Replication data for Fig 14.7, WTPDs, Male body mass vs probability of copulation, 05 May 2026

This file ready for longterm storage on 07 March 2025. Age = age in years since first emergence from natal nursery-burrow For BTPD males and females, I could compare body mass during the mating season with probability of copulation. For UPDs and WTPDs, I also could compare body mass during the mating season with (a) probability of weaning a litter for females and (b) evidence of copulation (observed copulation, or PSDT) for males For GPDs, UPDs, and WTPDs, I assume that EVERY FEMALE copulated every year.

I observed very few exceptions to this axiom. Indeed, I am certain of <1-2 exceptions for each of these three species. These data used for Figure 14.7 in Hoogland 2026.

This file ready for longterm storage on 07 March 2025. Wt = weight = body mass Age = age in years since first emergence from natal nursery-burrow I considered data from the same male in different years to be independent. Body mass during mating season = body mass just before, during, or just after mating season.

I defined mating season as the time interval between (and including) the first and the last copulation at the study colony. Body mass at first juvenile emergences = body mass just before, during, or just after the time period when juveniles were first emerging from their natal nursery-burrows. Almost all WTPD males at >=2 years copulated.

Yearling WTPD males sometimes DID copulate, but often did NOT copulate. See Chapter 11 of Hoogland 2026. All body masses are in GRAMS.
