Data from: "Contrasting drivers of reproductive ageing in albatrosses" H Froy, S Lewis, DH Nussey, AG Wood & RA Phillips (2017) Journal of Animal Ecology. Data are uploaded separately for different analyses. IDs and years have been recoded. "MeanAnnualBS" Data used to calculate mean annual breeding success for each species (Figure S1) Year Fledging year BBA_BS Mean fledging success of BBA GHA_BS Mean fledging success of GHA WA_BS Mean fledging success of WA "FailureStage" Nest outcomes, used to calculate proportion of failures that occurred during incubation vs chick rearing for each species NestOutcome (Success + Fail = Total) (FailIncubation + FailChickRearing + FailUnknown = Fail) BBA Number of observations of BBA GHA Number of observations of GHA WA Number of observations of WA "AFRALR" Data used to calculate mean age at first and last reproduction for each sex and species (Table 1) ID Individual identity (recoded) Species BBA = black-browed albatross; GHA = grey-headed albatross; WA = wandering albatross Sex F = female; M = male RingYear Year individual was ringed (usually fledging year, but in some cases first year observed) AFR Age at first reproduction (in years) ALR Age at last reproduction (in years) "BreedingSucAge" Data for the population-level analysis, used to model age-related variation in breeding success for each sex and species (Figure 2; Table S1; Table S2) ID Individual identity (recoded) Species BBA = black-browed albatross; GHA = grey-headed albatross; WA = wandering albatross Sex F = female; M = male Year Observation year (recoded as factor) Age Age (in years) BreedSuc 1 = chick successfully fledged; 0 = nest failed "BreedingSucAgeBothSexes" Data for the population-level analysis where the age of both parents was known, used to compare the explanatory power of male and female age for each species (Table S3) ID_F Individual identity of female (recoded) ID_M Individual identity of male (recoded) Species BBA = black-browed albatross; GHA = grey-headed albatross; WA = wandering albatross Year Observation year (recoded as factor) Age_F Age of female (in years) Age_M Age of male (in years) BreedSuc 1 = chick successfully fledged; 0 = nest failed "EarlyAdulthood" Data for the analysis of factors underpinning breeding success in early adulthood for each sex and species (controlling for selective appearance) (Table 2a; Table S4) ID Individual identity (recoded) Species BBA = black-browed albatross; GHA = grey-headed albatross; WA = wandering albatross Sex F = female; M = male Year Observation year (recoded as factor) YearSinceFirst Years since first breeding attempt FirstBreedingAttempt 1 = first breeding attempt; 0 = subsequent breeding attempts AgeFirstRepro Age at first reproduction (in years) BreedSuc 1 = chick successfully fledged; 0 = nest failed "LateAdulthood" Data for the analysis of factors underpinning breeding success in late adulthood for each sex and species (controlling for selective disappearance) (Table 2b; Table S5; Table S6; Table S7) ID Individual identity (recoded) Species BBA = black-browed albatross; GHA = grey-headed albatross; WA = wandering albatross Sex F = female; M = male Year Observation year (recoded as factor) YearBeforeDeath Years before final breeding attempt LastBreedingAttempt 1 = last breeding attempt; 0 = previous breeding attempts AgeLastRepro Age at last reproduction (in years) PartnerChange 1 = first breeding attempt following partner change; 0 = other breeding attempts YearSinceLast Years since previous breeding attempt PrevBreedSuc 1 = previous breeding attempt successful; 0 = previous breeding attempt unsuccessful BreedSuc 1 = chick successfully fledged; 0 = nest failed
