Weaning mass variation of southern elephant seals at king George Island and its possible relationship with "El Niño" and "La Niña" events
Possible effects of "El Niño" Southern Oscillation (ENSO) components "El Niño" and "La Niña" on populations of southern elephant seals, Mirounga leonina L., are considered in this study. Information on pup weaning mass, collected at King George Island, South Shetland Is...
