“…Redundancy analysis (RDA) was performed to reveal the factors that influenced the abundance of waterbirds (Gil-Tena et al, 2015; Zhang et al, 2016;Wang et al, 2021). The specific methods were as follows:…”

“…Standardization of assessment indicators During RDA analysis, assessment indicators were considered as explanatory variables. Since explanatory variables did not share the same units, zero-mean normalization was applied using Canoco5.0 for uniformity of input data (Wang et al, 2021). Quantitative indices were standardized by the range method.…”

The diverse habitat of the coastal areas of Guangdong, China, supports important waterbird populations, thereby contributing to the conservation of waterbirds in China and globally. The sensitivity of different waterbirds to environmental driving factors results in differences in habitat selection, which in combination affect waterbird abundance. This study investigated the effects of environmental and human disturbance factors on the abundance of waterbirds based on a survey of waterbirds in coastal areas of Guangdong Province, China. Redundancy analysis (RDA) was mainly used to study the relationships between the abundance of waterbirds and environmental and human factors. The results showed that the areas of mangrove and tidal flats were the main factors driving the abundance of shorebirds and open water waterbirds, whereas the areas of mangrove and water bodies were the main factors driving the abundance of wading birds and waterfowl, respectively. Road length and the areas of construction land were found to have negative effects on the abundance of waterbirds. A waterbird protection and management strategy was proposed based on the results.

“…Waterbirds play a key functional role in ecosystems as predators that maintain the diversity of other organisms and establish functional connectivity between different habitat patches; they are also effective bioindicators of coastal wetland ecosystem health (Green and Elmberg 2014; Li et al 2021). The community composition of waterbirds is affected by environmental factors such as habitat type, area, food resources, and anthropogenic disturbance (Wang et al 2021a; Yang et al 2022). Changes in community composition, especially seasonal variation, have varied effects on the functional diversity of communities (de Arruda Almeida et al 2019).…”

Context The coastal wetlands of the Bohai Sea are an important stopover site for migratory birds along the East Asia-Australasian flyway. Changes in land use and landscape structure of the coastal zone affect waterbird diversity and ecological conservation. Objectives We studied the community diversity and functional diversity of waterbirds in different habitats and seasons along the entire Shandong section of the Bohai Sea, explored the relationship between waterbird abundance and habitat area, and determined the relationship between bird functional eigenvalues and habitat types. Methods From June 2019 to April 2020, the Shandong section of the Bohai Sea was divided into 10 km × 10 km grids; a total of 87 grids were investigated, and four field surveys of waterbird communities were conducted using line transects and sampling points. We calculated the community and functional diversity of waterbirds in different habitats and seasons and analyzed the relationships of waterbird abundances with habitat area, functional traits, and habitat types using canonical correspondence analysis. Results The community diversity and functional diversity of waterbirds were highest in marsh wetlands, and waterbird richness and abundance were higher in natural wetlands than in artificial wetlands. There were significant differences in the diversity index of waterbirds among habitats and seasons. Habitat area was an extrinsic driver of the spatial distribution of different waterbird guilds, and foraging habits and feeding preferences were key intrinsic drivers. Conclusions Protecting waterbirds in this region requires prioritizing the protection of natural wetlands, reducing their exploitation, decreasing habitat fragmentation, and enhancing habitat connectivity.

“…With the intensification of farmland reclamation and increase of chemical pesticides in the Yancheng Coastal Wetland, the habitat environment of migratory birds in farmland plot gradually deteriorates daily [30,31]. Meanwhile, the food in farmland decreases with the increase of pollution, which is difficult to provide sufficient food sources for migratory birds and is not conducive to the migratory birds' foraging and migration [32,33]. Therefore, in order to improve the habitat environment of birds, the ecological restoration should be carried out in these plots to improve the quality of farmland, in which more abundant food and better habitat will be provided for feeding, moving and resting places for migratory birds [34,35].…”

The wetland played a crucial role in producing oxygen and purifying the air, so the conservation projects were essential in response to natural and perceived destruction. The farmland restoration project was utilized to repair the southern buffer zone of Jiangsu Yancheng Wetland National Nature Reserve for Rare Birds on the investigation and analysis of migratory birds, soil fauna and crops. In this paper, the five different crops of colza oil, mustard, Chinese cabbage, wheat, barley were planted in the restoration plots, which was eaten by migratory birds overwinter resulting to the low yield of crops. The species and biomass of soil fauna in non-winter (7 species and 98 soil fauna) were more than that in winter (6 species and 54 soil fauna), and the results of restoration plots was more than that in control. The variety and number of migratory birds had a significant improvement (18 species and 164231 migratory birds), which was owed to different crops and soil fauna. This study found that farmland restoration project could significantly improve the ecological environment of wetland, enrich the biodiversity and attract more migratory birds for inhabit.
