Migratory Herbivorous Waterfowl Track Satellite-Derived Green Wave Index
Figure 5
Box plots showing the development of the green wave index (GWI) at stopover sites.
The range of GWI values is shown for the three flyways (A), and for the three different years (2008–2010) (B). Each box plot shows the median (line within the box), the 25th percentile (lower end of the box), the 75th percentile (upper end of the box), and 10th to 90th percentile (solid lines). The open circles show the outliers. The significant differences in GWI at the stopover sites between the three different flyways and the three different years seen in an ANOVA analysis using a Bonferroni correction are indicated (here p-value = 0.05/3). ***p≤0.001, ns = non-significant.
