Consider a population of snowshoe hares in montana. their fur color changes in response to changes in day length. during the long summer days, they have brown fur, but as the days shorten in the fall, their fur turns white in preparation for winter. then as the days get longer in the spring, their fur turns brown again. their fur coloration acts as camouflage from predators. as climate change brings warmer fall temperatures to montana, colder temperatures with snowfall are coming later in the year, and there may be less snowfall overall. as a result, the hares' fur color may be mismatched to the color of their surroundings, making them more visible to predators. which snowshoe hares would have a reproductive advantage in this changing environment? which snowshoe hares would have a reproductive advantage in this changing environment? hares that change color in response to day length, as the current population does hares with a mutation that prevents them from changing color from brown to white hares with a mutation that causes them to change color in response to temperature rather than day length hares with a mutation that prevents them from changing color from white to brown

The snowshoe hare, whose scientific name is Lepus americanus, is a mammal native from some regions around North America. Its body is covered by a thick skin that allows to store fat to survive when there is less food and keep warm during the colder times of the year, in addition to abundant fur.

As the days get shorter, the hares's fur begins to change to white and when the days start to lengthen, it returns to brown. This generally coincides with the beginning and end of the snowfall seasons. However, due to climate change, snowfalls start later and last less.

That is, the duration of the day is not coinciding with the snowfall seasons due to the globa increase in temperature. This results in periods of time when hares with white fur are exposed in an environment with bare  ground since their white fur contrasts with the brown/green background in which they are found. And because these animals are not aware of the fact that they contrast with their environment; in the presence of a predator, they behave just like when they are camouflaged: instead of running and hiding, they remain immobile and this is fatal for them.

In this context, the best option for the snowshoe hares related to the reproductive advantage in this changing environment is:

In this way, their fur color will tend to coincide more with cold periods of snowfall and hot periods in summer and spring.
