“…The overall bacterial diversity and composition were comparable with those found in other peatlands (Dedysh et al, 2006;Morales et al, 2006;Ausec et al, 2009;Pankratov et al, 2011;Serkebaeva et al, 2013;Sun et al, 2014).

“…They are known for their ability to degrade cellulose, lignin and other complex biopolymers in different soil habitats (Mccarthy, 1987;le Roes-Hill et al, 2011), which enable them to survive in environments with low C availability (Fierer et al, 2003). The lower relative abundance of Proteobacteria in our study sites compared with previous studies (Ausec et al, 2009;Serkebaeva et al, 2013;Sun et al, 2014) can be explained by the different approach in sequence abundance recalculation per different OTU.

“…These studies found that the most frequent bacteria in peat are the representatives of Proteobacteria and Acidobacteria, which have good adaptations to acidic conditions and exhibit many different lifestyles. There is only one study of the microbial community composition of SSF (Sun et al, 2014), which focused entirely on the surface aerobic layer. The archaeal community has been shown to be dominated by methanogens and their composition varies according to nutrient status and prevailing substrate Juottonen et al, 2005;Metje & Frenzel, 2007).…”

It is not well understood how the ecological status and microbial community composition of spruce swamp forests (SSF) relate to those found in bogs and fens. To clarify this, we investigated biogeochemical parameters and microbial community composition in a bog, a fen and two SSF using high throughput barcoded sequencing of the small ribosomal subunit (SSU) variable region V4. The results demonstrated that the microbial community of SSF is positioned between those of bogs and fens, and this was confirmed by in silico predicted metabolic potentials. This corresponds well with the position of SSF on the trophic gradient and reflects distinct responses of microbial communities to environmental variables. Species richness and microbial diversity increased significantly from bog to fen, with SSF in between, reflecting the variation in pH, nutrient availability and peat decomposability. The archaeal community, dominated by hydrogenotrophic methanogens, was more similar in SSF and the bog compared with the fen. The composition of the bacterial community of SSF was intermediate between those of bog and fen. However, the production of CO2 (an indicator of peat decomposability) did not differ between SSF and bog, suggesting the limiting effect of low pH and poor litter quality on the functioning of the bacterial community in SSF. These results help to clarify the transitional position of SSF between bogs and fens and showed the strong effect of environmental conditions on microbial community composition and functioning.

“…This phenomenon also causes the availability of organic matter to increase. As a consequence, the presence of specific bacteria populations may be favored in the soil [85]. Between 40% and 70% of soil bacteria are associated with stable aggregates (clay particles) [86].…”

Wastewater Reuse in Agriculture: A Review about Its Limitations and Benefits

For centuries, wastewater has been improperly used in agriculture, presenting potential risks to public health and the environment. In the context of scientific development, and confronted by an increasing water crisis, wastewater reuse merits consideration because the practice helps decrease water use pressure and moderates water pollution. Thus, this article presents a literature review that addresses the effects, both positive and negative, of wastewater use in agriculture, emphasizing the effects on the soil environment. The literature review reveals that, until the 1990s, research studies promoted the use of wastewater for irrigation purposes from a treatment approach, while proposing "end of pipe" conventional solutions. However, more recent research studies (2012)(2013)(2014)(2015)(2016) reveal that agricultural reuse significantly affects soil texture properties, while also causing possible alterations of the biomass and microbiota. In addition, research in this period has been oriented to the quantitative evaluation of microbiological risk.

“…The main phyla of bacteria found in boreal forest soils are Proteobacteria, followed by Bacteriodetes, Acidobacteria, Actinobacteria, Firmicutes, Planctomycetes, and Verrucomicrobia (16,17). Environmental factors such as pH, moisture, base cation abundance, as well as the quality of available carbon, all influence soil microbial communities (18)(19)(20)(21).…”

The Athabasca oil sand deposit is one of the largest single oil deposits in the world. Following surface mining, companies are required to restore soil-like profiles that can support the previous land capabilities. The objective of this study was to assess whether the soil prokaryotic alpha diversity (␣-diversity) and ␤-diversity in oil sand soils reconstructed 20 to 30 years previously and planted to one of three vegetation types (coniferous or deciduous trees and grassland) were similar to those found in natural boreal forest soils subject to wildfire disturbance. Prokaryotic ␣-diversity and ␤-diversity were assessed using massively parallel sequencing of 16S rRNA genes. The ␤-diversity, but not the ␣-diversity, differed between reconstructed and natural soils. Bacteria associated with an oligotrophic lifestyle were more abundant in natural forest soils, whereas bacteria associated with a copiotrophic lifestyle were more abundant in reconstructed soils. Ammonia-oxidizing archaea were most abundant in reconstructed soils planted with grasses. Plant species were the main factor influencing ␣-diversity in natural and in reconstructed soils. Nitrogen deposition, pH, and plant species were the main factors influencing the ␤-diversity of the prokaryotic communities in natural and reconstructed soils. The results highlight the importance of nitrogen deposition and aboveground-belowground relationships in shaping soil microbial communities in natural and reconstructed soils. IMPORTANCE Covering over 800 km 2 , land disturbed by the exploitation of the oil sands in Canada has to be restored. Here, we take advantage of the proximity between these reconstructed ecosystems and the boreal forest surrounding the oil sand mining area to study soil microbial community structure and processes in both natural and nonnatural environments. By identifying key characteristics shaping the structure of soil microbial communities, this study improved our understanding of how vegetation, soil characteristics and microbial communities interact and drive soil functions.KEYWORDS biodiversity, boreal forest soil, microbial community, nitrogen deposition, oil sands, plant community, soil restoration, soil microbiology T he Athabasca oil sand deposit, located in the boreal forests of northern Alberta, is part of the largest single oil deposit in the world, with proven reserves of 166 billion barrels of bitumen and covering 142,200 km 2 (1). Most of the bituminous sands (80%) can be extracted using in situ recovery methods (i.e., steam injection wells), but 20% of
