Mobility of Settlements and Elements of the Biological Signaling Field of Beavers (Castor fiber) in the Basin of the Tadenka River (Prioksko-Terrasny Nature Reserve)

A study that suggests a high density of the biological signaling field is a sign of possible depletion of food resources, and can explain how beavers can have such a large range.

Effect of Agriculture and Presence of American Beaver Castor canadensis on Winter Biodiversity of Mammals

This study compared various measures of biodiversity levels of mammals in the winter months between wetlands on agricultural land and wetlands, as well as wetlands with active and inactive beaver colonies.

Restoring wetland biodiversity using research: Whole-community facilitation by beaver as framework

Wetlands are declining worldwide, and there is a great need for their restoration and creation. One natural agent of wetland engineering is beavers.

Habitat engineering by beaver benefits aquatic biodiversity and ecosystem processes in agricultural streams

Dam building by beaver in degraded environments can improve physical and biological diversity
when viewed at a scale encompassing both modified and unmodified habitats.

The Beaver Facilitates Species Richness and Abundance of Terrestrial and Semi-Aquatic Mammals

Research article that used camera trapping and snow track surveying to investigate the facilitation of a mammalian community by the ecosystem engineering of the American beaver in a boreal setting.

Persistence at Distributional Edges: Columbia Spotted Frog Habitat in the Arid Great Basin, USA

Study that finds beaver-induced changes to habitat quality, stability, and connectivity may increase spotted frog population resistance and resilience to seasonal drought, grazing, non-native predators, and climate change.

Species Profile: Great Blue Heron

Short overview of the Great Blue Heron with a brief description of their reliance on beaver.

The Impacts of Beavers Castor spp. on Biodiversity and the Ecological Basis for their Reintroduction to Scotland, UK

A review that investigates the mechanisms by which beavers act as ecosystem engineers, and then discusses the possible impacts of beavers on the biodiversity of Scotland.

Influence of Beaver Dam Density on Riparian Areas and Riparian Birds in Shrubsteppe of Wyoming

Study that examines relationships between dam density, riparian area characteristics, and the riparian bird community in a semiarid landscape.

Reintroduction of Beavers Castor Fiber may Improve Habitat Quality for Vespertilionid Bats Foraging in Small River Valleys

Study conducted on small streams in forest areas of northern Poland to determine whether beaver ponds may improve habitat quality for bats

Aerial Multispectral Videography for Vegetation Mapping and Assessment of Beaver Distribution within Selected Riparian Areas of the Lake Tahoe Basin

Multispectral videography was used in this thesis to classify 10 streams in the Tahoe Basin and to determine how beaver dams affected their nearby vegetation.

Invertebrates in Beaver-Created Wetlands and Ponds

A study into invertebrates in beaver wetlands in the different regions of North America

A Critical Review of the Effects of Beavers Upon Fish and Fish Stocks

A review by the University of Southampton of how the reintroduction of beaver will affect fish in Scotalnd

Final ESA Recovery Plan for Oregon Coast Coho Salmon (Oncorhynchus kisutch) 2016

This recovery plan provides guidance to improve the viability of coho salmon to the point that it meets the delisting criteria and no longer requires ESA protection.

The Economic Value of Beaver Ecosystem Services Escalante River Basin, Utah 2001

In-depth report on how beaver could provide benefits to local residents and visitors well into the millions of dollars per year in Utah.

Beaver: Nature’s ecosystem engineers

This review summarizes how beaver impact ecosystem structure and geomorphology, hydrology and water resources, water quality, freshwater ecology, and humans and society.

Evaluation of the Ecological Impacts of Beaver Reintroduction on Aquatic Systems

By

Study on how beaver engineering and foraging has the potential to create unique and highly heterogeneous wetland and stream habitats
