Relplication data for Fig 14.17, BTPDs, Sex dim of juveniles in autumn, 11 May 2026

In October of each year, this year's "juveniles" had emerged from their natal nursery-burrows about 4-5 months earlier. I created this file from SYSTAT file = ALLFEMWT.SYS, which was created on 19 Nov 1991, which I assumed that I checked TWO TIMES at its creation Male BTPD data come from EXCEL file = BTPDS, all male wts, 28 July 2020, which I assumed that I checked TWO TIMES at its creation Some new data were added on 16 Jan 1992 and on 09 Feb 2012 BTPD female additions in 1992 or 2012: H in 1978, H2 in 1981; RR7 in 1982, 67 in 1983, CR in 1985, WARS in 1986, 60 in 1986 I assume that these files were checked TWO TIMES for my first book (Hoogland 1995).

But notice the changes above.

Note

For Autumn weights, I do NOT use BTPD weights from August or September. All weights are from October through early December. So, for example, I have deleted MANY BTPD weights from August and September 1980.

I have used this file to compare body masses of 5-month old male and female BTPDs in October-December

Note

This file does NOT include data from August or September For sexual dimorphism of older prairie dogs, see Figures 14.15 and 14.6. For every prairie dog juvenile that I captured and marked as a juvenile, I score age = 0 at first emergence from the natal burrow-entrance, and 0.5 = 1 in its first October; 1 in the first mating season and at first juvenile emergences ; 1.5 = 2 in the second October; and >=2 for all later mating seasons and all later first juvenile emergences Remember: To analyze September-October body masses of this year's yearlings, SELECT AGE = 1.

Remember: Yearling during first mating season was a juvenile (5 months old) in October Sample sizes are above the SEM lines above bars in Fig 14.17. Year = 78 = 1978, 79 = 1979, 80 - 1980, etc. Summary of ages: Age = 0 years at juvenile's first emergence; Age = 0.5 years = 1 year at that juvenile's first October: Age = 1 year for that juvenile's first mating season in February or March; Age = 1 year at that juvenile is a yearling for the first juvenile emergences of other juveniles of other females in the next year.

All body masses in GRAMS For Fig 14.17 for BTPDs, the comparison is for body mass of male juveniles in October (N = 189) vs body mass of female juveniles in October (N = 178). Other body masses of juveniles not shown in Fig 14.17 are also in this EXCEL file. No data for UPDs, because I never captured UPDs in September or October Sample sizes are above the standard errors (SEM lines) above bars in Fig 14.17.
