8.3  Wednesday, Jan. 4   Staged Dominance Interactions Between Anolis carolinensis and Anolis sagrei Lizards. EDWARDS, JE*; LAILVAUX, SP; University of New Orleans, Louisiana; University of New Orleans, Louisiana

The introduced lizard Anolis sagrei is known to commonly replace Anolis carolinensis as the most abundant anole of urban areas and other open environments. To assess whether dominance behavior might play a key role in this change, we caught A. carolinensis and A. sagrei males of various sizes and randomly matched them in staged interactions in lab. Preliminary analyses suggest that the predictors of interspecific fight outcomes between A. carolinensis and A. sagrei are not straightforward, and appear to be different for each species.
