“…However, the time frame for the detection of recovery trends in the soil bacterial community following extreme disturbance is still beyond a decade. This time frame is similar to that required for microbial biomass recovery in rehabilitation forest soils and roughly comparable to indications elsewhere of 20 to 30 or more years for bacterial community recovery after a disturbance (27,33,43).…”

“…However, in comparison to plant communities, there is limited experimental evidence that predictable patterns in the microbial community structure or composition occur during secondary succession (18,37) or ecosystem restoration (27,33). Microbial communities are able to respond more rapidly than plant communities to changes in environmental conditions and may provide an early indication of the recovery trajectory (29).…”

“…Microbial communities are able to respond more rapidly than plant communities to changes in environmental conditions and may provide an early indication of the recovery trajectory (29). However, the high level of sensitivity to numerous environmental factors can also result in long-term shifts (in the order of decades or more) in the microbial community structure in rehabilitated ecosystems (33). Following extreme disturbances, such as mining, even best-practice rehabilitation programs may be expected to leave a soil legacy in terms of some alteration to the soil organophysicochemical environment.…”

Soil 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.

“…It was also an abundant OTU at NCP and was present in lower levels at CNH and SCD ( Table 2). Moreover, this OTU is also very similar to clones retrieved from agricultural land in Georgia, USA (21,22), river land dunes in Georgia, USA (46) and forest soils in Yunnan, China (10). The genus Rhodoplanes consists of a group of purple non-sulfur, denitrifying bacteria that have been isolated from a variety of environments, including lake sediment (17), soil (26) and pond water (38).…”

“…Within the Proteobacteria, Gammaproteobacteria and Betaproteobacteria were the most abundant groups in natural forest soils at HWD and NCP, respectively; in contrast, Alphaproteobacteria was the most dominant group in HSL soils. Differences in soil bacterial communities have been detected when comparing undisturbed forests and pastures established from cleared forest land (22,37). Proportional differences in gammaproteobacterial-affiliated clones were also found between forests with whole-tree harvesting without soil compaction and those with harvesting plus complete surface organic matter removal with heavy soil compaction (4).…”

Forest disturbance often results in changes in soil properties and microbial communities. In the present study, we characterized a soil bacterial community subjected to disturbance using 16S rRNA gene clone libraries. The community was from a disturbed broad-leaved, low mountain forest ecosystem at Huoshaoliao (HSL) located in northern Taiwan. This locality receives more than 4,000 mm annual precipitation, one of the highest precipitations in Taiwan. Based on the Shannon diversity index, Chao1 estimator, richness and rarefaction curve analysis, the bacterial community in HSL forest soils was more diverse than those previously investigated in natural and disturbed forest soils with colder or less humid weather conditions. Analysis of molecular variance also revealed that the bacterial community in disturbed soils significantly differed from natural forest soils. Most of the abundant operational taxonomic units (OTUs) in the disturbed soil community at HSL were less abundant or absent in other soils. The disturbances influenced the composition of bacterial communities in natural and disturbed forests and increased the diversity of the disturbed forest soil community. Furthermore, the warmer and humid weather conditions could also increase community diversity in HSL soils.
