Non-native and native plant species distributions and variability along an elevation gradient in the Wallowa Mountains, Oregon

Creator:: Averett, Joshua P.
Abstract:: Invasion by non-native plants into natural areas is an important component of global change that threatens biodiversity and ecosystem structure and function. Mountains are currently among the least invaded ecosystems, however, these biodiversity hotspots are increasingly under threat of exotic plant invasion. Evaluation of plant species distribution patterns in mountain...

Predicting foundation bunchgrass species abundances: model-assisted decision-making in protected-area sagebrush steppe

Creator:: Rodhouse, Thomas J., Irvine, Kathryn M., Sheley, Roger L., Smith, Brenda S., Hoh, Shirley, Esposito, Daniel M., and Mata-Gonzalez, Ricardo
Abstract:: Foundation species are structurally dominant members of ecological communities that can stabilize ecological processes and influence resilience to disturbance and resistance to invasion. Being common, they are often overlooked for conservation but are increasingly threatened from land use change, biological invasions, and over‐exploitation. The pattern of foundation species abundances over...

Canyon Grasslands of the Hells Canyon National Recreation Area : How have they changed over time and what is their future trajectory?

Creator:: Pack, Samantha J.
Abstract:: The canyon grasslands of the Hells Canyon National Recreation Area (HCNRA) are a unique ecosystem within the Pacific Northwest Bunchgrass Region (PNWBR) with a long history of natural and anthropogenic disturbances including fire, invasive species introduction, historical livestock grazing, and cultivation. Even with this history, these canyon grasslands contain some...

Role of Peroxisome Proliferator-Activated Receptor Gamma on Prevention/Cure of Mastitis

Creator:: Trindade da Rosa, Fernanda
Abstract:: Mastitis is a major endemic disease in dairy cows resulting in significant economic losses for the dairy industry. The peroxisome proliferator-activated receptor gamma (PPARγ) is a nuclear receptor that is able to bind and be activated by natural (e.g., fatty acids) and synthetic (e.g. thiazolidinedione) compounds. PPARγ plays important roles...

Nutritional Management of Beef Cows During Late-Gestation to Enhance Offspring Productivity

Creator:: Marques, Rodrigo Da Silva
Abstract:: Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...

Aspen Drought Stress Response, Snow Cover and Soil Moisture Dynamics on an Oregon Bunchgrass Prairie

Creator:: Neary, Andrew
Abstract:: Quaking aspen, Populus tremuloides, has experienced severe declines in recent years in part due to the effects of changing climate and extreme drought. As the dominant deciduous tree in Western North American forests, aspen plays a critical role in forest biodiversity and ecosystem function. Therefore, the persistence of this species...

Activated carbon incorporated into herbicide protection pods as a seed amendment technology for revegetation

Creator:: Clenet, Danielle R.
Abstract:: Reestablishing native perennial vegetation in annual grass-invaded rangelands is critical to restoring ecosystems, especially following wildfires. Controlling invasive annual grasses is essential to increasing revegetation success; however, pre-emergent herbicides used to control annual grasses prohibit immediate seeding due to non-target herbicide damage. Thus, seeding is often delayed one year following...

The Ecological Recovery of Saguaro National Park after Removal of Cattle Grazing and Associated Succession

Creator:: Summers, Ryan J.
Abstract:: In the area that is now Saguaro National Park East, grazing began in the 1880's. Because of the impact to the iconic saguaro cactus as well as all palatable plant species in the area, ecological damage in the park were determined to be so great that anti-grazing conservationists challenged the...

Comparison of Common Ravens in Sage-grouse Core and Non-Core Areas: Assessing Predator Densities Related to Anthropogenic Features

Creator:: Revekant, Claire L.
Abstract:: Greater sage-grouse (Centrocercus urophasianus: hereafter sage-grouse) abundance and distribution in North America has declined over the last century. Many factors have contributed to this decline, including habitat loss and fragmentation from human development with an associated potential for increased predation. While human development has been connected to lower sage-grouse demographic...

Mycorrhizal Fungi on the Sagebrush Steppe: Benefits for Restoring Keystone Rangeland Plant Species

Creator:: Prado-Tarango, David E.
Abstract:: Arbuscular mycorrhizal fungi (AMF) are plant symbionts that associate with the vast majority of terrestrial plants species. The AMF colonizes the plant roots by penetrating the root cortical cells, where the fungi exchanges mineral nutrients with the host plant for photosynthates. This association exists as a complex system in which...
