Dose–response relationships showing effects of early-life γ-radiation exposure on measures of reproductive investment in adult Acheta domesticus: rate of reproductive effort (eggs laid × mg × day⁻¹) in early (A) and late (B) adulthood, lifetime fecundity (C), dry ovary mass (mg), and an estimate of total reproductive investment (D). All crickets were irradiated at 14 days of age at 0, 0.5, 1, 2, 4, or 5.5 Gy (dose rate = 0.25 Gy/min). Values are presented as body size-corrected residuals. All values are means ± standard error of the mean (SEM).
