On a quiet spring morning, a resounding “Slap!” reverberates through the air above a remote stream leading to Lake Yellowstone. Over much of the past century, it has been a rarely heard noise in the soundscape that is Yellowstone National Park, but today is growing more common-the sound of a beaver slapping its tail on the water as a warning to other beavers.
When the grey wolf was reintroduced into the Greater Yellowstone Ecosystem in 1995, there was only one beaver colony in the park, said Doug Smith, a wildlife biologist in charge of the Yellowstone Wolf Project.
Today, the park is home to nine beaver colonies, with the promise of more to come, as the reintroduction of wolves continues to astonish biologists with a ripple of direct and indirect consequences throughout the ecosystem.
A flourishing beaver population is just one of those consequences, said Smith.

Based on the rental cost of the computer and the increase in the rent the next day, the rate of change was 37.5%.
<h3 /><h3>How to find the rate of change?</h3>
The rate of change simply refers to how the price of the rent of the computer had changed from the day that James rented it, to the next day.
The rate of change can be found by the formula:
= (New rental cost of computer - Rental cost to James) / Rental cost to James x 100%
Solving for the rate of change gives:
= (55 - 40) / 40 x 100%
= 15 / 40 x 100%
= 37.5%
