Fig. 6

Contour plots showing the effects of interactions between the relative area of semi-permanent wetland and hydrological conditions (PHDI) on the log odds of an EEEV positive Cs. melanura pool. (a) shows this relationship during the previous fall/winter (10 month lag) and (b) depicts the relationship during the transmission season (0 month lag). Blue represents low log odds of EEEV presence, yellow represents high log odds of EEEV presence, and the value range is listed in the upper right of both plots
