Activity of European beavers (Castor fiber L.) in young pedunculate oak (Quercus robur L.) forests

Published by: Veterinarski Arhiv

20th July 2006

Six years after their reintroduction, scientists analysed the impact of beavers on young oak forests in Croatia. They found that 75% of plants were undamaged but six species did receive damage. They found that damage typically occurred 30-40 cm above ground on trees around 2-4 cm in diameter. In the article, the scientists also report on the type of damage and how far away from the bank the damaged trees were found.

Transition to independence by subadult beavers (Castor canadensis) in an unexploited, exponentially growing population

Published by: Journal of Zoology

11th July 2006

Over four years, researchers in the USA studied the movements, survival, and habitat of beavers in suburban and rural areas. Adult and juvenile beavers had high survival rates, but juveniles faced more risks. Deaths in rural areas were more often due to human activities and in suburban areas due to non-human factors like disease. Beavers' new areas were often smaller wetlands with less in the way of woody vegetation for beavers to eat on.

A framework for community and ecosystem genetics: from genes to ecosystems

Published by: Nature Reviews Genetics

1st July 2006

This article explores the idea that certain inherited traits in a single species of tree can impact whole ecosystems. These traits are known as "community and ecosystem phenotypes." The authors give an example of this process and beavers are central to it. By selectively foraging for poplars with low levels of a chemical called a 'tannin,' beavers drive a chain of natural selection across an entire ecosystem. Understanding these processes will help scientists understand the impacts of climate change. Please note, this resource is not open-access.

Influence of Beaver Activity on Summer Growth and Condition of Age-2 Atlantic Salmon Parr

Published by: Transactions of the American Fisheries Society

1st July 2006

Beaver dams, by shaping freshwater ecosystems, can affect the growth of Atlantic salmon. In a Canadian stream, researchers studied the impact of a beaver pond on the growth and maturity of salmon. Fish in the pond grew faster and stayed in better condition compared to those above or below it.

Optimal management of beaver population using a reduced-order distributed parameter model and single network adaptive critics

Published by: IEEE Transactions on Control Systems Technology

26th June 2006

This paper proposes a strategy for controlling beaver populations to balance their ecological benefits and the conflicts that can arise with human interests. The authors developed a computer model that considers the distribution as well as the migration of beaver populations. The method aims to be user-friendly and can be used by non-expert wildlife managers to maintain a healthy beaver population in specific areas.
