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

FILE DESCRIPTION Keywords: black-tailed prairie dog, Colony sizes and colony compositions by year File name = Fig 11.1, Top left, BTPDs, Colony sizes and compositions by year, 18 Dec 2025 OLDFile name = BTPDs, Colony sizes, 25 March 2020 Note that I have combined male and female yearlings into one group. I do this only for BTPDs Note: 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.

# 文件说明
关键词：黑尾土拨鼠（black-tailed prairie dog）、按年份划分的种群规模与种群结构
旧版文件名：BTPDs, Colony sizes, 2020年3月25日
当前文件名：图11.1（左上部分）、BTPD、按年份划分的种群规模与种群结构，2025年12月18日

备注1：仅针对黑尾土拨鼠，本次研究将雄性与雌性亚成体（yearling）合并为一组。此举原因在于：通常情况下，黑尾土拨鼠的雌雄亚成体不会进行交配，合并分组可避免图表过于杂乱。
备注2：本数据集对应每年5月的统计数值。
备注3：已排除1975年的数据（该年为我在兰金岭开展研究工作的第一年），但纳入了1989年的数据（当时吉姆·拉弗里（Jim Loughry）正在兰金岭工作）。
备注4：本文件于2020年3月25日由JLH单独核查两次。
备注5：本文件所有数据来自Hoogland 195年著作的表16.1（第377页）。需注意：本Excel文件中统计的出洞幼崽数量包含了从未被捕获但记录于Hoogland 1995年表16.1中的幼崽。
术语定义：
- 断乳幼崽（weanling）：首次从出生洞穴出入口出洞的幼体
- 种群规模：5月统计的成年个体与亚成体总数
- 本文件中，成年个体指年龄≥2岁的土拨鼠；亚成体指从出生育儿洞穴出洞已满9个月但不足20个月的年轻个体。
备注6：本数据集用于制作Hoogland 2026年著作中的图11.1。
备注7：本文件于2025年2月15日准备完毕，将进行长期存储。
备注8：本文件所有数据来自风洞国家公园内的BTPD兰金岭种群。
