Fig. 2. Ventricular properties following anemia and cold acclimation. The first
pair of bars is from animals sacrificed at 4 weeks, showing the effects of
anemia alone. The second set of bars represents the influence of anemic
pre-treatment on the effects of cold-acclimation. The effects of temperature
alone are apparent by comparing the untreated fish (solid bars). Based on
ANOVA, followed by Tukey's post-hoc, we identified groups that were
significantly different from controls at 4 weeks (*) or
(
) phenylhydrazine treated at 4 weeks.
