Summary: The effects of nutrient enrichment on the reproductive differences between invasive and native plants were studied. Nutrient enrichment generally reduced the reproduction of native plants but increased that of invasive plants. This study shows that nutrient enrichment can confer the invasive plant a reproductive advantage, demonstrating an overlooked pathway for biological invasions.

Summary: A new deep learning multi-scale residual convolutional neural network (MRCNN) model was developed to identify the distribution of Spartina alterniflora (S. alterniflora) in Jiangsu coastal wetland. This model improved the accuracy of identifying S. alterniflora distribution and showed advantages in spatial characterization. The study found that the distribution of S. alterniflora in Jiangsu has expanded over time, with three stages identified: the growth period, the outbreak period, and the plateau period. The expansion of S. alterniflora mainly occurred parallel and perpendicular to the coastline, with reclamation of tidal flats being the main factor.

Summary: In plant invasion, the litter of Spartina alterniflora has different effects at different stages. The litter stimulates growth on the edge of the community but inhibits growth in the old community. The effect of litter depends on the stem density of invasive plants relative to native plants.

Summary: Within-species genetic diversity is influenced by geography and has cascading effects on biodiversity. This study investigates the genetic structure of the native species Phragmites australis and its invasive competitor Spartina alterniflora. The results show geographical differentiation in genetic structure and an increase in genetic diversity from south to north. The invasive species alters the relationship between the genetic diversity of the native plant and the associated species richness of soil nematodes.

Summary: Aboveground litter inputs from plants play a crucial role in carbon and nutrient fluxes to the soil. This study compared the effects of aboveground litter from native Phragmites australis and exotic Spartina alterniflora on soil nitrification and denitrification, finding species-specific impacts on these processes, particularly more pronounced in the late growth phase. The study also showed that while previous research has highlighted the strong impacts of invasive Spartina alterniflora on nitrogen removal processes, the aboveground litter from this species did not significantly alter nitrification or denitrification, suggesting the presence of other important pathways in these processes.

Summary: While protected areas are successful in rescuing wetlands and shorebird habitats, plant invasions are extensive and undermine the formation of new native marshes. The global invasion of exotic species into protected areas highlights the profound consequences of bioinvasions on conservation.

Summary: Coastal blue carbon ecosystems have promising benefits for climate change mitigation and adaptation. Research shows that mangrove transplantation and Spartina alterniflora invasion have significant effects on the carbon sequestration potential of coastal wetlands. Additionally, plant-derived organic carbon can be exported to the surrounding environment due to rapid sediment turnover.

Summary: This study aimed to improve upon the limitations of the Ppf-CM method by incorporating geometric, texture, and contextual information. A new object-based phenological feature composite method (OPpf-CM) was developed, which involved stacking two images acquired during distinctive phenological periods of Spartina alterniflora, deriving spectrally homogeneous objects, and using various features from these objects as input for a support vector machine classifier to generate a map of S. alterniflora with higher accuracy than the pixel-based method.

Summary: Mangrove forests are productive and threatened ecosystems, with the invasion of Spartina alterniflora posing a serious risk. Through model evaluation, RF, GBM, and GLM were selected to build a high-precision ensemble model. Using species occurrence records and environmental factors, we predicted suitable habitats for mangrove forests and potential invasion habitats for S. alterniflora in southeastern China. Results showed suitable habitats for mangrove forests primarily in Guangdong, Hainan, and the eastern coast of Guangxi, while suitable invasion habitats for S. alterniflora mainly in Zhejiang and Fujian. The study highlights the importance of bioclimate variables and provides insights for conservation and control efforts.

Summary: The study on the invasive grass Spartina alterniflora along the coast of China found that the flowering phenology exhibited a pattern that was influenced by latitude, with plants at different latitudes flowering at different times. The research results suggest a high degree of plasticity in flowering phenology, with variations in factors such as climate and oceanographic variables affecting the timing of flowering. Additionally, the study indicated some selection for earlier flowering at sites with low temperatures and highlighted the importance of environmental conditions in shaping the flowering patterns of the invasive species.

Summary: The study examined the impact of invasive Spartina alterniflora and subsequent reclamation on soil nitrogen composition in coastal wetlands in China. Results showed that the conversion of mudflats to Spartina alterniflora increased total nitrogen content, while subsequent conversion to aquaculture ponds decreased it. The invasion of Spartina alterniflora was a major driver of increased bioavailability of nitrogen in coastal soil, which was partly reversed by the reclamation for aquaculture ponds.

Summary: This study explored the importance of plant species and different habitat conditions to synchrony in plant productivity across coastal marsh habitats in Georgia, USA. Synchrony was highest within a plant species and within a marsh zone, and decreased across species with increasing distance and elevational differences. Abiotic conditions, such as water column temperature and salinity, also showed high synchrony among sites, pointing to the Moran effect as a likely explanation for the findings.

Summary: This study evaluated the efficiency and ecological safety of the herbicide HPME in removing Spartina alterniflora in Laizhou Bay. The results showed that HPME significantly reduced the density and root weight of S. alterniflora without adverse effects on sediment and other biological communities, indicating that it may be an effective and ecologically safe herbicide for the eradication of S. alterniflora.

Summary: This study constructed spatial distribution maps of on-/off-year Moso bamboo forests (MBFs) using Sentinel-2 time series data and a multitemporal bamboo index. A new Moso bamboo on-/off-year differentiation index (MODI) was proposed and found to effectively detect spatial distribution differences between the on- and off-year MBFs in the study regions. The study also identified variations in the spatial distribution of MBFs among different administrative zones and provinces.
