While the mother searches for food, the probability of the pups being attacked grows over time of being alone.
Finally, while females typically defend their pups against conspecific attacks and accidental trampling by males engaged in aggressive territorial behavior, they must spend a significant amount of time at sea to eat.
Attacks on pups decrease rapidly after they reach a less vulnerable stage [ 35].
That young little pup is now the Ravens' attack dog, the league's defensive player of the year, the 6-foot-1, 245-pound pile driver who seems to surround a ball carrier when tackling him.
It has been demonstrated that the reaction proceeds through a γ-glutamyl-phosphate mixed anhydride intermediate that is formed on the carboxy-terminal glutamate of Pup to activate it for nucleophilic attack by the lysine side chain [ 43].
Coyotes often attack humans to protect their pup's lives.
Another group called the Commandoes, led by a one-eyed male named Hannibal, introduced themselves by attacking the Lazuli burrow, killing a pup and badly wounding the babysitting adult.
Offspring raised by neglectful mothers were significantly less likely to protect their own pups in terms of expression of number of attacks against an intruder (Fig. 4D) (F 1,102) = 6.8, p = 0.01).
] PafA catalyzes pupylation in an ATP-dependent reaction, where the gamma carboxylate of Pup's C-terminal glutamate is phosphorylated prior to attack by a substrate lysine.
Tess too had noticed Camille and before I could stop her (my nails weren't dry yet), my pup did what she does best: A full-blown charm attack involving huge licks and excessive tail-wagging and Bambi eyes.
