FIGURE 3 in Fish biomarker responses to perturbation by drought in streams
FIGURE 3 | MDA and enzymatic activity in the liver of Astyanax elachylepis from intermittent and perennial streams during dry and rainy seasons. Different capital letters indicate a significant difference (Tukey post-hoc test at p <0.05) between seasons for a given stream, and different lower-case letters indicate a significant difference between intermittent and perennial streams within a given season. Differences are shown only between levels of the factors that had significant effect according to two-way ANOVA.
