我们扩展的方法，数量遗传学的研究定义在连续的环境中的反应规范的演变。我们的模型考虑了空间变化（硬选择和软选择）和时间变化（一代人内和两代人之间）。这些不同形式的环境变化可以产生不同的进化轨迹，即使它们有利于相同的最佳反应规范。当遗传约束限制了反应规范可用的进化变化类型时，不同形式的环境变化也可以产生不同的进化平衡。这里提出的方法和模型提供了一个框架，在这个框架中，化学家可以确定反应规范是否是最优的，如果不是，则评估为什么不是的假设。
We extend methods of quantitative genetics to studies of the evolution of reaction norms defined over continuous environments. Our models consider both spatial variation (hard and soft selection) and temporal variation (within a generation and between generations). These different forms of environmental variation can produce different evolutionary trajectories even when they favor the same optimal reaction norm. When genetic constraints limit the types of evolutionary changes available to a reaction norm, different forms of environmental variation can also produce different evolutionary equilibria. The methods and models presented here provide a framework in which empiricists may determine whether a reaction norm is optimal and, if it is not, to evaluate hypotheses for why it is not.
