Ranking of models estimating abundance of (a) replete and (b) non-replete ticks (n = 259) and (c) lice (n = 307) in raccoons, including non-genetic and genetic terms.

Analyses were conducted separately for each species and category within species. Models included represent the 90% confidence set (∑weight >0.90) used to calculate the model averages. k = number of model parameters, Wi = Akaikés weight, Δi = evidence ratio, log (l) = log-likelihood value.
