Ecosystem engineer restores trophic interactions: beavers alter landscape of risks and resources for megafauna

This study shows beaver reintroduction alters habitat use and trophic interactions among megafauna by creating spatial and temporal changes in resources and risks.

Rewilding beyond the wilderness: Beavers can restore stream biodiversity from urban to agricultural to natural landscapes

This study shows beaver-engineering increases biodiversity in streams across different land-use intensities, benefiting aquatic and semi-aquatic species.

Looking backward for the future: long-term population recovery, habitat associations, and future climatic vulnerability of the critically endangered Sino-Mongolian beaver (Castor fiber birulai) in China

This study tracks the population recovery and habitat preferences of the Sino-Mongolian beaver and assesses future climatic vulnerability using historical and projected data.

Beaver population decline on Michipicoten Island, Ontario leads to satellite-measured surface water area reductions

This study uses satellite data to show that beaver pond area reductions correlate with population decline on Michipicoten Island, Ontario, despite recent above-average precipitation.

Ancient sedimentary DNA shows more than 5000 years of continuous beaver occupancy in Grand Teton National Park

This study uses sedimentary ancient DNA to show beavers occupied two lakes in Grand Teton National Park for over 5000 years, with continuous presence at one lake and intermittent at another, while influencing local plant communities.

Postmortem findings of free-ranging North American beavers (Castor canadensis) reveal potential threats to California freshwater ecosystems

This study examines postmortem findings of free-ranging beavers in California to identify pathogens and health threats to freshwater ecosystems.

Environmental cues influence timing and location ofconstruction activity in a beaver damming complex

The paper tracks beaver construction activity in northwest Montana using drones, showing environmental factors influence timing and location of construction.

Ecosystem engineers cause biodiversity spill-over: beavers affect breeding bird assemblages on both wetlands and adjacent terrestrial habitats

This study shows beavers increase bird species richness and abundance in wetlands and adjacent terrestrial habitats up to 100 m from water edges.
