Norcross et a I.: Habitat models for juvenile pleuronectids

Discussion 
Our results show that relations among flatfish dis- 
tributions and habitats found within the geographic 
restrictions of eastern Kodiak Island in 1991 can be 
applied more broadly to other areas around Kodiak 
Rock sole 
Figure 5 
Pruned regression tree for age-0 rock sole with predictions of log(CPUE+l) at each terminal 
node, and number of stations in parentheses (top figure). Bottom figure contains box plots of 
log(CPUE+l) by terminal node. Each box plot summarizes distribution of CPUE at stations rep- 
resented by the terminal node directly above it. Box plots indicate median (filled circle), 
interquartile range (box height), and outliers (open circles). Whiskers indicate upper quartile 
plus 1.5 times interquartile range and lower quartile minus 1.5 times interquartile range. Width 
of boxes is proportional to square root of number of stations at that node. See text for sediment 
abbreviations.
