Replication data for Fig 4.1, Gunnison uterine litter size vs litter size at first juvenile emergence, 19 Sept 2025.

For each gunnison female shown here, I used one data point, which was the difference between uterine litter size in late pregnancy vs litter size at first juvenile emergence from the natal nursery-burrow. For this figure, 0 = no difference; 1 = difference of 1 juvenile; and so forth. Numbers for each uterine litter size can be calculated directly from the top histogram of this Fig 4.1 of Hoogland 2026.

Sample sizes for GPD uterine litter sizes in top graph differ from (smaller) GPD litter sizes in bottom graph because many females in late pregnancy did not eventually wean a litter. This file ready for longterm storage on 24 January 2025.
