Field anaesthetic and surgical techniques for implantation of intraperitoneal radio transmitters in Eurasian beavers Castor fiber
Published by: Wildlife Biology
1st March 2004
Researchers implanted radio transmitters in 22 adult Eurasian beavers. They tested two different anesthesia combinations. One group experienced muscle issues and sensitivity to sound while under anaesthetic. The other group, with an added drug, had better muscle relaxation and didn't react to sound. One beaver died after surgery, but all others continued to live in their original territory unaffected by the surgery.
Beavers indirectly enhance the growth of Russian olive and tamarisk along eastern Montana rivers
Published by: Western North American Naturalist
20th February 2004
Researchers found that beavers preferentially cut down cottonwood trees over invasive species like Russian olive and tamarisk. They focus their foraging near river channels, creating sunny areas that promote the growth of the invasive species, leading to faster growth. The researchers warn that those wishing to reintroduce beavers along these rivers in Montana, USA, should consider the potential effect on invasive plant species.
Habitat Use and Preferences of Breeding Female Wood Ducks
Published by: Journal of Wildlife Management
1st January 2004
Researchers monitored 47 female wood ducks to understand their habitat use during the period of egg production. Habitat preferences varied between different ducks. Older ducks - and ducks making their nest early - tended to prefer beaver ponds as a habitat more than younger ducks and those who made their nests late. Overall, ducks adapted to different wetlands for breeding, and the authors suggest that habitat diversity is vital for their reproduction. Please note, this resource is not open-access.
Continuing Environmental Change – An Example from Nova Scotia
Published by: Canadian Field-Naturalist
1st January 2004
The last century of environmental changes in Nova Scotia is described, drawing on literature, community knowledge, and personal experience. The complex interactions of disease, human activity, and animal expansion are set out. The restoration of beavers is considered one of the major events of this history.
Associations of small mammals and amphibians with beaver-occupied streams in the Oregon Coast Range
Published by: Northwest Science
1st January 2004
Researchers studied how beavers affect vegetation, small mammals, and amphibians. They compared stretches of 5 streams in Oregon, USA - some occupied by beavers and some unoccupied. They found that beaver-influenced areas of the streams had more diverse plant life and had a higher presence of certain mammalian species. Please note, this resource is not open-access.
