Daily combined bird and bat carcass discovery predictions from generalized additive mixed model.
In the top panel, carcass discoveries are per 100 searches and shaded area is the 95% confidence band of the predicted counts. Bottom panel displays the total number of searches summed across all available studies for each day of the year.
Fig 3.
Daily carcass discovery predictions from generalized additive mixed model for all bats and all birds by North American Level II ecoregion.
Carcass discoveries are per 100 searches and y-axis scale may vary among regions. Center line shows the predicted mean and shaded regions show the 95% confidence intervals. Solid grey sections indicate extended periods of no data. Striped sections indicate periods of sparse data. Only significant results are plotted.
