Extended Data Fig. 8. Biplots of the correlation of environmental and physiological variables on the MDS axes in Fig. 2.

a, Environmental variables derived from Terraclimate. b, Environmental variables measured at time of collection. Correlations were assessed with the envfit() function in vegan, and vector length corresponds to strength of correlation. Long-term climate variables (a) are better predictors of microbiome composition than are more temporary weather and physiological variables measured at the time of collection (b).
