Beavers returned to the area in 1954 after a long absence since their extirpation by the fur trade in the 19th century. During drought years, where beavers were present, 60% more open water was available than those same areas during previous drought periods when beavers were absent.
Beavers are the prototypical ecosystem engineer because of the effects their dams have on channel flow, geomorphology, and ecology. Kelp are autogenic ecosystem engineers, by building the necessary structure for kelp forests. An ecosystem engineer is any species that creates, significantly modifies, maintains or destroys a habitat.
Beaver dams push water laterally onto flood plains, increasing groundwater and surface water storage. [4] Presence of beavers can improve water quality through sediment trapping in dams, and provide natural flood control. [6] Ponds and canals store water in areas susceptible to drought. [7] Beaver reintroduction causes flooding in areas that ...
Beavers are associated with activity and environmental engineering. If you are “as busy as a beaver,” you are getting things done. These aquatic rodents spend most of their time in the water ...
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
For niche construction to affect evolution it must satisfy three criteria: 1) the organism must significantly modify environmental conditions, 2) these modifications must influence one or more selection pressures on a recipient organism, and 3) there must be an evolutionary response in at least one recipient population caused by the environmental modification.
For years, beavers have been treated as an annoyance for chewing down trees and shrubs and blocking up streams, leading to flooding in neighborhoods and farms. California recently changed its tune ...
Philip discusses the relationship between beavers and humans throughout history with a focus on Indigenous cultures and the American westward expansion. The title, Beaverland , is an allusion to Philip's argument that "Before 1600, all of the continent from west to east, save a few desert sections, had stretched out as one great Beaverland".
