Seasonal groupings of samples re- 

 vealed significant differences in the 

 analysis of variance (Table 3). When 

 the deepest station (LS) was included 

 in the analysis, the total number of 

 individuals were significantly differ- 

 ent with depth (P<0.05). This varia- 

 tion with depth can be explained by 

 the fact that, on average, fewer indi- 

 viduals were collected at the station 

 on theLS(P<0.01)(Fig. 4). 



Differences in the number of females 

 were also significantly related to depth 

 (P<0.05); females were more abundant 

 at shallower stations on the MS and 

 US. Males collected from the three 

 habitats exhibited significant differ- 

 ences for interaction between depth 

 and seasonality (P<0.05) (Table 3), 

 which resulted from the higher per- 

 centage of males on the LS all year and 

 on the MS in autumn and winter. 



When the deepest samples (LS) were 

 excluded, differences between the number of males 

 and the total number of individuals were significant 

 between seasons (P<0.05) and for the interaction 

 between depth and season <P<0.05).
