CCA biplots for mosquito species and stages and the environmental factors measured in tires in summer (July–August) 2006 for six sites within central Illinois (n = 65 tires). For each axis, the amount of variation explained as a part of the total variation in the model is shown. Arrows indicate the direction and relative importance of the environmental factors (Detritus category: Fine, Leaf, Seed [including fruit]); Habitat category (Tiresize – Tire size, Cover – Canopy cover, Human – Human density); Microorganism category (ProN – Protozoan abundance, PS – Bacterial productivity via protein synthesis). Species (a – Aedes albopictus, o – Ae. atropalpus, t – Ae. triseriatus, p – Culex pipiens, r – Cx. restuans, s – Cx. salinarius) and stages (E – early instars, L – late instars) are indicated within symbols. For clarity, Aedes are enclosed in squares, and Culex in circles.
