Fig. 2From: Predicting West Nile virus transmission in North American bird communities using phylogenetic mixed effects models and eBird citizen science dataSpatio-temporal GAM model parameter estimates. Y-axes in panels a–c and the gradient in panel d show the additive effect of centered covariates on R0. The gradient in panel d shows variation in R0 among ecoregions explained by variation in bird communities. Dashed lines show 95% CIBack to article page
