Beavers adapt to their biome by engineering the landscape to meet their needs. They do this by constructing dams in streams and rivers, building lodges out of branches and mud, and felling trees for construction material and food.
For the beavers themselves, the dams raise the water level in an area, protecting their lodges from predators. The mud the lodges are made of dries into rock-hard material, which prevents predators such as wolverines and wolves from getting inside and also keeps the lodge warm in severe winter weather. Beavers create the lodge entrances underwater, making it impossible for other animals to enter. The lodges typically have two chambers, one in which to dry off and another to live in. Beavers do not usually build new lodges every season but instead return to the same ones, repairing them year after year.
According the Alaska Department of Fish and Game, beavers are so vital to an ecosystem that when they are taken away, the ecosystem loses its integrity. Their tree felling and dam construction not only provides them with protection and food, but it also benefits other inhabitants of the ecosystem. The ponds provide wetland habitation for animals such as other mammals, fish, birds, amphibians and insects. The dams limit the effects of erosion and sedimentation and provide filtration that cleanses rivers and streams.Learn More
Every animal displays different adaptations to cold weather. Many birds migrate and travel to a warmer place in the fall before the winter sets in. Smaller animals, such as deer mice, ground squirrels, hamsters and skunks, hibernate. Arctic animals, however, take advantage of the long winter to feed and breed.Full Answer >
The acronym, "MEP," stands for "Mechanical, Electrical and Plumbing," a type of engineering which focuses on the disciplines needed to build safe, working structures for human use and occupation. The mechanical aspect focuses on heating, cooling and ventilation, and the electrical aspect focuses on providing power to all outlets and appliances. The plumbing aspect focuses on the delivery of water and the draining of waste water.Full Answer >
Wolves have many adaptations that enable them to survive in their environments, such as unusually large paws, thick fur coats and keen senses. Wolves are also able to adapt to almost any habitat, with the notable exceptions of deserts and tropical rain forests.Full Answer >
The primary way algae adapts to its environment is by varying its pigment to help it absorb sunlight. Most algae can also reproduce both sexually and asexually, increasing their chances of survival.Full Answer >
