Fig. 6

Example of tracked sunfish diving behavioural patterns and respective water column structure. Left panel shows the time at depth occupied by sunfish; central panel the corresponding TAT profiles; and right panel displays the water column structure—black line, determined from the recorded depths and temperatures, with dashed lines representing mean ± 1 SD. The three diel behaviours are a reverse DVM in frontal waters; b normal DVM in mixed waters; c surface-oriented behaviour in stratified waters
