Unequal summer use of beaver ponds by river otters : influence of beaver activity, pond size, and vegetation cover

Published by: Canadian Journal of Zoology

21st July 2007

River otters and beavers share freshwater habitats, though little research has tried to understand their relationship. Here, scientists conducted a study in a Canadian National Park to do just this. They found that otters preferred ponds currently inhabitated by beavers, particularly ponds which were bigger and had more plant cover. These ponds provide otters with prey and shelter. This suggests that beavers' habits of moving from pond to pond will likely affect otters' habitat patterns.

Detection of Francisella tularensis subsp. holarctica in a European brown hare (Lepus europaeus) in Thuringia, Germany

Published by: Veterinary Microbiology

20th July 2007

A bacterium which causes an infectious disease was detected in a brown hare from an area of Germany called Thuringia for the first time. Beavers are among the animals known to be the main carriers of this bacterium. The text discusses the implications of this finding for human public health.

Geomorphic changes upstream of beaver dams in Bridge Creek, an incised stream channel in the interior Columbia River basin, eastern Oregon

Published by: Earth Surface Processes and Landforms

9th July 2007

This study gathered evidence that encouraging beaver expansion can help with river restoration where the stream channel has undergone 'incision' - or dug deeper into the ground. This is a common issue in drier regions. Scientists measured how quickly and for how long sediment built up behind beaver dams in the USA. They also measured the impact on vegetation in these areas.

A beaver’s tale

Published by: Current Biology

3rd July 2007

This article briefly summarises the recent history of beaver reintroductions in Europe. From only 1,200 individuals at the 19th century, around 600,000 beavers now exist in Europe. This benefits ecosystems and economies through wildlife tourism. The author highlights how public engagement has been a feature of several re-introduction programmes to help foster positive attitudes towards beavers.

Ecosystem engineering by invasive exotic beavers reduces in-stream diversity and enhances ecosystem function in Cape Horn, Chile

Published by: Oecologia

22nd June 2007

Species invasions, like that of North American beavers in Chile, can significantly impact ecosystems. In Chile, researchers tested how beavers impact on aquatic invertebrate communities. Beaver ponds had less diverse invertebrate communities but more invertebrates overall. Areas downstream of beaver ponds were similar to natural, unimpacted areas. Beaver ponds increased invertebrate food in the water but made the habitat murky and uniform, reducing invertebrate diversity.
