Ohio statewide butterfly population trends of nine resident species with annual variation. Plotted are model predictions for each year based on the fixed effects of year (solid line) and annual random effects (dots) to show annual variation about the trend line. Shading shows 95 percent confidence intervals based on bootstrapped model fits in the poptrend package for the temporal trend and for the annual random effects. The first year’s estimate is set to a value of 1 as a baseline for relative population changes. Graphic: Wepprich, et al., 2019 / PLOS ONE
