Individuals in a population of small lizards in an area have different coloration. While 80% of the lizard population is a light tan, 20% is a dark reddish-black. A city planner is allowing a new subdivision to be built in the area, but wants to protect the lizard population as much as possible. Which of the following themes for concrete colors should the city planner suggest be used, and why?
a mixture of light tan and reddish-black; this will reduce competition for food between the two varieties
reddish-black; the contrast will allow the majority of the lizards to be seen by residents more easily
a mixture of light tan and reddish-black; every lizard can find camouflage for protection from predators
light tan; to camouflage for the majority of the lizard population and encourage the reddish-black lizards to adapt to the color change

Mice thrive on acorns in New England forests. Deer tick larvae thrive on mice. Every 3-4 years, oak trees in the New England forests product a bumper crop, or overabundance, of acorns. Mice are the primary vector for the bacteria which produces Lyme disease.
