Linking time budgets to habitat quality suggests that beavers (Castor canadensis) are energy maximizers

Published by: Canadian Journal of Zoology

12th August 2016

This study tested a theory of how beavers forage by observing 27 beavers in Canada. They found that living in a higher- or lower-quality habitat (i.e. with more or less nutritious food) did not influence how much time beavers spent foraging. The time of year did have an influence, as may other factors which are suggested as future avenues of research.

The effect of sub-alpine landslides on headwater stream gradient and beaver habitat

Published by: Physical Geography

10th August 2016

In Colorado, USA, researchers studied the connection between landslides and beavers on small headwater streams. They found that streams with landslides were more likely to have beaver dams than those without. They identified that this was because landslides created parts of the stream which are less steep and more suitable for beavers.

Territory size and age explain movement patterns in the Eurasian beaver

Published by: Mammalian Biology

30th July 2016

In Norway, researchers tracked 25 beavers to understand their movement patterns in relation to territory size and age. They found that beavers with larger territories traveled farther, spending more time patrolling and foraging closer to the shoreline than those with smaller territories. Older beavers tended to spend more time near territory borders, likely due to a boldness which comes with experience.

Genetic monitoring of Eurasian beaver (Castor fiber) in Switzerland and implications for the management of the species

Published by: Russian Journal of Theriology

6th June 2016

This study examined the Eurasian beaver population in Switzerland, revealing that they came from two different genetic groups. Overall, the population had low genetic diversity was observed and the study showed that individuals up to 50 km apart were closely related. No evidence of North American beaver presence was found.

About possible ways of genes penetration from West Siberian beavers Castor fiber pohlei into Austria

Published by: Russian Journal of Theriology

6th June 2016

The genetic trace of West Siberian beavers had been found in the population of beavers in Austria, even though these two places are separated by over 3,000 km. This study looked at different types of genetic information to trace this back to a single female beaver which was brought to a Russian nature reserve in 1958.
