Resumen

Mark-resight data were analysed for five cohorts (1997-2001) to estimate age-specific juvenile survival, age at first reproduction, and resight probabilities. Longitudinal histories of presence and pregnancy of adult females (aged by cementum annuli) were used to estimate age-specific survival and natality. Data on tagged juveniles were collected from 1998-2005 and for adult females from 2000-2005. These data are used to construct an age-dependent life table for female fur seals breeding at Cape Shirreff and to estimate net reproductive rate, mean generation time and the intrinsic rate of growth for the population.
