Ecological impact of beavers Castor fiber and Castor canadensis and their ability to modify ecosystems
It is suggested that beavers can create important management opportunities in the Holarctic, and this review will help land man- agers determine the likely outcome of beaver activity.
Comeback of the beaver Castor fiber : an overview of old and new conservation problems
The beaver's reconquest of Eurasia: status, population development, and management of a conservation success
Overhunting reduced Eurasian Beaver (Castor fiber) populations to c. 1200 animals, in eight isolated populations, around the end of the 19th century. Protection, natural spread and reintroductions…
Selective foraging on woody plant species by the Eurasian beaver (Castor fiber) in Telemark, Norway
Size selectivity showed similar patterns to previous North American studies, which were also carried out in habitats with predominantly small saplings, which is consistent with the predictions of optimal foraging models that larger prey items are more likely to be favoured with increasing provisioning distance.
Population and distribution of European beavers (Castor fiber)
After being reduced to about 1,200 animals in eight isolated populations by the beginning of the 20th century, European beavers (Castor fiber) have powerfully recovered in both range and population,…

It is argued that the settlement pattern and reproductive history have a lasting impact in the territorial system of beavers due to a combination of the low adult mortality, high dispersal costs, and avoidance of resource depletion.

Invasive North American beaver Castor canadensis in Eurasia: a review of potential consequences and a strategy for eradication
There is a distinct risk that Cc may eventually competitively exclude Cf at all landscape scales, and as no country in Eurasia obviously wants an invasion of Cc, it is advocated that the precautionary principle be adhered to and an attempt to eradicate Cc from Eurasia be seriously considered.

That environmental variation proves significant to a generalist, wide-ranging species, at the slow end of the slow-fast continuum of life histories, has broad implications for population regulation and the evolution oflife histories.
Use of space and movement patterns in monogamous adult Eurasian beavers (Castor fiber)
The results suggest that beavers show reduced sexual dimorphism in space use and movement patterns within adult monogamous pairs.
