| Popis: | The most common pattern of succession in the most recently active dunes along the southern shore of Lake Michigan is the formation and stabilization of dunes by marram grass, Ammophila breviligulata, the decline of this population after stabilization and its eventual replacement by little bluestem grass, Andropogon scoparius var. septentrionalis. The previously reported distribution of funigi from the sand at 15 cm below the surface in two adjaceint communities which represent these stages has been confirmed and the generality of the distribution established for other similar communities of this region and the Warrenl Dunes State Park in southwestern Michigan. A characteristic fungal flora was isolated from tne sand of the Andropogon communities, and 5 fungal species were found to be part of the flora in every one of the commuinities investigated. No such characteristic flora could be detected in the Ammophila communities. Monthly samples indicated no seasonal variations in the numbers and composition of the fungal flora. The presence of a characteristic fungal flora in the Andropogon communities and its absence in the Ammophila communities indicates a successional trend from a harsh, unstable environment, low in available mineral and organic matter content, to one more stable and suitable for fungal growth. |
