Table 1:
Variables evaluated as potential determinants of the age class (immature or adult) of 86 male brown bears and 83 female brown bears that were either captured in Alberta, Canada (N = 36) or Sweden (N = 63), or killed legally Sweden (N = 70), between 2000 and 2014
| Attribute | Predictor variable (abbreviation) | Variable type | Values |
|---|---|---|---|
| Hormone | Testosterone (test) | Continuous | 0.2–27.6 pg/mg |
| Progesterone (prog) | Continuous | 0.3–17.4 pg/mg | |
| Estradiol (est) | Continuous | 0.0043–0.0261 pg/mg | |
| Cortisol (cort) | Continuous | 0.33–12.99 pg/mg | |
| Time | Adjusted ordinal daya (d) | Discrete | 1–365 with March 21 set as Day 1 |
| Year (y) | Discrete | 2000–14 | |
| Contact method | Contact method (cm) | Categorical | culvert trap capture, remote drug delivery from helicopter capture or legally killed |
| Study area | Study area (sa) | Categorical | Alberta or Sweden |
aAdjusted ordinal day is the day on which a bear was captured or killed, and sampled. March 21 was set as Day 1 to represent the approximate time that a bear emerged from its den.
