Figure 3.

Per capita number of eggs (number of eggs/number of adults) laid over 4 days (A, B), the proportion of eggs that emerged as adults (Proportion Survival; C, D), and the mean time to emergence of adult offspring (Mean Adult Emergence; E, F) by red flour beetles (Tribolium castaneum) at different temperatures (20, 25, and 30°C) and population densities. Treatments either had low food (0.625 mL flour; A, C, E) or high food (2.5 mL flour; B, D, F). N = 5 replicates for each treatment combination. The lines represent the linear lines of best fit for each treatment. Treatments at 20°C did not develop past the egg stage.
