Optimal foraging theory holds that animals' foraging behaviors reflect complex trade-offs that vary by species and with dynamic ecological circumstances. One such circumstance is lunar luminosity. Alexander Love and colleagues found this to be negatively associated with foraging by white-throated round-eared bats, but Patricia C. Wright found it to be positively associated with foraging by three-striped night monkeys. This discrepancy is explicable in terms of the monkeys' greater reliance on vision, which means that higher lunar luminosity benefits them more than it benefits the bats.
According to the text, the difference between Love and colleagues' findings and Wright's findings can be attributed to a difference between white-throated round-eared bats and three-striped night monkeys?
The bats rely less on vision than the monkeys do.
A
The bats decrease their foraging activity as lunar luminosity increases, whereas the monkeys increase their foraging activity.
B
The bats are more vulnerable to predators than the monkeys are.
C
The bats inhabit different regions of lunar luminosity than the monkeys do.
D
