Degradation of mycorrhizal fungal communities associated with cork oak and understory vegetation by the anthropogenic factors

Abstract The cork oak ( Quercus suber L.) forests are ecosystems of high environmental and socioeconomic value in the Mediterranean basin. However, Algeria, highly threatened by repeated fires, overgrazing anthropogenic pressure that weaken ecosystem affect its natural regeneration. This degradation results an alteration many ecological components oak, such as fungal communities soil. Thus, aim this work is to study effects stand on diversity mycorrhizal associated with some understory shrubs Cistus monspeliensis , Lavandula stoechas Thymus vulgaris ) forest Brabtia (northeastern Algeria).For purpose, two sites were chosen: one degraded factors other non-degraded one. Moreover, it suggested plants shrub vegetation cistus, lavender thyme, prove be favourable juvenile growth tree. obtained showed ectomycorrhizal (EcM) root colonization cistus was higher compared both stations. estimation arbuscular (AM) significantly levels roots thyme station In contrast, rhizosphere soils had low number AM propagules spores, while under these parameters greatly improved abundance genera Glomus Gigaspora . These underline need take into account plant–fungus interactions development restoration strategies ecosystems.
