were examined in detail (Table 5). Relative abundances of 
fishes changed over the course of the study in both 1997 
and 1998 (Fig. 3). Three factors (species assemblages) were 
retained from the PCA of the relative abundance matrices 
in each year. In 1997, MANOVA and post hoc comparisons 
of mean factor scores indicated a significant temporal ef- 
fect on factors 1 and 2 (Wilk’s lambda=0.198, PcO.OOOl).
