Beavers promote calicioid diversity in boreal forest landscapes

Published by: Biodiversity and Conservation

22nd November 2016

Through their engineering works, beavers change forest ecosystems, creating diverse habitats and producing deadwood. This study compared the diversity of land-based fungi called calicioids in forests with and without beavers. Diversity was significantly higher in beaver sites, likely due to the abundant deadwood they provide. This showed that beavers' benefit land-based organisms as well as aquatic ones.

Why invasive Patagonian beavers thrive in unlikely habitats: a demographic perspective

Published by: Journal of Mammalogy

9th November 2016

Researchers studied invasive North American beavers in two habitat types in Patagonia: forests and the steppe. It found that colony size and offspring numbers were higher in the steppe, even though previously most people thought that that habitat was not very good for beavers. Beaver survival rates were high in all habitats. Overall, the adaptability of the beaver to different habitats is seen as crucial to its survival in Patagonia, and the authors suggest more research is needed on beavers in the steppe.

Morphological and neuroanatomical study of the mammary gland in the immature and mature European beaver (Castor fiber)

Published by: Tissue and Cell

1st October 2016

This study looked at the structure and nervous system of the Eurasian beaver's mammary gland. The research found similarities between juvenile and mature (non-pregnant) beavers, as well as similarities to other mammals' mammary glands. Please note, this resource is not open-access.

Short-term effects of tagging on activity and movement patterns of Eurasian beavers (Castor fiber)

Published by: European Journal of Wildlife Research

28th September 2016

Tagging animals can be great for monitoring beavers in their habitats but this study wanted to see if any stress in the tagging process affected beavers' behaviour. It found that overall activity levels decreased very slightly, but tagged beavers were moving similar distances and using as much of their territory as beforehand, suggesting minimal impact on beavers' behaviour.

The Eurasian Beaver Handbook: Ecology and Management of Castor fiber

Published by: Pelagic Publishing

15th August 2016

Written by experts, this book describes the ecology of beavers and non-lethal management options for mitigating any negative impacts beavers may have on human activity. With a focus on Britain, it describes the history of the Eurasian beaver before analysing the role of beavers in fostering biodiversity and reducing flood risk. A number of non-lethal management techniques are also described, providing valuable guidance for coexisting with beavers. Please note, this resource is not open-access.
