当物种改变它们的活动范围以跟踪气候变化时,它们几乎肯定会经历它们不太适应的新环境。Otaki和他的同事记录了苍草蓝蝴蝶在活动范围扩大的同时,翅膀图案变化的爆炸性变化。这种模式可以在实验室中复制,通过对冷休克蛹进行人工选择,在最近殖民环境中典型的极端温度下。我们讨论了这种表型可塑性如何与成功的殖民有关,以及局部适应如何可能重新建立发育控制。将性状可塑性的知识整合到当前的适应遗传模型中,对于我们理解殖民种群何时何地能够在新的环境中坚持和适应是核心的。
When species shift their ranges to track climate change, they are almost certain to experience novel environments to which they are poorly adapted. Otaki and co-workers document an explosion of wing pattern variation accompanying range expansion in the pale grass blue butterfly. This pattern can be replicated in the laboratory using artificial selection on cold shocked pupae, at temperature extremes typical of recently colonized environments. We discuss how this phenotypic plasticity may be associated with successful colonization and how significant local adaptation is likely to re-establish developmental control. Integrating knowledge of trait plasticity into current genetic models of adaptation is central to our understanding of when and where a colonising population will be able to persist and adapt in novel surroundings.
