Many high latitude species dependent on sea ice are being forced to adapt to changing habitats. Harp seals (Pagophilus groenlandicus) are an indicator species for changing high-latitude ecosystems. This study analyzed multiple factors includ...

متن کاملThe Effects of Climate Change on Harp Seals (Pagophilus groenlandicus)
Harp seals (Pagophilus groenlandicus) have evolved life history strategies to exploit seasonal sea ice as a breeding platform. As such, individuals are prepared to deal with fluctuations in the quantity and quality of ice in their breeding areas. It remains unclear, however, how shifts in climate may affect seal populations. The present study assesses the effects of climate change on harp seals...

Despite the highly specialized nature of site use, it appears that reliance on harp seal decreased over time while fish and birds became increasingly important. These changes may reflect longer seasonal occupatio...
