Replication Data for: Fig 17.7, BTPDs, Juvenile body mass vs litter size, 23 June 2026

This file ready for longterm storage on 26 March 2025. I considered data from the same prairie dog mother regarding litter size in different years to be independent.

Standard errors were usually small, because my sample sizes for each age were large. In some cases for this figure, I have shown SEM = 3 for Offspring body mass or SEM = 30 for Cumulative body mass of all offspring--because showing slightly inflated SEMs is better than suggesting no variation at all, in my opinion. Litter size = litter size at first emergence of offspring from their natal nursery-burrow = number of weanlings.
