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.Continue Reading
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 about Mammals
Common animals in Europe include beavers, gray wolves, roe deer, European starlings and rock pigeons. Many of these animals have similar counterparts in North America that are either native or introduced. Marine animals, such as monk seals, walruses and several species of whales live on or near Europe's coast.Full Answer >
The main predators of beavers are dependant on region but include bears, wolves, wolverines, lynx, fishers, otters, coyotes, foxes, bobcats, owls, minks, alligators, weasels, hawks, dogs, mountain lions and eagles. However, adult beavers are large, good fighters and can escape into water, meaning that the young are most often targeted. The one exception is humans, which go after adult beavers if they consider them a nuisance.Full Answer >
A biome is defined by the interactions of climate, geology, and local flora and fauna. These factors are influenced by geographical location. For example, regions near the equator are often hot, wet and teeming with life, while those far from the equator are typically cold arid and fairly devoid of life.Full Answer >
Terrestrial biomes are major regions in the Earth that share the same climate despite being in different geographical locations. The Earth has six major land biomes: rainforests, deserts, tundras, grasslands, taiga and temperate deciduous forests. Each biome differs in weather, latitude, topography, relative humidity and amount of sunlight. These climatic regions are determined mainly by rainfall and temperature and are distinguished by their predominant plants and animal communities.Full Answer >
