Summary: Understanding the dynamics of avian gut fungal communities and potential pathogens across different seasons is crucial for assessing their health and ecological interactions. This study found significant differences in fungal diversity and community composition between summer and autumn in captive Baikal teal and common teal. The study also identified animal pathogens and saprotrophs in the gut fungal communities, with seasonal variation influencing their diversity and abundance. The results highlight the importance of considering seasonal dynamics and potential pathogens in captive duck gut microbiota.

Summary: The study focused on the seasonal cycling of mercury and methylmercury in vegetated sediments in the Dongtan wetlands of the Yangtze River Estuary, as well as the potential health risk of mercury in estuarine wetlands. The results revealed significant differences in the seasonal variations of total mercury and methylmercury, with the activity of methylating bacteria identified as a major contributor to elevated methylmercury levels. It was also found that the addition of mercury greatly increased the production of methylmercury, even under suboxic conditions, indicating a long-term health risk in the wetlands.

Summary: This study investigated the morphological features of the intestine of Eurasian common moorhen using scanning electron microscopy and histological analysis. The study found that the intestinal villi varied in shape along the intestinal tract, and were lined by simple columnar epithelium. The muscle layer composition also differed among different parts of the intestine.

Summary: In this study, the accumulation of mercury in various ecological systems in the Liaohe estuary was investigated, and food chain construction and heavy metal accumulation analysis were conducted. The results showed that the accumulation of heavy metals increased step by step with the trophic level of consumers.

Summary: Wetlands are of great environmental value as they provide food and habitat for plants and animals. A study conducted in an old growth cypress wetland in the Mississippi Delta found that wetlands are hotspots for mercury (Hg) methylation and demethylation rates, with these rates influenced by temperature and other environmental factors. The study also provides baseline data for assessing the impacts of modifying water flow on Hg methylation and demethylation rates in wetlands.

Summary: This study evaluated the impact of long-term land use and land cover changes on erosion around the Jarahi River and the Shadegan International Wetlands using Landsat satellite imagery. From 1989 to 2017, areas of agricultural land and built-up regions increased while bare lands and wetlands decreased, resulting in increased levels of soil erosion.

Summary: This study investigated mercury methylation in periphytic biofilms in habitats impacted by run-of-river dams, finding positive mercury methylation rates in wetlands and identifying iron-reducing bacteria as the major contributors to this process. The research provides new insights into mercury methylation in river ecosystems affected by run-of-river dams in temperate habitats.

Summary: This study conducted experimental infections using six H5 HPAIVs isolated in Japan and found that the common teal species has a high susceptibility to HPAIV infection, allowing it to disseminate viruses in the environment and potentially influencing HPAI outbreaks in wild birds in Japan.

Summary: The study investigated the concentration of total dissolved mercury (Hg-T) in groundwater in the coastal parts of Urmia aquifer in Iran, identifying geological weathering as a main source of mercury. One sample exceeded the maximum contaminant level recommended by WHO. The distribution of water samples on the Piper diagram indicated Ca-Mg-HCO3 facies predominance, while the positive correlation of Hg-T with various elements suggested geological formations as a significant source of mercury. Water samples in Eh-pH regions showed potential microbial activity related to mercury methylation and mineralization, indicating sulfate reduction processes and limited anaerobic conditions. The study also found some Hg-bearing species in nonequilibrium geochemical conditions and speculated on the role of Fe-bearing minerals in reducing Hg(II) to Hg(0).

Summary: The present study examined the oesophagus and stomach of the Eurasian common moorhen grossly and by SEM for the first time. The oesophagus had distinct features in its cervical and thoracic parts, while the proventriculus had concentric mucosal folds connected by transverse folds. The gizzard had a thick muscularis to aid in grinding food particles.

Summary: Bird species in tidal marshes are facing increasing pressure from sea-level rise. Previous research on this group focused mainly on the breeding season, neglecting the importance of the winter period for adult survival. This study used a double-pass rope-drag technique to estimate the winter abundance of three bird species in Virginia tidal marshes, providing an effective and unbiased sampling method. The results showed that increasing the number of survey rounds can improve the precision of abundance estimates.
