Soil bacterial community structure and physicochemical properties in mitigation wetlands created in the Piedmont region of Virginia (USA)

Effects of experimental warming on soil microbial communities in two contrasting subalpine forest ecosystems, eastern Tibetan Plateau, China

“…However, the H PLFA of the plantation soils increased at 0-10 cm and barelychanged at 10-30 cm, whereas E PLFA only increased in the 0-10 cm soil layer under warming conditions. These results did not agree with those of other studies, which found that the increase in microbial diversity corresponded to an increase in microbial biomass (Ahn and Peralta 2009). This may be due do differing soil microbial communities, and the soil microbial community of natural forest was more sensitive than that in the plantation (Zornoza et al 2009).…”

Development of Soil Properties and Nitrogen Cycling in Created Wetlands

“…Bishel-Machung et al (1996) and Shaffer and Ernst (1999), however, found no relationship between organic matter and time 3-5 or 6 years after creation, respectively, and Ballentine and Schneider (2009) found no significant increases in soil organic matter until 35 years after creation. The lack of organic carbon (C) accumulation, in particular, has been found to be characteristic in many created wetlands under 10 years old (Whittecar and Daniels 1999;Stolt et al 2000;Hossler and Bouchard 2010), which has implications for vegetation development (Stauffer and Brooks 1997), microbial communities (Duncan and Groffman 1994;Ahn and Peralta 2009), and C and nitrogen (N) cycling (Bruland et al 2009;Sutton-Grier et al 2009;Kayranli et al 2010). In general, the age-based trajectory for soil development in created and restored wetlands is unclear.…”

“…Among the primary wetland components that are evaluated in mitigation projects, soils are often the least considered indicator of quality in created or restored wetlands (Shaffer and Ernst 1999;Ahn and Peralta 2009), despite their importance for successful ecosystem development. Soil properties such as organic matter can be an excellent indicator of soil quality (Bruland and Richardson 2006) as it is essential for many biogeochemical properties within the soil matrix.…”

PLFA Profiling of Microbial Community Structure Influencing Ecosystem Restoration in Chronosequence Iron Mine Overburden Spoil

“…Higher relative distribution of arbuscular mycorrhizal fungi (2.13%), fungi (2.74%) and microeukaryotes (66.25%) were observed in NF soil, which may be due to allochthonous inputs, root turnover and symbiotic nitrogen fixation contributed to formation of highly localized soil resources characterized by higher level of organic C and N that are believed to support more diverse heterotrophic microbial population. Greater PLFA diversity also concurred with studies on vegetation succession [75][76]. Further, fungi are adapted to degrade lignin and formation of organic matter [61].…”
