Fig 3. Proportion of motile sperm (black solid line and dots) and proportion of SOD activity in sperm relative to the total SODsperm + RBCs (grey dotted line and triangles) after shuffling males across aviaries.
This relative sperm SOD activity is used as a proxy for the relative investment of antioxidant resources in soma vs. germline functions. Initial male social status: (a) dominant, (b) subordinate-1, (c) subordinate-2, and (d) subordinate-3 males. The lines connect the mean of each group, and are only illustrative. Proportions are logit-transformed.
