Global climate drives southern right whale (Eubalaena australis) population dynamics

Global climate drives southern right whale (Eubalaena australis) population dyna

Sea surface temperature (SST) time-series from the southwest Atlantic and the El Nin˜o 4 region in the western Pacific were compared to an index of annual calving success of the southern right whale (Eubalaena australis) breeding in Argentina. There was a strong relationship between right whale calving output and SST anomalies at South Georgia in the autumn of the previous year and also with mean El Nin˜ o 4 SST anomalies delayed by 6 years. These results extend similar observations from other krill predators and show clear linkages between global climate signals and the biological processes affecting whale population dynamics
