Table 5 DLC Weight File variable descriptions

1

Taxonomic code: In most cases, comprised of the first letter of the genus and the first three letters of the species; if taxonomic designation is a subspecies, comprised of the first letter of genus, species, and subspecies, and hybrids are indicated by the first three letters of the genus. See Table 1 for details.

2

Hybrid status: N=not a hybrid. S=species hybrid. B=subspecies hybrid. If sire is one of multiple possible and animal could be a hybrid, it is designated a hybrid.

3

Specimen ID: Unique DLC number assigned at accession of animal

4

Sex: M=male. F=Female. ND=Not determined

5

House name: Animal name assigned at DLC

6

Date of Birth: DOB is exact unless there is an entry in the ‘Estimated_DOB’ field.

7

Date of Birth estimate: Whether or not the date of birth is an estimate. Y=estimated to the nearest year, M to the nearest month, and D to the nearest day. If there is a number after the letter code, that indicates to the Nth value of the code. U=unknown. If there is no data in this field, DOB is not an estimate.

8

Weight: Animal weight, in grams. Weights under 500 g generally to nearest 0.1-1 g; Weights >500 g generally to the nearest 1-20 g.

9

Weight date: Date animal was weighed

10

Weight month: Month of the year the animal was weighed

11

Age in days: Age of the animal when the weight was taken, in days (Weight_Date-DOB)

12

Age in weeks: Age of the animal when the weight was taken, in weeks ((Weight_Date-DOB)/7))

13

Age in months: Age of the animal when the weight was taken, in months (((Weight_Date-DOB)/365)*12)

14

Age in months with no decimal: AgeAtWt_mo value rounded down to a whole number for use in computing average individual weights (FLOOR(AgeAtWt_mo))

15

Age in years: Age of the animal when the weight was taken, in years ((weight date-DOB)/365)

16

Days difference: Difference, in days, between the date of this weight and the date of the animal’s previous weight

17

Weight difference: Difference, in grams, between this weight and the animal’s previous weight

18

Average daily change: Average daily weight change, in grams, between this weight and the animal’s previous weight

19

Date of death. Verified date an animal died. Missing indicates animal is either alive or status is unknown.

20

Days before death: Number of days before the animal’s death the weight was taken (DOD-Weight_Date). Missing indicates animal is either alive or status is unknown.

21

Type of birth: Whether the animal was captive born (CB), wild born (WB) or of unknown birth type (UNK)

22

Birth institution: Name or ISIS abbreviation of institution where animal was born. Duke Prim=DLC. For wild caught animals, birth institution=country of origin, if known.

23

Litter size: Number of infants in the litter the focal animal was born into (including focal animal). Only indicated where verifiable (born at DLC). A missing value indicates that the litter size is unknown.

24

Dam minimum age at conception, in years, for the species from the life history summary table. Used to calculate ‘Age_Category’ as described below.

25

Age category: IJ (infant or juvenile): (AgeAtWt_yr<R_Min_Dam_AgeAtConcep_yr). Young-adult: (Min_Dam_AgeAtConcep_yr<=AgeAtWt_yr<2xMin_Dam_AgeAtConcep_yr). Adult: AgeAtWt_yr>=2xMin_Dam_AgeAtConcep_yr

26

Resident status: Whether or not the animal currently lives in the DLC colony

27

Pregnancy status: Whether or not animal is pregnant on date weight was taken. P=pregnant, NP=not pregnant (all males coded NP)

28

Expected gestation length: Values based on DLC observations and reports from the literature, in days

29

Conception date: Estimated date of infant conception if the weight was taken while a female was pregnant

30

Infant Date of Birth: Date of infant birth if the weight was taken while a female was pregnant

31

Days until birth: Days remaining in the pregnancy if the weight was taken while a female was pregnant

32

% of pregnancy remaining: Percentage of pregnancy remaining when weight was taken from a pregnant female calculated as (days_BF_inf_birth/Expected_Gestation)

33

Infant litter size: Number of infants in the litter a female produced if she was pregnant on date weight was taken
