Association between avian species diversity and Culex minimum infection rate (MIR). Included are MIRs from each of the eight study sites representing 4 microhabitat types in urban Atlanta, GA, USA, July-September, 2010–2011. a Species diversity at-large: here diversity was calculated considering all observed birds. b Species diversity experienced by the pathogen: here, diversity was calculated considering only species observed previously to have been utilized as a Culex blood-meal host
