Replication Data for: Fig 2.3, BGUW, Dispersal vs age, 29 July 2026

New data added on 08 July 2019. These data are from RMC and VCC of VCNP. These data now checked TWO TIMES--once by JLH alone, once with Judy On 09 July 2019, I notice that three lines of UPD data (species = 3) were listed as GPD data (species = 2).

The lines were 1377, 1378, and 1470. I change all three cases to species = 3. This will affect the UPD and the GPD stats.

Note that the GPD stats now include data from VCNP's RMC and VCNP's VCC. As noted above, the numbers in Column-D (from an old SYSTAT FILE) are of little use On 21 April 2025, I add information from GPD female-H4 (Q61), who was born in 2015 and dispersed as yearling in 2015. H4 moved herself and her babies across the street immediately after I live-trapped all the babies.

I score this as natal dispersal. OLDFile name = BGUW, All Dispersal, 07 June 2021 The SYSTAT output from this EXCEL file is IDENTICAL to output form 10 July 2019. Note immediately above says that I checked everything on 09 July 2019.

But note: New variables in this file include Nctlife and Age of dispersal Data for these last two variables come from File = BGUW, Dispersal vs age, 04 June 2021 See note immediately below for File name = BGUW, Dispersal vs age, 04 June 2021 I pasted data from File name = BGUW, Dispersal vs age, 04 June 2021 into THIS EXCEL file Notice that my pasting allows me to verify that data for variables = Mother, Sisters, Bros from File name = BGUW, Dispersal vs age, 04 June 2021 allows me to verify that data are on same lines for file = ALL Dispersal, 07 June 2021.

If these variables all match up, then I will assume that data for Nctlife and Age of dispersal are also in the right places Note well, however: I added data to this EXCEL file from older file. So, perfect match up will not possible for those cases when I added new data Note, for example, that the older file did not have GPD data from RMC or VCC colonies. In SYSTAT, I will create variable = DISPEVER = Dispersal ever = 1 - nctlife.

Dispever = 0 means that the prairie dog never dispersed Dispever = 1 means that the prairie DID disperse at some time in its life, at any age So, I will use variable = Dispever to make histogram of whether prairie of either sex ever dispersed vs species And I will use variable = Nctlife to make histogram of prairie dogs of either sex remained in NCT or life Nctlife = 0 means that prairie dog did NOT remain in NCT for life Nctlife = 1 means that prairie dog DID remain in NCT for life--i.e., no dispersal Note well: No data for LAST YEAR of research at every study-colony, because obviously we could not track dispersal in the year after the last year for any study colony Last year for BTPDs with JLH at WCNP was 1988 (I did not use BTPD data from Loughry only in 1989); last year for GPDs at PEFO was 1995; last year for UPDs at BCNP was 2005; last year for WTPDs at ANWR was 2012 (I do not use WTPD data from my Ph.D. research of 1974-1976); last year for GPDs at RMC was 2016; and last year for GPDs at VCC was 2018 OLDFile name = BGUW, Dispersal vs age, 04 June 2021 I created this file from SYSTAT file = Disperse.sys, which I created on 13 Oct 2011 Note in hard copy says that I checked this file through case 1844 THREE TIMES.

But this file has 1845 cases. Where the difference of 1? I corrected this problem for case-1845 on 18 April 2025.

See above note for H4 (Q61). Note on 08 June 2021. How did I compute variable = Nctlife?

It is NOT an accurate indicator of whether a prairie dog remained in its natal territory for life. Note on 03 July 2021. Today I make corrections for a few WTPD entries.

This file should now be 100% correct. I have checked data for all four species TWO TIMES. See the many notes above.

OLDFile name is now BGUW, ALLdispersal, 05 July 2021 See SYSTAT output to show that numbers and stats for BGUW, ALLdispersal, 05 July 2021 are IDENTICAL to numbers and stats for file = BGUW, Dispersal vs kin, Final ages, 05 July 2021-- but I made a few changes on 05 and 06 July 2021 to BGUW, Alldispersal, 06 July 2021--so this might not be true anymore On 06 July 2021, I verify that I have entered dispersal data FOR EVERY GPD in our GPD litter summaries for RMC and VCC.

I need to add a few GPDs that I had missed when I created the file. Remember: No data from 2016, because that was my last year at RMC. And no data from 2018, because that was my last year at VCC.

I used this EXCEL file for Fig 22.3 to create EXCEL file for Fig 22.2. To do that, I added the numbers = sample sizes for each sex and species in THIS EXCEL file, and then used sample sizes in Fig 22.2 to create percentages. All this is a little confusing--but I have checked the EXCEL file and data TWO TIMES for Figs 22.2 AND 22.3.

On 09 July 2021, I check WTPD data for Mother, Sisters, and Bros, and I make ONE CHANGE Born in 2010, 3SBS (F55) had one brother (male-33) File name = Fig 22.3, BGUW, Dispersal vs age, 29 July 2026
