Figure S9 : Comparing densities of climate values
between the entire species wintering range and the wintering sample
sites . Plots on the left-hand side indicate densities along temperature
axis (z-scored) and plots on the right-hand side indicate densities
along precipitation axis (z-scored). Climate values were extracted for
each occupied ecoregion as the mean values across the ecoregion. In red:
climate values extracted across the entire wintering range of the
species; in blue: climate values extracted for ecoregions where
wintering samples are located.
