Abstract

Each year, billions of animals migrate across the globe on diverse spatial and temporal scales. Migration behavior thus plays a fundamental role in the life cycle and Darwinian fitness of many organisms. While the influence of migration on early-life survival and reproduction is well documented, its effects on senescence (aging) in advanced age remain largely unexplored. Using a unique 44-y ring-resighting dataset from a long-lived, partially migratory bird species, the Greater Flamingo (

Research summary

Migration influences the senescence process in long-lived birds. The study explores how migration behavior affects aging, which is directly related to understanding the mechanisms of longevity and aging processes.
