The ecological role of beavers (Castor canadensis) in a Southwestern desert stream
The ecological impact of beavers on a stream in the southwestern United States was investigated to determine if beavers have impact on community and ecosystem level processes in a manner similar to what has been documented in more mesic regions. Specifically, my goals were to determine: (1) whether …

Movement and survival of chinook salmon fry stocked in a stream with natural barriers to anadromous fish migration
… of fry. In 1988, fry also were stocked into beaver ponds connected to the stream. Each group of fry contained coded-wire tagged individuals, identified by stocking location. Fry movement was almost entirely downstream, with a substantial emigration during a spring flood immediately after the …

A Study of Beaver Pond Morphology and Site Characteristics After Disturbance in Eastern Glacier National Park, Montana
… been conducted on alterations or disturbances to beaver ponds, which is important to understanding beavers’ interactions with the environment. Three sites with beaver-pond sequences in Glacier National Park in northwest Montana were chosen for study, including sites near Saint Mary Lake, Lake …

A damming history: an analysis on the legacy effects of beaver dams on the composition and structure of a montane riparian ecosystem
… As an "ecosystem engineer," the American beaver (Castor canadensis) increases heterogeneity in riparian systems through dam-building activities, resulting in diverse wetland complexes. This study explored the impact that historic, off-channel beaver dams have on the structure and …

THE LIFE HISTORY AND ECOLOGY OF RIVERINE SOCKEYE SALMON (ONCORHYNCHUS NERKA) IN A LARGE FLOODPLAIN RIVER
… succession, and ecosystem engineers, notably beavers, that create dynamic and biophysically complex off-channel rearing and spawning habitats. Sockeye salmon (Oncorhynchus nerka) display some of the most variable life history traits of all Pacific salmon, using lake and river rearing …

Geospatial and field-based techniques for physical geography and environmental change
… 2 is a recently published study of historical beaver activity and hydrological patterns at the rare and imperiled Cranberry Glades Botanical Area, a high-elevation peatland in the Allegheny highlands of West Virginia. We used Lidar and Geomorphon analysis to reconstruct shifting patterns of …
