Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

Creator:: Ding, Pinghai
Abstract:: Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...

Collegiate student's epistemologies and conceptual understanding of the role of models in precalculus mathematics : a focus on the exponential and logarithmic functions

Creator:: Melendy, Robert F.
Abstract:: Collegiate student's conceptual distinctions of what define a mathematical and a physical model seems to be affected by the epistemological beliefs they hold about this knowledge. These beliefs seem to influence student's thinking and reasoning as they embark on problem solving activities in collegiate mathematics. Student's epistemological beliefs of mathematical...

Stand development of Cordia alliodora (Boraginaceae), a neotropical secondary forest tree in northern Costa Rica (1992-1996)

Creator:: Hummel, Susan Stevens
Abstract:: Cordia alliodora is used for reforestation programs and farm income in northern Costa Rica. This study investigated: 1) responses of C. alliodora associated with stand density, or trees/ha (TPH), and 2) plant diversity and biomass in the understory of C. alliodora plantations. Three Nelder plots, 31 temporary plots and 6...

Ectomycorrhizal inoculation of Douglas-fir nursery stock with commercially produced inoculum

Creator:: Hung, Ling-ling L.
Abstract:: Nine species of ectomycorrhizal fungi were grown in liquid media over a pH range of 2-7. Species fell into five major groups: (1) growth significantly best only at the optimal pH, (2) growth increased with increase of pH, (3) significantly best growth spans three pH units, (4) spans four pH...

Cryopreservation of Shoot Tips: Antioxidant Investigations with Rubus and Protocols for Mentha and Vaccinium

Creator:: Uchendu, Esther Eyiuche
Abstract:: Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...

Ecology of feral pigs on Santa Catalina Island

Creator:: Baber, Daniel W.
Abstract:: A feral pig population on Santa Catalina Island, California, was studied for 17 months beginning in July 1980. Density was estimated to be 21 to 34 pigs/km² (95% confidence interval) using capture-recapture techniques. Dry season home ranges determined from radio-telemetry data were small and differed significantly between boars and sows....

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...

Evaluation of various chemical treatments to prevent the abiotic deterioration of southern pine surfaces through outdoor screening trials

Creator:: Schauwecker, Christoph F.
Abstract:: Rapid discoloration and checking of wooden surfaces when exposed outdoors has caused wood to fall out of favor as an outdoor building material, especially in applications where appearance is important. The surface appearance of wood products exposed outdoors can be improved through the application of film forming coatings or by...

Seasonal distribution and environment of adult Pacific herring (Clupea harengus pallasi) near Auke Bay, Lynn Canal, southeastern Alaska

Creator:: Carlson, Harry Richard
Abstract:: The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a...
