I 3 4 5 6 7 8 9 10 II 5 6 7 8 Urn SECONDS Figure 7. Summary DAP graphs of Anolis distichus Type A and B displays. A^ and B,^ are the patterns from Montrouis in north and A^ and B are from Petion-ville in the south. Numbered boxes immediately under each DAP graph indicate duration and identity of bob and inter-bob units. Examples of interindividual display differences are given in Figure 8; these DAP graphs are summaries for three males for which I had the most displays. The display durations for the three males were made comparable by computing unit durations as a percentage of the total display duration. One sees that the posi- tion of homologous bobs between lizards' displays is somewhat variable and the average number of bobs performed for the multi-bob units also differs be- tween lizards. Yet it is evident that these DAP graphs are all Type A displays and cannot be confused with any of the other distichus display patterns (, the Type B displays also depicted in Fig. 8). The Type A display is considered the species' signature display by previously defined criteria (Jenssen, 1978). First, it is a well-defined stereotyped pattern shared by the population. Second, it was the most frequently performed display type; from the film record there were 60 A, 43 a, 29 B, 28 E, 18 C, and 14 D dis- plays. Last, it occurred during non- directed displaying associated with terri- torial patrol. The Type A display, as expected of the signature display, ap- peared in all other major social contexts: during courtship, copulation, and the im- mediate post-copulatory period, and dur- ing aggressive interactions between Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble
