Spatial distribution of 115 time series (80 populations from 18 known rodent species, 35 mixed populations from unknown species) of rodents in China and the changing trend of 18 rodent species. The pies in the map show the sites of the 115 time series, the size of the pies indicate the number of time series, and the size of slices of each pie indicate the proportion of increase (red), decrease (blue), and no trend (green) time series. The surrounding panels around the map show the changing trend of normalized rodent abundance of the 18 rodent species and the mixed populations. The color of symbols or lines indicates the changing trend of the time series: increase (red), decrease (blue), and no trend (green). The dashed gray lines of each panel indicate the rodent abundance of each species from multiple sites
