Modelling Early-Seral Vegetation Dynamics Using Climate and Soil Moisture

Creator:: Guevara, Claudio A.
Abstract:: Forest plantations in the Pacific Northwest are highly productive and have been intensively managed to maximize tree growth with practices such as Forest Vegetation Management (FVM). Different FVM regimes have been shown to enhance forest establishment by reducing the competition between the planted seedlings and early-seral vegetation. To better understand...

The Mountain Pine Beetle, Climate Change and Sustainable Forestry in the Northern Rocky Mountain

Creator:: Gillen, Amanda
Abstract:: Mountain pine beetles (MPB) have killed millions of acres of forest throughout the Rocky Mountain ecoregion in the United States and Canada and climate change may be intensifying outbreaks. Climate change can change forest ecosystems and dynamics by increasing drought conditions and intensifying heat waves. Due to changing climate conditions,...

Effect of organic fertilizers on survival, growth, chlorophyll and NDVI of Aniba rosaeodora Ducke plants in the Peruvian Amazon

Creator:: Vasquez Amasifuen, Cesar Paul
Abstract:: Aniba rosaeodora commonly known as rosewood is a tree species of great socio-economic value in the Amazon because it is harvested for the extraction of its essential oil, which is used in the production of cosmetics. Since rosewood is a wild species included on the Convention on International Trade in...

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...

Long-term Effects of Vegetation Management on Plant and Soil Derived Nutrient Budgets for Plantations of Four Western Conifer Species

Creator:: Callan, Cannon F.
Abstract:: Forest Vegetation Management (VM) is an important tool used in the Pacific Northwest (PNW) for reforestation. It has been well documented that VM increases seedling survival and crop tree volume growth. What is less understood, is how altering the plant community and successional trajectory affects the way the ecosystem uses...

Vegetation as Impacted by Soil Characteristics and Moisture in a Conservation Wetland, Willamette Valley, OR

Creator:: Aslan, Fevziye
Abstract:: Wetland degradation has negative influences on wetland functions and services. The understanding of wetland functions requires the intersection of two science disciplines, ecohydrology and plant physiology for a correct approach on wetland restoration and management. Although studies assessing ecohydrological relationships to protect wetlands are relatively common, studies evaluating both ecohydrological...

Water Use and Competitiveness of Senecio sylvaticus in Young Pseudotsuga menziesii Plantations in Western Oregon

Creator:: Cowden, Reed J.
Abstract:: Competition for soil water resources between newly planted Douglas-fir seedlings and aggressive early-seral plants, such as Senecio sylvaticus [L.] (Woodland groundsel, Senecio), can create drought conditions that impact tree seedling physiology, growth and likelihood of mortality. However, the specific impact of Senecio on soil moisture dynamics and inducement of water...

Effects of soil amendment treatments on survival and growth of four fast-growing tree species on degraded mine areas in the Peruvian Amazon

Creator:: Llancari Valenzuela, Yury Milagros
Abstract:: This paper aims to increase the knowledge on establishment practices for four fast-growing species (Guazuma crinita Mart., Eucalyptus grandis x E. urophylla, Bixa orellana L., Psidium guajava L.) in areas degraded by gold mining in the Peruvian Amazon. The study was carried out in Madre de Dios region, located in...

Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Ecotypic variation of Schoenoplectus pungens (Vahl) Palla in response to salinity and inundation

Creator:: Del Giudice Tuttle, Elena
Abstract:: Local adaptation in plants may hold the key to understanding the level of resilience of an ecosystem and probability of persistence of a species in the face of rapid anthropogenic changes in climate and disturbance regime. Clonal species are especially important in wetlands, one of our most productive and vulnerable...
