Summary: Some bacterial resistance mechanisms can degrade antibiotics, potentially protecting neighboring susceptible cells. However, the effects of such mechanisms on bacterial communities of more than two species are not well understood. By conducting experiments on multispecies communities, we found that resistance in one species reduced antibiotic inhibition of other species, but the extent of benefit varied among species.

Summary: In this study, the prevalence and characteristics of qnr-positive Escherichia coli in Germany were investigated, revealing broad distribution in different livestock and food matrices and frequent association with other resistance genes, especially cephalosporin determinants. The presence of qnr was also correlated with genes involved in resistance development against quaternary ammonium compounds. Detection of additional point mutations in the chromosomal QRDR region led to higher MIC values against fluoroquinolones in E. coli isolates. These findings are important for the risk assessment of qnr-carrying E. coli from livestock and food.

Summary: This study characterized extended-spectrum cephalosporin-resistant Escherichia coli isolates from broiler farms and found various sequence types and resistance gene/plasmid combinations. The research indicated the potential coexistence of different STs and resistance gene/plasmid combinations on the same farm, as well as the persistence of strains and plasmids on farms. Further investigation is needed to understand the dynamics of strains, plasmids, and resistance genes within specific broiler flocks.

Summary: The study revealed a high prevalence of ESBL-producing E. coli in veal calves, with calves being successively colonized by different clones leading to a decreasing carriage trend. The persistence of a clone in a farm was significantly associated with the number of colonized calves. Despite high diversity, few dominant bla(CTX-M) gene/plasmid/chromosomal backgrounds were identified, with the spread scenario depending on the farm. Interactions between resistance genes, plasmids, and bacterial clones contribute to fitness optimization in specific environments.

Summary: This study investigated the relationship between the body condition of lekking Great Snipe males and the water level of the river flowing through their breeding grounds. The water level affected soil characteristics and prey availability, which in turn influenced the body condition of the males. An increase in water level improved prey availability but further rise and flooding had negative effects on feeding conditions and accessibility of the floodplain.

Summary: River development and dam construction can have detrimental effects on migratory shorebirds' stopover sites by altering the nutrient and biogeochemical cycles and food chain in riverine ecosystems. This study found that regulated stretches of the Vistula River offered lower abundance of potential prey for migrating shorebirds, leading to longer foraging times and more aggressive interactions among individuals. However, these effects were primarily observed in juvenile plovers migrating for the first time.

Summary: Our review of the literature found that the decrease in Hg emissions and its deposition in the southern Baltic Sea has led to a decrease in Hg levels in water and marine life. However, in recent years, there has been an increase in Hg concentrations in fish, indicating a divergence from the previous trend. This suggests that increasing anthropogenic pressures and changes in the food web can undermine efforts to reduce Hg pollution and human exposure from fish.

Summary: An experimental group of one-day-old commercial hatchery chickens were given a defined mixture of 7 gut anaerobes. The next day, the chickens were inoculated with a ciprofloxacin-resistant APEC O78:H4-ST117 strain, alongside a control group, and monitored for 4 weeks for colonization with the inoculated strains and ciprofloxacin-resistant E. coli. The results showed a significant reduction in colonization rates of ciprofloxacin-resistant E. coli in the experimental group during the first 2 weeks. This suggests that colonization of chickens with defined anaerobic mixtures provides decisive protection during the critical period of intestinal microflora development.

Summary: In Mallard ducks, the sex ratio in wintering flocks is influenced by the winter harshness. This study found that in severe weather conditions, there were fewer males among wintering Mallards in urban waterbodies. Females, despite their smaller size, were able to find favorable conditions in the urban area due to milder climate and supplementary feeding by humans.

Summary: In this study, the abundance of potential prey and foraging habitat preferences of Ringed and Little Ringed plovers in regulated and unregulated stretches of the Vistula River were compared. The larger Ringed Plover primarily foraged on three abundant prey species in invertebrate abundant habitats, while the smaller Little Ringed Plover expanded its diet to include invertebrate species of low abundance and in suboptimal habitats. River regulation resulted in lower prey abundance and increased competition for food resources, influencing the diet diversity and foraging habitat preferences of the smaller plover species.

Summary: In monomorphic species like the Black-headed Gull, both sexes have similar breeding plumage. This study used the Underhill-Zucchini moult model and extensive data to document the development of breeding plumage by age and sex. Adult gulls started head moult in January and nuptial moult at the end of February, while immature gulls started head moult in April and often did not complete moult until the end of May. Males moulted earlier and longer than females, but both sexes completed moult at the same time.

Summary: Urbanization and industrialization have resulted in high levels of heavy metal pollution around the world, posing a threat to ecosystems. In this study, the concentrations of arsenic, cadmium, copper, and lead were analyzed in eggshells of Common Cranes nesting in north-eastern Germany. The results showed that only copper and lead were present in the eggshell samples, and their concentrations were not considered toxic to birds. The study also found a significant decrease in trace element concentrations over the study period. While the ban of leaded gasoline and restrictions on heavy metal-based biocontrol products have contributed to this decrease, increasing agricultural areas have led to a gradual increase in copper levels. Additionally, the study revealed that heavy metals do not accumulate in the circulatory systems of adult cranes over time. This study is the first to assess heavy metal contamination in Common Cranes and highlights the potential of crane's eggshells as a bioindicator for monitoring environmental pollution.
