| Summary: | Individuals in species with long-term social monogamy often incur fitness costs after mate change. We evaluated the relative contributions of mate familiarity and male breeding experience to the costs of mate change of female black brant geese (Branta bernicla nigricans). We assessed the effects of mate change on relative nest initiation date, clutch size, brood size at hatch, growth rates of goslings, and prefledging survival of offspring. We modeled variation in relative nest initiation dates, clutch size, initial brood size, and gosling growth rates using generalized linear mixed models in Program R. We estimated prefledging survival with Cormack–Jolly–Seber models in Program MARK using reencounters of webtagged goslings. Mate change had a small effect on relative nest initiation date, clutch size, and initial brood size, but no effect on growth rates of brant goslings. Females breeding with an unfamiliar, but experienced male had goslings with higher prefledging survival rates (ϕ = 0.44±0.11 [95% ... : CJS_FINALThis data file was used to estimate prefledging survival and growth rates of black brant goslings as a function of their Mother's PAIRSTAT in Leach and Sedinger (2016). Each row represents a gosling. Data fields: CH=gosling capture history; MOTHER=mother's tarsal band; BRA = brood rearing area typically used by mother (see paper); GAGE = gosling age (days) at capture; GBM = gosling mass at capture; GSEX=sex of gosling; GBD = brood rearing area where gosling was captured; PAIRSTAT (see paper): FUTCHG = Pre-switch; EXP = unfamiliar, male experienced; NON = unfamiliar, male not experienced; MALE indicates if the father was unmarked.CS_FINALThis file was used to estimate Clutch size, Relative nest initiation date, and brood size at hatch (GLN) as a function of the mother's PAIRSTAT in Leach and Sedinger (2016).
