Costs of social conflict: do injuries mirror patterns of aggression in blue monkeys?

In wild animals, injuries often arise from intraspecific contests, and therefore may reveal challenges and selection pressures related to social conflict. We evaluated whether known aggressive patterns predicted injury patterns in wild blue monkeys, in which most injuries of known cause resulted from conspecifics. After describing injuries and their causes in 12 groups monitored over 13 years, we compared injury distributions across age-sex class and season. Adult males were much more likely, adult females about equally likely, and immatures much less likely to sustain injuries relative to random expectation. Among adult males, injuries were most common in the mating season. Using multivariate models, we examined how individual, social, and demographic factors predicted injury rates in adult females and immatures. Rates were higher for adult females versus all immatures, for individuals in smaller groups, and for those living in groups frequently exposed to novel adult males and with fe..., Data were collected from November 2006 through December 2019 via field observations of wild, individually-recognized blue monkeys (Cercopithecus mitis stuhlmanni) living in multiple groups in the Kakamega Forest, Kenya. The study groups were part of a long-term project that began in 1979. During the 2006-2019 period, each group was monitored on a near daily basis by members of an experienced field team that noted any injuries during a census of group members carried out on each observation day. Each injury was assigned to the date on which it was first noted.

Give a brief summary of dataset contents, contextualized in experimental procedures and results.

## Description of the data and file structure

There are two data sets associated with the published paper, which provides further information about each of them. Dataset1 was used to create Dataset2. In both data sets, blank cells represent missing data.

***

**Dataset1 (Cords-Arguelles\_Dataset1.csv)** is a catalog of all unique injuries observed during the study period, one per row. For each injury, the data set includes information on the following variables, listed from left to right.
 

1. ***date***: the date when the injury was first observed by the field team (YYYY-MM-DD).
2. ***group***: the identity of the group in which the injured animal lived on the date when the injury was first observed.  
3. *...
