A favourable combination of a small effect of phylogeny and a considerable range of environmental conditions makes geographic variation among populations of widespread species a promising model for testing adaptive hypotheses. However, comprehensive range-wide studies of geographic variation in widespread species – even for so fundamentally important trait as body size - are rare. During this project I will document macrogeographic and regional patterns of variation in body size, sexual size dimorphism, and female reproductive output in two widely distributed and broadly sympatric lizard species, Lacerta agilis and Zootoca vivipara. Under careful consideration of potential confounding factors I will investigate relationships of these patterns with the environment (climate), with phylogeny, and among each other. In particular, several predictions of Darwin's fecundity-advantage hypothesis will be tested, and two prominent and currently debated patterns of body size variation, Bergmann’s rule and Rensch’s rule, will be addressed.

一个有利的组合，一个小的影响，繁殖和相当大的范围内的环境条件，使广泛分布的物种种群之间的地理变异的一个有前途的模型，用于测试适应性假说。然而，广泛分布的物种的地理变异的全面范围内的研究-即使是如此根本的重要性状的身体大小-是罕见的。在这个项目中，我将记录两个广泛分布和广泛同域的蜥蜴种，蜥蜴和胎生动物的身体大小，性别大小二型性和雌性生殖输出的变化的宏观地理和区域模式。在仔细考虑潜在的混杂因素，我将调查这些模式与环境（气候），与生育，以及彼此之间的关系。特别是，几个预测的达尔文的繁殖力优势假说将进行测试，两个突出的和目前有争议的模式的身体大小的变化，伯格曼的规则和Rensch的规则，将得到解决。
