Mycological studies of tropical forest (Ivory Coast) were carried out to evaluate, in permanent plots, the effects of edaphic and meteorological variability and of experimental disturbance, simulating shifting cultivation, on the soil mycoflora. In this paper spatial and temporal organization of these microfungal communities through diversity analysis is focused. Values of niche width and overlap, calculated for each type of soil and treatment considered, were analyzed for both intra- and interannual sequenc
