Response curves for environmental variables with the top 3 variable importance, provided by the best habitat model of each mammal species, in the snowfall regions of northern Japan. The contribution ratios of these three variables to the total value of variable importance extracted from all the variables was 88.7% for boars, 53.2% for foxes, 70.8% for hares, 80.8% for macaques, 69.4% for martens, 73.6% for raccoon dogs, and 55.1% for serows
