Genetic limits to evolutionary change are a fundamental issue for plant and animal improvement, as well as understanding how natural populations may respond to human-induced changes such as habitat degradation and climate change. Because we still know very little about how genetic variation is distributed among the multiple traits that are likely to respond to selection in such circumstances, we have no way of directly measuring the evolutionary potential of any natural population. In this proposal, we develop the theory, statistical tools, and experimental designs to investigate the nature and prevalence of these multivariate genetic constraints.

进化变化的遗传限制是动植物改良的一个基本问题，也是了解自然种群如何应对栖息地退化和气候变化等人类引起的变化的一个基本问题。因为我们对遗传变异是如何在多种性状中分布的知之甚少，而这些性状很可能在这种情况下对自然选择作出反应，所以我们没有办法直接衡量任何自然种群的进化潜力。在本提案中，我们发展了理论，统计工具和实验设计来调查这些多变量遗传约束的性质和流行程度。
