dc.description.abstractEnKeywords: Biotrophic plan pathogen Ecological niche Oak Powdery mildews Species coexistence Temporal succession a b s t r a c t Recent molecular studies have shown that four genetic lineages, probably cryptic species, cause oak powdery mildew in Europe. We tested the hypothesis of niche differentiation between the two most frequent species (Erysiphe alphitoides and Erysiphe quercicola), by determining their relative prevalences at various times during the growing season. E. quercicola was strictly associated with the flag-shoot symptom in a 2-yr sampling campaign of 35 natural oak seedling populations. Additional sampling during Aug.eSep. in the same stands showed that E. alphitoides predominated in most (70 %) cases. Time-course monitoring of powdery mildew in two natural regenerating oak populations confirmed the inverse patterns of relative abundance for these two species in early and late season. The coexistence of these two closely related species may be due to the use of different strategies , resulting from a trade-off between overwintering (flag-shoots vs. chasmothecia) and late-season performance. ª
