The top 10 model selection results for study areas in interior North America (n = 90) relating grizzly density to variables that were hypothesized to be functionally related to density.

= precipitation, NDVI = normalized differential vegetation index, AET = actual evapotranspiration, H50 = herbaceous and shrub cover >50%, T25 = tree cover >25%, Meat = terrestrial meat in diet, SP = presence of salmon in diet, LHum = log human density, Live = livestock density, Harv = human-caused mortality, Rug = ruggedness. The top-ranked model was excluded from this list, because it contained 2 uninformative variables. Variables are: Prcp
