Mangroves are critical in global carbon budget while vulnerable to exotic plant invasion. Spartina alterniflora, one of typical salt marsh plant grows forcefully along the coast of China, has invaded the native mangrove habitats in Zhangjiang Estuary. However, the effects of S. alterniflora invasion on soil carbon gases (CH4 and CO2) emission from mangroves are not fully understood. Accordingly, we conducted a field experiment to investigate the soil CH4 and CO2 emission during growing seasons in 2016 and 2017 at four adjacent wetlands, namely bare mudflat (Mud), Kandelia obovata (KO), Avicennia marina (AM) and S. alterniflora (SA). Potential methane production (PMP), potential methane oxidation (PMO), functional microbial abundance and soil biogeochemical properties were measured simultaneously. Our results indicate that S. alterniflora invasion could dramatically increase soil CH4 emissions mainly due to the enhancement in PMP which facilitated by soil EC, MBC, TOC and mcrA gene abundance. Additionally, S. alterniflora invasion decreases soil CO2 emission. Both heterotrophic microbial respiration (16S rRNA) and methane oxidation (pmoA and ANME-pmoA) are responsible for CO2 emission reduction. Furthermore, S. alterniflora invasion greatly increases GWP by stimulating CH4 emissions. Thus, comparing with mangroves, invasive S. alterniflora significantly (p < 0.001) increases CH4 emission while reduces CO2 emission.

“…The influence of invasive species on the organic matter cycle has been reported previously, but this influence can be positive or negative [34]. Some authors state that this characteristic of invasive species can increase soil moisture and organic carbon [35,36], but our study revealed the opposite trend which was also correlated with studies by Feng et al [9]. Some ecosystems (forest systems especially) worldwide are able to storage carbon in soil that involves numerous components including biomass carbon and soil carbon [37] and every ecosystem stress (pollution, invasive status, etc.)…”

A giant goldenrod plant, Solidago gigantea, native to North America is rapidly spreading in Europe and may have serious impact on ecosystems that inhabit. There is a lack of information about the effects of this species on soil biochemical properties and distribution and activity of microbial community. We analyzed soil physicochemical properties (soil reaction, soil moisture content, organic carbon and total nitrogen content) associated with activity of microbial population (activity of fluorescein diacetate (FDA), beta-glucosidase, urease and phosphatases enzymes) between invaded and adjacent uninvaded control sites in two habitats, forest and grassland, in the lowland of southeast Slovakia during years 2016 and 2017. The results revealed that invasion of S. gigantea significantly altered several soil properties and is associated with different soil properties. Soil acidity increased, organic carbon and moisture content decreased, while total nitrogen content was not significantly affected by invasion. FDA and urease activity were significantly higher in uninvaded sites. In contrast, beta-glucosidase and alkaline phosphatase activity were enhanced by S. gigantea invasion in both ecosystems studied. Acid phosphatase was not affected by the invasion. Our study proved that S. gigantea can influence several soil microbial properties while others remained unaffected, despite its significant impact on basal soil physicochemical properties.

“…Soil microbes regulate the biogeochemical processes in coastal ecosystems, including the nutrient cycling and C flux and the primary production and decomposition of organic matter (Böer et al., ; Dini‐Andreote et al., ; Hu et al., ; Ikenaga, Guevara, Dean, Pisani, & Boyer, ). However, salt marshes are vulnerable to the anthropogenic disturbances (e.g., plant invasion), which are widely believed to significantly alter the soil biochemical characteristics of coastal ecosystems, leading to changes in the microbial community composition and structure (Kourtev, Ehrenfeld, & Häggblom, ; Liao et al., ; Yang et al., , ).…”

Coastal ecosystems are vulnerable to plant invasion and expected sea level rise in China. This study explored the responses of microbial communities and extracellular enzyme activity in the marsh soils of native Phragmites australis and exotic Spartina alterniflora to waterlogging and increasing salinity (to mimic prolonged inundation and saltwater intrusion) based on the determination of phospholipid fatty acids and analysis of enzyme kinetics. The results showed that waterlogging and increased salinity treatments decreased the soil microbial biomass in both P. australis and S. alterniflora soils, with waterlogging exacerbating the negative effects of salinity. Fungi/bacteria ratios decreased under both waterlogging and salinity treatments, whereas actinomycetes/bacteria ratios increased with increasing salinity. The degree of the adverse effects of salinity on plant growth of S. alterniflora and soil microbial biomass was lower than that on P. australis. Generally, waterlogging treatment increased the activity of sucrase, cellulase, urease, and dehydrogenase in S. alterniflora soil. Increased salinity decreased all the assayed extracellular enzyme activity in both P. australis and S. alterniflora soils. The synergistic effects of waterlogging and increased salinity treatments on the enzyme activities in P. australis soil were significant, whereas only the effect on the cellulase activity was significant in S. alterniflora soil. This study indicated a greater ability of the microbial community and extracellular enzyme activity of S. alterniflora soil to adapt to waterlogging and increased salinity compared with those of P. australis soil due to the lower sensitivity of S. alterniflora growth and soil nutrients to stress.
