托福口语 Task 4

Today we're going to talk about a fascinating concept in animal behavior called 'temporal partitioning.' Simply put, temporal partitioning is when different species that compete for the same resources reduce competition by using those resources at different times. This allows them to coexist in the same habitat. Let me give you two examples. First, consider two species of hawks that live in the same forest and both feed on small rodents. One species, the red-tailed hawk, hunts during the day. The other, the great horned owl, hunts at night. Because they hunt at different times, they don't directly compete for the same prey at the same moment. Second, think about two types of bats in a tropical cave. Both eat insects, but one species emerges from the cave to feed in the early evening, while the other feeds just before dawn. This staggering of feeding times means that each bat species has access to insects when the other is not foraging. So, as you can see, temporal partitioning is a key strategy that enables species to share limited resources without constant conflict.
