“…The flooding tides are regular and semi‐diurnal. Based on 31‐year records (1978–2008) at the nearest tidal gauge station (Waigaoqiao, approximately 35 km from the study site), local mean sea level is 2.17 m, and the mean tidal range is 2.48 m with the maximum tidal range of 4.43 m (Yuan et al. 2011).…”

The natural vegetation was dominated by the annual plant Scirpus mariqueter Wang et Tang (Cyperaceae) in the low-mid-parts of intertidal zones and by Phragmites australis in the mid-high-parts.…”

Genotypic diversity enhances invasive ability of Spartina alterniflora

Although genetic diversity is very important for alien species, which have to cope with new environments, little is known about the role that genetic diversity plays in their invasive success. In this study, we set up a manipulation experiment including three levels of genotypic diversity to test whether genotypic diversity can enhance the invasive ability of alien species, in our case the invasive Spartina alterniflora in China, and to infer the underlying mechanisms. There was no significant relationship between genotypic diversity and parameters of performance in the first year; however, from the summer of the second year onwards, genotypic diversity enhanced four of the six parameters of performance. After two growing seasons, there were significant positive relationships between genotypic diversity and maximum spread distance, patch size, shoot number per patch, and aboveground biomass. Moreover, abundance of the native dominant species Scirpus mariqueter was marginally significantly decreased with genotypic diversity of S. alterniflora, suggesting that enhanced invasive ability of S. alterniflora may have depressed the growth of the native species. There was no significant difference in most measures of performance among six genotypes, but we observed a transgressive over performance in four measures in multiple-genotype patches. At the end of the experiment, there were significant nonadditive effects of genotypic diversity according to Monte Carlo permutations, in six-genotype, but not three-genotype plots. Our results indicated that both additive and nonadditive effects played roles in the positive relationship between genetic diversity and invasion success, and nonadditive effects were stronger as duration increased.

“…Invasions due to anthropogenic impacts are also an ecological problem for coastal wetland ecosystem (Gedan et al, 2009). For example, the invasive species Spartina alterniflora occupies large areas of southeast coast of China (Yuan et al, 2011) and Phragmites australis has invaded the east coast of North America. Both invasive species were introduced through human activity.…”

“…Second, the rapid spread of Spartina should be effectively controlled and restored into waterbird-suitable habitats (Scirpus wetlands). Yuan et al (2011) suggested that Spartina could be effectively controlled and eradicated by cutting its above-ground parts at the key stage of growth (i.e., the blooming period in July) combined with water logging at a proper water depth (>50 cm). Third, appropriate management for aquaculture ponds is needed to improve habitat quality for different waterbirds during different migratory seasons.…”

Changes in waterbird populations in relation to changes in their habitat are of great concern in the Chongming Dongtan wetlands, one of the most important stopovers for migrating waterbirds in the East Asian-Australasian Flyway. We analyzed the relationship between the changes in the dominant waterbird populations (Charadriidae, Anatidae, Ardeidae, and Laridae) and the changes in their corresponding habitats from 2000 to 2012. In natural wetlands, the species number of Anatidae was significantly positively correlated with the Scirpus mariqueter (hereafter Scirpus) habitat but significantly negatively correlated with the Phragmites australis (hereafter Phragmites) habitat. The densities of Charadriidae and Laridae were both significantly positively correlated with the deep water habitat but significantly negatively correlated with the Spartina alterniflora (hereafter Spartina) habitat. The density of Charadriidae, however, also exhibited significantly positive correlation with the Scirpus habitat. In the aquaculture ponds, the changes in the density of Anatidae in the winter were significantly negatively correlated with the changes in aquaculture ponds. Other waterbirds only exhibited positive or negative correlation trends with their habitats, which did not reach the statistically significant levels. Consequently, changes in waterbird populations are significantly correlated with changes in natural wetlands and aquaculture ponds in the Chongming Dongtan wetlands. Natural wetlands and aquaculture ponds are important to migratory waterbirds during the peak of migration and wintering. Our results promote the development of wetland management strategies for protecting migratory waterbirds in the coastal area of the Yangtze River.
