Data and R code from: Haemosporidian infections influence risk-taking behaviours in young male blackcaps Sylvia atricapilla
<p>This repository contains all data and code necessary to reproduce the results and figures of the paper:</p> <p>Remacha, C., Ramírez, A., Arriero, E. and Pérez-Tris, J. 2023. Haemosporidian infections influence risk-taking behaviours in young male blackcaps <em>Sylvia atricapilla</em>. Animal Behaviour, 196, 113-126. <a href="https://doi.org/10.1016/j.anbehav.2022.12.001">https://doi.org/10.1016/j.anbehav.2022.12.001</a></p> <p>The repository contains a readme file (README_SYAT_MS_ANIBEH_Scripts.txt) with a description of the code and the data. The code is organised in eight R script files. Instructions to run the code are provided in the readme file. The data are organised in two separate files. One file (SYAT_MS_BH_ANIBEHdata.txt) contains data of exploratory and antipredatory behaviours of 43 young male blackcaps. The other one (SYAT_MS_BH_BIOL_ANIBEHdata.txt) contains biological and experimental attributes of the same individuals: status and intensity of parasite infection, experimental treatment, morphology and body mass.</p>

Data from: Sex differences in the predictability of risk-taking behaviour
<p>Recent research has found that individuals often vary in how consistently they express their behaviour over time (i.e. behavioural predictability) and suggested that these individual differences may be heritable. However, little is known about the intrinsic factors that drive variation in the predictability of behaviour. Indeed, whether variation in behavioural predictability is sex-specific is not clear. This is important, as behavioural predictability has been associated with vulnerability to predation, suggesting that the predictability of behavioural traits may have key fitness implications. We investigated whether male and female eastern mosquitofish (Gambusia holbrooki) differed in the predictability of their risk-taking behaviour. Specifically, over a total of 954 behavioural trials, we repeatedly measured risk-taking behaviour with three commonly used assays—refuge-use, thigmotaxis, and foraging latency. We predicted that there would be consistent sex differences in both mean-level risk-taking behaviour and behavioural predictability across the assays. We found that risk-taking behaviour was repeatable within each assay, and that some individuals were consistently bolder than others across all three assays. There were also consistent sex differences in mean-level risk-taking behaviour, with males being bolder across all three assays compared to females. In contrast, both the magnitude and direction of sex differences in behavioural predictability were assay specific. Taken together, these results highlight that behavioural predictability may be independent from underlying mean-level behavioural traits and suggest that males and females may differentially adjust the consistency of their risk-taking behaviour in response to subtle changes in environmental conditions.</p>
Data from: The effect of environmental variation on the relationship between survival and risk-taking behaviour in a migratory songbird
<p>Temporal changes in environmental conditions may play a major role in the year-to-year variation in fitness consequences of behaviours. Identifying environmental drivers of such variation is crucial to understand the evolutionary trajectories of behaviours in natural contexts. However, our understanding of how environmental variation influences behaviours in the wild remains limited. Using data collected over 14 breeding seasons from a collared flycatcher (<em>Ficedula albicollis</em>) population, we examined the effect of environmental variation on the relationship between survival and risk-taking behaviour, a highly variable behavioural trait with great evolutionary and ecological significance. Specifically, using annual recapture probability as a proxy of survival, we evaluated the specific effect of predation pressure, food availability and mean temperature on the relationship between annual recapture probability and risk-taking behaviour (measured as flight initiation distance, FID). We found a negative trend, as the relationship between annual recapture probability and FID decreased over the study years, and changed from positive to negative. Specifically, in the early years of the study, risk-avoiding individuals exhibited a higher annual recapture probability, whereas in the later years, risk-avoiders had a lower annual recapture probability. However, we did not find evidence that any of the considered environmental factors mediated the variation in the relationship between survival and risk-taking behaviour.</p>
Data Files for the study "Exploring risk-taking behaviour as a function of cognitive flexibility and emotional intelligence"
<p><span>Risk-taking behaviour refers to how one decides to act with the possibility of negative outcomes which is often pursued in the hope of achieving a lucrative reward, and it can happen in various circumstances, which makes it important to study and understand the key factors behind this cognitive process. The present study focused on understanding these dynamics with emotional intelligence and cognitive flexibility. The present study incorporated a healthy sample (<em>n=</em>121) whose emotional intelligence was assessed with MSREIS-R, risk-taking with GDT and cognitive flexibility with WCST. The findings suggested that cognitive flexibility and sub-scale of emotional intelligence did impact risk-taking behaviour, while no moderating effect was found between them. However, the sub-scales of emotional intelligence did predict cognitive flexibility hinting at their interactive relationship which does not erase the possibility of them not affecting risk-taking behaviour completely.<span> </span></span></p> <p>Emotional intelligence questionnaire and manuals, an Excel file consisting of Emotional Intelligence Score, SPSS file, Software file (Inquisit Program file), the link to the task script and other important links, Game of dice task(raw and summary data), Wisconsin Card Sorting Test (raw and summary data).</p>

Drivers of within- and among-individual variation in risk-taking behaviour during reproduction in a long-lived bird
Plastic and selective mechanisms govern parental investment adjustments to predation threat. We investigated the relative importance of plasticity and selection in risk-taking propensity of incubating female common eiders <i>Somateria mollissima</i> facing unprecedented predation in SW Finland, Baltic Sea. Using a 12-year individual-based dataset, we examined within- and among-individual variation in flight initiation distance (FID), in relation to predation risk, nest detectability, individual traits and reproductive investment (N<sub>FID</sub> = 1009; N<sub>individual</sub> = 559). We expected females nesting in riskier environments (higher predation risk, lower nest concealment) to mitigate environmentally-imposed risk by exhibiting longer FIDs, and females investing more in current reproduction (older, in better condition or laying large clutches) to display shorter FIDs. The target of predation - adult or offspring - affected the mechanisms adapting risk-taking propensity; females plastically increased their FID under higher adult predation risk, while risk-avoiding breeders were predominant on islands with higher nest predation risk. Risk-taking females selected thicker nest cover, consistent with personality-matching habitat choice. Females plastically attenuated their antipredator response (shorter FIDs) with advancing age, and females in better body condition were more risk-taking, a result explained by selection processes. Future research should consider predator type when investigating the fitness consequences of risk-taking strategies.
