Abstract

This work tested the hypothesis that the abundance of fungal species on coniferous needles is correlated to climatic factors at a regional scale. The proportions of Pinus sylvestris needles colonised by Lophodermium pinastri, Cyclaneusma minus and Verticicladium trifidum were examined along two altitudinal transects in 2 successive years. L. pinastri and C. minus colonisation increased with altitude, whereas that of V. trifidum decreased. The data are discussed in relation to the importance of climatic controls on species distributions.
