“…On‐the‐other‐hand, Xie et al (2017) reported that dehydrogenase, amylase, and acid phosphatase activities increased over a short‐term reclamation time and then decreased after 40‐year reclamation, while urease and alkaline phosphatase activities showed a fluctuating trend. Similarly, microbial biomass carbon (MBC) increased from 54 to 143 mg kg −1 after 1‐year reclamation and then decreased to 108 mg kg −1 in the reclaimed paddy soils (Xu et al, 2020), while MBC in the Dongtai Forest Farm showed a increase tendency in a range from 54 to 507% during a 7 to 62‐year reclamation time in comparison with the tideland soil (Xing et al, 2020). Moreover, previous studies had found a shift of dominant bacterial community during the conversion from mudflat soils to agricultural soils (Hua et al, 2017; Liu, Ding, et al, 2016; Liu, Wang, et al, 2016; Zhang et al, 2019a).…”

Coastal mudflats reclamation activities show a strong influence on soil properties and microbial community activity, which drive soil carbon and nitrogen cycling. Studies have found there is a shift of bacterial community with reclamation time. However, effects of reclamation time on the soil archaeal community are still largely unknown.Here, we determined soil properties and archaeal community in the soil profiles (0-15, 15-30, 30-45 cm) of different reclaimed sites with different reclamation ages (R12: 12-year; R38: 38-year; R68: 68-year; R100: 100-year) in Rudong County, Jiangsu, China. Soil archaeal communities were identified via Illumina high-throughput sequencing. Soil archaeal communities were dominated by two phyla, the Crenarchaeota (82.1-93.3%) and Thermoplasmatota (4.2-17.9%), which are associated with nitrogen cycle (Nitrosopumilaceae, Nitrososphaeraceae, and Nitrosotaleaceae) and organic carbon metabolism (Marine_Group_II), respectively. Ammonia oxidizing archaea showed a divergent response to the reclamation, i.e. Nitrosotaleaceae increased with reclamation time whereas Nitrosopumilaceae showed a decreasing trend. Soil total carbon, total nitrogen, pH, EC, C:N ratio, NO 3 À -N content, soil moisture, depth, and reclamation age determined archaeal community distribution in our reclaimed sites. Our findings suggest that both reclamation time and soil depth significantly shaped the archaeal community composition, and then in turn modulated soil carbon and nitrogen cycling in the reclaimed mudflats.

“…Other Actinobacteria taxa, reported as pioneers in extreme environments, were representative in C soils, e.g. Geodermatophilaceae (Xing et al, 2020) and Cellulomonadaceae after wildfires (Aanderud et al, 2019). Firmicutes phyla reached high relevancy in C soils with special dominancy of family Bacillaceae, whose species have reported the ability to degrade hydrocarbons accumulated during fires (Xiang et al, 2014) and fix nitrogen (Yeager et al, 2005).…”

Coastal reclamation seriously disturbs coastal wetland ecosystems, while its influences on soil microbial communities remain unclear. In this study, we examined the impacts of coastal reclamation on soil microbial communities based on phospholipid fatty acids (PLFA) analysis following the conversion of Phragmites australis wetlands to different land use types. Coastal reclamation enhanced total soil microbial biomass and various species (i.e., gram-positive bacterial, actinomycete, saturated straight-chain, and branched PLFA) following the conversion of P. australis wetland to aquaculture pond, wheat, and oilseed rape fields. In contrast, it greatly decreased total soil microbial biomass and various species following the conversion of P. australis wetland to town construction land. Coastal reclamation reduced fungal:bacterial PLFA, monounsaturated:branched PLFA ratios, whereas increasing gram-positive:gram-negative PLFA ratio following the conversion of P. australis wetland to other land use types. Our study suggested that coastal reclamation shifted soil microbial communities by altering microbial biomass and community composition. These changes were driven primarily by variations in soil nutrient substrates and physiochemical properties. Changes in soil microbial communities following coastal reclamation impacted the decomposition and accumulation of soil carbon and nitrogen, with potential modification of carbon and nitrogen sinks in the ecosystems, with potential feedbacks in response to climate change.
