Replication Data for: Fig 25.5 (Bottom), WTPDs, Female lifetime fitness vs the number of interspecific killings (IKS) over lifetime, 31 July 2026

Some white-tails also killed ground squirrels across two or more years (see text and Fig 25.5b). Overall, we observed IKs by 48 different marked white-tails (one data point per lifetime for 11 males and 37 females). The number above each SE line indicates the number of females for which I have information on lifetime number of interspecific killings (IKs) and lifetime fitness = lifetime number of yearlings These data checked TWO TIMES for writing of Hoogland and Brown 2016: Prairie dogs increase fitness by killing interspecific competitors.

Proceedings Royal Society B 283:20160144. These data checked again on 31 July 2026 These data used for Fig 25.5 (Bottom) in Hoogland 2026. This file ready for longterm storage on 28 April 2025. 73#2 (H19) was a small immigrant in September 2010.

I assume she was a juvenile at first capture, and a yearling in 2011. White-tail female-66 (J41) killed one WGS in 2012, but I could not estimate her annual or lifetime fitness because 2012 was my last year of research at my single study-colony at the Arapaho National Wildlife Refuge near Walden, Colorado. Female-66 did not wean offspring as a yearling in 2012.

So, the addition of WTPD female-66 to the file did NOT affect the statistics in Hoogland and Brown 2016 for either Annual fitness or Lifetime fitness. ARS wean and ARSyrl were both 0 for WTPD female-66 in 2012, ARS wean and ARSyrl were both 0 for WTPD female-66 in 2012, but I have no information on the survivorship of WTPD female-66 (J41) until 2013. These data checked TWO TIMES for writing of Hoogland and Brown 2016: Prairie dogs increase fitness by killing interspecific competitors.

Proceedings Royal Society B 283:20160144. I checked a third time on 31 July 2026. These data used for Fig 25.5 (Bottom) in Hoogland 2026.

This file ready for longterm storage on 28 April 2025. WTPD female = Nyanzol marker Victims = number of IK victims for each WTPD killer or nonskilled

Note

All data in this EXCEL file and Fig 25.5 are from WTPD FEMALES ONLY. See Chapter 25 of Hoogland 2026 for IKs by WTPD males. LRS wean = number of weanlings produced over a female's lifetime LRS = Lifetime Reproductive Success LRSyrl = number of yearlings produced by female over her lifetime Yearling = weanling that survived for >=9 months after weaning All data in this EXCEL file and Fig 25.5 are from single WTPD study-colony at Arapaho National Wildlife Refuge near Walden, Colorado Female lifetime fitness is defined above.

File name Fig 25.5 (Bottom), WTPDs, Female lifetime fitness vs the number of interspecific killings (IKS) over lifetime, 31 July 2026 Additional notes about this file, useful probably only to John Hoogland On 07 Jan 2015, lifetime victims for 4SRS (947) changed from 1 to 2--because 4SRS killed 1 WGSX baby in 2009, when she did NOT wean a litter. On 20 November 2015, C6, H03 changed from "missing data" to 0, because NONE of C6 babies alive for final census in July 2012 On 23 Nov 2015, victims for WA4 (9163) changed from 0 to 1--because WA4 killed 1 WGSX baby in 2007, when she did NOT wean a litter.

On 25 Nov 2015, I changed Reliable 1 for 76 (eartag H8) from 1 to 0. 73#2 (H19) was a small immigrant in September 2010. I assume she was a juvenile at first capture, and a yearling in 2011. For RSRAB (850), I change the lifetime number of victims from 8 to 9.

On 19 Feb 2016, I HAVE incorporated this change into our analysis by sending Charles Brown corrected file on 19 Feb 2016. Note on 22 Feb 2016. This the FINAL FILE that we use for Hoogland and Brown for Proceedings of the Royal Society.

This file includes data ONLY FROM FEMALES FOR WHICH WE KNOW EXACT AGES AND EXACT LONGEVITY. So, no entries in this file for original residents, or females that were still alive at the end of our research in July 2012. Reason: Original residents might have reproduced before we arrived in 2006, and females still alive in July 2012 might have reproduced in years after our departure.

Note on 22 February 2016: The change for RSRAB for lifetime fitness HAS BEEN incorporated into this file and into the final analysis for Brown and Hoogland Proceedings of the Royal Society.

Note

On 18 Aug 2022, I added 1 victim for fem-66 (J41) for 2012. I discovered the omission for fem-66 (J41) on 18 Aug 2022. WTPD female-66 (J41) was NOT in the stats generated by Charles Brown for ARS and LRS for Hoogland and Brown 2016.

Except for the actual stats generated by Brown, I have incorporated this new information for WTPD Female-66 (J41) into my book whenever I can. Total number of observed IKs is now 102, for example. Note, however, that WTPD female-66 was a yearling in 2012, and 2012 was our last year of WTPD research.

Consequently, I have no estimates of Annual fitness or Lifetime fitness for WTPD Female-66 (J41) Note about BSBB in 2012 (J71, born in 2011). BSBB weaned a litter of 5 in 2012, but was captured soon thereafter by a badger. BSBB is NOT in this EXCEL file or Fig 25.5 (Top).

Should BSBB BSBB (J71) be included? It seems that BSBB should be included. Hoogland and Brown (2016) did NOT include BSBB (J71) in analysis of Annual fitness, so I will not include here either.

But Hoogland and Brown DID include BSBB (J71) in analysis of Lifetime fitness. This seems inconsistent. Inclusion of BSBB (J71) in analysis of Annual fitness would still lead to P < 0.001.

But repeat: This EXCEL file and Fig 25.5 (Top) do NOT include WTPD female BSBB (J71)
