Fig. 7. Relative Na+/K+-ATPase
-subunit (NAK)
expression in anterior (G3, white bars) and posterior (G7, black bars) gills
of Callinectes sapidus acclimated to 35 p.p.t. (t=0) and at
various times after being transferred to 15 p.p.t. Values are means ±
s.e.m., N=414. Letters above bars indicate statistical
comparisons within G7 across the time course: two columns not sharing at least
one same letter are statistically different (P<0.05, two-way
ANOVA, Fisher LSD's post-hoc test). There were no significant
differences among G3.
