Aggression in the Female Northern Elephant Seal, Mirounga Angustirostris
Abstract Maternal aggressive behavior of northern elephant seals enhances reproductive success by increasing the likelihood of pup survival. Detailed observations of marked mother-pup pairs revealed that female aggressiveness increased dramatically after giving birth. Maternal aggressiveness also co...
