Table 1.

Cumulative reproductive data (mean ± SE) upon dietary restriction in grasshoppers. ShamFD is fully reproductive, fully fed; ShamDR is fully reproductive, dietary restricted. The only consistent effect of DR on reproductive tactics was the reduction in the size of each clutch. Eggs/Clutch is the grand mean of the average number of eggs per clutch for each individual. Time/Clutch is the grand mean of the average time between clutches of eggs for each individual. Melanization is an immune response in which a hardened growth begins to encase the ovaries (Beckage 2008); counts are for presence/absence. LRE is Lifetime Reproductive Effort (Charnov et al. 2007); clutch size, average adult life span, and adult mass were the factors that impacted these scores.
