托福口语 Task 4

Today we're going to talk about a fascinating concept in animal behavior called 'temporal partitioning.' This is when different species that compete for the same resources use the same habitat at different times to avoid direct competition. Let me give you two examples. First, consider the African savanna. Lions and wild dogs both hunt antelope in the same area. However, lions are primarily active at night, while wild dogs are mostly active during the early morning and late afternoon. By hunting at different times, they reduce encounters and competition for the same prey. Second, think about certain species of bats in tropical forests. Insect-eating bats and fruit-eating bats share the same forest, but they have different activity peaks. Insectivorous bats are most active at dusk, while frugivorous bats become active later at night. This temporal separation allows both species to exploit the forest resources efficiently without directly competing with each other. So, in summary, temporal partitioning is a key strategy that enables coexistence among species with similar ecological needs.
