Long-Lived Termite Queens Exhibit High Cu/Zn-Superoxide Dismutase Activity

Figure 3

Measurement of copper concentrations in R. speratus queens and workers. Queens () had significantly higher concentrations of copper than workers (; ). We used pooled samples, as described in Table S1, for several replications. White and black bars indicate workers and queens, respectively. Error bars represent SEM. Significance was measured by unpaired t-test ().
