Adaptation to the afroalpine environment in Brassicaceae species with contrasting ecological strategies (B03)

东非的高山天空岛屿为研究多物种和山脉的趋同适应提供了独特的机会。耐逆A. alpina和ruderal A.在这些山脉中同时出现了拟南芥。我们将调查这些人群的人口统计学历史，比较他们的变化特征暴露于选择压力，随着海拔高度的变化，并检查他们的遗传结构。该项目将揭示两个生态上不同的物种暴露于相同的挑战性环境中的趋同适应的历史。

The alpine sky islands of Eastern Africa offer a unique opportunity to study convergent adaptation across multiple species and mountain ranges. Populations of the stress-tolerant A. alpina and the ruderal A. thaliana co-occur in these mountain ranges. We will investigate the demographic history of these populations, compare their variation for traits exposed to selective pressures that vary with elevation and examine their genetic architecture. This project will shed light on the history of convergent adaptation in two ecologically different species exposed to the same challenging environment.
