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 Nathan Upham and John Hafner found to be negatively associated with foraging by desert kangaroo rats but Ian C. Colquhoun found to be positively associated with foraging by black lemurs. This discrepancy is explicable in terms of OFT: the lemurs greater reliance on vision means that higher lunar intensity benefits them more than it benefits the kangaroo rats.
Which choice best describes the finding made by Colquhoun, as presented in the text?
As lunar intensity increases, black lemurs increase their foraging activity.
A
Increased lunar intensity is more beneficial for black lemurs than it is for desert kangaroo rats.
B
As lunar intensity increases, desert kangaroo rats reduce their foraging activity.
C
During periods of high lunar intensity, black lemurs increase their reliance on vision.
D
