The study examines ecological niche differentiation among five Campanula species of the Heterophylla section in the Southwestern Alps. Two main climatic groups were identified, with C. sabatia showing minimal overlap at spatial, climatic, and microenvironmental levels. Conversely, C. stenocodon is at high risk of hybridization with C. cochleariifolia, emphasizing the need for targeted conservation actions to preserve genetic integrity.

Abstract
The study examines ecological niche differentiation among five Campanula species of the Heterophylla section in the Southwestern Alps. Two main climatic groups were identified, with C. sabatia showing minimal overlap at spatial, climatic, and microenvironmental levels. Conversely, C. stenocodon is at high risk of hybridization with C. cochleariifolia, emphasizing the need for targeted conservation actions to preserve genetic integrity.
