This laboratory study was designed to examine the response of a postfire ascomycete community to elevated temperatures and treatment intervals corresponding to those recorded during the burning of a tallgrass prairie. Aerated steam treatment of prairie soil samples (35, 40, 55, 70, 85, or 100 °C) for intervals of 60, 100, 140, or 180 s enabled us to examine the response of individual species comprising the carbonicolous ascomycete community.Simulation of a grassland fire by aerated steam treatment of prairie soils promoted the development of 20 species of ascomycetes. Generalists such as Sporomiella subtilis Ahmed and Cain occurred at high frequencies over most of the temperature range while specialists Podospora curvispora (Cain) Cain, Sordaria macrospora Awd., and Leptosphaeria sp. were important at only one temperature. Species diversity, richness, and number of species per sample were significantly affected by the temperature of the steam treatment. The temperature–treatment interval combination allowing for the greatest expression of diversity in the carbonicolous ascomycete community was 55 °C for 60 s. Since a grassland fire does not uniformly heat the soil surface, the environmental patchiness created by this physical perturbation may be an important factor in determining the composition of the carbonicolous ascomycete community in prairies.

Edaphic Variables

ABSTRACTSoil microbial community characterization is increasingly being used to determine the responses of soils to stress and disturbances and to assess ecosystem sustainability. However, there is little experimental evidence to indicate that predictable patterns in microbial community structure or composition occur during secondary succession or ecosystem restoration. This study utilized a chronosequence of developing jarrah (Eucalyptus marginata) forest ecosystems, rehabilitated after bauxite mining (up to 18 years old), to examine changes in soil bacterial and fungal community structures (by automated ribosomal intergenic spacer analysis [ARISA]) and changes in specific soil bacterial phyla by 16S rRNA gene microarray analysis. This study demonstrated that mining in these ecosystems significantly altered soil bacterial and fungal community structures. The hypothesis that the soil microbial community structures would become more similar to those of the surrounding nonmined forest with rehabilitation age was broadly supported by shifts in the bacterial but not the fungal community. Microarray analysis enabled the identification of clear successional trends in the bacterial community at the phylum level and supported the finding of an increase in similarity to nonmined forest soil with rehabilitation age. Changes in soil microbial community structure were significantly related to the size of the microbial biomass as well as numerous edaphic variables (including pH and C, N, and P nutrient concentrations). These findings suggest that soil bacterial community dynamics follow a pattern in developing ecosystems that may be predictable and can be conceptualized as providing an integrated assessment of numerous edaphic variables.
