Body size is a fundamental trait that shapes a species' development and evolution. Importantly, body size can also be affected by environmental variables, especially development temperature. Here we measure phenotypic plasticity in a series of lineages that had experienced artificial selection on body size for over 275 generations. We found, despite substantial changes in overall size and sexual size dimorphism, only modest effects on developmental plasticity. Still, there were some significant, changes in the sex specific slopes of the relationship between size and rearing temperature, largely due to a reduction in plasticity in the treatment selected for small body size.
体型是塑造一个物种发育和进化的基本特征。重要的是，体型也会受到环境变量的影响，尤其是发育温度。在这里，我们在一系列经过275代以上体型人工选择的谱系中测量表型可塑性。我们发现，尽管总体大小和两性体型差异发生了显著变化，但对发育可塑性的影响却很小。不过，大小与饲养温度之间关系的性别特异性斜率仍有一些显著变化，这主要是由于选择用于小体型的处理中可塑性降低所致。
