Most research on the social dynamics of wolf packs, however, has been conducted on wolves in captivity. These captive packs were usually composed of an assortment of wolves from various sources placed together and allowed to breed at will (Schenkel 1947; Rabb et al. 1967; Zimen 1975, 1982). This approach apparently reflected the view that in the wild, "pack formation starts with the beginning of winter" (Schenkel 1947), implying some sort of annual assembling of independent wolves. (Schenkel did consider the possibility that the pack was a family, as Murie (1944) had already reported, but only in a footnote.)
In captive packs, the unacquainted wolves formed dominance hierarchies featuring alpha, beta, omega animals, etc. With such assemblages, these dominance labels were probably appropriate, for most species thrown together in captivity would usually so arrange themselves.
In nature, however, the wolf pack is not such an assemblage. Rather, it is usually a family (Murie 1944; Young and Goldman 1944; Mech 1970, 1988; Clark 1971; Haber 1977) including a breeding pair and their offspring of the previous 1-3 years, or sometimes two or three such families (Murie 1944; Haber 1977; Mech et al. 1998).
...Attempting to apply information about the behavior of assemblages of unrelated captive wolves to the familial structure of natural packs has resulted in considerable confusion. Such an approach is analogous to trying to draw inferences about human family dynamics by studying humans in refugee camps. The concept of the alpha wolf as a "top dog" ruling a group of similar-aged compatriots (Schenkel 1947; Rabb et al. 1967; Fox 1971a; Zimen 1975, 1982; Lockwood 1979; van Hooff et al. 1987) is particularly misleading.
...Labeling a high-ranking wolf alpha emphasizes its rank in a dominance hierarchy. However, in natural wolf packs, the alpha male or female are merely the breeding animals, the parents of the pack, and dominance contests with other wolves are rare, if they exist at all. During my 13 summers observing the Ellesmere Island pack, I saw none.
Thus, calling a wolf an alpha is usually no more appropriate than referring to a human parent or a doe deer as an alpha. Any parent is dominant to its young offspring, so "alpha" adds no information. Why not refer to an alpha female as the female parent, the breeding female, the matriarch, or simply the mother? Such a designation emphasizes not the animal's dominant status, which is trivial information, but its role as pack progenitor, which is critical information.
...The typical wolf pack, then, should be viewed as a family with the adult parents guiding the activities of the group and sharing group leadership in a division-of-labor system in which the female predominates primarily in such activities as pup care and defense and the male primarily during foraging and food-provisioning and the travels associated with them (L.D. Mech, see footnote).[/b]
