Comparison of Huggins models.

The four best fitting models are shown (M1–M4), with model 1 having the lowest AICc value and thus the best fit. Dev describes the fit of the model, k is the number of parameters and wi refers to the weighting factor. A dash indicates whether a model included a term for differentiating probability of detection depending on patch state (flowering vs. nonflowering), patch size (number of stems), patch distance (dist; near or far from observer), site (burned vs. unburned), and observer (obs; individuals A–E). Interaction terms are noted.
