520 3# ‡aDiscusses effect of temporal variability in physical environment of southwest Atlantic sector of Southern Ocean on predator breeding performance. Sea-surface temperature at South Georgia shows periodicity of approximately 3 - 4 years, and variability at South Georgia also reflects temperature fluctuation in Pacific. Increased krill biomass at South Georgia coincides with cold periods, whereas periods of reduced predator breeding performance are strongly correlated with warm anomaly periods, though these lag behind by a number of months. For some predators, most critical periods appear to be prior to breeding season during summer and early autumn of preceding year. Such relationships between predator breeding performance and physical environment probably reflect prey (krill) availability.
