我们正在介绍一项关于地理单性生殖的研究，这是一个神秘而充满争议的现象。基于大样本的毛茛kuepferi的自然种群，这是第一个定量的，以人口为基础的评估整个阿尔卑斯山的繁殖模式，以测试海拔和地理距离模式的相关性。令人惊讶的是，我们发现了一个高的差异，在细胞型之间的繁殖模式，并可以给二倍体自然种群的无融合生殖的第一个证据。此外，一个显着的相关性倍性海拔被发现，以及相关性的繁殖模式的环境梯度。
We are presenting a study on geographical parthenogenesis, an enigmatic and much disputed phenomenon. Based on a large sampling of natural populations of Ranunculus kuepferi, it is the first quantitative, population-based assessment of mode of reproduction throughout the Alps to test for correlations to elevation and to geographical distance patterns. Surprisingly, we found a high variance in the modes of reproduction among cytotypes and can give the first evidence of apomixis in diploid natural populations. Further, a significant correlation of ploidy to elevation was found, as well as the correlations of mode of reproduction to environmental gradients.
