Models of a four-species annual weed community : growth, competition, and community dynamics

Creator:: Roush, Mary Lynn
Abstract:: Models of weed communities aid in the development of weed management strategies and elucidate the processes and mechanisms that regulate plant populations and communities. A conceptual weed community model was developed to organize key regulatory life-history processes. Specific investigations focused on the processes of plant growth and competition, and relationships...

Spatial patterns of fuel management activities and their effects on wildfire behavior

Creator:: Kim, Young-Hwan
Abstract:: Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...

Greater sage-grouse reproductive ecology : linkages among habitat resources, maternal nutrition, and chick survival

Creator:: Gregg, Michael A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:: Lake, Frank K.
Abstract:: The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...

The Biology and ecology of weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana)

Creator:: Tarasoff, Catherine
Abstract:: Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...

Quaking aspen persistence in three Oregon landscapes

Creator:: Seager, S. Trent
Abstract:: Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...

Directing ecological succession : the role of competition in restoring semi-arid grasslands dominated by invasive plants

Creator:: Mangla, Seema
Abstract:: Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....

Effects of wildfire burn severity on soil microbial communitiesand invasive plant species in the Cascade Range of Oregon

Creator:: Hebel, Cassie L.
Abstract:: Fire suppression in the last several decades has resulted in unprecedented accumulations of organic matter on the landscape, leading to an increase in large, intense wildfires. This study investigated the soil microbial community (using phospholipid fatty acid analysis) across recently burned forests on the eastern slope of the Cascade Range...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...
