The geographic range of the light is therefore 16.9 miles. Example 3 The range of a light as printed on a foreign chart is 17 miles. Our results suggest that, by not accounting for adaptation to cold, current models of potential geographic distributions could underestimate the areas at risk of exposure to this species.
