Table 3. —Candidate models used in known-fate analyses in Program MARK to evaluate hypotheses on survival of fishers at 2 study sites in the Sierra National Forest, California, from March 2007 to March 2013. Predictor variables in Model 1 included sex, site (northern or southern), age3 (juvenile [6–11 months], subadult [12–23 months], adult [≥ 24 months]), and season (season 1 [18 Mar. to 21 Jul.]; season 2 [22 Jul. to 17 Nov.]; season 3 [18 Nov. to 17 Mar.]). Predictor variables in Model 2 included sex, age2 (juvenile + subadults [6–23 months], adult [≥ 24 months]), and site.
