The impact of maternal experience on post-weaning survival in an endangered arctic fox population
Abstract Behavioural differences in parental care can influence offspring survival through variation in e.g. antipredator behaviour and ability to provide food. In a broad range of species, offspring survival has been found to be higher for experienced females compared to inexperienced first-time br...
