assemblages for midsummer only (C) and late summer only (D). Solid lines within each figure box 
(A-D) enclose the boundaries of the identified assemblages. In A and B, each sampling station is 
identified by a different symbol and the arrows depict the gradient of each environmental variable. 
In C and D, species that occupy the same area of the graph are grouped by short lines and arrows 
denote their true locations. 
cal variables (Martino and Able, 2003; Jaureguizar et

case. Temperature and distance from the top of the 
ridge were often as important explanatory factors as 
depth, and habitat complexity and dissolved oxygen 
were also correlated with the distribution of fish along
