One of the less studied positive interactions among organisms is facilitation. Facilitation may have significant impact on diversity of species especially in low productive environments. We studied the effects of well-known facilitator and ecosystem engineer, the North American beaver ( Castor canadensis ), on small mammal assemblages in the boreal zone. The small mammals, namely voles, mice, and shrews, were trapped over 2 years in ten beaver-modified habitats and in ten control sites…

How beavers affect riverine aquatic macroinvertebrates: a review

Background As ecosystem engineers, the construction of dams by beavers alters stream habitat physically and biologically, making them a species of interest for habitat restoration. Beaver-created



The beaver facilitates species richness and abundance of terrestrial and semi-aquatic mammals

Spatio-temporal patterns of habitat use in voles and shrews modified by density, season and predators.

It is concluded that intrinsically differential habitat requirements and flexibility to modify habitat use facilitate the coexistence of the two competing vole species in mosaic landscapes consisting of boreal forests and open habitats.

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.

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.

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.

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.

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.

Unequal summer use of beaver ponds by river otters : influence of beaver activity, pond size, and vegetation cover

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.

The Impact of Spacing Behavior in Microtine Rodents on the Dynamics of Least Weasels Mustela nivalis: A Hypothesis

The hypothesis that the differences in the social behavior between the two main groups of vole prey, namely Microtus and Clethrionomys, could be a probable reason for the least weasel's dependence on some MicroTus species is proposed.

Food Availability and the Diet of the Common Shrew, Sorex araneus, in Britain

The decrease in population density and body weight of shrews in winter was not accompanied by a decrease in biomass or numbers of invertebrate prey, and an increase in abundance of adult coleopterans was accompanied by an increased in predation by shrews.
