Extended Data Fig. 4: Residuals from the winter submodel describing variation in the area occupied by monarch butterflies.
From: Changes in climate drive recent monarch butterfly dynamics
Estimated residuals (posterior medians) from the winter submodel describing the area occupied by monarchs in each of the overwintering supercolonies, when monarchs were present in early winter, 2004–2018. Solid grey line and shaded area represent a linear trend with 95% credible interval (slope= –0.003, 95% CI = –0.014, 0.008).
