Replication data for Figs 15.16 and 15.17, GPDs, Females, Date of estrus vs dates of parturition and weaning, 21 May 2026

No Nyanzol markers or eartags in this file. One data point per female per year. I considered data from the same female in different years to be independent.

Note well: All these data are from Petrified Forest National Park (PEFO) for 1989 through 1995 --No data from RMC (Redondo Meadow Colony) or VCC (Visitor Center Colony) of Valles Caldera National Preserve Dates shown here are Julian dates. Julian date of copulation = 71 = 12 March, for example. Julian date of first emergence of juveniles from natal burrow entrance = 145 = 25 May, for example.

Julian date of parturition = 84 = March 25, for example. These Julian data are for NON-LEAP years. Julian dates for leap years after 28 February differ by 1 day.

No Nyanzol markers or eartags in this file. One data point per female per year. Fig 15.16 shows female's date of estrus vs date when female's offspring first emerged from natal nursery-burrow.

Fig 15.17 shows female's date of estrus vs date female's date of parturition (giving birth). See Chapter 15 of Hoogland 2026 for discussions of estrus, underground consortships, CUCs, and CACs. This file ready for longterm storage on 19 March 2025.

See Chapter 15 of Hoogland 2026 for discussions of estrus, underground consortships, CUCs, and CACs. Because of spontaneous abortions, infanticides, and predations, sample sizes for dates of parturition and litter size at first emergence of juveniles were always smaller than dates of estrus across all females of all four species.
