It seems inevitable that certain habitats will transform, and the species living in the habitat will need to adapt as a result.
Hypothetically, a rainforest turns into a savannah. To match in, a frog might change its color to a yellow-ish color. This is to make it harder for predators to see it. Additionally, this lighter color would let the frog cool down. Since there will be less food and resources in a savannah, we can assume that the frog would be smaller. The intense heat in a savannah, coupled with not as much shade, can also cause the frog to be smaller. All in all, as certain habitats change, certain species will need to change its traits to adapt.
