Table 2:

Model selection results comparing anthropogenic, habitat and global linear mixed-effects candidate models considered to explain grizzly bear body condition in Alberta, Canada

Model (i) Candidate model AIC ΔAIC wi r2
Global Anthropogenic model + habitat model 411.6 0.00 0.92 0.44 (0.56)
Habitat Reproductive class + capture date + number of previous captures + habitat net-energy demand + crown closure (variance) + percentage of conifer + percentage of mixed and broadleaf tree cover + percentage of regenerating forest + percentage of shrub and herbaceous landcover + forest age + vegetation productivity + vegetation seasonality 416.7 5.13 0.10 0.37 (0.53)
Anthropogenic Reproductive class + capture date + number of previous captures + habitat net-energy demand + density of forest harvest blocks + density of secondary linear features + roads (distance decay) + well sites (distance decay) + percentage of parks and protected areas 419.9 8.34 0.01 0.34 (0.47)

Abbreviations: AIC, Akaike information criterion; ΔAIC, difference in Akaike information criterion between the most supported model and the given model; the marginal r2 and conditional (r2) for each candidate model; and wi, weight of evidence for the ith model.
