BTPDs, Females, yearlings produced in single year Frequency of this number of yearlings 0 349 1 64 2 73 3 48 4 16 5 0 6 1 FILE DESCRIPTION Keywords: BTPDs, Females, Yearlings in single year File name = Fig 13.2, Upper left, BTPDs, Females, yearlings in single year, 25 March 2026 OLD File name = Fig 13.2, BTPDs, Females, yearlings in single year, 24 Feb 2025 This file contains information for females that copulated but did not wean a litter (litter size = 0).

Yearlings = number offspring that survived for >=9 months after first emergence = = emergence from natal nursery-burrow. This file contains information from only those females known or inferred to copulate with at least one male during the mating season--i.e., yearling BTPD females that did not copulate are NOT considered in this EXCEL file I considered data from the same female in different years to be independent. Frequency of 6 yearlings = 1 is correct.
