Dams built by beavers help in the growth of brown trout in Chile’s remote Tierra del Fuego, which is also the southern tip of South America, a study found.
The beaver is a large, primarily nocturnal, semiaquatic rodent.
They are the second-largest rodent in the world after the capybara.
Beavers are known for building dams, canals, and lodges.
Their colonies create one or more dams to provide still, deep water to protect against predators, and to float food and building material.
When sites are available, beavers burrow in the banks of rivers and lakes. But they also transform less suitable habitats by building dams.
