Optimal foraging theory (OFT) holds that animals’ foraging behaviors reflect cost-benefit trade-offs that vary by species and with dynamic ecological circumstances. One such circumstance is lunar intensity, which Joel Brown and colleagues found to be negatively associated with foraging by Arizona pocket mice but Patricia C. Wright found to be positively associated with foraging by three-striped night monkeys. This discrepancy is explicable in terms of OFT: the monkeys’ greater reliance on vision means that higher lunar intensity benefits them more than it benefits the mice.

Which choice best describes the finding made by Wright, as presented in the text?

• A.

  During periods of high lunar intensity, three-striped night monkeys increase their reliance on vision.

• B.

  As lunar intensity increases, Arizona pocket mice reduce their foraging activity.

• C.

  As lunar intensity increases, three-striped night monkeys increase their foraging activity.

• D.

  Increased lunar intensity is more beneficial for three-striped night monkeys than it is for Arizona pocket mice.
