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

description: 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.

 Depending on Social Conditions in the Field" by MN Zipple, CC Vogt,
 and MJ Sheehan ------------------------------------- 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
