Small mammal assemblage in beaver-modified habitats

The actions of beavers in water bodies within boreal forests seem to have no effect on the small mammal diversity and their numbers at the regional scale but may have positive effect on them at the larger landscape level as beavers are increasing the overall habitat diversity in the landscape.

Beaver creates early successional hotspots for water beetles

Beavers (Castor spp.) are ecosystem engineers that induce local disturbance and ecological succession, which turns terrestrial into aquatic ecosystems and creates habitat heterogeneity in a

Impacts of a Non-indigenous Ecosystem Engineer, the American Beaver (Castor canadensis), in a Biodiversity Hotspot

Non-native species having high per capita impacts in invaded communities are those that modulate resource availability and alter disturbance regimes in ways that are biologically incompatible with

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

Beavers in lakes: a review of their ecosystem impact

The aim of this review is to analyze the literature on the impact of beavers on lakes, summarize their effects, describe consequences for biotic and abiotic components, and highlight unresolved

Temporal Partitioning between Forest-Dwelling Small Rodents in a Mediterranean Deciduous Woodland

Simple Summary Camera-trapping has been widely used to assess activity rhythms and temporal overlap of different medium- and large-sized mammal species sharing the same habitats. Conversely, this

One House is a Home for Many: Temporal Partitioning of Vertebrates on an American Beaver Lodge

Abstract. American beavers (Castor canadensis) are emblematic of diverse and dynamic freshwater ecosystems across North America. Numerous studies have described positive associations between

Beaver-induced spatiotemporal patch dynamics affect landscape-level environmental heterogeneity

Beavers (Castor sp.) are ecosystem engineers that cause significant changes to their physical environment and alter the availability of resources to other species. We studied flood dynamics created

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.

Alternative perspectives of the angling community on Eurasian beaver (Castor fiber) reintroduction in the River Otter Beaver Trial

Eurasian beaver (Castor fiber) reintroduction is taking place in England with potential benefits for flood alleviation and biodiversity; however there is also opposition. One area of controversy



Beaver facilitation in the conservation of boreal anuran communities

Investigation of anuran fauna in ten beaver ponds in Finland shows that beavers offer high-quality habitats for anurans and facilitate the occurrence of moor Frogs, and it is suggested that these ecosystem engineers could be used in ecosystem restoration.

Whole‐community facilitation by beaver: ecosystem engineer increases waterbird diversity

Wetlands are rich in biodiversity, but globally threatened. After a long period of regional extirpation, beavers have recently returned to many European areas and are now restoring wetlands. The

The beaver as an ecosystem engineer facilitates teal breeding

In boreal areas beaver facilitate teal breeding by enhancing both resource abundance and habitat structure, and this study studied the effect of beaver flooding on breeding success of a dabbling duck, the teal.

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.

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.

Bats benefit from beavers: a facilitative link between aquatic and terrestrial food webs

Bat populations are declining in many areas, partly because up to two-thirds of their wetland habitats have been lost, and Favouring the beaver in habitat management is a tool for creating suitable conditions for many other species, such as bats.

Elephants as agents of habitat creation for small vertebrates at the patch scale.

It is shown that, by damaging trees and increasing their structural complexity, browsing elephants create refuges used by a common arboreal lizard, suggesting that anthropogenic changes in large-mammal densities will have important cascading consequences for ecological communities.

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.

Habitat dynamics of beaver Castor canadensis at two spatial scales

Abstract We studied habitat dynamics of the Canadian beaver Castor canadensis in a boreal forest landscape in southern Finland at two scales: the beaver pond level and the landscape level. To explore

Simulated effects of the beaver on vegetation, invertebrates and ducks

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.
