Fig. 4. Effects of a rapid increase in environmental salinity (FW to 21 p.p.t.; 605 mOsm kg^–1) on (A) plasma osmolality (mOsm kg^–1), (B) blood haematocrit (%) and (C) plasma angiotensin concentration (pmol l^–1) of river lampreys (N=8 at each time point: 0 h, 2 h, 4 h, 8 h and 24 h after transfer). Groups with different letters differ significantly (ANOVA and post-hoc multiple comparison tests). Asterisks signify groups that differ significantly from time 0 h(^*P<0.05, ^**P<0.01, ANOVA followed by linear contrast analyses).
