Inversion maternal en el elephante marino del sur en la isla 25 de Mayo, Antartida
Mass loss by females and changes in the body composition of their pups were measured during lactation in southern elephant seals, Mirounga leonina, at King George Island, South Shetland Islands. Mothers lost 10.78±2.07 kg/day (n=6), while theor pups gained 5.18±1.5 kg/day. The period measured (19±0....
