Past records and current distribution of seabirds at Larsemann Hills and Schirmacher Oasis, east Antarctica
Abstract Seabird populations in Antarctica serve as indicators to assess the impacts of global environmental change. Ecological data on seabirds in Antarctica are scarce due to limited knowledge on their distribution and abundance in most parts of the continent. In this study, we investigated the st...
