Keywords: UPDs, Females, Age vs litter size and yearlings, Reproductive senescence File name = Fig 12.1, Lower left, UPDs, Females, Age vs juveniles, yearlings, 23 March 2026 I created this file (with more variables) on 09 Feb 1996. I assume that I checked it TWO TIMES at creation. No eartag information in this file. Litter size = litter size at first juvenile emergence = number of weanlings Yearling = number of juveniles from litter that survive for >=9 months after first emergence Female age = number of years since first emergence from natal nursery-burrow Female body mass of mother before, during, or just after mating season. I ASSUME that date of weaning = date of first juvenile emergence from the natal burrow entrance, but I know this is not completely true--because nursing of juveniles continued to occur after first juvenile emergences Date = 30 May 2020. I use this file to compare UPD female age vs (a) litter size and (b) number of yearlings When littsize = 99, data were missing or mixing of litters occurred so that I could not get an accurate estimate of litter size at weaning. When litter size = 99, then I could not get an accurate estimate the number of the number of yearlings either. So, I delete cases of Female age, Littsize, and Yearlings when littsize = 0 Note that yearlings = 0 in a few cases of Littsize = 99. Why is that? I ignore all cases for Female age, female body mass, litter size, and yearlings when Littsize = 99 I verified these numbers and made a few corrections on 03 May 2025 Female body masses are in grams File name = Fig 12.1, Lower left, UPDs, Females, Age vs juveniles, yearlings, 23 March 2026
