Number of variables: 19 2. Number of cases/rows: 765 3. Variable List: RTL: relative telomere length measured by qPCR DNA.ID: unique code for each individual blood sample DNA.DATE: the date the blood sample was taken SAMPLING.PERIOD: a factor identifying (i) the breeding season (which runs from October to April inclusive) in which the blood sample was collected (e.g. 2009/10, 2010/11, 2011/12) and (ii) whether the sample was taken "early" (September to December) or "late" (January to May) in the breeding season. For example, "0910L" indicates the sample was taken "Late" in the 2009/10 season (i.e. between January and May 2010). Factor levels of this variable: 0910L, 1011E, 1011L, 1112E, 1112L, 1213E, 1213L, 1314E, 1314L, 1415E, 1415L PCR.PLATE.ID: ID of the PCR plate on which the sample was run. ID: ID of the sampled bird SEX: F for female, M for male BIRTH.CLUTCH: ID of the clutch in which the sampled bird hatched. AGE.CLASS: Factor identifying the age (in days) of the bird at sampling. Factor levels of this variable: 0-10 days, 11-89 days, 90+ days MOTHER.ID: ID of the mother of the sampled bird. MATERNAL.AGE.DAYS: estimated age of the mother (in days) at the lay date of the sampled bird's birth clutch. MATERNAL.MEAN.AGE.DAYS: the mother's mean age (in days) across all sampled clutches for that individual mother. MATERNAL.DELTA.AGE.DAYS: the difference (in days) between maternal age (MATERNAL.AGE.DAYS) and maternal mean age (MATERNAL.MEAN.AGE.DAYS). Calculated as MATERNAL.AGE.DAYS minus MATERNAL.MEAN.AGE.DAYS. FATHER.ID: ID of the father of the sampled bird. PATERNAL.AGE.DAYS: estimated age of the father (in days) at the lay date of the sampled bird's birth clutch. PATERNAL.MEAN.AGE.DAYS: the father's mean age (in days) across all sampled clutches for that individual father. PATERNAL.DELTA.AGE.DAYS: the difference (in days) between paternal age (PATERNAL.AGE.DAYS) and paternal mean age (PATERNAL.MEAN.AGE.DAYS). Calculated as PATERNAL.AGE.DAYS minus PATERNAL.MEAN.AGE.DAYS. DNA.EXTRACTION.DATE: the date that DNA was extracted from the blood sample. SAMPLE.STORAGE.DURATION.DAYS: the length of time (in days) the blood sample was stored in ethanol before DNA extraction. -----------------------------------------------------------------------------------------------------------------------------------------
