摘要

In May and June 1997 the bodies of over 100 Mediterranean monk seals (Monachus monachus) were found along the Cap Blanc peninsula. This short stretch of coast, which spans the border between Mauritania and the former Western Sahara, is home to the largest surviving colony of these critically endangered creatures. The species' highly fragmented distribution extends as far east as the Black Sea, but the only other population of any size is over 4,000 km from Cap Blanc, in the eastern Mediterranean. Few ecologists were surprised when this mass mortality was attributed to infection with a previously undescribed morbillivirus, for viruses in this family have caused similar catastrophes in other species of marine mammal. The seals in the affected area are also virtually confined to two caves only about 1 km apart, so providing ideal conditions for the transmission ofinfection.
