 likelihood of the data sets fitted with two wholly separate models. * = significant at a=0.05.

These conclusions agreed with the LRTs, which in- 

 dicated highly significant differences between g 20 be- 

 tween sexes at Lord's Bluff, and significant differences 

 between m and w at a=0.05 when tested individually 

 (Table 8B). This contrasts with the results of age-based 



modelling of sex-specific growth at Lord's Bluff, where 

 no difference between the sexes was detected in any 

 test. 



Sex comparisons at Point Bailey revealed no sex- 

 specific growth differences, and neither CIs (Table 7)
