Form, Function and Fitness: Multidisciplinary Evolutionary Biology Using Lizards as Models

如何解释种群和物种内部和物种之间繁殖成功的差异及其进化后果？在进化生物学中解决这个基本问题需要多学科的方法，包括生态学、遗传学、行为学和生物化学。以蜥蜴为模型，我将测试(I)雄性信号的变化在多大程度上反映了免疫基因型和应激耐受性的差异，（ii）父权在多大程度上由雄性基因或雄性雌性遗传相似性决定，（iii）后代的生存主要取决于基因还是母体投资，以及（iv）这些因素在种群和物种之间的相对重要性是如何变化的。

What explains variation in reproductive success and its evolutionary consequences, within and among populations and species? Addressing this fundamental question in evolutionary biology requires a multidisciplinary approach, integrating ecology, genetics, behaviour and biochemistry. Using lizards as models, I will test (i) the degree to which variation in male signals reflects differences in immunogenotype and stress tolerance, (ii) the degree to which paternity is determined by male genes, or male-female genetic similarity, (iii) whether offspring survival depends mostly on genes or on maternal investments, and (iv) how the relative importance of these factors vary among populations and species.
