Fig. 3.

Predicted nymphal infection prevalence of Borrelia burgdorferi under different larval feeding scenarios on Block Island, RI (varying the quantities p_mice, p_bird, and p_deer). The corners of the ternary plot represent hypothetical scenarios wherein all larvae feed on a single host type (i.e. either exclusively deer, mice, or birds) while the edges of the ternary plot represent scenarios where larvae feed on only two of the three host types; points inside the triangle represent some combination of all three. The white dot (values indicated in black box) indicates the proportions of larvae estimated to have fed on birds, mice and deer to result in the observed nymphal infection prevalence (NIP) of 30%.
