Data and code for: Partitioning variance in a signaling trade-off under sexual selection reveals among-individual covariance in trait allocation

# Data and code for:Partitioning variance in a signaling trade-off under sexual selection reveals among-individual covariance in trait allocation Michael S. Reichert, Ivan de la Hera, Maria Moiron Evolution 2024 Summary: Data are measurements of the characteristics of individual calls from a study of individual variation in calling in Cope's gray treefrog, *Hyla chrysoscelis*. ## Description of the Data and file structure Note: There are some NA entries in the data files because these are outputs of R data frames. NA corresponds to an empty cell (i.e. no data are available for that variable for that row). List of files: TreefrogVariance.csv -This is the main raw data file. Each row contains the data from a single call. Variables are as follows: CD - call duration, in seconds CR - call rate, in calls/second *Note that the intercall interval (ICI), which is analyzed in the supplement as an alternative to call rate, is not directly included in this data file but can be calculated as: ICI = (1/call rate) - call duration DC - call effort, unitless (product of call duration and call rate). Note that DC is used here because traditionally in the frog literature this is referred to as "duty cycle", but we use call effort in the paper as the more intuitive term for the non-frog specialist. ID - The unique ID code of the frog Expt - The "social context". One of four different situations in which the frog was recorded. B1 - spontaneous calling prior to playback, "baseline". P1 - calling in response to an "average" advertisement call playback. P2 - calling in response to a "competitive" advertisement call playback. B2 - spontaneous calling after playback "post-playback baseline" Date - The date in M/D/Y format CalendarDay - The day number of the year, with 1 January being day 1 Temperature - Body temeperature of the frog in degrees Celsius. HoursPast9 - Referred to in text as "Time of night", this gives the start time of the recording, in hours after 9 PM Year - Either 2019 or 2020 RepeatabilityResults.csv -For convenience, the results of the repeatability analyses used to make Figure 1. Variables are as follows: Character: The call characteristic. CD = call duration, CR = call rate, DC = duty cycle Context: The social context in which the repeatability coefficient was calculated. Cross-context refers to a calculation from combined data across all four contexts. RepeatabilityCoefficient: The value of the repeatability coefficient estimated from the model LowerCI: The lower bound of the 95% credible interval for the repeatability coefficient UpperCI: The upper bound of the 95% credible interval for the repeatability coefficient. \################### All analyses were performed in R version 4.1.0 software The following packages were used: MCMCglmm version 2.33 tidyverse version 1.3.1 cowplot version 1.1.1 RColorBrewer version 1.1-2 ## Sharing/access Information Available on Dryad# 配套数据与代码：《性选择下信号权衡的方差分解揭示性状分配的个体间协方差》（Partitioning variance in a signaling trade-off under sexual selection reveals among-individual covariance in trait allocation） 作者：Michael S.
