| 目前，生态学家越来越关注深入的生物学问题，例如，1）理解生态和进化过程的互作和关系；2）种群中一个重要的表型特征，受遗传基因影响多大？即其可遗传程度，表示该性状的进化潜能；3）基因是怎样影响表型性状，及其对应的个体适合度以及种群动态？4）决定多个重要表型性状的基因之间关系和互作如何？随着生物统计软件尤其是线性混合模型的发展，结合经典数量遗传学的理论，发展出了针对上述问题的动物模型（Animal Model），使得我们可以对野外种群进行上述研究。本文首先介绍了经典数量遗传学的重要概念，随后在其理论框架下，举例介绍了动物模型的操作和使用，最后探讨和展望了利用数量遗传学方法进行进化生态学研究的前景。 |
| 英文摘要: |
| Over the last decades field ecologists are more and more interested in understanding deeper biological questions, for instance: 1) the links between evolutionary and ecological dynamics. 2) For an important trait, to what extent determined by genes (as the degree of heritable reflecting the trait′s evolutionary potential)? 3) How do genes influence phenotypes, fitness and population dynamics? 4) How is the genetic correlation between important traits? As the development of biological statistics, especially the mixed effect model, combined classical theory of quantitative genetics, a professional model (Animal Model) provided us opportunity to carry out robust studies on wild populations. In this review, we introduce some basic conceptions of classical quantitative genetics, and then, by using typical examples, we focus on how to use the Animal Model. Finally, we discuss the future of integrating quantitative genetics and evolutionary ecology in the wild. |
