ferent from that of LO. JB and LO had strong modes in 

 year class 7, whereas KL suggested a mode in year class 

 9 (Fig. 21. The abundance of year classes 10-22 at LO 

 was greater than that at JB (Fig. 2). 



Age structures of L. quinquelineatus also differed 

 significantly among reefs (Kruskal-Wallis statistic: 

 H=21A 1 , P<0.00 1 ). Kolmogorov-Smirnov tests (Table 

 4) showed that MR and LO were significantly differ-
