Detection of deforestation and land conversion and estimation of atmosperic emissions and elemental pool losses from biomass burning in Rondônia, Brazil

Creator:: Guild, Liane S.
Abstract:: Biomass burning associated with deforestation and land use in the Amazon, greatly contributes to emissions as well as depletion of elemental pools. We identified deforestation and pasture formation and quantified resultant burning emissions and terrestrial aboveground elemental pool losses during a period of early colonization in the vicinity of Jamari,...

Biomass and nutrient dynamics associated with deforestation, biomass burning and conversion to pasture in a tropical dry forest in Mexico

Creator:: Steele, Michael D.
Abstract:: The effects of deforestation and biomass burning in tropical dry forests (TDF) remain a little studied phenomenon. We quantified total aboveground biomass (TAGB), carbon and nutrient (N,S,Ca,P,K) loss under two separate fire severity scenarios; one early when the fuels were higher in moisture content, one later when the slash fuels...

Long-term Fuel Succession in the Sagebrush-steppe

Creator:: Reis, Schyler Ainsworth
Abstract:: Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...

Riparian vegetation composition and structure associated with channel morphology of headwater meadow streams in the Blue Mountains, northeast Oregon

Creator:: Toledo, Zachary O.
Abstract:: Relationships between the structure and composition of riparian vegetation with channel morphology were examined in three montane meadow streams in the headwaters of the Upper Grande Ronde River and North Fork John Day River in the Blue Mountains, northeast Oregon. Vegetation composition, root biomass, and channel morphology cross-sections were sampled...

Landscape level patterns in biodiversity : plant species and biomass structure

Creator:: Heider, Christopher
Abstract:: In the tropics, widespread deforestation and conversion of primary forests to agricultural and pasture lands has resulted in losses of composition, structure, and functions of forest landscapes. Deforestation in the tropics is typically preformed via slash-and-burn practices; the byproducts from combustion have been identified as the second-highest form of anthropogenically...

Aboveground biomass and ecosystem carbon pools in tropical secondary forests growing in six life zones of Costa Rica

Creator:: Cifuentes Jara, Miguel
Abstract:: Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...

Carbon Stocks and Soil Greenhouse Gas Emissions Associated with Forest Conversion to Oil Palm Plantations in Tanjung Puting Tropical Peatlands, Indonesia

Creator:: Novita, Nisa
Abstract:: This dissertation addresses gaps of knowledge associated with how ecosystem carbon stocks and greenhouse gas emissions are affected by land use land cover change in tropical peatlands. This was the first study that paired peat swamp forests with oil palm plantations and analyzed site scale variation on greenhouse gas emissions....

Ecology of woody riparian vegetation in tributaries of the Upper Grande Ronde River basin, Oregon

Creator:: Lytjen, Danna J.
Abstract:: Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde River basin, quantified several physical and biotic influences on woody riparian community composition and structure. The Catherine Creek study examined the association of woody riparian species with elevational and geomorphic gradients. The Meadow Creek study examined the...

Hydrologic and vegetation responses associated with restoration of wetlands in the Willamette Valley, Oregon

Creator:: Coleman, Gregory A.
Abstract:: I examined hydrological and plant community changes associated with the implementation of a restoration management plan in two riparian meadows located within an agricultural landscape of the central Willamette Valley, Oregon. I established exclosure fencing (a form of passive restoration) in one agricultural field and established fencing and plugged a...
