“…Further, stochastic (e.g., dispersal by wind, ecological drift) and deterministic processes can interact to influence microbial community composition in soil (Caruso et al, 2011;Cline and Zak, 2014;Ferrenberg et al, 2013;. While soil microbial community assembly in anthropogenically disturbed soils is not widely studied, deterministic factors such as bulk density, pH, and plant species can be influential in shaping communities following physical disturbance of the soil profile (Calderón et al, 2000;da C Jesus et al, 2009;Li et al, 2016).…”

“…To date, there has been some insight into how microbial communities respond to surface mining using chronosequence-based approaches (Banning et al, 2008;Li et al, 2016;Sun et al, 2017). However, the relative influence of stochastic and deterministic factors on microbial communities during succession following surface mining remains unexplored.…”

“…However, the relative influence of stochastic and deterministic factors on microbial communities during succession following surface mining remains unexplored. It has been established that physical disturbances such as mining, tillage, and land use change can cause distinct declines in ecologically important soil physical and chemical parameters (e.g., bulk density, water-holding capacity, pH, C and N content) as well as microbial activity, biomass, and diversity, which is suggestive of deterministic selection (Banning et al, 2008;Calderón et al, 2000;da C Jesus et al, 2009;Li et al, 2016;Sun et al, 2017). Stochastic processes also shape microbial succession following disturbance, for example, through genetic bottlenecks or barriers to dispersal (Schmidt et al, 2014;Sun et al, 2017;Verbruggen et al, 2012).…”

Understanding the successional dynamics governing soil microbial community assembly following disturbance can aid in developing remediation strategies for disturbed land. However, the influences shaping microbial communities during succession following soil disturbance remain only partially understood. One example of a severe disturbance to soil is surface mining for natural resources, which displaces communities and changes the physical and chemical soil environment. These changes may alter community composition through selective pressure on microbial taxa (i.e. deterministic processes). Dispersal and ecological drift may also shape communities following disturbance (i.e. stochastic processes). Here, the relative influence of stochastic and deterministic processes on microbial community succession was investigated using a chronosequence of reclaimed surface mines ranging from 2–32 years post-reclamation. Sequencing of bacterial and fungal ribosomal gene amplicons coupled with a linear modeling approach revealed that following mine reclamation, while bacterial communities are modestly influenced by stochastic factors, the influence of deterministic factors was ∼7 × greater. Fungal communities were influenced only by deterministic factors. Soil organic matter, texture, and pH emerged as the most influential on both bacterial and fungal communities. Our results suggest that management of deterministic soil characteristics over a sufficient time period could increase the microbial diversity and productivity of mine soils.

“…Establishment of a soil microbial community is crucial for newly reclaimed ecosystems to function because soil microbes play a vital role in the acquisition and cycling of nutrients, formation of soil structure, energy flow, plant diversity and productivity in terrestrial ecosystems (Mummey et al, 2002). Soil microbial biomass, diversity, community structure and function have been used to assess the effects of both the vegetation used in reclamation and length of time since reclamation began on the quality of mine soil (Chodak et al, 2009;Li et al, 2016).…”

Summary Assessment of the activity of the soil microbial community is essential to evaluate the success of reclamation. The purpose of this study was to investigate the effect of reclamation on soil physiochemical, biological and microbial community properties. Soil samples were collected from 12 post‐mining sites with different lengths of time since reclamation (2, 3, 5, 6, 7, 9, 11, 16, 19, 21, 23 and 26 years) at Pingshuo surface coal mine, China. Our results indicated soil organic and labile carbon, nitrogen, enzyme activities, microbial functional diversity, bacterial, archaeal and fungal abundances and taxonomic diversity improved with increasing time since reclamation. Soil pH and bulk density declined with increasing time after reclamation. Redundancy analysis revealed the importance of soil pH in microbial metabolic structure and bacterial genetic assemblages, and soil organic carbon in fungal genetic assemblages. The mine soil quality index (MSQI) was positively correlated with time since reclamation, and reclamation could be considered satisfactory at the 19‐year site with an MSQI >0.5. Soil enzyme activities were strongly correlated with microbial abundance. Our overall findings indicated that nutrition, microbial abundance and functional diversity of the soil ecosystem improved after reclamation. Highlights Reclamation improved nutrition, microbial abundance and diversity in soil of a mining site. Soil enzyme activities were correlated more strongly with microbial abundance than diversity. Soil pH and SOC played important roles in bacterial and fungal genetic assemblages, respectively, with reclamation. MSQI would take about 20 years to reach a satisfactory value after reclamation.

“…Previous studies have shown that soil microbial community succession of bacterial, archaeal and, fungal communities were assessed by tag encoded 454 pyrosequencing. At the phylum level, Proteobacteria, Crenarchaeota, and Ascomycota had the highest detected relative abundance within bacteria, archaea, and fungi, respectively (Li et al 2016).…”

Abstract. Sudrajat, Widhayasa B, Rusdiansyah, Susanto D. 2019. Rhizosphere fungal community, soil physicochemical properties, understorey vegetation and their relationship during post-coal mining reclamation in East Kalimantan, Indonesia. Biodiversitas 20: 1953-1962. The objective of this study was to evaluate the composition of fungal community in rhizosphere, understorey vegetation and soil physicochemical properties post-coal mining reclamation. Soil sampling was conducted using a series of reclamation stages plots (undisturbed, disturbed, two, nine, twelves and sixteen years of reclamation) with drill ground at a depth of 0-30 cm. On each plot, five-point drilling was conducted; soil samples were composited; and their physicochemical properties including soil pH, organic carbon, total N, available P, available K, Ca, Mg, Fe, Mn, and S content were analyzed. Rhizosphere microfungi were isolated by using serial dilution and plated on potato dextrose agar added with Streptomycin. Identification and characterization of soil microfungi were done with the help of accessible manuals of fungi. The results showed that fungal genera at rhizosphere during post-coal mining reclamation were Aspergillus, Penicillium, Cephalosporium, Gliocladium, Humicola, Trichoderma, and Paecilomyces. Aspergillus was dominant comprising 74% of the total isolates. The fungal density in the undisturbed soil and the post-coal mining reclamation soil were higher than in the disturbed soil. The fungal rhizosphere groups isolated were saprophytic fungi that were present in a high relative density. In addition, the results showed that fungal rhizosphere was negatively correlated with soil pH and organic carbon. On the other hand, fungal rhizosphere was positively correlated with total N, available P, and available K. It can be concluded that the time period of post-coal mining reclamation, vegetation, and soil physicochemical profoundly determined the soil fungal community.
