Abstract: We update in this paper the previously reported model for the Antarctic fur seal ... developed at Cape Shirreff during 1998/99, but we could not census the San Telmo Islets. In this regard, we ... had to model the population at the latter site, in order to have a complete estimate of the population ... . From this, we estimated an overall increase of 17% in the total population, including in this figure a ...
