Data from: Multilocus phylogeography of the European ground squirrel: cryptic interglacial refugia of continental climate in Europe

Štěpánka Říčanová, Yordan Koshev, Oldřich Říčan, Nada Ćosić, Duško Ćirović, František Sedláček & Josef Bryja
The theory of classical and cryptic Pleistocene refugia is based mainly on historical changes in temperature, and the refugia are usually defined within a latitudinal gradient. However, the gradient of oceanic–continental climate (i.e. longitudinal) was also significantly variable during glacial cycles with important biotic consequences. Range-wide phylogeography of the European ground squirrel (EGS) was used to interpret the evolutionary and palaeogeographical history of the species in Europe and to shed light on its glacial–interglacial dynamic....

Data from: Forest snail faunas from Crimea (Ukraine), an isolated and incomplete Pleistocene refugium

Robert A. D. Cameron, Beata M. Pokryszko & Michal Horsák
The land snail faunas of 26 forest sites and two open rocky sites in the Crimean Mountains were sampled in 2011. Of the 40 species found within the forests (about half the known fauna of Crimea as a whole), 28 were species with wide western Palaearctic distributions, and only eight were endemic to Crimea. While there were significant differences in the faunas of different sampling areas, these seemed to be a consequence of ecological differences...

Data from: Venom of prey-specialised spiders is more toxic to their preferred prey: a result of prey-specific toxins

Stano Pekar, Eva Liznarova, Ondrej Bocanek & Zbynek Zdrahal
1. In specialised predators a variety of adaptations have evolved to such a level of specificity that they allow very effective exploitation of focal prey. Venom is an essential adaptive trait of predatory venomous species, such as spiders, yet our knowledge of spider venom is incomplete. 2. In agreement with the prey preference hypothesis, we expected that the venom of spider specialists should be more toxic to focal than to alternative prey, because it is...

Data from: At the Central European – Balkan transition: forest land snail faunas of the Banat contrasted with those of the Carpathian chain

Robert A. D. Cameron, Beata M. Pokryszko, Voichita Gheoca & Michal Horsák
Twenty-nine forest sites in six sampling areas in the Banat region of Romania, adjacent to Serbia, were sampled to obtain inventories of their snail faunas and to make comparisons between these and previously studied faunas in the mountains from the Sudetes in the north-west to the Southern Transylvanian Carpathians in the south. 65 species were recorded overall, with between 13 and 33 at individual sites. Among the six sampling areas that on Schist rock at...

Data from: Patterns of selection on Plasmodium falciparum erythrocyte binding antigens after the colonisation of the New World

Erhan Yalcindag, Virginie Rougeron, Eric Elguero, Céline Arnathau, Patrick Durand, Sylvain Brisse, Laure Diancourt, Agnes Aubouy, Pierre Becquart, Umberto D'Alessandro, Didier Fontenille, Dionicia Gamboa, Amanda Maestre, Didier Ménard, Lise Musset, Oscar Noya, Vincent Veron, Albina Wide, Bernard Carme, Eric Legrand, Christine Chevillon, Francisco J. Ayala, François Renaud & Franck Prugnolle
Pathogens, which have recently colonized a new host species or new populations of the same host, are interesting models for understanding how populations may evolve in response to novel environments. During its colonization of South America from Africa Plasmodium falciparum, the main agent of malaria, has been exposed to new conditions in distinctive new human populations (Amerindian and populations of mixed origins), that likely exerted new selective pressures on the parasite's genome. Among the genes...

Data from: Multi-speed genome diploidization and diversification after an ancient allopolyploidization

Terezie Mandáková, Milan Pouch, Klára Harmanová, Shing Hei Zhan, Itay Mayrose & Martin A. Lysak
Hybridization and genome doubling (allopolyploidy) have led to evolutionary novelties as well as to the origin of new clades and species. Despite the importance of allopolyploidization, the dynamics of post-polyploid diploidization (PPD) at the genome level has been only sparsely studied. The Microlepidieae (MICR) is a crucifer tribe of 17 genera and c. 56 species endemic to Australia and New Zealand. Our phylogenetic and cytogenomic analyses revealed that MICR originated via an inter-tribal hybridization between...

Data from: Complex patterns of host switching in New World Arenaviruses

Nancy R. Irwin, Michaela Bayerlová, Olivier Missa & Natália Martínková
We empirically tested the long-standing hypothesis of codivergence of New World arenaviruses (NWA) with their hosts. We constructed phylogenies for NWA and all known hosts and used them in reconciliation analyses. We also constructed a phylogenetic tree of all Sigmodontinae and Neotominae rodents and tested whether viral–host associations were phylogenetically clustered. We determined host geographical overlap to determine to what extent opportunity to switch hosts was limited by host relatedness or physical proximity. With the...

Data from: Trait-dependent distributional shifts in fruiting of common British fungi

Alan C. Gange, Einar Heegaard, Lynne Boddy, Carrie Andrew, Paul Kirk, Rune Halvorsen, Thomas W. Kuyper, Claus Bässler, Jeffrey Diez, Jacob Heilman-Clausen, Klaus Høiland, Ulf Büntgen & Håvard Kauserud
Despite the dramatic phenological responses of fungal fruiting to recent climate warming, it is unknown whether spatial distributions of fungi have changed and to what extent such changes are influenced by fungal traits, such as ectomycorrhizal (ECM) or saprotrophic lifestyles, spore characteristics, or fruit body size. Our overall aim was to understand how climate and fungal traits determine whether and how species-specific fungal fruit body abundances have shifted across latitudes over time, using the UK...

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

Rachel Stubbington, Romain Sarremejane, Alex Laini, Núria Cid, Zoltán Csabai, Judy England, Antoni Munné, Tom Aspin, Núria Bonada, Daniel Bruno-Collados, Sophie Cauvy-Fraunie, Richard Chadd, Claudia Dienstl, Pau Fortuño, Wolfram Graf, Cayetano Gutiérrez-Cánovas, Andy House, Ioannis Karaouzas, Eleana Kazila, Andrés Millán, Maria Morais, Petr Pařil, Alex Pickwell, Marek Polášek, David Sánchez-Fernández … & Thibault Datry
1. Rivers are dynamic ecosystems in which both human impacts and climate-driven drying events are increasingly common. These anthropogenic and natural stressors interact to influence the biodiversity and functioning of river ecosystems. Disentangling ecological responses to these interacting stressors is necessary to guide management actions that support ecosystems adapting to global change. 2. We analysed the independent and interactive effects of human impacts and natural drying on aquatic invertebrate communities—a key biotic group used to...

Data from: Transformational mimicry in a myrmecomorphic spider

Stano Pekar, Yunyun Tsai & Michalko Radek
Species which are Batesian mimics during post-embryonic development shift between mimetic models as they grow in size. However, it has not yet been tested whether these successive mimetic phenotypes are similarly protected from predators. Early instar phenotypes could represent an inaccurate phenotype or an accurate phenotype because of selection from different predators. Here, we tested the hypotheses of transformational Batesian mimicry in the ant-mimicking jumping spider Leptochestes berolinensis . We quantified the mimetic accuracy of...

Data from: The evolution of dual meat and milk cattle husbandry in Linearbandkeramik societies

Rosalind E. Gillis, Lenka Kovačiková, Stéphanie Brehard, Emilie Guthmann, Ivana Vostrovská, Hana Nohálová, Rose-Marie Arbogast, László Domboróczki, Joachim Pechtl, Alexandra Anders, Arkadiusz Marciniak, Anne Tresset & Jean-Denis Vigne
Cattle dominate archaeozoological assemblages from the north-central Europe between the sixth and fifth millennium BC and are frequently considered as exclusively used for their meat. Dairy products may have played a greater role than previously believed. Selective pressure on the lactase persistence mutation has been modelled to have begun between 6000 and 4000 years ago in central Europe. The discovery of milk lipids in late sixth millennium ceramic sieves in Poland may reflect an isolated...

Data from: Inbreeding depression of sperm traits in the zebra finch Taeniopygia guttata

Pavlína Opatová, Malika Ihle, Jana Albrechtová, Oldřich Tomášek, Bart Kempenaers, Wolfgang Forstmeier & Tomáš Albrecht
Inbreeding depression, or the reduction in fitness due to mating between close relatives, is a key issue in biology today. Inbreeding negatively affects many fitness-related traits, including survival and reproductive success. Despite this, very few studies have quantified the effects of inbreeding on vertebrate gamete traits under controlled breeding conditions using a full-sib mating approach. Here, we provide comprehensive evidence for the negative effect of inbreeding on sperm traits in a bird, the zebra finch...

Data from: Philip Grime's fourth corner: are there plant species adapted to high disturbance and low productivity?

Tomas Herben, Jitka Klimešová & Milan Chytrý
Grime's CSR species life-strategy theory (competition-stress-ruderality) provides a conceptual framework to classify species into competitive (high productivity, low disturbance), stress-tolerant (low productivity, low disturbance) and ruderal (high productivity, high disturbance). Importantly, this classification is based on the assumption that the niche space of disturbance and productivity is filled unevenly: while in productive habitats species can adapt to different disturbance regimes, species of low-productivity and disturbed habitats do not exist, resulting in a triangular distribution of...

Data from: Alternative intrapopulation life history strategies and their trade-offs in an African annual fish

Matej Polačik, Radim Blažek, Radomil Řežucha, Milan Vrtílek, Eva Terzibasi-Tozzini & Martin Reichard
In ephemeral habitats, the same genotypes cope with unpredictable environmental conditions, favouring the evolution of developmental plasticity and alternative life-history strategies (ALHS). We tested the existence of intrapopulation ALHS in an annual killifish, Nothobranchius furzeri, inhabiting temporary pools. The pools are either primary (persisting throughout the whole rainy season) or secondary (refilled after desiccation of the initial pool), representing alternative niches. The unpredictable conditions led to the evolution of reproductive bet-hedging with asynchronous embryonic development....

Data from: Cross-sectional study of patients with axial spondyloarthritis fulfilling imaging arm of ASAS classification criteria: baseline clinical characteristics and subset differences in a single centre cohort

Objective: This study compared demographic, clinical and laboratory characteristics between patients with radiographic and non-radiographic axSpA. Methods: In this single centre cross-sectional study a total of 246 patients with axSpA fulfilling the imaging arm of ASAS classification criteria were recruited. A total of 140 patients were diagnosed as nr-axSpA, and 106 patients had AS. Sociodemographic characteristics, disease manifestations, clinical and laboratory disease activity and their differences between subsets were analysed. P values below 0.05 with...

Data from: Biological control in winter: novel evidence for the importance of generalist predators

Stano Pekar, Radek Michalko, Pamela Loverre, Eva Líznarová & Ľudmila Černecká
1. The role of generalist predators in pest control has been neglected because generalists are not able to track pest populations. Generalist predators are suggested to be important in spring before specialist predators become active. 2. Here, we show that some generalist predators are important even during winter, when the majority of arthropod pests and their enemies are dormant. We quantified the role of winter-active generalist predators on the suppression of pear psylla during winter...

Data from: Influence of interspecific competitors on behavioral thermoregulation: developmental or acute plasticity?

Barbora Winterová & Lumír Gvoždík
Many ectotherms reduce their exposure to changing thermal conditions using behavioral thermoregulation. The effectiveness of behavioral thermoregulation in maintaining ectotherm body temperatures within the target range is influenced not only by environmental (operative) temperatures but also by the presence of other con- and heterospecific individuals. How species’ interactions affect behavioral thermoregulation is largely unknown. Theory predicts that species’ interactions could affect the plasticity of behavioral thermoregulation in two ways, i.e. by developmental plasticity of a...
