- Change in Rabbit Population 1850-2000 100 90 80 70 60 50 40 30 20 10 white gray white gray 1850 2000 In 1850 there was a large snowshoe rabbit population in Manitoba, Canada. Over the years, the winter coloration (the color of the rabbit's fur) of the surviving rabbit population changed. The graph shows the change in winter coloration of rabbits between 185 to 2000. Based on the data, we could hypothesize that A) the winters are longer in length. B) the snowshoe rabbit has migrated to another area. the amount of snow cover varied over the years.
