Abstract
We released juvenile Anolis aeneus lizards into vacant patches of habi tat in the field and observed as they established territories. Individ uals settling in the presence of few competitors obtained more exclusi ve home ranges than did individuals settling at higher densities. When settling at high densities, juveniles that eventually attained high s ocial status fought and chased their opponents more frequently than di d juveniles that were subordinate to other residents at the end of the settlement period. With respect to predicting an individual's final s tatus and space use, however, the fact that it fought other settlers w as more important than the outcome of those fights. Results from this and previous studies in this series are consistent with a general mode l of territory establishment that includes assumptions about the value of familiar space, the costs of aggressive interactions and the abili ty of settlers to form predictable social relationships with one anoth er.
