Charlie Bucket effect datasets

Petr Tureček, Alice Velková & Jan Havlíček
Data used in the article One but not two grandmothers increased child survival in poorer families in west Bohemian population Human childrearing is characterized by cooperative care and grandmothers are usually the most prominent alloparents. Nevertheless, it has been argued that limited resources may intensify competition among kin. The effect of grandmothers’ presence on child survival may thus crucially depend on the family’s socioeconomic status. We evaluate the impact of grandmothers’ presence on child survival...

Greater reproductive assurance of asexual plant compared to sexual relative in a low density sympatric population – experimental evidence for pollen limitation

Patrik Mráz & Viera Mrázová
This dataset contains data from a common garden experiment described in the paper: “Mráz P, Mrázová V. 2021. Greater reproductive assurance of asexual plant compared to sexual relative in a low density sympatric population – experimental evidence for pollen limitation. Journal of Evolutionary Ecology ”. We compared the level and stability of reproductive assurance between sexual self-incompatible and asexual autonomously apomictic plants of Hieracium alpinum (Asteraceae) cultivated in a sympatric low-density population with two levels...

Data from: Evolutionary–phylogenetic pathway of the Cretaceous ammonite genus Aegocrioceras and its relationship to Juddiceras spp. and Crioceratites spp.

Manuel F. G. Weinkauf, René Hoffmann & Kurt Wiedenroth
The systematics of ammonoids are complicated by their large degree of intra-specific variation, which complicates a stable validation of species. Aegocrioceras is a heteromorph ammonite from the Lower Saxony Basin in the Hauterivian Boreal, and a prime example of a genus with an unstable internal systematic and external relationship to other ammonoids. Here, we use quantitative morphometrics on Aegocrioceras species from an assemblage collected in the clay pit Resse (north-west Germany) to evaluate the systematics...

Data from: Re-examination of species limits in Aspergillus section Flavipedes using advanced species delimitation methods and description of four new species

František Sklenář, Željko Jurjević, Jos Houbraken, Miroslav Kolařík, Maiken Cavling Arendrup, Karin Meinike Jørgensen, Joao Paulo Zen Siqueira, Josepa Gené, Takashi Yaguchi, Chibundu Ngozi Ezekiel, Cristina Silva Pereira & Vít Hubka
Since the last revision in 2015, the taxonomy of section Flavipedes evolved rapidly along with the availability of new species delimitation techniques. This study aims to re-evaluate the species boundaries of section Flavipedes members using modern delimitation methods applied to an extended set of strains (n=90) collected from various environments. The analysis used DNA sequences of three house-keeping genes (benA, CaM, RPB2) and consisted of two steps: application of several single-locus (GMYC, bGMYC, PTP, bPTP)...

Data from: Spectroscopic approach to correction and visualisation of bright-field light transmission microscopy biological data

Ganna Platonova, Dalibor Štys, Pavel Souček, Kirill Lonhus, Jan Valenta & Renata Rychtáriková
The most realistic information about the transparent sample such as a live cell can be obtained only using bright-field light microscopy. At high-intensity pulsing LED illumination, we captured a primary 12-bit-per-channel (bpc) response from an observed sample using a bright-field wide-field microscope equipped with a high-resolution (4872x3248) image sensor. In order to suppress data distortions originating from the light interactions with undesirable elements in the optical path, poor sensor reproduction (geometrical defects of the camera...

Data from: The genetic regulation of avian migration timing: combining candidate genes and quantitative genetic approaches in a long-distance migrant

Miloš Krist, Pavel Munclinger, Martins Briedis & Peter Adamík
Plant and animal populations can adapt to prolonged environmental changes if they have sufficient genetic variation in important phenological traits. The genetic regulation of annual cycles can be studied either via candidate genes or through the decomposition of phenotypic variance by quantitative genetics. Here we combined both approaches to study the timing of migration in a long-distance migrant, the collared flycatcher (Ficedula albicollis). We found that none of the four studied candidate genes (CLOCK, NPAS2,...

Discovery of new Trichophyton members, T. persicum and T. spiraliforme spp. nov., as a cause of highly inflammatory tinea cases in Iran and Czechia

Adéla Čmoková, Ali Rezaei-Matehkolaei, Ivana Kuklová, Miroslav Kolařík, Forough Shamsizadeh, Saham Ansari, Maral Gharaghani, Viera Miňovská, Mohammad Javad Najafzadeh, Sadegh Nouripour‐Sisakht, Takashi Yaguchi, Kamiar Zomorodian, Hossein Zarrinfar & Vit Hubka
Pathogens from the Trichophyton benhamiae complex are one of the most important causes of animal mycoses with significant zoonotic potential. In the light of the recently revised taxonomy of this complex, we retrospectively identified 38 Trichophyton isolates that could not be resolved in any of the existing species. These strains were isolated from Iranian and Czech patients during molecular epidemiological surveys on dermatophytosis and were predominantly associated with highly inflammatory tinea corporis cases suggesting possible...

Divergent sexual signals reflect costs of local parasites

Amanda Hund, Joanna K. Hubbard, Tomáš Albrecht, Yoni Vortman, Pavel Munclinger, Simona Krausová, Oldřich Tomášek & Rebecca J. Safran
Many closely related populations are distinguished by variation in sexual signals and this variation is hypothesized to play an important role in reproductive isolation and speciation. Within populations, there is considerable evidence that sexual signals provide information about the incidence and severity of parasite infections, but it remains unclear if variation in parasite communities across space could play a role in initiating or maintaining sexual trait divergence. To test for variation in parasite-associated selection, we...

Pollinators adjust their behavior to presence of pollinator-transmitted pathogen in plant population

Klára Koupilová, Jakub Štenc & Zdeněk Janovský
Interactions between pollinators and plants can be affected by the presence of plant pathogens that substitute their infectious propagules for pollen in flowers and rely on pollinators for transmission to new hosts. However, it is largely unknown how pollinators integrate cues from diseased plants such as altered floral rewards and floral traits, and how their behavior changes afterward. Understanding pollinator responses to diseased plants is crucial for predicting both pathogen transmission and pollen dispersal in...

Weak coordination between leaf drought tolerance and proxy traits in herbaceous plants

Maria Májeková, Tomáš Hájek, Agnes J. Albert, Francesco De Bello, Jiří Doležal, Lars Götzenberger, Stepan Janeček, Jan Lepš, Pierre Liancourt & Ondrej Mudrák
Increased drought is predicted to have a major impact on plant performance under environmental change. Yet leaf hydraulic traits directly related to drought tolerance, such as leaf turgor loss point (πtlp), are underrepresented in trait-based studies and have been largely overlooked within the main frameworks evaluating trait–trait coordination and trade-offs: the leaf economics spectrum and the global spectrum of plant form and function. Using 122 herbaceous species from the Central European temperate grasslands, we investigated...

Evaluating the potential effects of capturing and handling on subsequent observations of a migratory passerine through individual acoustic monitoring

Tereza Petrusková, Hana Kahounová, Iveta Pišvejcová, Anna Čermáková, Tomáš Brinke, Niall H. K. Burton & Adam Petrusek
Ringing is the most common technique used for individual marking of passerine birds, informing understanding of many aspects of their behaviour and ecology. Birds caught for ringing may also be substantially handled before release (e.g., to obtain biometric data, blood or feather samples), and all such procedures may affect the subsequent behaviour of a captured individual. Previous field studies that have assessed the potential effects of capturing and handling birds have nevertheless, to date, lacked...

No evidence for a role of trills in male response to territorial intrusion in a complex singer, the Thrush Nightingale

Abel Souriau, Radka Reifová, Adam Petrusek & Tereza Petrusková
Among the broad diversity of songbird vocalisations, song can serve a wide range of different functions depending on the species and context. In many species, aggressive motivation has often been linked with the use of fast repeated series of elements typically referred to as trills. However, only a few studies explored the role of this specific component in species with a large repertoire and high song complexity. Here, we investigate the potential role of trills...

Genetics of quantitative traits with dominance under stabilizing and directional selection in partially selfing species

Josselin CLO & Øystein Opedal
Recurrent self-fertilization is thought to lead to reduced adaptive potential by decreasing the genetic diversity of populations, thus leading selfing lineages down an evolutionary ‘blind alley’. Though well supported theoretically, empirical support for reduced adaptability in selfing species is limited. One limitation of classical theoretical models is that they assume pure additivity of the fitness-related traits that are under stabilizing selection, despite ample evidence that quantitative traits are subject to dominance. Here we relax this...

Bird pollination syndrome is the plant’s adaptation to ornithophily, but nectarivorous birds are not so selective

Krystof Chmel, Francis Ewome, Guillermo Gómez, Yannick Klomberg, Jan Mertens, Robert Tropek & Štěpán Janeček
Many tropical plants are pollinated by birds and several bird phylogenetical lineages have specialised to a nectar diet. The long-assumed, intimate ecological and evolutionary relationship between ornithophilous plants and phenotypically specialised nectarivorous birds has nevertheless been questioned in recent decades, where such plant-pollinator interactions have been shown to be highly generalised. In our study, we analysed two extensive interaction datasets: bird-flower and insect-flower interactions, both collected on Mt. Cameroon, West-Central Africa. We tested if 1)...

Effects of high and low-efficacy therapy in secondary progressive multiple sclerosis

Izanne Roos, Emmanuelle Leray, Romain Casey, Dana Horakova, Eva Havrdova, Guillermo Izquierdo, Sara Eichau, Francesco Patti, Gilles Edan, Marc Debouverie, Jean Pelletier, Serkan Ozakbas, Maria Pia Amato, Pierre Clavelou, Pierre Grammond, Cavit Boz, Katherine Buzzard, Olga Skibina, Jonathan Ciron, Oliver Gerlach, Francois Grand'Maison, Jeannette Lechner-Scott, Charles Malpas, Helmut Butzkueven, Sandra Vukusic … & Tomas Kalincik
Objective: To compare the clinical effectiveness of high- and low-efficacy treatments in patients with recently active and inactive secondary progressive multiple sclerosis (SPMS) after accounting for therapeutic lag. Methods: Patients treated with high- (natalizumab, alemtuzumab, mitoxantrone, ocrelizumab, rituximab, cladribine, fingolimod) or low-efficacy (interferon β, glatiramer acetate, teriflunomide) therapies after SPMS onset were selected from MSBase and OFSEP, two large observational cohorts. Therapeutic lag was estimated for each patient based on their demographic and clinical characteristics....

Sunbirds' tendency to hover: the roles of energetic rewards, inflorescence architecture and rain - data

Zuzana Sejfová, Jiří Mlíkovský, Francis Luma Ewome, Petra Janečková, Yannick Klomberg, Marcus Njie & Štěpán Janeček
Although the Old World sunbirds are generally considered to be an ecological analogue of the New World hummingbirds, it is commonly believed that in contrast to hummingbirds, sunbirds perch while feeding. Nevertheless, recent studies have shown that Old World nectarivores hover while feeding more frequently than previously thought, and some Old World plants seem to have adapted to hovering bird pollinators. To reveal the importance of sunbird foraging behavior in nectar acquisition and to test...

Input data for estimating dimensionless number (Reynolds, Swimming and Strouhal number) of swimming penguin

Mahadi Masud, Marco La Mantia & Peter Dabnichki
Propulsion performance of swimming and flying animals is often evaluated by using dimensionless numbers, such as the Strouhal and Reynolds numbers. They have been shown to allow better understanding of locomotion efficiency, using relatively simple approaches and avoiding overly complex computational models. Specifically, it has been reported that efficient propulsion is more likely to occur when Strouhal number values – estimated from propulsive frequencies and amplitudes – are within a relatively narrow range, depending on...

Longitudinal evidence for immunosenescence and inflammaging in free-living great tits

Martin Těšický, Tereza Krajzingrová, Zuzana Świderská, Kamila Syslová, Barbora Bílková, Jiří Eliáš, Hana Velová, Jana Svobodová, Petra Bauerová, Tomáš Albrecht & Vinkler Michal
The first-line effector mechanisms of immune defence, including inflammation and oxidative burst, contribute significantly to host-pathogen resistance. Whether these immune responses undergo age-related changes in birds remains unknown. Here, we tracked selected inflammatory parameters in 54 free-living great tits (Parus major) of known age, captured repeatedly over three consecutive years, with the aims to investigate long-term repeatability and age-dependent changes in cellular oxidative burst responsiveness upon in vitro stimulation with bacterial lipopolysaccharide (LPS), and to...

Fitness consequences of hybridization in a predominantly selfing species: insights into the role of dominance and epistatic incompatibilities

Josselin Clo, Joëlle Ronfort & Laurène Gay
Studying the consequences of hybridization on plant performance is insightful to understand the adaptive potential of populations, notably at local scales. Due to reduced effective recombination, predominantly selfing species are organized in highly homozygous multi-locus-genotypes (or lines) that accumulate genetic differentiation both among- and within-populations. This high level of homozygosity facilitates the dissection of the genetic basis of hybrid performance in highly selfing species, which gives insights into the mechanisms of reproductive isolation between lines....

Inter-annual repeatability and age-dependent changes in plasma testosterone levels in a longitudinally monitored free-living passerine bird

Martin Těšický, Tereza Krajzingrová, Jiří Eliáš, Hana Velová, Jana Svobodová, Petra Bauerová, Tomáš Albrecht & Michal Vinkler
While seasonal trends in testosterone levels are known from cross-cohort studies, data on testosterone inter-annual individual repeatability in wild birds are rare. Also, our understanding of hormonal age-dependent changes in testosterone levels is limited. We assessed plasma testosterone levels in 105 samples originating from 49 repeatedly captured free-living great tits (Parus major) sampled during the nesting to investigate their relative long-term repeatability and within-individual changes. Furthermore, we examined the inter-annual repeatability of condition-related traits (carotenoid-...

Data from: Evolution of flexible biting in hyperdiverse parasitoid wasps

Thomas Van De Kamp, István Mikó, Arnold H. Staniczek, Benjamin Eggs, Daria Bajerlein, Tomáš Faragó, Lea Hagelstein, Elias Hamann, Rebecca Spiecker, Tilo Baumbach, Petr Janšta & Lars Krogmann
One key event in insect evolution was the development of mandibles with two joints, which allowed powerful biting, but restricted their movement to a single degree of freedom. These mandibles define the Dicondylia, which constitute over 99 percent of all extant insect species. It was common doctrine that the dicondylic articulation of chewing mandibles remained unaltered for more than 400 million years. We report highly modified mandibles overcoming the restrictions of a single degree of...

Reconstructing squamate biogeography in Afro-Arabia reveals the influence of a complex and dynamic geologic past

Héctor Tejero-Cicuéndez, Austin H. Patton, Daniel S. Caetano, Jiří Šmíd, Luke J. Harmon & Salvador Carranza
The geographic distribution of biodiversity is central to understanding evolutionary biology. Paleogeographic and paleoclimatic histories often help to explain how biogeographic patterns unfold through time. However, such patterns are also influenced by a variety of other factors, such as lineage diversification, that may affect the probability of certain types of biogeographic events. The complex and well-known geologic and climatic history of Afro-Arabia, together with the extensive research on reptile systematics in the region, makes Afro-Arabian...

A supergene underlies linked variation in color and morphology in a Holarctic songbird

Erik Funk, Nicholas Mason, Snæbjörn Pálsson, Tomáš Albrecht, Jeff Johnson & Scott Taylor
The genetic architecture of a phenotype can have considerable effects on the evolution of a trait or species. Characterizing genetic architecture provides insight into the complexity of a given phenotype and, potentially, the role of the phenotype in evolutionary processes like speciation. We use genome sequences to investigate the genetic basis of phenotypic variation in redpoll finches (Acanthis spp.). We demonstrate that variation in redpoll phenotype is broadly controlled by a ~55-Mb chromosomal inversion. Within...
