New resinicolous ascomycetes from beaver scars in western North America

Published by: Annales Botanici Fennici

1st January 2003

This paper describes three newly-classified species of fungi in the USA. These fungi grow in the resin of conifer trees which collects in the scars created by beavers. One of the species of fungi is also found in Northern Europe.

Beaver herbivory and its effect on cottonwood trees: influence of flooding along matched regulated and unregulated rivers

Published by: River Research and Applications

18th July 2002

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.

Survival, Fates, and Success of Transplanted Beavers, Castor canadensis, in Wyoming

Published by: Canadian Field-Naturalist

1st January 2002

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.

Beavers

Published by: Whittet Books Ltd

1st December 2001

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.

Genetic Divergence and Similarity of Introduced Populations of European Beaver (Castor fiber L., 1758) from Kirov and Novosibirsk Oblasts of Russia

Published by: Russian Journal of Genetics

1st June 2001

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.
