Ecologist Dr. Kenji Sato studied the behavior of Eastern gray squirrels (*Sciurus carolinensis*) in different environments. Sato hypothesized that squirrels living in urban parks with high human foot traffic exhibit a shorter flight initiation distance—the distance at which an animal begins to run away when approached by a human—than squirrels living in quiet, rural forests. Which finding from the study, if true, would most directly support Sato's hypothesis?
- ASquirrels in urban parks consumed a wider variety of human-provided foods, such as bread crumbs and peanuts, compared to squirrels in rural forests.
- BSquirrels in rural forests allowed researchers to approach within an average of meters before fleeing, whereas squirrels in urban parks fled when researchers were an average of meters away.
- Squirrels in urban parks allowed researchers to approach within an average of meters before fleeing, whereas squirrels in rural forests fled when researchers were an average of meters away.Cevap
- DSquirrels in urban parks have developed higher intelligence and better spatial memory to navigate city traffic and avoid predators.
Cevap
The finding that squirrels in urban parks allowed researchers to approach within an average of meters before fleeing, whereas squirrels in rural forests fled when researchers were an average of meters away.
The correct answer directly supports the hypothesis by providing data showing that squirrels in urban areas allowed humans to get closer ( meters) than squirrels in rural areas did ( meters) before fleeing, which means they have a shorter flight initiation distance.
