KNOWLEDGE BASE

This book has received great reviews for its accessible writing style and visual style - with the authors including many of their own photos. As the name suggests, there is particular detail on the history of beavers, including how beaver meadows provided early colonisers in North America with level, fertile land for agriculture. It also explores the diversity of beaver ancestors, including now-extinct species of beaver which were as large as bears. Please note, this resource is not open-access.

This study compared beaver cottonwood-eating patterns and cottonwood tree distribution on two rivers in Colorado, USA: one free-flowing, the other whose flow is regulated by a man-made dam. On the latter, regulated river, cottonwood trees were both less common and more likely to be eaten by beavers. A controlled flood on the same river increased foraging because beavers could access the cottonwood saplings more easily.

This study assessed a relocation programme of 234 beavers in Wyoming, USA, between 1994 to 1999. Populations were successfully established at 13 out of 14 sites, but significant proportions of the relocated beavers died. Beaver age was an important factor in survival rate. The study shows that planning for losses from mortality and emigration is crucial for successful relocation.

This book discusses the reintroduction of beavers in Britain. The text covers beavers' biology, environmental impact, and reintroduction process. It provides insights into their history and behaviour, and has been praised for its engaging writing style. Please note, this resource is not open-access.

Researchers studied the genetic makeup of two introduced beaver populations from different regions in Russia. The researchers studied five specific points in the beavers' DNA. They found differences which were explained by the populations' history, interbreeding, and initial migration. Please note, this resource is not open-source.
