Pack (canine)
Animals which typically predominate over others are associated with the term "alpha". Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition.
Julie's Wolf Pack
The Avaliks are forced to leave Silver behind so they can confront the rival pack, the wolves of Nuka River. In the fight that occurs between Kapu and the Nuka pack's alpha, Low Wind, Sweet Fur Amy and Aaka capture two Nuka wolves and bring them over to their side. The wolves, Storm Call and his sister Lichen, are the offspring of Low Wind and his mate Moon Seeker. The Avalik wolves accept them into their pack, and they return to Kangik, where they come across the strange wolf Ice Blink, and Silver′s now-lifeless body. Ice Blink offers to join the pack, but Kapu shoots her offer down, sensing something off about her. But after a while, since their pack numbers are low, Kapu reluctantly allows her to join.
