Bird fecal and environmental microbiota and resistome in Gengga Lake. a PCoA of Bray–Curtis distances between resistomes. b PCoA of Bray–Curtis distances between microbiota. c Simpson phylogenetic diversity. d Observed antibiotic resistance proteins. Boxes denote the interquartile (IQR) between the first and third quartiles (25th and 75th percentiles, respectively) and the line inside denotes the median. Whiskers denote the lowest and highest values within 1.5 times and the IQR from the first and third quartiles, respectively. The asterisks on the top indicate *P < 0.05, **P < 0.01, and ***P < 0.001, (Mann–Whitney U test)
