The presettlement hardwood forests and wildlife of Algonquin Provincial Park: A synthesis of historic evidence and recent research

Published by: The Forestry Chronicle

1st December 2004

This text compares the historical hardwood forests of a Canadian park with present conditions, focusing on changes in tree cover, gap structure, and riparian habitat. Most species still exist in the park, some have been lost. Beaver populations have declined sharply - suppression of fires in the park has led to a reduction in disturbance of river banks, reducing the amount of food available for beavers. The text also highlights how the plight of the beaver population is tied into the plight of the local wolf population.

Ice Processes Affect Habitat Use and Movements of Adult Cutthroat Trout and Brook Trout in a Wyoming Foothills Stream

Published by: North American Journal of Fisheries Management

1st November 2004

This study monitored the movements and habitat of two species of trout in a stream. Conditions in pools and beaver ponds were regularly measured during the monitoring period which ran from autumn into winter. Contrary to common belief, this study found that groundwater areas may not always provide stable winter habitat for the trout as they can be affected by subsurface ice. Beaver ponds offered ideal conditions. Conservation professionals should consider groundwater locations when planning habitat improvements.

Beavers and Biodiversity

Published by: Cambridge University Press

6th September 2004

This book chapter seeks to describe how different values can clash in ecological restoration initiatives by using the case of beaver re-introductions in Denmark. It examines differing views on the value of nature and biodiversity, and describes how biodiversity-based arguments are used by both proponents and critics of species restoration, who hold different understandings of biodiversity.

Food habits of wolves Canis lupus in Latvia

Published by: Acta Theriologica

1st September 2004

This article reports on a study of wolf diets in Latvia. From 1997 to 2001, these wolves primarily deer and boar, with some beavers. Their diet varied by season and region, with more wild boar in the east. They ate more diverse foods in summer. Domestic animals were rarely eaten, mainly as carrion in winter. Empty stomachs were common.

Distribution of Zooplankton along the Longitudinal Profile of Two Disturbed Small Rivers of the Upper Volga Basin

Published by: Russian Journal of Genetics

1st September 2004

This researcher describes how human activity and beaver behavior greatly affects the distribution of tiny aquatic organisms called zooplankton in two rivers in Russia. One of the places where these organisms are most abundant is in beaver ponds. The study uses a theory called patch dynamics to explain this uneven distribution.
