Data from: Distribution of alien animal species richness in the Czech Republic

Radek Gebauer, Jan Divíšek, Miloš Buřič, Martin Večeřa, Antonín Kouba & Bořek Drozd
Biogeographical barriers formed by natural forces over billions of years have been substantially disrupted by human activity, particularly in recent centuries. In response to these anthropogenic changes, global homogenization of biota is observed at an ever‐increasing rate, causing environmental and economic losses as well as emerging health risks. Identifying factors underlying alien species richness is essential for prevention of future introductions and subsequent spread. In this study, we examined the effects of environmental and human‐related...

Data from: Venom gland size and venom complexity – essential trophic adaptations of venomous predators: a case study using spiders

Stano Pekár, Ondrej Bocanek, Ondrej Michalek, Lenka Petráková, Charles R. Haddad, Ondrej Sedo & Zbynek Zdrahal
Specialised predators possess variety of adaptations. In the venomous predators this may include size of the venom gland and venom composition. It is expected that due to different foraging strategies predators with a wide trophic niche (generalists) should possess larger venom glands that contain more diversified components than species with a narrow niche (specialists). We focused on spiders, as the most diversified group of venomous predators, in which a wide variety of trophic strategies has...

Data from: Fuel for the pace of life: baseline blood glucose concentration coevolves with life history traits in songbirds

Oldrich Tomasek, Lukas Bobek, Tereza Kralova, Marie Adamkova & Tomas Albrecht
1. It has been proposed that life histories have coevolved with a suite of physiological and behavioural adaptations, termed pace-of-life syndromes (POLS). Here, we hypothesise that basal concentration of blood glucose (G0), a major source of energy circulating in vertebrate blood, may constitute a key component of POLS. 2. To test this hypothesis, we measured G0 in 30 passerine species and tested its covariation with body mass and other life history traits. Importantly, body mass...

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: 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: 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: Explaining European fungal fruiting phenology with climate variability

Carrie Andrew, Einar Heegaard, Klaus Høiland, Beatrice Senn-Irlet, Thomas W. Kuyper, Irmgard Krisai-Greilhuber, Paul M. Kirk, Jacob Heilmann-Clausen, Alan C. Gange, Simon Egli, Claus Bässler, Ulf Büntgen, Lynne Boddy & Håvard Kauserud
Here we assess the impact of geographically dependent (latitude, longitude and altitude) changes in bioclimatic (temperature, precipitation and primary productivity) variability on fungal fruiting phenology across Europe. Two main nutritional guilds of fungi, saprotrophic and ectomycorrhizal, were further separated into spring and autumn fruiters. We used a path‐analysis to investigate how biogeographic patterns in fungal fruiting phenology coincided with seasonal changes in climate and primary production. Across central to northern Europe, mean fruiting varied by...

Data from: No trade-offs in interspecific interference ability and predation susceptibility in newt larvae

Monika Hlouskova, Monika Balogova, Veronika Krsakova & Lumír Gvoždík
Coexistence of species with similar requirements is allowed, among others, through trade-offs between competitive ability and other ecological traits. Although interspecific competition is based on two mechanisms, exploitation of resources and physical interference, trade-off studies largely consider only species’ ability to exploit resources. Using a mesocosm experiment, we examined the trade-off between interference competition ability and susceptibility to predation in larvae of two newt species, Ichthyosaura alpestris and Lissotriton vulgaris. In the presence of heterospecifics,...

Data from: The Aquilegia genome provides insight into adaptive radiation and reveals an extraordinarily polymorphic chromosome with a unique history

Danièle L. Filiault, Evangeline S. Ballerini, Terezie Mandakova, Gökçe Aköz, Nathan J. Derieg, Jeremy Schmutz, Jerry Jenkins, Jane Grimwood, Shengqiang Shu, Richard D. Hayes, Uffe Hellsten, Kerrie Barry, Juying Yan, Sirma Mihaltcheva, Miroslava Karafiatova, Viktoria Nizhynska, Elena M. Kramer, Martin A. Lysak, Scott A. Hodges & Magnus Nordborg
The columbine genus Aquilegia is a classic example of an adaptive radiation, involving a wide variety of pollinators and habitats. Here we present the genome assembly of A. coerulea 'Goldsmith', complemented by high-coverage sequencing data from 10 wild species covering the world-wide distribution. Our analyses reveal extensive allele sharing among species, and demonstrate that introgression and selection played a role in the Aquilegia radiation. We also present the remarkable discovery that the evolutionary history of...

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...
