Total hydrocarbon emissions from lumber dry kilns

Creator:: Lavery, Mark Robert
Resource Type:: Masters Thesis

Nitrate and pesticide transport under pear production in clay and sandy soil

Creator:: Cao, Weidong
Abstract:: Groundwater contamination on irrigated land is of concern in this nation and around the world. In order to reduce the potential of groundwater contamination by agricultural practices such as irrigation, fertilizer and pesticide application, vadose-zone monitoring and sampling are needed. The main objective of this study was to evaluate impacts...
Resource Type:: Masters Thesis
Full Text:: transport has increased during the last few decades. Environmental and economic concerns have inspired the

Nitrate leaching and model evaluation under winter cover crops

Creator:: Minshew, Hudson F.
Resource Type:: Masters Thesis
Full Text:: Agricultural production can have significant impacts on environmental quality. Understanding the underlying

Harvestable moss : communities, hosts, and accumulation

Creator:: Peck, JeriLynn E.
Abstract:: With the increased recognition of moss as a secondary forest product has come an increased concern for the ecological ramifications of moss harvest. Three issues of primary concern are (1) characterizing the epiphyte communities impacted by harvest, (2) assessing the host preferences of these epiphytes, and (3) describing the availability...

Organic pesticide modification of the species interactions in an annual plant community

Creator:: Pfleeger, Thomas G.
Resource Type:: Masters Thesis
Full Text:: under current federal regulations, but reduces the environmental heterogeneity common in most field

Development and evaluation of the mallard duck as a model to investigate the immunotoxicity of environmental chemicals

Creator:: Fowles, Jefferson R.
Resource Type:: Dissertation

Application of nonequilibrium ecology to managed riparian ecosystems

Creator:: Stringham, Tamzen K.
Abstract:: Seasonal trends in water table level and soil moisture for four plant community types within an irrigated eastern Oregon riparian zone were described. Aboveground biomass, species composition, litter, percent bareground and percent basal cover of key plant species and life forms were measured. The relationship between water table levels and...

Full Text:: ). Friedel suggests that environmental change can be discontinuous, with thresholds between alternative

Metal and organic emissions from RDF and large volume contributor combustion

Creator:: Lee, Taejin, 1961-
Abstract:: The use of municipal refuse (RDF) as fuels has received widespread attention for reason of its energy equivalence and the increasing lack of available landfill sites. The principal obstacle to the construction of combustion facilities is that RDF produces toxic compounds, including heavy metals and such organic compounds as PCDD...

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...
