Fig. 5. Ratio of [Glycerol] in tissue (µmol ml–1 tissue
water)/plasma (µmol ml–1 plasma) in rainbow smelt
Osmerus mordax subjected to a controlled decrease in water
temperature. The date at which a controlled temperature decrease was initiated
(i.e. 15 January 2004) was used as day 0. The broken line represents equal
values for glycerol in tissue water and plasma. Asterisks indicate values
significantly different from 1.0. Water temperature (°C) on each sampling
day is shown on bottom panel in parentheses. Values are means ± s.e.m.,
N=4 for all points.
