Persistence thresholds for phocine distemper virus infection in harbour seal Phoca vitulina metapopulations
1. This paper explores the concept of the critical community size for persistence of infection in wildlife populations. We use as a case study the 1988 epidemic of phocine distemper virus in the North Sea population of harbour seals, Phoca vitulina . 2. We summarize the available data on this epidem...
