Fig. 4. Relative activity and blood meal fraction of mammals across sites with varying relative probabilities of python presence.

Total numbers of blood meals from marsh rabbit (a), gray squirrel (b), Virginia opossum (c), and white-tailed deer (d) are provided in each panel. Colors of points represent high (red), moderate (yellow), or low (blue) estimated python presence, based upon species distribution model output. Gray triangular shading of the plot area indicates host preference (ratio of host use to relative abundance) by Culex cedecei. The relative activity of mammals was quantified through stratified camera trapping. The blood meal fraction was quantified using PCR-based assays to identify the vertebrate source of DNA in blood-engorged female mosquitoes.
