 disputes (numbers of disputes are plotted against difference in size of anoles; 

 only those with a size difference of 8 mm or less are given) 



ciirred when an A. lineatopus attempted to establish an activity range 

 within the estabhshed activity range of a sHghtly smaller A. line- 

 atopus. The least severe conflicts occurred when a small A. line- 

 atopus moved to avoid a much larger individual that was ignoring it. 



This aspect of disputes is considerably more complex than out- 

 comes, and one important source of complexity is that the adult 

 males have a more elaborate set of aggressive displays than do the 

 rest of the population. No system of predicting the nature of dis- 

 putes can ignore this factor. The response of an A. lineatopus to 

 the initial display of its opponent also affects the nature of the dis- 

 pute that follows. 



The conditions under which disputes occur again show a strong 

 influence of relative size and place. The examples in the preceding 

 section have stressed this point. Again there are complicating 

 factors, e.g., an A. lineatopus is much more likely to behave aggres- 

 sively toward a moving and particularly a displaying individual 

 than toward one that is sitting quietly. 



Despite these complications, the same factors that are important 

 in predicting outcomes of disputes have important effects on the 

 moment when a dispute will occur and on the form it will take.
