摘要：

We discuss a simple method, based on maximum likelihood, to estimate the rates of extinction and recolonization of a species, for example, on an island. Our method applies to both regular and sporadic surveys and thus allows one to use time series with missing data. When only a few surveys have been conducted, it may be possible to lump data from several species. The shape of the likelihood surface may indicate whether the lumping is appropriate.
