In an ecosystem, the average temperature increases, causing a shorter winter. There are two varieties of rabbits in this area, Whiteford, rabbits, and Brownford rabbits, which is most likely.

The Whiteford rabbits, which are adapted to colder temperatures and have white fur for camouflage in snowy environments, may be at a disadvantage in this warmer environment. Brownford rabbits, which are better adapted to warmer temperatures and can blend in with the brown surroundings, are likely to thrive and have a better chance of survival in the shorter winter conditions. Over time, this change in temperature could lead to a shift in the population dynamics of the two rabbit varieties, with the Brownford rabbits becoming more dominant in the ecosystem.
