Models within two AIC units of the top model for using changes in occupancy (ψ) to estimate colonization (γ) and abandonment (ε) probabilities of bull trout.

aAll models contained the probability of detection function p(W, LW).
bVariables subscripted with β/SE absolute values.
cAbbreviations: E, elevation; T, temperature; LW, large wood; W, stream width; G, gradient; B, brook trout presence at site; D, distance to where bull trout are common in the main-stem East Fork Bitterroot River; F, occurrence of moderate- to high-severity fire.
dModels without uninformative variables. Model-averaged parameter estimates for the untransformed coefficients: E, −0.73 (0.46 SE); T, 0.63 (0.44 SE).
