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.

a<p>All models contained the probability of detection function p(W, LW).</p>b<p>Variables subscripted with β/SE absolute values.</p>c<p>Abbreviations: 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.</p>d<p>Models without uninformative variables. Model-averaged parameter estimates for the untransformed coefficients: E, −0.73 (0.46 SE); T, 0.63 (0.44 SE).
