Replication Data for: Fig 25.5 (Top), WTPDs, Female annual fitness vs the number of interspecific killings (IKS) per year, 31 July 2026

Some WTPDs 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 IKs per year vs WTPD female annual fitness.

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 (Top) in Hoogland 2026.

This file ready for longterm storage on 28 April 2025. File name Fig 25.5 (Top), WTPDs, Female annual fitness vs the number of interspecific killings (IKS) per year (31 July 2026) 73#2 (H19) was a small immigrant in September 2010. I assume she was a juvenile at first capture, and a yearling in 2011.

Where are data for WTPD female-66 (J41) in 2012?--This info added on 19 Aug 2022, but was NOT known for Hoogland and Brown 2016 White-tail female-66 (J41) killed one WGS in 2012, but I could not estimate her annual fitness because 2012 was my last year of research at my WTPD colony. Female-66 did not wean offspring in 2012. So, the addition of WTPD female-66 to the file did NOT affect the statistics in Hoogland and Brown 2016.

ARS wean and ARSyrl were both 0 for WTPD female-66 in 2012, but I do not know if she survived until 2013. These data used for Fig 25.5 (Top) in Hoogland 2026. This file ready for longterm storage on 28 April 2025.

WTPD female = Nyanzol marker Victims = number of IK victims for each female WTPD killer or nonkiller Body mass in May = female body mass just before, during, or just after WTPD weanlings were first emerging from their natal nursery-burrows Female age = female age in years since she first emerged from natal nursery-burrow Clan size = number of adult and yearling WTPDs in WTPD female's home territory in May (includes the female herself) Ward size = number of adult and yearling WTPDs living in female's home ward

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. ARS wean = litter size at weaning = number of weanlings.

ARS wean ranged from 0 to 8, ARS = Annual Reproductive Success ARSyrl = number of yearlings produced by female Yearling = weanling that survived for >=9 months after weaning Femsurv = 0 means that female did NOT survive until next mating season Femsurv = 1 means that female DID survive until next mating season 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 fitness is defined above.

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) File name Fig 25.5 (Top), WTPDs, Female annual fitness vs the number of interspecific killings (IKS) per year, 31 July 2026
