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
