ABSTRACT Wetland ecosystems are facing alarming rates of destruction and degradation, posing significant challenges for avian populations reliant on these habitats. Bird health is closely linked to the composition their intestinal microbiota, which primarily influenced by local conditions, through diet. Building our previous work identifying dietary variations among bird in marshes within a Ramsar site along Somme Avre rivers (France), this pilot study aimed assess relevance using fecal samples collected from ground characterize microbiota via 16S rRNA metabarcoding. We hypothesized that noninvasive sampling method would capture how traits environmental factors shape composition. Sampling was conducted during breeding season at seven locations (six one its outskirts) spanning rural or peri‐urban environments. A total 52 nine species families, predominantly waterbirds, were analyzed bacterial At phylum level, Firmicutes Proteobacteria predominant, with relative abundance genera such as Clostridium , Rothia Bacillus Caldilinea Pseudomonas varying species. The potential enteropathogen Campylobacter detected sites. Multivariate analyses revealed associated trophic guild, ecology, body length, pond surface habitat location. Additionally, weak correlation observed between host phylogeny Although limited sample size, particularly some species, constrains robustness findings, trends align ecological expectations. This highlights opportunistically low‐impact tool exploring relationship gut habitat.

The composition of gut microbiota (and its dynamic) strongly influences the host organism's health, and has been reported to be influenced by a variety intrinsic extrinsic factors in wild birds. However, most studies were carried out on single geographical scale. A study incorporating comparison multiple geographic scales should further improve our understanding contributing for avian microbiota. In this study, we compared composition, diversity function among seven sub-divided populations black-necked crane (Grus nigricollis) wintering Caohai wetland, China. Sequences V3-V4 region 16 S rRNA analyzed those birds from same breeding area, but distant area Dashanbao wetland. We observed divergences both within wetland between two wetlands. Interestingly, wetlands much more pronounced than suggesting determining effect external species.

Mallards (Anas platyrhynchos) are currently one of the most popular species in rare bird breeding several southern provinces China, but there have been no studies comparing gut microbial communities domestic and wild mallards. In this study, 16S rRNA gene high-throughput sequencing technology was used to compare composition diversity Alpha analysis showed significant differences between two groups mallards, richness were significantly higher mallards than Beta that stool samples mostly separated on principal coordinate (PCoA) plot. Firmicutes (68.0% ± 26.5%) abundant bacterial phylum, followed by Proteobacteria (24.5% 22.9%), Bacteroidetes (3.1% 3.2%), Fusobacteria (2.2% 5.9%), Actinobacteria (1.1% 1.8%). The dominant phyla (79.0% 10.2%), (12.9% 9.5%), (3.4% 2.5%), (2.8% 2.4%).

Vertebrates and their gut bacteria interact in complex mutually beneficial ways. The intestinal microbial composition is influenced by several external influences. In addition to food, the abiotic elements of environment, such as temperature, humidity, seasonal fluctuation are also important determinants. Fecal samples were collected from two captive duck species, Baikal teal (Sibirionetta formosa) common (Anas crecca) across four seasons (summer, autumn, winter, spring). These ducks consistently fed same diet throughout entire experiment. High throughput sequencing (Illumina Mi-seq) was employed analyze V4-V5 region 16sRNA gene. dominant phyla all Proteobacteria Firmicutes. Interestingly, alpha diversity higher winter for both species. NMDS, PCoA, ANOSIM analysis showed distinct clustering bacterial between different seasons, while no significant differences discovered species within season. addition, LefSe demonstrated specific biomarkers with highest number revealed winter. co-occurrence network that during illustrated a more intricate structure greatest nodes edges. However, this study identified ten potentially pathogenic which significantly enhanced abundance summer. Overall, our results season mainly regulated community under instant diet. This provides an new understanding variations wild ducks' structure. information available here may be essential data preventing controlling infections caused waterbirds.
