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: 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: 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: A time-calibrated road map of Brassicaceae species radiation and evolutionary history

Nora Hohmann, Eva M. Wolf, Martin A. Lysak & Marcus A. Koch
The Brassicaceae include several major crop plants and numerous important model species in comparative evolutionary research such as Arabidopsis, Brassica, Boechera, Thellungiella, and Arabis species. As any evolutionary hypothesis needs to be placed in a temporal context, reliably dated major splits within the evolution of Brassicaceae are essential. We present a comprehensive time-calibrated framework with important divergence time estimates based on whole-chloroplast sequence data for 29 Brassicaceae species. Diversification of the Brassicaceae crown group started...

Data from: A skull might lie: modelling ancestral ranges and diet from genes and shape of tree squirrels

Patrícia Pečnerová, Jiří C. Moravec & Natália Martínková
Tropical forests of Central and South America represent hotspots of biological diversity. Tree squirrels of the tribe Sciurini are an excellent model system for the study of tropical biodiversity as these squirrels disperse exceptional distances, and after colonizing the tropics of the Central and South America, they have diversified rapidly. Here, we compare signals from DNA sequences with morphological signals using pictures of skulls and computational simulations. Phylogenetic analyses reveal step-wise geographic divergence across the...

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: 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: 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...

Data from: Resource availability, mating opportunity, and sexual selection intensity influence the expression of male alternative reproductive tactics

Paolo Giovanni Ghislandi, Stano Pekar, Magdalena Matzke, Sarah Schulte-Döinghaus, Trine Bilde, Cristina Tuni &
The expression of alternative reproductive tactics can be plastic and occur simultaneously depending on cues that vary spatially or temporally. For example, variation in resources and sexual selection intensity is expected to influence the pay-off of each tactic and shape the decision of which tactic to employ. Males of the nuptial gift-giving spider Pisaura mirabilis can adopt three tactics: offering a genuine prey gift, a ‘worthless’ non-nutritious gift, or no gift. We hypothesized that resources...

Data from: Postglacial determinants of regional species pools in alpine grasslands

What defines insularity for plants in edaphic islands?

Francisco Emmanuel Méndez Castro, Luisa Conti, Milan Chytrý, Borja Jimenez-Alfaro, Michal Hajek, Michal Horsák, David Zeleny, Marco Malavasi & Gianluigi Ottaviani
The Theory of Island Biogeography postulates that size and isolation are key drivers of biodiversity on islands. This theory has been applied not only to true (e.g. oceanic) islands but also to terrestrial island-like systems (e.g. edaphic islands). Recently, a debate has opened as to whether terrestrial island-like systems function like true islands. However, identifying the effect of insularity in terrestrial systems is conceptually and methodologically challenging because recognizing species source(s) and measuring isolation is...

Reliability and predictive validity of two scales of self-rated health in China: results from China Health and Retirement Longitudinal Study (CHARLS)

Yuwei Pan, Jitka Pikhartova, Martin Bobak & Hynek Pikhart
Abstract Background Despite the widespread use of the single item self-rated health (SRH) question, its reliability has never been evaluated in Chinese population. Methods We used data from the China Health and Retirement Longitudinal Study, waves 1–4 (2011–2019). In wave 1, the same SRH question was asked twice, separated by other questions, on a subset of 4533 subjects, allowing us to examine the test–retest reliability of SRH. In addition, two versions of SRH questions (the...

The evolutionary history of Cardamine bulbifera shows a successful rapid postglacial Eurasian range expansion in the absence of sexual reproduction

Marcus A. Koch, Yalu Ru, Terezie M. Mandáková & Martin A. Lysak
Background and Aims Sexual reproduction is known to drive plant diversification and adaptation. Here we investigate the evolutionary history and spatiotemporal origin of a dodecaploid (2n = 12x = 96) Eurasian deciduous woodland species, Cardamine bulbifera, which reproduces and spreads via vegetative bulb-like structures only. The species has been among the most successful range-expanding understorey woodland plants in Europe, which raises the question of the genetic architecture of its gene pool, since its hexaploid (2n...
