Causes and consequences of variation in age at first reproduction in barnacle geese, RiS ID 10651

I aim to disentangle the causes and individual-level consequences of age at maturity, which varies considerably between individuals, sexes and years (Loonen unpubl.). My main data source will be mark-recapture data from the Ny-Ålesund barnacle geese population, providing individual-based information on annual reproduction (nesting information, number of eggs laid, chick survival, chick recruitment) and survival. The data are collected on the islands in Kongsfjorden and in Ny-Ålesund.
