Data from: Determinants of hyena participation in risky collective action

# Determinants of hyena participation in risky collective action Data and code associated with Proc B manuscript *Determinants of hyena participation in risky collective action. doi: 10.1098/rspb.2023.1390* Here we study cooperative mobbing behavior by spotted hyenas during fights with lions. We use long-term observational data from the Mara Hyena Project to identify factors that predict: (1) when hyena groups engage in cooperative fights with lions, (2) which individuals choose to participate, and (3) how the benefits of victory are distributed among cooperators and non-cooperators. Dryad doi: [https://doi.org/10.5061/dryad.1rn8pk10w](https://doi.org/10.5061/dryad.1rn8pk10w) ## Description of the data and file structure All data and code are numbered for ease of use, and users should sort by file name to achieve the correct ordering. Raw data are loaded into R and preliminarily cleaned in R script 01. Data are then reshaped in R scripts 03-07, and output is saved in Rdata files 04-08. Models in R script 09 address question (1) when hyena groups engage in cooperative fights with lions. Data are again reshaped in R script 11, and output is saved in Rdata file 12. Models in R scripts 13-16 address question (2) which individuals choose to participate in cooperative fights with lions. Data are again reshaped in R scripts 21 and 24, and output is saved in Rdata files 22 and 25. Models in R scripts 23 and 26 address question (3) how the benefits of victory are distributed among cooperators and non-cooperators. ## Sharing/Access information Data and code can also be found at GitHub: https://github.com/tracymont/hyena\_mobbing/ ## Code/Software All coding was done in R.
