Seevögel im Südpolarmeer: Flexibel in einer Umwelt voller Herausforderungen.

Summary Seabirds face a number of challenges in Antarctic and Subantarctic breeding areas, such as variations in food supply and changes in the ecosystem due to climate change, aggregation and competition from the limited number of suitable breeding areas, and inaccessible breeding areas due to changes in precipitation. Adjustments to irregular food supplies, such as flexible incubation and nesting times, and torpor in chicks can help seabirds keep pace with changes occurring due to climate change. Data loggers are used to better understand the responses of adult birds to changes in the ecosystem and the resulting population trends. Various data loggers are used for a variety of applications, from one gram light loggers for long‐term tracking across large scales to high‐resolution GPS loggers with acquisition of acceleration data that can also be used to model energy expenditure. In order to fully understand the movement ecology of seabirds, several approaches need to be considered: ecological segregation in space, time and choice of food, energy landscapes and the non‐lethal effects of predation (landscapes of fear).
