Data from: Population genetic dynamics of an invasion reconstructed from the sediment egg bank

Markus Möst, Sarah Oexle, Silvia Markova, Dalia Aidukaite, Livia Baumgartner, Hans-Bernd Stich, Martin Wessels, Dominik Martin-Creuzburg & Piet Spaak
Biological invasions are a global issue with far-reaching consequences for single species, communities and whole ecosystems. Our understanding of modes and mechanisms of biological invasions requires knowledge of the genetic processes associated with successful invasions. In many instances, this information is particularly difficult to obtain as the initial phases of the invasion process often pass unnoticed and we rely on inferences from contemporary population genetic data. Here, we combined historic information with the genetic analysis...

Data from: Why there are no essential genes on plasmids

Samuel J. Tazzyman & Sebastian Bonhoeffer
Mobile genetic elements such as plasmids are important for the evolution of prokaryotes. It has been suggested that there are differences between functions coded for by mobile genes and those in the “core” genome and that these differences can be seen between plasmids and chromosomes. In particular, it has been suggested that essential genes, such as those involved in the formation of structural proteins or in basic metabolic functions, are rarely located on plasmids. We...

Data from: QTL mapping of temperature sensitivity reveals candidate genes for thermal adaptation and growth morphology in the plant pathogenic fungus Zymoseptoria tritici

Mark H. Lendenmann, Daniel Croll, Javier Palma-Guerrero, Ethan L. Stewart & Bruce A. McDonald
Different thermal environments impose strong, differential selection on populations, leading to local adaptation, but the genetic basis of thermal adaptation is poorly understood. We used quantitative trait locus (QTL) mapping in the fungal wheat pathogen Zymoseptoria tritici to study the genetic architecture of thermal adaptation and identify candidate genes. Four wild-type strains originating from the same thermal environment were crossed to generate two mapping populations with 263 (cross 1) and 261 (cross 2) progeny. Restriction...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Efficient detection of novel nuclear markers for Brassicaceae by transcriptome sequencing

Reinhold Stockenhuber, Stefan Zoller, Rie Shimizu-Inatsugi, Felix Gugerli, Kentaro K. Shimizu, Alex Widmer & Martin C. Fischer
The lack of DNA sequence information for most non-model organisms impairs the design of primers that are universally applicable for the study of molecular polymorphisms in nuclear markers. Next-generation sequencing (NGS) techniques nowadays provide a powerful approach to overcome this limitation. We present a flexible and inexpensive method to identify large numbers of nuclear primer pairs that amplify in most Brassicaceae species. We first obtained and mapped NGS transcriptome sequencing reads from two of the...

Data from: Spatiotemporal dynamics of Puumala hantavirus associated with its rodent host, Myodes glareolus

Vanessa Weber De Melo, Hanan Sheik Ali, Jona Freise, Denise Kühnert, Sandra Essbauer, Marc Mertens, Konrad M. Wanka, Stephan Drewes, Rainer G. Ulrich, Gerald Heckel & Hanan Sheikh Ali
Many viruses significantly impact human and animal health. Understanding the population dynamics of these viruses and their hosts can provide important insights for epidemiology and virus evolution. Puumala virus (PUUV) is a European hantavirus that may cause regional outbreaks of hemorrhagic fever with renal syndrome in humans. Here, we analyzed the spatiotemporal dynamics of PUUV circulating in local populations of its rodent reservoir host, the bank vole (Myodes glareolus) during eight years. Phylogenetic and population...

Data from: Current methods for automated filtering of multiple sequence alignments frequently worsen single-gene phylogenetic inference

Ge Tan, Matthieu Muffato, Christian Ledergerber, Javier Herrero, Nick Goldman, Manuel Gil & Christophe Dessimoz
Phylogenetic inference is generally performed on the basis of multiple sequence alignments (MSA). Because errors in an alignment can lead to errors in tree estimation, there is a strong interest in identifying and removing unreliable parts of the alignment. In recent years several automated filtering approaches have been proposed, but despite their popularity, a systematic and comprehensive comparison of different alignment filtering methods on real data has been lacking. Here, we extend and apply recently...

Data from: Quantifying age-dependent extinction from species phylogenies

Helen K. Alexander, Amaury Lambert & Tanja Stadler
Several ecological factors that could play into species extinction are expected to correlate with species age, i.e., time elapsed since the species arose by speciation. To date, however, statistical tools to incorporate species age into likelihood-based phylogenetic inference have been lacking. We present here a computational framework to quantify age-dependent extinction through maximum likelihood parameter estimation based on phylogenetic trees, assuming species lifetimes are gamma distributed. Testing on simulated trees shows that neglecting age dependence...

Data from: Age-dependent speciation can explain the shape of empirical phylogenies

Oskar Hagen, Klaas Hartmann, Mike Steel & Tanja Stadler
Tens of thousands of phylogenetic trees, describing the evolutionary relationships between hundreds of thousands of taxa, are readily obtainable from various databases. From such trees inferences can be made about the underlying macroevolutionary processes, yet remarkably these processes are still poorly understood. Simple and widely used evolutionary null models are problematic: empirical trees show very different imbalance between the sizes of the daughter clades of ancestral taxa compared to what models predict. Obtaining a simple...

Data from: Fish population genetic structure shaped by hydroelectric power plants in the upper Rhine catchment

Alexandre Gouskov, Marta Reyes, Lisa Wirthner-Bitterlin & Christoph Vorburger
The Rhine catchment in Switzerland has been transformed by a chain of hydroelectric power stations. We addressed the impact of fragmentation on the genetic structure of fish populations by focusing on the European chub (Squalius cephalus). This fish species is not stocked and copes well with altered habitats, enabling an assessment of the effects of fragmentation per se. Using microsatellites, we genotyped 2133 chub from 47 sites within the catchment fragmented by 37 hydroelectric power...

Data from: Invasiveness of plant pathogens depends on the spatial scale of host distribution

Alexey Mikaberidze, Christopher C. Mundt & Sebastian Bonhoeffer
Plant diseases often cause serious yield losses in agriculture. A pathogen’s invasiveness can be quantified by the basic reproductive number, R0. Since pathogen transmission between host plants depends on the spatial separation between them, R0 is strongly influenced by the spatial scale of the host distribution.We present a proof of principle of a novel approach to estimate the basic reproductive number, R0, of plant pathogens as a function of the size of a field planted...

Data from: Hidden diversity in the freshwater planktonic diatom Asterionella formosa

Silke Van Den Wyngaert, Markus Möst, Remo Freimann, Bastiaan W. Ibelings & Piet Spaak
Many freshwater and marine algal species are described as having cosmopolitan distributions. Whether these widely distributed morphologically similar algae also share a similar gene pool remains often unclear. In the context of island biogeography theory, stronger spatial isolation deemed typical of freshwater lakes should restrict gene flow and lead to higher genetic differentiation among lakes. Using nine microsatellite loci, we investigate the genetic diversity of a widely distributed freshwater planktonic diatom, Asterionella formosa, across different...

Data from: Stoichiometric imbalances between detritus and detritivores are related to shifts in ecosystem functioning

André Frainer, Jérémy Jabiol, Mark O. Gessner, Andreas Bruder, Eric Chauvet, Brendan McKie & Brendan G. McKie
How are resource consumption and growth rates of litter-consuming detritivores affected by imbalances between consumer and litter C:N:P ratios? To address this question, we offered leaf litter as food to three aquatic detritivore species, which represent a gradient of increasing body N:P ratios: a crustacean, a caddisfly and a stonefly. The detritivores were placed in microcosms and submerged in a natural stream. Four contrasting leaf species were offered, both singly and in two-species mixtures, to...

Data from: Total-evidence dating under the fossilized birth-death process

Chi Zhang, Tanja Stadler, Seraina Klopfstein, Tracy A. Heath & Fredrik Ronquist
Bayesian total-evidence dating involves the simultaneous analysis of morphological data from the fossil record and morphological and sequence data from recent organisms, and it accommodates the uncertainty in the placement of fossils while dating the phylogenetic tree. Due to the flexibility of the Bayesian approach, total-evidence dating can also incorporate additional sources of information. Here, we take advantage of this and expand the analysis to include information about fossilization and sampling processes. Our work is...

Data from: Sexual selection protects against extinction

Alyson J. Lumley, Łukasz Michalczyk, James J. N. Kitson, Lewis G. Spurgin, Catriona A. Morrison, Joanne L. Godwin, Matthew E. Dickenson, Oliver Y. Martin, Brent C. Emerson, Tracey Chapman & Mattew J. G. Gage
Reproduction through sex carries substantial costs, mainly because only half of sexual adults produce offspring. It has been theorized that these costs could be countered if sex allows sexual selection to clear the universal fitness constraint of mutation load. Under sexual selection, competition between (usually) males and mate choice by (usually) females create important intraspecific filters for reproductive success, so that only a subset of males gains paternity. If reproductive success under sexual selection is...

Data from: Local adaptation at range edges: comparing elevation and latitudinal gradients

Aud H. Halbritter, Regula Billeter, Peter J. Edwards & Jake M. Alexander
Local adaptation at range edges influences species’ distributions and how they respond to environmental change. However, the factors that affect adaptation, including gene flow and local selection pressures, are likely to vary across different types of range edge. We performed a reciprocal transplant experiment to investigate local adaptation in populations of Plantago lanceolata and P. major from central locations in their European range and from their latitudinal and elevation range edges (in northern Scandinavia and...

Data from: The contrasting phylodynamics of human influenza B viruses

Dhanasekaran Vijaykrishna, Edward C. Holmes, Udayan Joseph, Mathieu Fourment, Yvonne C. F. Su, Rebecca Halpin, Raphael T. C. Lee, Yi-Mo Deng, Vithiagaran Gunalan, Xudong Lin, Tim Stockwell, Nadia B. Fedorova, Bin Zhou, Natalie Spirason, Denise K. Kühnert, Veronika Bošková, Tanja Stadler, Anna-Maria Costa, Dominic E. Dwyer, Q. Sue Huang, Lance C. Jennings, William Rawlinson, Sheena G. Sullivan, Aeron C. Hurt, Sebastian Maurer-Stroh … & Raphael TC Lee
A complex interplay of viral, host and ecological factors shape the spatio-temporal incidence and evolution of human influenza viruses. Although considerable attention has been paid to influenza A viruses, a lack of equivalent data means that an integrated evolutionary and epidemiological framework has until now not been available for influenza B viruses, despite their significant disease burden. Through the analysis of over 900 full genomes from an epidemiological collection of more than 26,000 strains from...
