Beaver dam adaptive aquatic ecosystem blocking river flow
Beavers are very adaptive to the aquatic ecosystem where they dam water by Mocking the river flow to live in the pooled water. They are famous for this specialty and are known as one of the best builders in the animal kingdom.
With the help of sharp incisors, they destroy trees and gather branches to stake them up as a barrier in a flowing river where water pools and they build their lodge to live there.
By blocking the river flow with twigs, branches, grasses and leaves interwoven in mud and stones, they make sure the dam is strong enough not to be washed away easily by the pressure of the water. Their cleverness can be judged from the fact that in slow moving water, they build straight dams while in fast moving water the dam is curved in shape.
