Data from : Environmental predictability drives adaptive within- and transgenerational plasticity of heat tolerance across life stages and climatic regions

Although environmental variability and predictability have been proposed as the underlying ecological context in which transgenerational plasticity (TGP) arises, the adaptive significance and interaction with within-generation plasticity (WGP) in such scenarios is still poorly understood. In order to investigate these questions, we considered the tolerance to upper thermal limits of larvae and adults of the desert endemic Drosophila mojavensis adapted to different climatic regions (Desert vs Mediterranean climate). Thermal plasticity was investigated by acclimating parents and offspring at 36°C (versus at 25°C). We then used historical temperature variation data from both regions to perform individual-based simulations by modeling expected components of adaptive plasticity in multiple life stages. Thermal response to ramping heat shocks was more pronounced in larvae, where acclimation treatments in parents and offspring increased their heat-shock performance, while heat knockdown in adu...尽管环境变异性与可预测性已被提出为跨代可塑性（Transgenerational Plasticity, TGP）产生的核心生态背景，但此类场景下其适应性意义及其与当代可塑性（Within-Generation Plasticity, WGP）的相互作用仍未得到充分解析。为探究上述科学问题，本研究选取适应于不同气候区域（沙漠气候与地中海气候）的沙漠特有莫哈维果蝇（Drosophila mojavensis），对其幼虫与成虫的高温上限耐受性展开研究。通过将亲本与后代分别在36℃（对照为25℃）下进行温度驯化，以探究其热可塑性。随后，我们利用两个区域的历史温度变化数据，通过对多生命阶段适应性可塑性的预期组成部分进行建模，开展基于个体的模拟实验。幼虫对渐升热冲击的热响应更为显著：亲本与后代的驯化处理均提升了其热冲击表现，而成虫的热击倒（heat knockdown）……
