Replication data for Fig 14.15, Bottom, BGUW, Adults, Sexual dimorphism at first juvenile emergences, 09 May 2026

For both males and females, BTPD data are from >=2 year old adults only-- because BTPDs usually did NOT copulate as yearlings. For males and females of GPDs, UPDs, and WTPDs, body masses are from both 1-year olds (yearlings) and >=2 year olds, because yearling females of these species almost always copulate, and yearling males of these species often DO copulate These data used for Figure 14.15, Bottom, in Hoogland 2026.

This file ready for longterm storage on 12 March 2025. First juvenile emergences usually occurred in late May or early June for all four species. BGUW indicates black-tailed, Gunnison's, Utah, and white-tailed prairie dogs GPD body masses are from all three study-colonies: Petrified Forest National Park (PEFO), Redondo Meadow Colony (RMC) at Valles Caldera National Preserve (VCNP), and Visitor Center Colony (VCC) at VCNP Body masses for BTPDs are from single Rankin Ridge Colony at Wind Cave National Park Body masses for UPDs are from single Horse Corral Colony at Bryce Canyon National Park Body masses from WTPDs are from single study colony at Arapaho National Wildlife Refuge Some data on BGUW sexual dimorphism are in the following publication: Hoogland, J. L. 2003.
