Aim To investigate the role of traits in beetle community assembly and test for consistency in these effects among several bioclimatic regions. We asked (1) whether traits predicted species’ responses to environmental gradients (i.e., their niches), (2) whether these same traits could predict co-occurrence patterns, and (3) how consistent were niches and the role of traits among study regions. Location Boreal forests in Norway and Finland, temperate forests in Germany. Methods We complied capture records...

Competition and geography underlie speciation and morphological evolution in Indo-Australasian monitor lizards

Carlos J. Pavón-Vázquez, Ian G. Brennan, Alexander Skeels & J. Scott Keogh
How biotic and abiotic factors act together to shape biological diversity is a major question in evolutionary biology. The recent availability of large datasets and development of new methodological approaches provide new tools to evaluate the predicted effects of ecological interactions and geography on lineage diversification and phenotypic evolution. Here, we use a near complete phylogenomic-scale phylogeny and a comprehensive morphological dataset comprising more than a thousand specimens to assess the role of biotic and...

On the occasion of the release of v4.4 of the DataCite Metadata Schema its Metadata Working Group has updated the mapping to Dublin Core. This replaces the mapping in the Appendix of the DataCite-MetadataKernel v2.1. The mapping can be used to convert records described following version 4.4 of the DataCite Metadata Schema into records that comply with the Dublin Core Metadata Initiative Schema.

Diffusion-mediated HEI10 coarsening can explain meiotic crossover positioning in Arabidopsis

Christopher Morgan
In most organisms, the number and distribution of crossovers that occur during meiosis are tightly controlled. All chromosomes must receive at least one “obligatory crossover” and crossovers are prevented from occurring near one another by “crossover interference”. However, the mechanistic basis of this phenomenon of crossover interference has remained mostly mysterious. Using quantitative super-resolution cytogenetics and mathematical modelling, we investigated crossover positioning in the Arabidopsis thaliana wild-type, an over-expressor of the conserved E3 ligase HEI10,...

The role of surface adhesion on the macroscopic wrinkling of biofilms

Steffen Geisel, Eleonora Secchi & Jan Vermant
Biofilms, bacterial communities of cells encased by a self-produced matrix, exhibit a variety of three-dimensional structures. Specifically, channel networks formed within the bulk of the biofilm have been identified to play an important role in the colonies viability by promoting the transport of nutrients and chemicals. Here, we study channel formation and focus on the role of the adhesion of the biofilm matrix to the substrate in Pseudomonas aeruginosa biofilms grown under constant flow in...

Data from: Horizontal Transmission of the Heritable Protective Endosymbiont Hamiltonella defensa Depends on Titre and Haplotype

Heidi Kaech & Christoph Vorburger
Secondary endosymbionts of aphids have an important ecological and evolutionary impact on their host, as they provide resistance to natural enemies but also reduce the host’s lifespan and reproduction. While secondary symbionts of aphids are faithfully transmitted from mother to offspring, they also have some capacity to be transmitted horizontally between aphids. Here we explore whether 11 isolates from 3 haplotypes of the secondary endosymbiont Hamiltonella defensa differ in their capacity for horizontal transmission. These...

Species ecology explains the various spatial components of genetic diversity in tropical reef fishes

Giulia Francesca Azzurra Donati, Niklaus Zemp, Stéphanie Manel, Maude Poirier, Thomas Claverie, Franck Ferraton, Théo Gaboriau, Rodney Govinden, Oskar Hagen, Shameel Ibrahim, David Mouillot, Julien Leblond, Pagu Julius, Laure Velez, Irthisham Zareer, Adam Ziyad, Fabien Leprieur, Camille Albouy & Loïc Pellissier
Generating genomic data for 19 tropical reef fish species of the Western Indian Ocean, we investigate how species ecology influences genetic diver- sity patterns from local to regional scales. We distinguish between the α, β and γ components of genetic diversity, which we subsequently link to six ecological traits. We find that the α and γ components of genetic diversity are strongly correlated so that species with a high total regional genetic diversity display systematically...

Microsatellite data of Vincetoxicum hirundinaria offspring and their inferred mother plants from 13 populations in the South-Western Finnish Archipelago

Anne Muola, J. F. Scheepens, Liisa Laukkanen, Aino Kalske, Pia Mutikainen & Roosa Leimu
Fragmented landscapes may have implications for the genetic structure of populations and for the microevolution of plant species. In particular, landscape fragmentation and/or population isolation might affect the evolution of plant mating systems. Here, we study the consequences of landscape fragmentation on the genetic structure of populations of a perennial herb, Vincetoxicum hirundinaria with a mixed mating system. Our study area, the south-western Finnish archipelago, was formed after the glacial ice sheet started to retreat...

Dataset: Drivers of local extinction risk in alpine plants under warming climate

Hanna Nomoto & Jake Alexander
The scarcity of local plant extinctions following recent climate change has been explained by demographic inertia and lags in the displacement of resident species by novel species, generating an “extinction debt”. We established a transplant experiment to disentangle the contribution of these processes to local extinction risk of four alpine plants in the Swiss Alps. Projected population growth (λ) derived from integral projection models was reduced by 0.07/°C of warming on average, while novel species...

Raw data: multispecies amplicon sequencing (Loera, Studer, and Kölliker, 2021, Molecular Ecology Resources)

Miguel Loera-Sánchez, Bruno Studer & Roland Kölliker
Grasslands cover close to two fifths of Earth's land. They provide many ecosystem services related to the maintenance of soil integrity, and the regulation of water, carbon and nitrogen flows. Grasslands constitute the basis for sustainable roughage production for ruminant feeding. In Switzerland, grasslands cover more than 70% of the total agricultural land, which highlights their importance in the domestic food production chains. Plant genetic diversity (PGD), a component of biodiversity, influences ecosystem functioning in...

Online Appendix and Cetacean Datasets for: The Occurrence Birth-Death Process for combined-evidence analysis in macroevolution and epidemiology

Jérémy Andréoletti, Antoine Zwaans, Rachel Warnock, Gabriel Aguirre-Fernández, Joëlle Barido-Sottani, Ankit Gupta, Tanja Stadler & Marc Manceau
Phylodynamic models generally aim at jointly inferring phylogenetic relationships, model parameters, and more recently, the number of lineages through time, based on molecular sequence data. In the fields of epidemiology and macroevolution these models can be used to estimate, respectively, the past number of infected individuals (prevalence) or the past number of species (paleodiversity) through time. Recent years have seen the development of “total-evidence” analyses, which combine molecular and morphological data from extant and past...

Quantitative assessment of agricultural sustainability reveals divergent priorities among nations

Guolin Yao, Xin Zhang, Srishti Vishwakarma, Carole Dalin, Adam Komarek, David Kanter, Kyle Davis, Kimberly Pfeifer, Jing Zhao, Tan Zou, Paolo D'Odorico, Christian Folberth, Fernando Galeana Rodriguez, Jessica Fanzo, Lorenzo Rosa, William Dennison, Mark Musumba, Amy Heyman & Eric Davidson
Agriculture is fundamental to all three pillars of sustainability, environment, society, and economy. However, the definition of sustainable agriculture and capacities to measure it remain elusive. Independent and transparent measurements of national sustainability are needed to gauge progress, encourage accountability, and inform policy. Here, we developed a Sustainable Agriculture Matrix (SAM) to quantify national performance indicators in agriculture and to investigate the tradeoffs and synergies based on historical data for most countries of the world....

Engineering ‘smart’ viral RNA structures for stable and targeted siRNA delivery

Alyssa Hill
Innovative delivery strategies are needed in order to realize the potential of small interfering RNA (siRNA) in medicine. SiRNAs are short, double-stranded RNA molecules that silence genes by co-opting an endogenous RNA interference (RNAi) pathway. Because they act on messenger RNA (mRNA) sequences via RNAi, siRNAs hold promise as potentially curative therapies for genetic defects, autoimmune disorders, cancers, and other diseases that cannot be treated with traditional, protein-binding small molecule drugs and biologics. However, key...

No restrictions for reuse.

Data from: A sensory bias overrides learned preferences of bumblebees for honest signals in Mimulus guttatus

Ariela Haber, James Sims, Mark Mescher, Consuelo De Moraes & David Carr
Insect pollinators readily learn olfactory cues, and this is expected to select for “honest signals” that provide reliable information about floral rewards. However, plants might alternatively produce signals that exploit pollinators’ sensory biases, thereby relaxing selection for signal honesty. We examined the innate and learned preferences of Bombus impatiens for Mimulus guttatus floral scent phenotypes corresponding to different levels of pollen rewards in the presence and absence of the innately attractive floral volatile compound β-trans-bergamotene....

How biases in sperm storage relate to sperm use during oviposition in female yellow dung flies

Marco Demont, Paul Ward, Wolf Blanckenhorn, Stefan Lüpold, Oliver Martin & Luc Bussière
Precise mechanisms underlying sperm storage and utilization are largely unknown, and data directly linking stored sperm to paternity remain scarce. We used competitive microsatellite PCR to study the effects of female morphology, copula duration and oviposition on the proportion of stored sperm provided by the second of two copulating males (S2) in Scathophaga stercoraria (Diptera: Scathophagidae), the classic model for sperm competition studies. We genotyped all offspring from potentially mixed-paternity clutches to establish the relationship...
