摘要: The investigation was designed to explore the structure, composition, and activity of a biological soil crust on an acidic, sandy from temperate climate. covers several hundreds square meters hilltop large terminal moraine. conjugate alga Zygogonium ericetorum forms essential matrix for crust, dense web algal filaments with interspersed lichens mosses. is composed three layers, uppermost layer consisting nearly entirely mat. In lower parasitic fungus, penetrating cells, another important component community. this photosynthetic respiratory stabilized at low water activities.
