Fig. 8. Relative arginine kinase (AK) mRNA 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=45. 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.
