Ecological niche differentiation is one of the important topics in modern zoological studies to distinguish the cryptic species and local adaptations. In this article, we provided results of niche modelling of two Phasianus colchicus groups in the Iranian plateau. We performed ecological niche modeling for each group separately and then calculated the niche overlap and compared the ecological niches of the groups. Precipitation of warmest quarter and mean temperature of coldest quarter were the most important factors in determining habitat suitability and niche divergence. Based on niche overlap analysis, separation of ecological niches between these groups has been confirmed. Consequently, ecological niche divergence may effect on the genetic divergence between groups by presenting a prezygotic barrier.

生态位分化是现代动物学研究中区分神秘物种和局部适应的重要主题之一。在本文中，我们提供了伊朗高原两个Ph属秋水仙属种群的生态位建模结果。我们分别对每组进行生态位建模，然后计算生态位重叠并比较各组的生态位。最暖季的降水和最冷季的平均温度是确定栖息地适宜性和生态位差异的最重要因素。基于生态位重叠分析，已经确认了这些群体之间生态位的分离。因此，生态位生态多样性可能会通过提供一个合子前屏障来影响群体之间的遗传差异。
