个体发生的可塑性变化对于理解热耐受性变化的机制和模式具有重要意义。博格特效应假设，为了补偿它们在行为上的温度调节能力的不足，活动较少的变温动物的生命阶段预计会比活动较多的生命阶段表现出更大的热耐受性可塑性。我们通过比较16种果蝇的活动成虫和不活动幼虫的热耐受性（快速冷硬化，RCH）的可塑性来验证这一普遍预测。我们发现13种成虫有RCH反应，但只有4种幼虫有RCH反应。因此，博格特效应并不像预期的那样广泛。
Ontogenetic variation in plasticity is important to understanding mechanisms and patterns of thermal tolerance variation. The Bogert effect postulates that, to compensate for their inability to behaviourally thermoregulate, less-mobile life stages of ectotherms are expected to show greater plasticity of thermal tolerance than more-mobile life stages. We test this general prediction by comparing plasticity of thermal tolerance (rapid cold-hardening, RCH) between mobile adults and less-mobile larvae of 16 Drosophila species. We find an RCH response in adults of 13 species but only in larvae of four species. Thus, the Bogert effect is not as widespread as expected.
