An evaluation of biological control of Linaria dalmatica with Mecinus janthinus in Oregon

Creator:: Park, Alexander
Abstract:: Dalmatian toadflax (Linaria dalmatica) has become a prolific invasive plant of rangelands in Oregon since its arrival in the early 20th century. In 2001, the Oregon Department of Agriculture initiated a release program promoting the distribution of the stem-boring weevil, Mecinus janthinus as classical biological control agent to reduce densities...

The use of remote sensing and Geographic Information Systems (GIS) in assessing changes in stream morphology and vegetation

Creator:: Laliberte, Andrea S.
Abstract:: Remote sensing and Geographic Information Systems (GIS) are well known tools for the study of time change analysis in natural systems. However, long-term studies of riparian systems using large-scale aerial photography are less common. The purpose of this project was to combine large scale aerial photography, GIS, Global Positioning Systems...

Rocky Mountain elk (Cervus elaphus nelsoni) behavior and movement in relation to lunar phases

Creator:: Woodside, Gail J.
Abstract:: Two small herds of Rocky Mountain (Cervus elaphus nelsoni) cow elk were, collared, observed, and spatially mapped for 10 continuous six day trials, conducted during 2008-2009. Five trials occurred during full moon periods and five trials during new moon periods. The elk were collared with 1 second interval GPS loggers...

Comparison of spatial distribution and resource use by Spanish and British breed cattle in northeastern Oregon prairie ecosystems

Creator:: Sheehy, Cody M.
Abstract:: We studied the distribution and habitat selection differences between Spanish breed (Corriente and Longhorn mix) and British breed cattle (Angus, Hereford). This study was located on the Zumwalt prairie during the spring and fall and along the Imnaha river for the winter. Each trial ran for two weeks and in...

Peavy Arboretum : an archaeological and historical investigation of a Willamette Valley landscape

Creator:: Hylton, Lindon B.
Abstract:: This thesis documents a period of ecological and cultural change on a Willamette Valley, Oregon landscape. In particular, this study examines the Peavy Arboretum area and the cultural changes that accompanied the transformation of the landscape from an oak savannah in the mid-nineteenth century to a dense Douglas-fir forest in...

Archaeological Investigations at the Seal Rock Site, 35LNC14 : A Late Prehistoric Shell Midden Located on the Central Oregon Coast

Creator:: Clark, Linda Ann
Abstract:: Seal Rock (35LNC14) is a late prehistoric shell midden site located on the central Oregon coast. Information derived from the faunal remains, radiocarbon dates, and location and size of the midden deposits suggest the site represents a late littoral stage of cultural adaptation. Analyses of lithic artifacts, and bone and...

Obsidian, archaeological implication for the central Oregon Cascades

Creator:: Lindberg-Muir, Catherine
Abstract:: Archaeological sites located on the western flanks of the centra1 Oregon Cascades are often characterized by the lack of temporally diagnostic artifacts and materials suitable for radiocarbon dating. Consequently, the temporal context of these sites remains largely unknown. Various researchers also have suggested that these open-air lithic sites have been...

Prehistoric Utilization of Thermal Springs in the Pacific Northwest

Creator:: Griffin, Dennis, 1953-
Abstract:: Natural thermal springs occur throughout the Pacific Northwest. The use and importance of this natural environmental feature to Native Americans prior to and during the period of initial white contact is examined. Ethnographic, archaeological, and oral historical information is described in an attempt to reconstruct the role of these naturally-heated...

Temperature influences on cattle distribution and behavior in the central California foothills

Creator:: Smith, Kelly Ryan
Abstract:: The effect of temperature on cattle behavior and distribution was studied in the foothills of California. To accurately understand changes in livestock behavior and distribution, five seasonal trials, each spanning three to four weeks were conducted beginning spring 2004 and ending spring 2005. The two spring trials and the fall...

Sediment production from forest roads in the upper Oak Creek Watershed of the Oregon Coast Range

Creator:: Amann, Joseph R.
Abstract:: Unpaved roads are sources of chronic sediment in forested watersheds. Bare soil on roads is exposed to erosion from rainfall and runoff Published research on sediment production from forest roads focuses primarily on road characteristics. Since water drives the mechanics of sediment transport, hydrologic variables should correlate with sediment production....
