摘要: We report laboratory studies that aim to characterize the microphyte community composition and metabolic features of crusts covering dunes in Negev. The are formed by at least one moss, four blue-green (Cyanobacteria) two green (Chlorophyta) algal species with Microcoleus sociatus being dominant. sheaths latter procaryotic alga, together a contribution moss rhizoides protonemata, responsible for stability topsoil crusts. Following moistening dry crust, CO 2 release took place, even light, until positive net photosynthesis was achieved (...)
