“…It is of significant importance to prevent the spread of infectious diseases in wild birds by studying the gut microbial composition ( Zhao et al, 2018 ). The Yellow River National Wetland in Baotou is an important foraging location, which is a crossroad between the East Asia-Australian and Central Asian flyways, for migratory birds ( Liu et al, 2019 ). A large number of different wild bird species inhabit this place.…”

Gut microbiota plays a vital role in maintaining the health and immunity of wild birds. However, less is known about the comparison of fecal microbiota between different ecological groups of wild birds, particularly in the Yellow River National Wetland in Baotou, China, an important transit point for birds migrating all over the East Asia-Australian and Central Asian flyways. In this study, we characterized the fecal microbiota and potential microbial function in nine bird species of raptors, waders, and waterfowl using 16S rRNA gene amplicon sequencing to reveal the microbiota differences and interaction patterns. The results indicated that there was no significant difference in α-diversity, but a significant difference in β-diversity between the three groups of birds. The fecal bacterial microbiota was dominated by Firmicutes, Proteobacteria, Actinobacteria, and Bacteroidetes in all groups of birds. Furthermore, we identified five bacterial genera that were significantly higher in raptors, five genera that were significantly higher in waders, and two genera that were more abundant in waterfowl. The bacterial co-occurrence network results revealed 15 and 26 key genera in raptors and waterfowls, respectively. The microbial network in waterfowl exhibited a stronger correlation pattern than that in raptors. PICRUSt2 predictions indicated that fecal bacterial function was significantly enriched in the antibiotic biosynthesis pathway in all three groups. Metabolic pathways related to cell motility (bacterial chemotaxis and flagellar assembly) were significantly more abundant in raptors than in waders, whereas waders were enriched in lipid metabolism (synthesis and degradation of ketone bodies and fatty acid biosynthesis). The fecal microbiota in waterfowl harbored more abundant vitamin B6 metabolism, RNA polymerase, and tyrosine and tryptophan biosynthesis. This comparative study revealed the microbial community structure, microbial co-occurrence patterns, and potential functions, providing a better understanding of the ecology and conservation of wild birds. Future studies may focus on unraveling metagenomic functions and dynamics along with the migration routine or different seasons by metagenomics or metatranscriptomics.

“…This index is applied for assessing the pollution caused by a metal and indicates to the proportion of the measured concentration of the involved metal and the maximum permissible concentration of that metal in soil [18]. As the index of pollution decreases, the degree of pollution decreases [19]. This index can be computed via the following mathematical expression [20]:…”

A total of 18 surface soil samples were collected from surrounding of industrial district at north Baiji town, and the concentration of seven trace elements (i.e. Cu, Pb, Zn, Ni, As, Cd and Cr) were analyzed. The geo-accumulation index, pollution index, Nemerow pollution index, ecological risk factor and potential ecological risk index were utilized to assess soil contamination by trace elements. The mean values of geo-accumulation index showed that the study area soils are ranged from moderate to heavy contamination by Ni and slight contamination by As, Cd and Cr and uncontaminated by Zn, Pb and Cu. According to categories of pollution index, the surface soil of study area considers strongly polluted by Ni, moderately polluted by Cr and non-polluted by Cu, Zn, As, Pb and Cd. The Nemerow pollution index values of study area showed 11% of sites are slightly polluted, 17% of sites are moderately polluted and 72% of sites are seriously polluted. According to Eco- risk factor for an individual metal, the values showed moderate to considerable ecological risk by Cd, low to moderate ecological risk by Ni and low ecological risk for Cu, Zn, As, Pb and Cr. For Eco-risk index for metals, the results also showed that 27.8% of sites are low potential ecological risk and 72.2% of sites are moderate potential ecological risk

“…The Yellow River National Wetland of Baotou is an important refueling station for migratory birds, because of its location at an important crossroad of the East Asia/Australian and Central Asian flyways [ 10 ]. We studied whooper swans ( Cygnus cygnus ), a migratory species that arrives at the wetland to replenish energy in early February every year.…”

The energy supply of food available at stopover sites plays an important role in the life cycle of migratory birds. The Yellow River National Wetland in Baotou, China, is an essential migration station and a source of energy for migratory birds as it is located at an important intersection between East Asian/Australian and Central Asian flyways. From February to may 2020, we measured diet composition and energy content of whooper swans (Cygnus cygnus) by fecal micro-tissue analysis to understand their use of the stopover site and inform conservation. The following results were obtained: (1) whooper swans mainly fed on nine species of plants belonging to four families, including corn (Zea mays), reeds (Phragmites australis), and Suaeda (Suaeda glauca), which is related to the availability of local crops and abundance of plants. (2) The energy provided by crops to whooper swans was significantly higher than that of the most abundant plants in wetlands. Zea mays was the most consumed crop, and other abundant wetland plants played complementary roles. (3) The daily energy intake of whooper swans was 1393.11 kJ, which was considerably higher than their daily energy consumption. This suggested that the wetlands and the surrounding farmlands provide energy for the whooper swans to continue their migration. In order to protect migratory whooper swans, protection of important refuelling areas such as our study site should be implemented to provide sufficient energy supplies for continuing migration.
