Fig. 3From: Predicting West Nile virus transmission in North American bird communities using phylogenetic mixed effects models and eBird citizen science dataKeystone species. Bird species whose median estimates for their impact on R0 when they are removed from each community they occupy are greater than a 1.01 (dilution effect, the two species above the plot break in this figure), or less than a 0.99 (amplification effect, the four species below the plot break in this figure) fold change in R0. Intervals show median effects in 95% of the communities that each bird occupiesBack to article page
