Craniometric Features of the Population of European Beaver (Castor fiber L.,1758)

Published by: Slovenian Veterinary Research

3rd July 2019

This study looked at the skulls of 25 Eurasian beavers of both sexes to understand their head shape. The measurements showed some big differences between male and female beavers, and the researchers found an interesting dent in the back of the skull.

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

Published by: Global Ecology and Conservation

2nd July 2019

Ecologists compared beaver-modified with beaver-free sites in Finland to understand beavers' role in supporting other mammals. They found that beaver activity increased mammal species richness by 83% - species like moose, otters, pine martens, and weasels used beaver areas more, especially in winter.

The best snacks for kids: the importance of beavers Castor fiber in the diet of wolf Canis lupus pups in north-western Poland

Published by: Ethology Ecology & Evolution

19th June 2019

This study in north-western Poland found that, whilst adult wolves overwhelmingly ate ungulates such as deer, wolf pups ate much more beaver than their parents. This paper highlighted how more research was needed to understand how wolf diets change as they grow. Please note, this resource is not open-access.

Beaver-generated disturbance extends beyond active dam sites to enhance stream morphodynamics and riparian plant recruitment

Published by: Scientific Reports

31st May 2019

In the USA, researchers explored how beavers generate ecological 'disturbances' outside of the dam itself. Willow cuttings from beavers' chewing often ended up downstream, where they sprouted, trapped sediment, and stabilised riverbanks. The cycle of dam building and abandonment was shown to have been shaping the landscape for thousands of years, affecting habitat diversity and floodplain carbon storage.

Beyond Walden: The Hidden History of America’s Kettle Lakes and Ponds

Published by: Walker & Co

19th May 2019

Kettle lakes, formed by melting glacial ice, are common across northern USA, serving as natural wells with no significant streams. This book explores their cultural and ecological significance, and the threats they face as fragile ecosystems. During the colonial era, kettle lakes were prized for the beaver pelts that could be sourced from them. Please note, this resource is not open-access.
