STUDIES ON THE SOUTHERN ELEPHANT SEAL, M I R 0 UNGA LEONINA (L.) V. POPULATIOX DYNAMICS AND UTILIZATION
The breeding population of Mirounga leonina (L.) a t Maoquarie Island is stable at about 36,000 cows and 3500-4000 bulls, with an annual maximum of the order of 110,000. Survival of branded weaned pups to the fourth year of life is over 40 % in both sexes: 20 % of females survive to the eighth year...
