Abstract: The limited access situation in which only one of two or more subjects can gain access to a reward during a restricted time-period is an accepted measure of dominance in the rat. This study attempts to validate the technique by establishing the relationship between individual and competitive performance in order to determine whether `priority of access' has been measured. The generality of the competitive orders is examined by altering the competitive response while retaining the same reward. In view of the data collected for both time and weight-gain measures in food and water competition it is doubtful whether the limited access competitive technique can be considered a valid measure of dominance for the laboratory rat.

Abstract: The use of competitive orders as measures of social dominance is examined, the conclusion being that such use is based on the assumption of the unidimensionality of social dominance. Evidence is presented to show that this is not always the case. Consequently it is suggested that each competitive order must be validated in terms of its measurement of priority of access and response requirements (internal validity) as well as its generality (external validity) before it can be regarded as a dominance measure. Problems of the validity of aggression orders as measures of social dominance are also examined along with their relationship to competitive orders.

Geist, V. (1974). On the Relationship of Social Evolution and Ecology in Ungulates. Amer. Zool., 14(1), 205–220.
Abstract: Much of the social behavior and organization of ungulates can be related to ecological parameters such as fiber content of forage, plant productivity, plant biomass, plant species diversity, productivity gradients, temporal and spatial fluctuations in productivity, habitat stability, food dispersion, three-dimensional structure of habitat, colonization, and predator density and diversity. These ecological variables can be linked via individual natural selection with the species' anti-predator strategies, emphasis on different channels of communication, relative frequency of damaging and non-damaging overt aggression, gregariousness and group structure, juvenile dispersal, home-range traditions, monogamy and polygamy, sexual dimorphism, territoriality, hierarchical rank structure, and plasticity of social structures. The ecological variables have primary manifestations which are behavior or which affect behavior, as well as secondary manifestations affecting behavior. There are logical links between the hypothesis linking ecology and behavior discussed here with some principles from bioenergetics, zoogeography, and paleontology. Although links do exist between ecology and behavior, they nevertheless represent distinct realms of natural selection in which social behavior appears as the more conservative element. The theoretical basis for this is discussed.
