Fig. 2. (A) Copper and (B) total protein concentrations in hemolymph of L.
stagnalis as a function of time. Individuals were bled at time 0 (open
bars; N=54 for Cu, N=53 for proteins) and sub-groups (closed
bars) were bled again at 6 h (N=8 for Cu and N=6 for
proteins), 12 h (N=7 for Cu and N=8 for proteins), 1 week
(N=10 for Cu and total proteins), 2 weeks (N=10 for Cu and
total proteins), 5 weeks (N=10 for Cu and total proteins) and 10
weeks (N=9 for Cu and total proteins). Asterisks indicate values
significantly different from initial time point values. Values are means
± s.e.m.
