“…The highest carbon content in a S. alterniflora community was observed at 40-60 cm depth, owing to the below ground biomass in Jiuduansha Island [9]. However, only the top 10 cm of soil, the organic carbon content of the mudflat was significantly increased due to invasive Spartina in mangrove ecosystems in Zhangjiang Estuary [10]. The effect of invasive species on native ecosystems can be influenced by vegetation biomass, litter production, and quality and microbiological activities [12,13,18,19].…”

“…The soil organic carbon is mainly derived from autocthonous carbon sources [8], such as tree litter and root decomposition [4,6]. Therefore, a vegetation composition shift would greatly affect the quality and quantity of plant material input to the soil and change the soil organic carbon pool and dynamics [9][10][11][12][13].…”

“…Spartina alterniflora Loisel., which is native to the eastern coast of North America, has invaded most of the mudflat areas that surround the mangrove forests of southeastern China [10,14,15]. A shift of the vegetation community related to plant invasion or restoration can dramatically change soil organic matter content and its dynamics [9,16,17].…”

“…The primary goal of restoration is to reconstruct ecosystems with similar structure and function to those that were previously degraded or lost [22]. The mangrove vegetation community can be re-established [24,25] and the associated macrofaunal community and trophic relationships can also be gradually restored [10,20,21] after the S. alterniflora is replaced with mangrove species. Short-term restoration of Kandelia obovata Sheue, Liu, and Yong, a mangrove species that is native to southeastern China, did not significantly enhance the soil organic carbon (SOC) stock after 15 years [21].…”

Background and Objectives: The rapid spread of invasive Spartina alterniflora Loisel. in the mangrove ecosystems of China was reduced using Sonneratia apetala Buch.-Ham. as an ecological replacement. Here, we studied the effects of invasion and ecological replacement using S. apetala on soil organic carbon fractions and stock on Qi’ao Island. Materials and Methods: Seven sites, including unvegetated mudflat and S. alterniflora, rehabilitated mangroves with different ages (one, six, and 10 years) and mature native Kandelia obovata Sheue, Liu, and Yong areas were selected in this study. Samples in the top 50 cm of soil were collected and then different fractions of organic carbon, including the total organic carbon (TOC), particulate organic carbon (POC), soil water dissolved carbon (DOC) and microbial biomass carbon (MBC), and the total carbon stock were measured and calculated. Results: The growth of S. alterniflora and mangroves significantly increased the soil TOC, POC, and MBC levels when compared to the mudflat. S. alterniflora had the highest soil DOC contents at 0–10 cm and 20–30 cm and the one-year restored mangroves had the highest MBC content. S. alterniflora and mangroves both had higher soil total carbon pools than the mudflat. Conclusions: The invasive S. alterniflora and young S. apetala forests had significantly lower soil TOC and POC contents and total organic carbon than the mature K. obovata on Qi’ao Island. These results indicate that ecological replacement methods can enhance long term carbon storage in Spartina-invaded ecosystems and native mangrove species are recommended.

Vegetated coastal ecosystems along the Red Sea and Arabian Gulf coasts of Saudi Arabia thrive in an extremely arid and oligotrophic environment, with high seawater temperatures and salinity. Mangrove, seagrass and saltmarsh ecosystems have been shown to act as efficient sinks of sediment organic carbon, earning these vegetated ecosystems the moniker 'blue carbon' ecosystems. However, their role as nitrogen and phosphorus (N and P) sinks remains poorly understood. In this study, we examine the capacity of blue carbon ecosystems to trap and store nitrogen and phosphorous in their sediments in the central Red Sea and Arabian Gulf. We estimated the N and P stocks (in 0.2 m thicksediments) and accumulation rates (for the last century based on 210 Pb and for the last millennia based on 14 C) in mangrove, seagrass and saltmarsh sediments from eight locations along the coast of Saudi Arabia (81 cores in total). The N and P stocks contained in the top 20 cm sediments ranged from 61 g N m −2 in Red Sea seagrass to 265 g N m −2 in the Gulf saltmarshes and from 70 g P m −2 in Red Sea seagrass meadows and mangroves to 58 g P m −2 in the Gulf saltmarshes. The short-term N and P accumulation rates ranged from 0.09 mg N cm −2 yr −1 in Red Sea seagrass to 0.38 mg N cm −2 yr −1 in Gulf mangrove, and from 0.027 mg P cm −2 yr −1 in the Gulf seagrass to 0.092 mg P cm −2 yr −1 in Red Sea mangroves. Short-term N and P accumulation rates were up to 10-fold higher than long-term accumulation rates, highlighting increasing sequestration of N and P over the past century, likely due to anthropogenic activities such as coastal development and wastewater inputs.

Habitat‐specific responses of soil organic matter decomposition to Spartina alterniflora invasion along China's coast

Plant invasions cause a fundamental change in soil organic matter (SOM) turnover. Disentangling the biogeographic patterns and key drivers of SOM decomposition and its temperature sensitivity (Q10) under plant invasion is a prerequisite for making projections of global carbon feedback. We collected soil samples along China's coast across saltmarshes to mangrove ecosystems invaded by the smooth cordgrass (Spartina alterniflora Loisel.). Microcosm experiments were carried out to determine the patterns of SOM decomposition and its thermal response. Soil microbial biomass and communities were also characterized accordingly. SOM decomposition constant dramatically decreased along the mean annual temperature gradient, whereas the cordgrass invasion retarded this change (significantly reduced slope, p < 0.05). The response of Q10 to invasion and the soil microbial quotient peaked at midlatitude saltmarshes, which can be explained by microbial metabolism strategies. Climatic variables showed strong negative controls on the Q10, whereas dissolved carbon fraction exerted a positive influence on its spatial variance. Higher microbial diversity appeared to weaken the temperature‐related response of SOM decomposition, with apparent benefits for carbon sequestration. Inconsistent responses to invasion were exhibited among habitat types, with SOM accumulation in saltmarshes but carbon loss in mangroves, which were explained, at least in part, by the SOM decomposition patterns under invasion. This study elucidates the geographic pattern of SOM decomposition and its temperature sensitivity in coastal ecosystems and underlines the importance of interactions between climate, soil, and microbiota for stabilizing SOM under plant invasion.
