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 structure of the forest. We aimed to test the hypothesis that beaver activity promotes new foraging sites for insectivorous bats. The beaver’s influence can be especially significant on aerial hawkers that prefer moderate structural clutter, like the Pipistrellus species (by creating new canopy gaps), and… 

Abundance and diversity of small mammals in Swedish beaver systems

It has been concluded that beavers are indeed creating habitat conditions that are favourable for small mammal diversity and abundance, especially as far as shrews and mice are concerned.

A Biodiversity Boost From the Eurasian Beaver (Castor fiber) in Germany’s Oldest National Park

Freshwater ecosystems are among the most threatened ecosystems on the planet. Beavers are important engineers in freshwater ecosystems and reintroduction programs have enabled the recovery of beaver

The impacts of beavers Castor spp. on biodiversity and the ecological basis for their reintroduction to Scotland, UK

The mechanisms by which beavers act as ecosystem engineers are investigated, the possible impacts of beavers on the biodiversity of Scotland are discussed, and a widespread positive influence on biodiversity is expected, if beavers are widely reintroduced.

Mammalian activity in the vicinities of beaver dams in the fall-winter season

European beavers, being so called a "keystone species", transform their habitat according to their own needs while also creating favorable living conditions for other animals. The aim of the research

Impact of Beaver Ponds on Stream Temperature and on Solar Radiation Penetration in Water

Restoration of the beaver population (Castor Canadensis) to streams and rivers is desirable because they are a sustainable and lower cost method of improving stream habitat when compared to

Ponds in acidic mountains are more important for bats in providing drinking water than insect prey

It is concluded that ponds in acidic mountain areas are more important to bats as a source of drinking water than as a sources of prey, and that bat conservation strategies should maintain a continuous network of water sources as an important habitat feature.

Is new spread of the European beaver in Pannonian basin an evidence of the species recovery?

Findings in northern Pannonian lowland (Slovakia–Hungary border) are an important evidence of beaver expansion and indicate the possibility of merging the populations of different origin, which could enable gene flow and increase the genetic diversity.

Terrestrial Wildlife in the Post-mined Appalachian Landscape: Status and Opportunities

Coal mining is an anthropogenic stressor that has impacted terrestrial and semi-aquatic wildlife in the Appalachian Plateau since European settlement. Creation of grassland and early-successional

Outsized effect of predation: Wolves alter wetland creation and recolonization by killing ecosystem engineers

This study demonstrates how predators have an outsized effect on ecosystems when they kill ecosystem engineers by killing dispersing beavers.



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.

The general ecology of beavers (Castor spp.), as related to their influence on stream ecosystems and riparian habitats, and the subsequent effects on fish – a review

The practicality and benefits of reintroducing or restoring beaver populations will vary according to location, and should be considered in conjunction with a managementplan to control their densities.

Beaver ponds as habitat of amphibian communities in a central European highland

The historic effects of beavers need to be considered for a proper understanding of patterns of amphibian distribution and habitat requirements in Central European Highlands, and beaver-created landscapes will be of future relevance for conservation of endangered species.

Macrophyte succession in Minnesota beaver ponds

Ponds of intermediate age (11–40 years) had the highest diversity, with both floating-leaved and submersed life forms represented, and Compositional trends were best explained by propagule dispersal traits.

The use by bats of habitat features in mixed farmland in Scotland

ABSTRACT Most previous studies of the use bats make of their foraging areas have been concerned with general habitat preferences rather than with microhabitats. The present study focuses on

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.

Structure and function of a benthic invertebrate stream community as influenced by beaver (Castor canadensis)

The results suggest that current paradigms applied to lotic ecosystems need to be reevaluated to incorporate the influence of beaver upon invertebrate communities.

Evaluation of Herpetofaunal Communities on Upland Streams and Beaver-Impounded Streams in the Upper Piedmont of South Carolina

Abstract Beavers (Castor canadensis) create numerous scattered wetlands in the southeastern United States that alter the composition of aquatic and adjacent terrestrial communities. However, the
