For GPDs, the most common litter size at first juvenile emergence was 4 (Fig 17.5). N = 171 GPD litters of size 4. P-value is from the chi-square goodness-of-fit test. Expected values assume a juvenile sex ratio of 1:1 at first emergence (50% males, 50% females). Litter size = litter size at first emergence of offspring from their natal nursery-burrow = number of weanlings. These data used for Fig 24.2 in Hoogland 2026. This file ready for longterm storage on 25 April 2025. I considered litter sizes from the same prairie dog mother in different years to be independent. The expected number of males per litter assumes a balanced overall sex ratio (50% males, 50% females). These numbers checked TWO TIMES on 09 May 2022, again on 30 July 2026 File name: Fig 24.2, GPDs, Observed vs Expected numbers of litters for each number of male and female weanlings when litter size = 4, 30 July 2026.
