Data Overview

This Dryad repository contains the primary data files (four .csv files) required to interpret the results of the associated publication. These files contain summary metrics for individual female deer, longitudinal survival data, and calf survival data.

Code and Reproducibility: The Quarto source code (red_deer_analysis.qmd) containing the full analysis workflow and the auxiliary network data file (MRQAP_data.RData) are not included in this Dryad package. They are archived separately at Zenodo to facilitate reproducibility.

Note on Scaling: Files with "scaled" in the filename contain data that have been centered and scaled (Z-scores) to facilitate statistical modeling.

File Descriptions

1. life_time_data.csv AND scaled_life_time_data.csv

Description: Summary metrics for individual female deer calculated over their entire lifespan. Row definition: One row per individual female.

• X: Row index (numerical identifier/artifact of data export).
• id: Unique identifier for the individual female deer (alphanumeric string).
• lifespan: Total years lived (unit: years).
• sum_degree: The sum of the individual's annual degree centrality scores over its lifetime (count).
• sum_strength: The sum of the individual's annual social strength scores (sum of weighted ties).
• sum_eigen: The sum of the individual's annual eigenvector centrality scores (unitless index).
• mean_mat: Average matrilineal rank or status during the individual's life (numeric rank).
• mean_matSize: Average size of the individual's matriline over its life (unit: count of individuals).
• mean_HRO: Mean Home Range Overlap index (unitless index, 0-1).
• mean_N: Mean spatial coordinate - Northings (unit: meters, UK Ordnance Survey grid).
• mean_E: Mean spatial coordinate - Eastings (unit: meters, UK Ordnance Survey grid).
• matriline: The specific matrilineal group name/ID the individual belonged to (categorical).
• LRS: Lifetime Reproductive Success - Total number of calves produced that survived to 1 year (unit: count of calves).
• LBS: Lifetime Breeding Success - Total number of calves born (unit: count of calves).
• mean.grp.size: Average size of the social groups the individual was observed in (unit: count of individuals).
• matSize: Final or average size of the matriline (unit: count of individuals).

2. scaled_annual.csv

Description: Longitudinal data used for survival analysis. Row definition: One row per individual per year (person-year format).

• X: Row index (numerical identifier/artifact of data export).
• id: Unique identifier for the individual (alphanumeric string).
• year: The calendar year of observation (unit: year).
• degree: Number of social associates in that year (count).
• strength: Sum of the weights of social ties in that year (sum of weights).
• eigen: Eigenvector centrality in that year (unitless index).
• mat: Matriline identifier code (categorical).
• end: End time of the interval for survival modeling (unit: age in years).
• start: Start time of the interval for survival modeling (unit: age in years).
• death: Binary indicator of mortality (1 = died in this interval, 0 = survived).
• DeathYear: Calendar year of death (unit: year).
• BirthYear: Calendar year of birth (unit: year).
• lastSeen: The last calendar year the individual was observed alive (unit: year).
• matSize: Number of individuals in the matriline in that year (count).
• HRO2: Home Range Overlap metric for that year (unitless index).
• LifetimeE: The overall lifetime average spatial coordinate - Eastings (unit: meters).
• LifetimeN: The overall lifetime average spatial coordinate - Northings (unit: meters).
• centroid: Spatial centroid of the individual's sightings (coordinate pair).
• sex: Biological sex (all "F" for females).
• matriline: Name or ID of the matrilineal group (categorical).

3. scaled_calves_survival.csv

Description: Data linking maternal social traits to the survival of specific offspring. Row definition: One row per calf.

• X: Row index (numerical identifier/artifact of data export).
• ego: Unique identifier for the calf (alphanumeric string).
• ego.birth: Calendar year the calf was born (unit: year).
• ego.mom: Unique identifier for the calf's mother (alphanumeric string).
• ego.survived.frist.year: Binary survival indicator (1 = calf survived to 1 year of age, 0 = died).
• mom.degree: The mother's degree centrality in the year of the calf's birth (count).
• mom.strength: The mother's social strength in the year of the calf's birth (sum of weights).
• mom.eigen: The mother's eigenvector centrality in the year of the calf's birth (unitless index).
• mom.obs: Number of times the mother was observed/sampled in that year (count).
• matSize: Size of the matriline in the year of birth (count).
• id: Maternal ID, matches ego.mom (alphanumeric string).
• HRO2: Maternal Home Range Overlap index (unitless index).
• LifetimeE: Maternal spatial metric - Eastings (unit: meters).
• LifetimeN: Maternal spatial metric - Northings (unit: meters).
• centroid: Maternal spatial centroid.
• year: The calendar year associated with the maternal traits/calf birth (unit: year).
• matriline: Name or ID of the matrilineal group (categorical).
