Beaver and their associated ponds and wetlands may be overlooked as effective wildfire-fighting tools. [71] Eric Collier's 1959 book, Three Against the Wilderness, provides an early description of a string of beaver ponds serving as a firebreak, saving the home of his pioneer family from a wildfire in interior British Columbia.

Despite being widespread in some beaver-inhabited areas, beaver canals and their environmental effects are much less studied than beaver dams. Beaver primarily develop canals to increase accessibility of river resources, facilitate transport of acquired resources, and to decrease the risk of predation. Beaver canals can be over 0.5 km in length ...
Beaver dam, an animal construction which has a transformative effect on the environment. The beaver is a well known ecosystem engineer and keystone species. It transforms its territory from a stream to a pond or swamp. Beavers affect the environment first altering the edges of riparian areas by cutting down older trees to use for their dams ...
Beavers hold a very specific biological niche in the ecosystem: constructing dams across river systems. Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the active movement of ...
Belaney wrote several books, and was first to professionally film beavers in their environment. In 1931, he moved to a log cabin in Prince Albert National Park, where he was the "caretaker of park animals" and raised a beaver pair and their four offspring. [120]
Beavers have also been shown to maintain habitats in such a way as to protect the rare Saint Francis' satyr butterfly and increase plant diversity. [ 9 ] Biodiversity may also be affected by ecosystem engineer's ability to increase the complexity of processes within an ecosystem, potentially allowing greater species richness and diversity in ...
Bridgewater played nine NFL seasons with six teams before retiring after last season, which he spent with the Lions. He threw for 15,120 yards and 75 touchdowns in 79 career games after being a ...
The mountain beaver (Aplodontia rufa) [Note 1] is a North American rodent.It is the only living member of its genus, Aplodontia, and family, Aplodontiidae. [2] It should not be confused with true North American and Eurasian beavers, to which it is not closely related; [3] the mountain beaver is instead more closely related to squirrels, although its less-efficient renal system was thought to ...
