Table 3.
Model comparison results showing top-ranked models (difference in Akaike’s Information Criterion [ΔAIC] <4) for the effects of ancestry, heterozygosity, sex and age class (subadults and prime adults only) on Florida panther survival during 1997–2006. For each model, we present the number of parameters, ΔAIC and the Akaike weight (wi). The full table is presented in Appendix S4 (Supporting Information)
| Model | Parameters | ΔAIC | wi |
|---|---|---|---|
| Sex × Age3a + Ancest2b + Hetc | 5 | 0·00 | 0·244 |
| Sex × Age3 + Ancest2 | 4 | 0·23 | 0·217 |
| Sex × Age3 + Ancest1d | 5 | 1·35 | 0·124 |
| Sex × Age3 + Ancest1 + Het | 6 | 1·98 | 0·090 |
| Sex + Ancest2 + Het | 3 | 2·77 | 0·061 |
| Sex + Ancest2 | 2 | 2·98 | 0·055 |
| Sex × Age3 + Het | 4 | 3·09 | 0·052 |
Age3 differentiates subadult (age 1–2·5 for females and 1–3·5 for males) and prime adult (ages 2·5–10 for females and 3·5–10 for males) panthers.
Ancest2 divides panthers into two ancestry categories: F1 admixed, and other admixed and pre-introgression type combined.
Het refers to individual average heterozygosity.
Ancest1 divides panthers into three ancestry categories: F1 admixed, other admixed and pre-introgression type.
