Changes of humus features along with a successional gradient of Rhododendron ferrugineum (L.) populations (subalpine level, northwestern Alps, France)
International audience The modifications of humus characteristics as a result of the establishment and the increasing cover of Rhododendron ferrugineum L. (Ericaceae) in a subalpine meadow were studied in three sites in the northwestern French Alps corresponding to a west-east transect between wet a...
