Prehistoric remains reveal a drastic shift in northern fur seal ecology
...pearance of northern fur seals from some temperate regions
coincided with the arrival of Russian and European fur traders about 200 years ago. But in central and northern California, fur seal populations collapsed about 800 years ago, long before European contact. The cause of the earlier collapse remains un...
