The species of wild rabbits that are brown would most likely have a harder time adapting than the white rabbits to the new environment.

Explanation: The brown rabbits are going to have a hard time living in the snow mostly because of their color. The brown rabbit is more likely to be able to live in the desert because they can camouflauge with their surroundings (the sand). Therefore, camouflaging in the white snow to escape a predator would be impossible for brown rabbits, since they could easily be spotted. Furthermore, the white rabbits would have a higher chance of survival since they can camouflage easier in the snow.
