Question

In the deserts of the southwestern United States, the soils are mostly sandy, with occasional large regions of black rock derived from lava flows that occurred 1.7 million years ago. Mice are found in both sandy and rocky areas, and owls are known predators. What might you expect about coat color in these two mouse populations? Explain. How would you use this ecosystem to further test the camouflage hypothesis?

Answer 1

Most of the soil in the southwestern United States' deserts is sandy, however there are occasionally sizable areas of black rock made of lava flows that happened 1.7 million years ago. Both rocky and sandy environments contain mice, and owls are well-known mice hunters.

How would you utilise this environment to expand on the notion of camouflage?

• You may anticipate that mice living on lava rock would be lot darker and those living on sandy soil would be much lighter based on the colours of the mice.
• In actuality, scientists have discovered and predicted that each colour of mouse will be pursued less frequently in its native environment than in another area.
• Hoekstra's experiment may be repeated using coloured models that have been painted to mimic these two varieties of mouse.
• You would need to create controls in a live mouse transplant experiment to eliminate the variable that the transplanted mice introduced in their new environment.

Answer 2

In the deserts of the southwestern United States, the soils are mostly sandy, with occasional large regions of black rock derived from lava flows that occurred 1.7 million years ago. Mice are found in both sandy and rocky areas, and owls are known predators.

What might you expect about coat color in these two mouse populations? Explain.

How would you use this ecosystem to further test the camouflage hypothesis?

Based on the coloration of the mice, you might expect mice that live on sandy soil to be lighter and those that live on lava rock to be much darker. And in fact, scientists have found and predict that each color of mouse would be less hunted in its natural environment than in another environment. You can repeat Hoekstra's experiment with colored models painted to resemble these two types of mice. Or you could try transplanting a portion of each population into its non-native habitat rather than a different habitat. In a live mouse transplant experiment, you would have to make controls to remove the variable introduced by the transplanted mice in new, unfamiliar territory. You could control the transplant process by transplanting some dark mice from one lava rock area to a distant one, and some light mice from one sandy soil area to a distant area.
