“…This implied that S. alterniflora may provide a more benign habitat for crabs than P. australis. S. alterniflora has 70% greater root biomass than P. australis (Liao et al 2007); therefore, the belowground structure of S. alterniflora would also have effects on the distribution of crabs. Wu (1959) reported that Chiromantes dehaani prefers moist environments.…”

The effects of invasive cordgrass Spartina alterniflora on burrowing crab communities in the salt marshes of the Yangtze River Estuary, China, were studied. Crab abundance, distribution and diets were compared in native Phragmites australis and invasive S. alterniflora stands. Spartinainvaded stands had 42% higher crab density than did native P. australis stands, largely because 2 dominant grapsoid crabs, Helice tientsinensis and Chiromantes dehaani, thrived in S. alterniflora stands. Sediment grain size, water content and vegetation stem height were the main factors correlated with crab distributions. Crab diet analyses revealed that crab stomach fullness was similar in stands of different plant species, indicating that in Spartina-invaded stands crabs can find compatible food quantity as in native plant stands. Both H. tientsinensis and C. dehaani from S. alterniflora stands had significantly higher δ 13 C values than those from P. australis stands, suggesting that the crabs consumed S. alterniflora in the invasive marshes. This non-selective feeding may be driving the success of H. tientsinensis and C. dehaani in invasive Spartina stands.

“…In Bohai Bay, the level of total carbon (TC) in S. alterniflora sediment after the colonization is higher compared with the mudflat (Chai et al, 2014). In summary, exotic S. alterniflora increases the SOC in the local ecosystems by altering the ecophysiological processes, resulting in changes in NPP and litter decomposition, and ultimately the enhancement of carbon stocks in the native ecosystems (Liao et al, 2007).…”

“…1). It has been documented that S. alterniflora has dramatically enhanced the total N stocks in plant tissue and the soil in less than seven years at Jiuduansha Island in the Yangtze Estuary, China (Liao et al 2007). Accelerated decomposition and epiphytic N fixation on the surface of standing dead litter of S. alterniflora were believed to be the major reason for the rapid increase in ecosystem N pools after S. alterniflora invasion (Liao et al 2007;2008a).…”

Invasive alien plants increase both plant N and soil inorganic N pools in many terrestrial ecosystems. This is believed to be the result of altered plant-soil-microbe feedbacks that accelerate N cycling. However, it may also be due to the greater ability of invasive species to uptake lateral N subsidies that can modify ecosystem N dynamics. We conducted manipulative field experiments to determine the impact of smooth cordgrass (Spartina alterniflora) invasion on the N cycling of salt marsh ecosystems in the Yangtze Estuary, China. The results showed that the aboveground plant N and soil inorganic N pools in S. alterniflora marshes, 14.39 and 3.16 g N m(-2), were significantly higher than those in native common reed (Phragmites australis) marshes, 11.61 and 2.29 g N m(-2). These increases after invasion were explained by a significantly higher uptake of dissolved inorganic N (DIN) from tidal subsidies in S. alterniflora marshes (6.59 g N m(-2)) than from those in P. australis marshes (1.61 g N m(-2)), and not by soil organic N mineralization, which was not significantly different between S. alterniflora (6.45 g N m(-2)) and P. australis marshes (6.84 g N m(-2)) during the growing season. Our study indicated that the ecosystem engineering effects of S. alterniflora, which increases the interception of external N input, can be an alternative mechanism that increases plant N and soil inorganic N pools--especially in ecosystems with ample anthropogenic N subsidies, such as the coastal wetlands of China.
