Morbillivirus neutralizing antibodies in Scottish grey seals (Halichoerus grypus): assessing the effects of the 1988 and 2002 PDV epizootics.
Phocine distemper virus (PDV) may have killed a small number of grey seals Halichoerus grypus in European waters in 2002, as it was thought to have done in 1988. PDV is known to affect harbour seal population and distribution patterns, but grey seal pup production trends did not correlate consistent...
