In the scenario described, where the average temperature increases leading to a shorter winter, it's important to consider the adaptive advantages that each rabbit variety might have in the new climate conditions.
- White-furred rabbits are typically better suited for environments with snow and cold weather, as their coloration provides camouflage in snowy environments, helping them avoid predators.
- Brown-furred rabbits, on the other hand, may have an advantage in warmer climates as their fur is less suitable for camouflage in snowy conditions but can be beneficial in a more temperate or warm environment.
Given that the winter is becoming shorter and presumably less harsh, the camouflage advantage of white-furred rabbits may diminish. Thus, the brown-furred rabbits could thrive better in the changing environment.
Based on these considerations, the most likely scenario would be:
The proportion of white-furred rabbits in the population declines.
This outcome suggests that as environmental conditions change, the brown-furred rabbits are more likely to succeed and reproduce, while white-furred rabbits may struggle and decline in numbers.
