Fig. 6. Whole-body Na+ uptake rate in neonate and adult water flea
Daphnia magna after pre-exposure to 4,4'
diisothiocyanostilbene-2,2' disulfonic acid (DIDS, 10–3
mol l–1), diphenylamine-2-carboxylate (DPC,
10–3 mol l–1) or acetazolamide (Aceta,
10–3 mol l–1). Data are expressed as mean
± 1 s.e.m. (N=6). Note the different axis scale for neonate
(left) and adult (right) daphnids.
