Seasonal variation in the home range size of the Eurasian beaver: do patterns vary across habitats?

Published by: Mammal Research

1st March 2016

The study examined how Eurasian beavers use space across seasons and habitat types. By tracking 42 beavers in the Czech Republic from autumn to spring, researchers found varying home range sizes. Spring ranges were largest while winter ranges were smallest. Overall, habitat type influenced range size more than age or sex.

Beaver ponds’ impact on fluvial processes (Beskid Niski Mts., SE Poland)

This paper examines how beavers have affected a section of the upper Wisłoka River in Poland. It analyses changes in the shape of the river's channel and valley. The beavers also impacted how much sediment was deposited in this stretch of the river. Please note, this resource is not open-access.

Habitat engineering by beaver benefits aquatic biodiversity and ecosystem processes in agricultural streams

Published by: Freshwater Biology

11th February 2016

In Scotland, scientists aimed to understand the impact of dam-building in ecologically degraded streams. Dams led to an improvement in nutrient processing. Although there were fewer types of aquatic insects in the immediate dam area, at the landscape level insect diversity increased. Beaver activities can be helpful for restoring degraded streams and supporting biodiversity.

Beaver activity increases aquatic subsidies to terrestrial consumers

Published by: Freshwater Biology

1st February 2016

Beavers increase life in freshwater ecosystems. In this paper, scientists measured how beaver dams affect the flow of nutrients from water to land by measuring the amount of aquatic carbon in land-based animals. They found that sites with beaver dams had more aquatic carbon in nearby spiders and mice, showing how beavers impact nutrient flow between water and land.

A new large beaver (Mammalia, Castoridae) from the early Miocene of Japan

Published by: Journal of Vertebrate Paleontology

25th January 2016

Around 18 million years ago, an ancient relative of today's beavers lived in what is, today, Japan. This study reports on some of this animal's fossil teeth and compares them to other beaver ancestors - for example, this beaver had a thicker layer of tooth enamel than many of its relatives.
