The bulk of analysis was conducted on the dataset labelled, "AnalyzedDataset". Survival rates used to calculate age-specific residual reproductive value were derived from the dataset labelled, "CondensedMarkDataset". These are both derived from Fred Janzen's long-term dataset on the nesting ecology of painted turtles along the Mississippi River. See the paper for full methods.
List of Column names:
Date = Date of observation
Year = Year of observation
Nest = Within-year number assigned to a nest
Sex = Sex of the individual of the observation
PL = Plastron length (mm)
SoilType = Type of soil the nest was constructed in
TrueID = Unique ID number assigned to an individual
YearDayLaid = Unique nest number across all years
Age = Age of female
ClutchSize = number of eggs laid
ClutchMass = mass of clutch
DTW = Distance to water of nest
The rest of the variables are calculated metrics and/or transformed variables that can be read with the following labelling guide:
1. RRV prefix denotes that the trait is the calculated residual reproductive value for the trait name that follows.
2. BC denotes that the variable is Box-Cox transformed.
3. 2 at the end denotes that variable was squared to assess quadratic variation.
4. C at the end denotes that variable was standardized to a mean of 0 and unit variance.
