######The data file contains the following sheets: - BloodCoverage&HatchingParameter: Data used to examine the correlation between egg blood coverage and several parameters of reproductive success during the years 2012-2016 - ExperimentToReduceFlea#: Data used to investigate the effectiveness of microwaving nests on adult flea and flea larvae numbers - ExperimentalEffectNestParameter: Data used to investigate experimental effects on several parameters of reproductive success - Total#ofMovements: Data used to examine whether experimental groups differed in the total number of movements made by the geese as an indication for irritation - #Absences_per_day: Data used to find out whether the experimental groups differed in the number of absences per day - AbsenceTime_per_Day: Data used to investigate whether the experimental groups differed in the absence time per day - Preening&NestMaintenance: Data used to investigate whether there was a difference between the experimental groups in anti-parasite related behaviours: we examined the probability that the detected behaviour was preening or nest maintenance - Nest_Temperature: Data used to investigate experimental effects on daily average nest temperature and nest temperature fluctuations (in degrees Celsius) ####### Meaning of the column names in each datafile: ##sheet: BloodCoverage&HatchingParameter # columns: photo: a unique id for each photo used to estimate blood coverage datephoto: date when the photo of the nest was taken island: island on which the nest was located (PH = Prins Heinrichøya, SH = Storholmen) year: the year the data were collected nest: yearly unique nest id success: 0 = no hatch, 1 = successful hatch hatchlings: the number of hatchlings encountered in the nest during nest checks not_hatchlings: the number of eggs not seen as hatchlings blood_coverage: estimated egg blood coverage clutch_size: the maximum number of eggs in the nest during at least two subsequent visits eggspredated_breeding: the number of eggs that were predated during breeding (partial predation) eggsnotpred: the number of eggs that were not predated during breeding ##sheet: ExperimentToReduceFlea# # columns: nest: unique nest id flea: the number of adult fleas in the nest sample larvae: the number of flea larvae in the nest sample nestmass_dry: dry mass of the nest sample treatment: co = control nests, ex = flea-reduced nests sample_date: date when the nest was sampled days_after_exp: sampling moment; with 0 being the sampling moment just before the experiment, and 2 & 24 being 2 & 24 days after the experiment ##sheet: ExperimentalEffectNestParameter # columns: nest: unique nest id treatment: co = control nests, ex = flea-reduced nests success: 0 = no hatch, 1 = successful hatch blood_coverage: estimated egg blood coverage hatchlings: the number of hatchlings encountered in the nest during nest checks not_hatchlings: the number of eggs not seen as hatchlings eggspredated_breeding: the number of eggs that were predated during breeding (partial predation) eggsnotpred: the number of eggs that were not predated during breeding hatchafterexp: the number of days after the experiment when nests successfully hatched ##sheet: Total#ofMovements # columns: treatment: co = control nests, ex = flea-reduced nests nest: unique nest id days_since_exp: number of days before/after the experiment count: the total number of photos taken of control and flea-reduced nests per day (irrespective of photo quality) ##sheet: #Absences_per_day # columns: nest: unique nest id days_since_exp: number of days before/after the experiment treatment: co = control nests, ex = flea-reduced nests CountOfrecess_num: the summed number of absences per nest per day ##sheet: AbsenceTime_per_Day # columns: nest: unique nest id days_since_exp: number of days before/after the experiment treatment: co = control nests, ex = flea-reduced nests tot_time_away: time absent; the summed time the female was absent in seconds per day ##sheet: Preening&NestMaintenance # columns: ID: a unique id for the data record datum: date on which the photo was taken time: time when photo was taken nest_maintenance: female is on her nest with her bill in the nest material, often also her entire head is in the nest; 1 = presence of this behaviour, 0 = absence of this behaviour preening: female is on her nest preening her feathers (bill in feathers); 1 = presence of this behaviour, 0 = absence of this behaviour nest: unique nest id days_since_exp: number of days before/after the experiment treatment: co = control nests, ex = flea-reduced nests ##sheet: Nest_Temperature # columns: nest: unique nest id datum: date on which the measurement was done treatment: co = control nests, ex = flea-reduced nests AvgOftemp: Average daily temperature per nest StDevOftemp: Standard variation in temperature per nest days_after_exp: number of days before/after the experiment
