The Eurasian and North American beavers aresimilar in their ecological requirements, andrequire water deep enough to cover the entranceto their lodge or burrow. A food cache isoften built next to the lodge or burrow, exceptin some southern areas. On small streams (upto fourth order) dams are frequently built tocreate an impoundment, generally on lowgradient streams, although at high populationdensities dams may be built on steeper gradientstreams. On large rivers or in lakes, simply alodge with… 
Beaver impact on stream fish life histories: the role of landscape and local attributes
The Eurasian beaver (Castor fiber) has been reintroduced into the Carpathian Mountains and has once again become an important factor for modifying streams. Forty-three sampling sites were compared
Beaver dams, streamflow complexity, and the distribution of a rare minnow, Lepidomeda copei
Freshwater fishes are threatened globally, and often too little is known about threatened species to effectively guide their conservation. Habitat complexity is linked to fish species diversity and
North American Beaver (Castor canadensis Kuhl) Key Habitat Characteristics: Review of the Relative Effects of Geomorphology, Food Availability and Anthropogenic Infrastructure
ABSTRACT The North American beaver is considered a keystone species because its behaviour leads to profound changes in the wetland systems within forested landscapes. Such changes influence species
Reintroduction of beavers may improve habitat quality for vespertilionid bats foraging in small river valleys
Beavers strongly modify their environment by not only building dams and creating ponds, which slow the water flow, but also by selective cutting and removing of trees, which change the spatial
Dam Site and Vegetation Selection by Reintroduced Beaver (Castor canadensis) on the San Pedro Riparian National Conservation Area, Arizona
Beaver (Castor canadensis) were reintroduced on the San Pedro Riparian National Conservation Area (SPRNCA) after having been extirpated. The two most obvious effects from this keystone species, dam
The Role of Complexity in Habitat Use and Selection by Stream Fishes in a Snake River Basin Tributary
AbstractImpacts from grazing, agriculture, and other anthropogenic land uses can decrease stream habitat complexity that is important to stream biota and often is the goal of stream habitat
Reintroduction of beavers Castor fiber may improve habitat quality for vespertilionid bats foraging in small river valleys
TLDR
The hypothesis that beaver activity promotes new foraging sites for insectivorous bats is tested, and the activity of the Myotis species was significantly lower on the transect with the largest beaver ponds, possibly due to the blanket of duckweed, which is known to produce clutter echoes.
Unequal summer use of beaver ponds by river otters : influence of beaver activity, pond size, and vegetation cover
TLDR
Otter activity at beaver ponds was positively associated with beaver presence, pond size, and vegetation cover, and how these pond characteristics can benefit otters in terms of two key habitat needs, availability of prey and shelter is discussed.
Including wildlife habitat in the definition of riparian areas: The beaver (Castor canadensis )a s an umbrella species for riparian obligate animals
TLDR
A review of riparian invertebrates, amphibians, reptiles, mammals, and birds indicates that a 50 m-wide riparian buffer is the mini- mum area for supporting the majority of riparians obligate species, and that riparian buffers be continuous and integrated in a connectivity plan including upland re- serves.
River management and habitat characteristics of three sympatric aquatic rodents: common muskrat, coypu and European beaver
TLDR
The ecological environment of three aquatic rodents was studied in the French Ardennes region to compare the ecological requirements of these three species and predict their future range distributions, and to suggest appropriate management according to each species’ status.

Beaver (Castor canadensis) alter the structure and dynamics of aquatic ecosystems with a minimum of direct energy or nutrient transfer. Through dam building and feeding activities, beaver act as a

The primary purpose of this study has been to analyze and interpret patterns of use of varyinig supplies of willow and aspen at 3 beaver colonies in the northern Sierra Nevada.
Simulated effects of the beaver on vegetation, invertebrates and ducks
TLDR
The study suggests that the beaver can act as a keystone species by affecting the structure of riparian communities and the waterfowl can take advantage of these changes.
Structure and function of a benthic invertebrate stream community as influenced by beaver (Castor canadensis)
TLDR
The results suggest that current paradigms applied to lotic ecosystems need to be reevaluated to incorporate the influence of beaver upon invertebrate communities.
The Effect of a Beaver Dam on the Insect Fauna of a Trout Stream
TLDR
The number of insects emerging immediately decreased as species dependent on a lotic environment were destroyed or forced to migrate and a few species were able to tolerate the new ecological conditions.

TLDR
The population dynamics and feeding ecology of pumpkinseeds inhabiting two isolated Ontario beaver ponds and adjacent Lake Opinicon were examined to determine the persistence of and reasons for small body size in pond populations.
