“…Kong et al (2019) reported that the alpha diversity of the intertidal microbial eukaryotes significantly correlated with Cd, Cu, and Zn. It has been reported that high concentrations of heavy metals can alter the soil bacterial communities (He et al, 2017;Kasemodel et al, 2019). The proportion of anthropogenic Pb has been reported to increase from 9 to 15% during 2000-2014 on the coast surrounding Dongshan Island (Xu et al, 2017b).…”

Microbial eukaryotes are pivotal components of marine ecosystems. However, compared with the pelagic environments, the diversity distribution and the driving mechanisms of microbial eukaryotes in the marine sediments have rarely been explored. In this study, sediment cores were collected along a transect from inner to outer Dongshan Bay, Southeast China. By combining high throughput sequencing of small-subunit (SSU) rRNA gene with measurements on multiple environmental variables, the genetic diversity, community structure and assembly processes, and environmental shaping factors were investigated. Alveolata (mainly Ciliophora and Dinophyceae), Rhizaria (mainly Cercozoa), and Stramenopiles (mainly Bacillariophyta) were the most dominant groups in terms of both relative sequence abundance and operational taxonomic unit (OTU) richness. Grain size composition of the sediment was the primary factor determining the alpha diversity of microbial eukaryotes followed by sediment depth and heavy metal, including chromium (Cr), zinc (Zn), and plumbum (Pb). Geographic distance and water depth surpassed other environmental factors to be the primary factors shaping the microbial eukaryotic communities. Dispersal limitation was the primary driver of the microbial eukaryotic communities, followed by drift and homogeneous selection. Overall, our study shed new light on the spatial distribution patterns and controlling factors of benthic microbial eukaryotes in a subtropical bay which is subjected to increasing anthropogenic pressure.

“…Thus, the existence of high concentration of metal(loid) level in contaminated soils will influence the microbial communities because of its toxicity ability. There have been reports that metal(loid)s could affect various microbiological vital functions in soil, including growth, morphology, adhesion and biochemical activities, respiration, and nitrogen and phosphorus geochemical cycles, therefore resulting in a reduction in microbial diversity and changes in microbial community structure [ 3 , 15 ]. Based on this, previous researches, by using fingerprint methods, have revealed that metal(loid)s pollution had obvious impacts on soil microbial communities either in a short-term or long-term period [ 16 ].…”

“…Nevertheless, the fingerprint techniques can only provide limited information on microbial communities [ 16 ]. A more comprehensive study on microbial diversity and the abundance of microbes in soil has recently been obtained using high-throughput sequencing methods, i.e., Illumina sequencing of 16S rRNA gene amplicons, due to their access to more information on the phylogenetic compositions of microbial communities in soil [ 3 , 17 ]. For example, some studies have obviously shown that the investigation in microbial diversity via the high-throughput methods is 100 times more in comparison to the traditional culture-dependent techniques [ 15 ].…”

In this study soils at different depths were collected in a Zn smelting site located in Zhuzhou City, China, in order to understand toxic metal(loid)s distribution and microbial community in vertical soil profile at a smelting site. Except Soil properties and metal(loid)s content, the richness and diversity of microbial communities in soil samples were analyzed via high-throughput Illumina sequencing of 16s rRNA gene amplicons. The results showed that the content of As, Pb, Cu, Cd, Zn, and Mn was relatively high in top soil in comparison to subsoil, while the concentration of Cr in subsoil was comparable with that in top soil due to its relative high background value in this soil layer. The bioavailability of Cd, Mn, Zn, and Pb was relative higher than that of As, Cr, and Cu. The diversity of soil microbial communities decreased with increasing depth, which might be ascribed to the decrease in evenness with increase in depth duo to the influence by environmental conditions, such as pH, TK (total potassium), CEC (cation exchange capacity), ORP (oxidation reduction potential), and Bio-Cu (bioavailable copper). The results also found Acidobacteria, Proteobacteria, Firmicutes, and Chloroflexi were dominant phyla in soil samples. At the genus level, Acinetobacter, Pseudomonas, and Gp7 were dominant soil microorganism. Besides, Environmental factors, such as SOM (soil organic matter), pH, Bio-Cu, Bio-Cd (bioavailable cadmium), and Bio-Pb (bioavailable lead), greatly impacted microbial community in surface soil (1–3 m), while ORP, TK, and AN concentration influenced microbial community in the subsoil (4–10 m).

“…The distribution and diversity of fungal families are strongly influenced by heavy metals, in addition to other well-known chemical drivers (i.e., pH, salinity, K, P, and NO2 -) (Kasel et al, 2008;Lauber et al, 2008;Pan et al, 2020). Heavy metals, particularly Cd, not only alter the soil chemistry, but also have detrimental effects on soil microbial communities when present even in small quantities, which could lead to losses in diversity and soil fertility (Bååth & Anderson, 2003;Kasemodel et al, 2019;Lin et al, 2019;Lv et al, 2019). AM fungi are generally sensitive to changes in soil conditions, including pH, heavy metals, and micronutrients, and are considered to be useful bioindicators of soil contamination (Dietterich et al, 2017;Kasemodel et al, 2019;Lin et al, 2019;Oehl et al, 2010;Pan et al, 2020;Vyas & Gupta, 2014).…”

Qatar is largely characterized by a hyper-arid climate and low soil fertility, which combine to create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. Here we present a study on AM fungi communities and their relationship to soil chemical characteristics. We used high-throughput seqeuncing technique for identifying AM fungal diversity and community composition from different habitat types across Qatar. We found 127 AM fungal taxa, of which majority wee members of the family Glomeraceae. In contrast to what was hypothesized, AM fungi were mainly influenced by soil phosphorous and potassium. Chemical soil properties explained 76% of the variation in AM fungi between locations. The lowest AM fungal diversity was observed in barren areas and sand dunes, possibly due to low bioavailability of total nitrogen, while the highest diversity was observed in well-developed grass patches. Present AM fungi in Qatar were not affected by soil and pH; these fungi have likely been exposed to high salinities through their evolutionary history in the region, favoring resistant AM fungi through natural selection. These findings provide baseline information on AM fungal assemblages from the Arabian Peninsula, and thus contribute to better understanding of global patterns of AM fungi and their chemical drivers.
