Abstract
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 patrolling but were less effective at excluding intruder males as compared to males with small territories. Intruding males failed to establish territories and displayed an alternative tactic featuring greater exploration as compared to genetically identical territorial males. Alternative tactics did not lead to equal reproductive success—males that acquired territories experienced greater survival and had greater access to females.

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.
Figure_1_data.csv:
period: a categorical variable of whether the measured transitions occured before the invasion, the night of the invasion, or after the invasion of new males.
period_plot: a numerical variable used only to produce jitter to improve visualization via the attached R script.
Name: the name of the animal being measured
transitions: the mean number of transitions that the animal made during the given period
sd: the standard deviation of the number of transitions that the animal made during the given period
n: the number of nights included in the given period
se: the standrd error of the number of transitions that the animal made during the given period
Figure_3A_data.csv
Name: the name of the animal being measured
Night: the night of the experiment during which the number of zones visited was measured
Zones: the number of zones visited by the animal on the given night
max_night: the latest night during which the animal being measured was still alive in the enclosure
days_in: how long the animal had been present in the enclosure during the given night
period: a categorical variable indicating the period of the experiment during which the given night fell
Figure_3B_data.csv
Name: the name of the animal being measured
Antenna: the antenna in which an animal's presence was being assessed
Night: the night of the experiment during which the number of zones visited was measured
Reads: the number of RFID reads that the animal generated at the given antenna on the given night
visited: binary. (1) if the number of reads is greater than 0. Otherwise (0).
terr: the status of the territory holder of the resource bin monitored by the given antenna. "one" means that the territory holder controlled a single zone. "two" means that the territory holder controlled two zones.
holder: the identity of the territory holder at the given antenna.
Figure_4_data.csv
Name: the name of the animal being measured
Night: the night of the experiment during which the cumulative number of zones visited was measured
csum: the cumulative number of total unique zones that the animal had visited by the conclusion of the given night
Treatment: a categorical variable of when the animal was added to the enclosure. Either on night 1 ("early") or night 6 ("late").
nights_in: how long the animal had been present in the enclosure during the given night
new: the number of new zones visited by the animal on the given night (i.e. that the animal had never visited before).
Figure_5_data.csv
name: the name of the animal being measured
sex: the sex of the animal being measured
start: the start of the survival period being measured
end: the end of the survival period being measured
death: a binary indicator of whether the survival period being measured ended in death (1 if yes, 0 if no).
Territory: a categorical measure of whether the animal was either a female ("F"), was a territory-holding male (1) or a territory-less male (0).
FigureS1_data.csv
Name: the name of the animal being measured
Night: the night of the experiment during which monopolization was being measured
Antenna: the antenna in which an animal's presence was being assessed
Treatment: a categorical variable of when the animal was added to the enclosure. Either on night 1 ("early") or night 6 ("late").
Reads: the number of RFID reads from the given animal at the given atenna on the given night
Total_Reads: the total number of male RFID reads at the given antenna on the given night
prop_reads: the proportion of male RFID reads at the antenna that was generated by the given male on the given night
type:a categorical indicator of whether the antenna was contained within the territory containing the given antenna (Single = 1 zone territory, Double = 2 zone territory)
transitions_data_for_stats.csv
Name: the name of the animal being measured
noon_to_noon_day: the night during which the animal was measured
period: a categorical variable of whether the measured transitions occured before the invasion, the night of the invasion, or after the invasion of new males.
transitions: the number of transitions between zones performed by the animal on the given night
