Antarctic fur seals feel climate impacts
An unusual opportunity is afforded by three decades of individual-based data collected from a declining population of Antarctic fur seals in the South Atlantic. Here, climate change has reduced prey availability and caused a significant decline in seal birth weight. However, the mean age and size of females recruiting into the breeding population are increasing.
The results provide compelling evidence that selection due to climate change is intensifying, with far-reaching consequences for demography as well as phenotype and genetic variation.
