The American beaver : a classic of natural history and ecology

Published by: Dover Publications

1st January 1986

This book, published only in 1986, contains a study originally conducted in 1868. Within, the author describes the beaver in incredible detail, from its anatomy to its psychology. Human-beaver interactions are also described, including information on how beavers can be trapped (although methods have, of course, evolved since the 19th century).

Blancan-Hemphillian Land Mammal Ages and Late Cenozoic Mammal Dispersal Events

Published by: Annual Review of Earth and Planetary Sciences

1st May 1984

This article collects, analyses, and summarises a variety of fossil evidence relating to the evolution of mammals in a specific period of ancient history. This period is called the Late Cenozoic era, and is around the time that the modern horse became the species we know today. At this time, around 5 milion years ago, the first species of beaver emerged. Other species of large, beaver-like animals also roamed the planet. Please note, this resource is not open-access.

Population Density, Colony Composition, and Local Movements in Two Sierra Nevadan Beaver Populations

Published by: Journal of Mammalogy

24th May 1983

This study challenged common beliefs about beavers' social organisation. By studying beaver colonies in two parts of the USA for two years at a time, it found that beaver colonies could have multiple adult members of either sex and that there was frequent movement between colonies. The authors suggested that such features may be related to the high population densities of beavers in the area. Please note, this resource is not open-access.

Modification of the Bailey Live Trap for Beaver

Published by: Wildlife Society Bulletin

1st March 1983

This paper describes modifications to a beaver trap. At the time of writing (1983), two traps - the Bailey and the Hancock - were commonly used to capture beavers. The Bailey was better for capturing trap-wary beavers but was limited to shallow water and often sprung without a beaver. The Hancock could be used at all water depths but was better for trapping beavers who were naive to trapping. The paper described amendments to the Bailey trap's release mechanism and lock.

Foods consumed by beavers in Crawford County, Pennsylvania

Published by: Journal of Wildlife Management

1st January 1962

This research aimed to understand what beavers' food preferences were in an area of the USA. The results showed a strong preference for two species called quaking aspen and red maple. On average, beavers consumed around 660 g of woody vegetation per beaver per day. The author estimated that one acre of aspen trees could support 10 beavers for a year.
