Figure 1.

Nutritional landscapes illustrating the effects of daily protein and carbohydrate intake on lifespan (A–D) and daily reproductive effort (E–H) in female (A, C, E, G) and male (B, D, F, H) crickets that were supplemented with DL-alpha-tocopherol (C, D, G, H) or not (A, B, E, F). High values of these traits are in red and low values in blue. The scale associated with each graph is shown to its right: the values for each scale bar are days (for lifespan), daily number of eggs laid (female reproductive effort) or time spent calling (male reproductive effort). Black dots represent the actual intake of nutrients by individual crickets.
