROS-scavenging activities upon later stress exposure, and there exist population-level differentiation in their desiccation defenses, we transplanted samples of...
Data from: Extra-pair mating opportunities mediate parenting and mating effort trade-offs in a songbirdLei Lv, Zhengwang Zhang, Frank Groenewoud, Sjouke Anne Kingma, Jianqiang Li, Marco Van Der Velde & Jan Komdeur
In socially monogamous species with bi-parental care, males may face a trade-off between providing parental care and pursuing extra-pair matings. The “parenting-mating trade-off” hypothesis predicts that high-quality males – who have greater potential to gain extra-pair matings, e.g. larger males usually win the competition for extra-pair mating – should reduce parental care and spend more time looking for extra-pair matings. However, the trade-off between parenting and mating efforts may be complicated by variation in the...
Data from: SRUD: a simple non-destructive method for accurate quantification of plant diversity dynamicsPengfei Zhang, George A. Kowalchuk, Merel B. Soons, Mariet M. Hefting, Chengjin Chu, Jennifer Firn, Cynthia S. Brown, Xianhui Zhou, Xiaolong Zhou, Zhi Guo, Zhigang Zhao, Guozhen Du & Yann Hautier
1. Predicting changes in plant diversity in response to human activities represents one of the major challenges facing ecologists and land managers striving for sustainable ecosystem management. Classical field studies have emphasized the importance of community primary productivity in regulating changes in plant species richness. However, experimental studies have yielded inconsistent empirical evidence, suggesting that primary productivity is not the sole determinant of plant diversity. Recent work has shown that more accurate predictions of changes...
Data from: Context-dependent strategies of food allocation among offspring in a facultative cooperative breederJianqiang Li, Yong Wang, Lei Lv, Pengcheng Wang, Ben J. Hatchwell & Zhengwang Zhang
Natural selection should favor adoption of parental strategies that maximize fitness when allocating investment among offspring. In birds, begging displays often convey information of nestling need and quality, allowing parents to make adaptive food allocation decisions. We investigated how adults utilized cues likely to represent nestling competitive ability (begging position) and need (begging intensity), and a cue independent of nestling control (nestling sex) to distribute food among nestlings in a facultative cooperative breeder, the black-throated...
Data from: Genetic diversity, demographic history and neo-sex chromosomes in the Critically Endangered Raso larkElisa G. Dierickx, Simon Yung Wa Sin, Pieter Van Veelen, M. De L. Brooke, Yang Liu, Scott V. Edwards & Simon H. Martin
Small effective population sizes could expose island species to inbreeding and loss of genetic variation. Here, we investigate factors shaping genetic diversity in the Raso lark, which has been restricted to a single islet for approximately 500 years, with a population size of a few hundred. We assembled a reference genome for the related Eurasian skylark and then assessed diversity and demographic history using RAD-seq data (75 samples from Raso larks and two related mainland...
Growth, biomass allocation and tissue nutrient concentrations of subtropical and tropical tree seedlings in response to experimental manipulation of soil phosphorus poolsD Burslem, X. Liu, D. Johnson, A. Taylor, J. Taylor, T. Helgason, Y. Chen & M. Liang
This dataset reports metrics of plant growth, including height, total biomass and the biomass of component plant parts, and percentage root colonisation by mycorrhizas, for tree seedlings of eight tropical and seven subtropical growing in pots of soil that had been amended by addition of various sources of phosphorus (inorganic phosphate, adenosine monophosphate, phytic, or a mixture of all three) plus an unfertilized control treatment with no P additions. The aim of the experiment was...
Data from: Games academics play and their consequences: how authorship, h-index, and journal impact factors are shaping the future of academiaJan Gogarten, Colin Chapman, Julio Bicca-Marques, Sébastien Calvignac-Spencer, Pengfei Fan, Peter Fashing, Songtao Guo, Claire Hemingway, Fabian Leendertz, Baoguo Li, Ikki Matsuda, Rong Hou, Juan Carlos Serio-Silva & Nils Chr. Stenseth
Research is a highly competitive profession where evaluation plays a central role; journals are ranked and individuals are evaluated based on their publication number, the number of times they are cited, and their h-index. Yet, such evaluations are often done in inappropriate ways that are damaging to individual careers, particularly for young scholars, and to the profession. Furthermore, as with all indices, people can play games to better their scores. This has resulted in the...
Lightning strike is an important ignition source of forest fires. Artificial lightning discharge is a method for studying lightning fires. However, there is not enough data on the ignition of combustible materials caused by artificial lightning discharge. Previous studies on lightning ignition have focused on the heating and ignition effects of long continuing current (LCC), but the function of the impulse current that occurs before the LCC has not been taken into account. In this...
