Data from: General and species-specific impacts of a neonicotinoid insecticide on the ovary development and feeding of wild bumblebee queensGemma L. Baron, Nigel E. Raine, Mark J.F. Brown & Mark J. F. Brown
Bumblebees are essential pollinators of crops and wild plants, but are in decline across the globe. Neonicotinoid pesticides have been implicated as a potential driver of these declines, but most of our evidence base comes from studies of a single species. There is an urgent need to understand whether such results can be generalized across a range of species. Here, we present results of a laboratory experiment testing the impacts of field-relevant doses (1.87–5.32 ppb)...
Data from: The effects of sub-curative praziquantel treatment on life-history traits and trade-offs in drug-resistant Schistosoma mansoniMafalda Viana, Christina L. Faust, Dan T. Haydon, Joanne P. Webster, Poppy H. L. Lamberton & Daniel T. Haydon
Natural selection acts on all organisms, including parasites, to maximise reproductive fitness. Drug resistance traits are often associated with life-history costs in the absence of treatment. Schistosomiasis control programmes rely on mass drug administration to reduce human morbidity and mortality. Although hotspots of reduced drug efficacy have been reported, resistance is not widespread. Using Bayesian State-Space Models (SSMs) fitted to data from an in vivo laboratory system, we tested the hypothesis that the spread of...
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...
Data from: Assessment of healthcare delivery in the early management of bacterial meningitis in UK young infants: an observational studyIfeanyichukwu O. Okike, Shamez N. Ladhani, Mark Anthony, Nelly Ninis & Paul T. Heath
OBJECTIVE: To define early presenting features of bacterial meningitis in young infants in England and to review the adequacy of individual case management as compared with relevant national guidelines and an expert panel review. DESIGN: Retrospective medical case note review and parental recall using standardised questionnaires. SETTING: England and Wales. PARTICIPANTS: Infants aged <90 days with bacterial meningitis diagnosed between July 2010 and July 2013. RESULTS: Of the 97 cases recruited across England and Wales,...
Data from: Argentine ants (Linepithema humile) use adaptable transportation networks to track changes in resource qualityTanya Latty, Michael J. Holmes, James C. Makinson & Madeleine Beekman
Transportation networks play a crucial role in human and animal societies. For a transportation network to be efficient, it must have adequate capacity to meet traffic demand. Network design becomes increasingly difficult in situations where traffic demand can change unexpectedly. In humans, network design is often constrained by path dependency because it is difficult to move a road once it is built. A similar issue theoretically faces pheromone-trail-laying social insects; once a trail has been...
Data from: Tempo and mode of performance evolution across multiple independent origins of adhesive toe pads in lizardsTravis Jay Hagey, Josef C. Uyeda, Kristen E. Crandell, Jorn A. Cheney, Kellar Autumn & Luke J. Harmon
Understanding macroevolutionary dynamics of trait evolution is an important endeavor in evolutionary biology. Ecological opportunity can liberate a trait as it diversifies through trait space, while genetic and selective constraints can limit diversification. While many studies have examined the dynamics of morphological traits, diverse morphological traits may yield the same or similar performance and as performance is often more proximately the target of selection, examining only morphology may give an incomplete understanding of evolutionary dynamics....
Data from: Gaze-contingent reinforcement learning reveals incentive value of social signals in young children and adultsAngélina Vernetti, Tim J. Smith & Atsushi Senju
While numerous studies have demonstrated that infants and adults preferentially orient to social stimuli, it remains unclear as to what drives such preferential orienting. It has been suggested that the learned association between social cues and subsequent reward delivery might shape such social orienting. Using a novel, spontaneous indication of reinforcement learning (with the use of a gaze contingent reward-learning task), we investigated whether children and adults' orienting towards social and non-social visual cues can...
Data from: Long-term balancing selection on chromosomal variants associated with crypsis in a stick insectDorothea Lindtke, Kay Lucek, Victor Soria-Carrasco, Romain Villoutreix, Timothy E. Farkas, Rüdiger Riesch, Stuart R. Dennis, Zach Gompert & Patrik Nosil
How polymorphisms are maintained within populations over long periods of time remains debated, because genetic drift and various forms of selection are expected to reduce variation. Here, we study the genetic architecture and maintenance of phenotypic morphs that confer crypsis in Timema cristinae stick insects, combining phenotypic information and genotyping-by-sequencing data from 1360 samples across 21 populations. We find two highly divergent chromosomal variants that span megabases of sequence and are associated with color polymorphism....
The cryptocurrency market surpassed the barrier of $100 billion market capitalization in June 2017, after months of steady growth. Despite its increasing relevance in the financial world, a comprehensive analysis of the whole system is still lacking, as most studies have focused exclusively on the behaviour of one (Bitcoin) or few cryptocurrencies. Here, we consider the history of the entire market and analyse the behaviour of 1469 cryptocurrencies introduced between April 2013 and May 2017....
Data from: Ageing and agency: age-related changes in susceptibility to illusory experiences of controlMaria Cristina Cioffi, Gianna Cocchini, Michael J. Banissy & James W. Moore
Sense of agency (SoAg) is the feeling of control over one's actions and their effects. It can be augmented or attenuated by internal signals and by external cues. Research has shown a reduction in the SoAg in older adulthood, but the reasons behind this change remain unclear. We investigated agency processing differences that may underpin age-related changes in SoAg. Using a modified version of a vicarious agency paradigm, we tested the modulation of SoAg by...
Data from: A game-theoretical model of kleptoparasitic behaviour in an urban gull (Laridae) population.Robert Spencer & Mark Broom
Kleptoparasitism (food stealing) is a significant behaviour for animals that forage in social groups as it permits some individuals to obtain resources whilst avoiding the costs of searching for their own food. Evolutionary game theory has been used to model kleptoparasitism, with a series of differential equation based compartmental models providing significant theoretical insights into behaviour in kleptoparasitic populations. In this paper we apply this compartmental modelling approach to kleptoparasitic behaviour in a real foraging...
