Title: Ecosystem alteration of boreal forest streams by beaver (Castor canadensis): Journal: Ecology; Authors: R. J. Naiman, J. M. Melillo, and J. E. Hobbie; Date: 1986; Summary: For centuries beaver (Castor canadensis) have been altering stream systems in North America. In this study, Naiman et al. measured stream inputs and outputs and examined physical and biological parameters to determine the effects of beaver on riparian structure and function. Beaver were directly responsible for the presence of 53% of the fine wood in streams and the indirect effects of their dams (ponding, saturated soils, etc.) caused 50-60% of the remaining fine wood to be present in the stream. Ponds behind beaver dams retained large amounts of sediment, resulting in ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
