Extended Data Fig. 2: Associations between species traits and climate matching trends.
From: Increasing climatic decoupling of bird abundances and distributions
Relationships between the temporal trend in climate matching and the species’ Hand-Wing Index (a; Pearson’s correlation r = 0.08, p = 0.42), and migratory status (b; ANOVA F = 1.25, p = 0.29; N = 94, 3, 17 for the ‘directional migratory’, ‘dispersive migratory’ and ‘resident’ categories, respectively), and main habitat preference (c; F = 0.34, p = 0.72; n = 42, 43, 29 species for the ‘dense’, ‘semi-open’ and ‘open’ categories, respectively). The box widths represent the interquartile range (IQR), the median is shown as a vertical thick line within each box and the whiskers extend to the largest (upper) and smallest (lower) value no further than 1.5 × IQR. Data beyond the end of the whiskers are represented by dots.
