Genetically identical mice express alternative reproductive tactics depending on social conditions in the field

In many species, establishing and maintaining a territory is critical to survival and reproduction, and an animal’s ability to do so is strongly influenced by the presence and density of competitors. Here we manipulate social conditions to study the alternative reproductive tactics displayed by genetically identical, age-matched laboratory mice competing for territories under ecologically realistic social environmental conditions. We introduced adult males and females of the laboratory mouse strain (C57BL/6J) into a large, outdoor field enclosure containing defendable resource zones under one of two social conditions. We first created a low-density social environment, such that the number of available territories exceeded the number of males. After males established stable territories, we introduced a pulse of intruder males and observed the resulting defensive and invasive tactics employed. In response to this change in social environment, males with large territories invested more in ..., , , \"Genetically Identical Mice Express Alternative Reproductive Tactics Depending on Social Conditions in the Field\"

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

This data and code allow for the reproduction of analyses and figures contained in the manuscript. It contains data derived from our RFID system in September 2021 during this experiment.

## Description of the data and file structure

The R script relies in turn on each of the data files contained in this folder. Each data file is labeled to identify the figure that it supports.

Note that Figure 2 and its statistics also derive from the data first uploaded to produce Figure S1.

Below are brief column descriptions for each column in each data file.
