Sewall Wright, R. A. Fisher, and others have shown the influence of population size on the fluctuation in gene frequencies but have disagreed on the explanation for it. The ratio of the effective population number to the actual number is a measure of the extent to which parents make unequal contributions to succeeding generations. For the past few years I have been studying the population ecology and dynamics of the lizard Uta stansburiana stejnegeri in western Texas. During this time data have accumulated that will allow at least a crude estimate of effective number as distinguished from simple density. Because such estimates are largely unavailable for natural populations, the results of this study are presented here.
