Replication data for: Fig 11.1, Top left, BTPDs, Colony sizes and compositions by year, 18 Dec 2025

USUALLY, male and female BTPDs do not copulate as yearlings-- hence the lumping of BTPD male and female yearlings so graph is not too cluttered Note also that these numbers are for MAY of each year Note also: I have EXCLUDED data from 1975 (my first year at Rankin Ridge), but I have INCLUDED data from 1989 (when Jim Loughry worked at Rankin Ridge). This file checked TWO TIMES by JLH alone on 25 March 2020 All data for this file from Table 16.1 of Hoogland 195 (page 377).

Note

Counts of emergent juveniles in this EXCEL file INCLUDE babies never captured but listed in Table 16.1 of Hoogland 1995 Weanling = juvenile at first emergence from the natal burrow entrance Colony size = number of adults and yearlings in May For this EXCEL file, adult = prairie dog that was >=2 years old For this EXCEL file, yearlings were young adults that emerged from the natal nursery-burrow >9 months ago, but <20 months ago.

These data used for Fig 11.1 in Hoogland 2026. This file ready for longterm storage on 15 Feb 2025. File name = Fig 11.1, Top left, BTPDs, Colony sizes and compositions by year, 18 Dec 2025 All data from BTPD Rankin Ridge Colony at Wind Cave National Park.
