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跨越多种物种和山脉的融合适应提供了独特的机会。在这些山脉中，耐逆性高山相思和原始相思相伴出现。我们将调查这些种群的人口学历史，比较它们在选择压力下的变异，这些特性随海拔变化而变化，并检查它们的遗传结构。这个项目将揭示两个生态上不同的物种在同样具有挑战性的环境中进行趋同适应的历史。

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.
