Vessels in a Rhododendron ferrugineum (L.) population do not trace temperature anymore at the alpine shrubline
Introduction Mean xylem vessel or tracheid area have been demonstrated to represent powerful proxies to better understand the response of woody plants to changing climatic conditions. Yet, to date, this approach has rarely been applied to shrubs. MethodsHere, we developed a multidecadal, annually-re...
